Tascam DR -100MKIII


A minor update to a piece of gear doesn’t usually generally trigger a re-review, but new editions of the venerable Tascam DR-100 have been an exception. The original DR-100 was one of our favorite recorders when it came out (with a few reservations) and then the DR-100mkII had some significant improvements in audio quality.  It’s been one of our go-to recorders at Transom, with a good balance of features, performance and price. But oddly, the mkII was missing a few capabilities included on other Tascam recorders, as well as models made by competing companies.

So, we were curious to see what functionality the mkIII update would add, and whether it could stay competitive with the other recorders currently available.

Tascam DR-100mkIIIAs so often happens, the update of this recorder is a mixed-bag. It’s mostly good: the mic preamps and analog-to-digital converters have been noticeably improved, giving this recorder excellent sound quality with almost any microphone, even low-output dynamic mics.

Dual recording has been added, helping to protect against distortion resulting from unexpectedly loud peaks. And it’s still a fairly intuitive recorder to use, with many common functions controlled by easy-to-access hardware switches.

But a few important functions have moved to menu control, requiring a few button-pushes and scroll-wheel turns. Recording with one external microphone is especially problematic: audio only appears in one channel of the headphones, making it very difficult to monitor effectively (although there is a work-around – see below…)  And the improved performance comes at a price. At press time, this recorder sells for $400, significantly more than the DR-100mkII (~$235) or the DR-60D (sometimes less than $200) or the Zoom H5 (~$270).

What do you get for that extra investment?  Here are some details.

The most-useful improvements:

  • The input circuitry is improved, offering more gain, and cleaner sound. It can provide hiss-free recordings with practically any microphone, including low-output mics like the Electrovoice RE50.
  • It’s capable of recording at very high sample rates (up to 192 kHz). That’s of questionable value in a recorder like this, but some users may find it of use.
  • DR-100mk3-Input controlThere’s no more “low-medium-high” input gain-range switch — input gain is controlled only by the input gain knob.
  • The two nested input knobs have been replaced by just one, still positioned comfortably under the thumb, when the recorder is held in the right hand. A front panel switch makes it possible to adjust just the left channel, or the right, or both channels at once. Gain settings for each channel can be offset if using two mics with differing sensitivities, or if recording two subjects with different volumes.
  • Two types of dual recording are possible: making a safety recording at a lower level, to guard against loud peaks; or recording a WAV and MP3 version at the same time.
  • The display screen is larger, and easier to read, with helpful information clearly visible.
  • DR-100mk3-Input Gain LightsNew input level indicator lights near the external mic jacks offer a quick and obvious indication of audio present, close-to-peak (-6 dBfs), and over.
  • The external inputs are now XLR/quarter-inch “combi” jacks, allowing connection of both mic and line-level sources. (Line-level input signals should be connected to the quarter-inch jacks; mic-level signals should use the XLR jacks.)
  • The external mini input can now be set, in a menu, to accept mic level or line level.
  • Switches formerly on the back of the recorder have been moved to more convenient, and logical, locations on the front or sides of the unit. The phantom power switch is now located in between the mic inputs. The speaker on-off is now located near the volume dial and headphone jack. The limiter switch is now on the face of the unit, next to a pad switch and an input level control.
  • There are small bars on the bottom of the recorder that will allow the connection of a shoulder strap. Hanging the recorder from a strap places the screen in an inconvenient position, but the gain-indicator lights will still be clearly visible, at least providing some feedback about audio levels.
  • The unit can now operate fully on USB power. Earlier models could only charge the internal battery via USB.
  • The internal rechargeable battery can operate the unit for an impressively long time. Actual operating time will vary depending on many factors, including whether phantom power is being used, what file-type is being recorded, whether headphones are being used, among other variables. In our tests, recording from the built-in mics to a WAV file, the internal Lithium battery kept the recorder running for almost 12 hours continuously. Operation then automatically switched over to the two AA batteries. Those batteries only lasted about two hours. Connecting an external mic and turning-on phantom power might cut that record time in half, but if you keep the internal battery charged-up, the recorder should have plenty of power for a solid day’s reporting.  Different kinds of rechargeable AA batteries can provide longer operation times than standard Alkaline AAs.



Things that remained the same (for better or worse).

  • It’s approximately the same size and shape, although it’s heavier, probably due to the new internal battery. DR-100mk3-Uni Mics
  • Many controls remain as hardware switches, rather than menu items, allowing for quick adjustments and immediate confirmation of settings.
  • There’s still a decent built-in speaker, which can be handy for quick checks, logging, or transcribing.
  • The unit can still be powered via an internal rechargeable battery, or by two AA batteries (or by USB, which is new).
  • Latching XLR inputs assure a secure connection.
  • Built-in Unidirectional microphones are good quality, well-suited for recording ambiences and performances.
  • Built-in Omnidirectional microphones are noisy and tinny.
  • There is an S/PDIF digital input, which is increasingly rare on portable recorders.

Sadly, there are a few steps backward, and curious omissions.


  • DR-100mk3-Input MenuThe input source selection is no longer made with a hardware switch, it now requires accessing a menu. To be fair, there are more input options, making the previous versions’ multi-position switch less practical, but it’s unfortunate that menu navigation is now required for something so fundamental. Thankfully, navigating the menus for changing the input settings is fairly easy and logical.
  • The designation of MIC and LINE vs. EXT MIC and EXT LINE is not completely obvious.  EXT is for mics or line-level signals connected to the minijack on the top edge of the recorder, and choosing mic or line will set the gain-range appropriately.  MIC makes the XLR jacks on the bottom of the recorder the active input, and LINE is for the quarter-inch inputs at the center of those combination jacks.
  • The headphone amp is seriously under-powered. It’s hard to get much volume in the headphones, especially when recording with one mic. UPDATE! A helpful reader pointed out that there’s a new headphone level control, in addition to the thumbwheel on the side of the recorder. It’s semi-hidden in a menu: I/O SETTINGS>>OUTPUT ATT. On most recorders, output attenuation will simply reduce the output level of the mini-jack line-out, which is helpful when feeding audio to a video camera. And this menu will let you control that level, but there’s ALSO a setting for headphone output level. The overall headphone volume can be reduced by 10 or 16 dB, or there’s a setting called “EAR PROTECTION.”  The recorder’s default settings have “ear protection” selected, which drops the output level significantly.  Set the headphone output attenuation to zero, and you’ll get plenty of sound in the headphones.
  • When recording in mono to one channel — a common interview scenario — the sound only appears in one ear on headphones. This makes it very difficult to monitor confidently. UPDATE! Another helpful reader asked if there was a downside to using “MONO-MIX” (set in the FILETYPE menu) when recording with only one microphone. This mode combines the left and right channels into a mono file, and routes sound from each input equally to both channels of the headphones.  In theory, this is bad practice: recording an “empty” track into the mono mix file can add noise. This used to be a real problem on some older recorders.   But in practice, on the DR-100mkIII, any noise created by the unused channel is so low that it’s inconsequential, so using mono-mix mode when recording with one mic is a viable workaround.  Just to be safe, I’d recommend turning the input gain down on the unused channel, the new Input level switch makes that easy to do.
  • The internal rechargeable battery is no longer removable. With the new battery’s relatively long life, and the ability to switch to AA battery power (or USB), that’s probably not going to be a huge problem in day-to-day use, but it was nice to have the ability to swap-in a spare, rechargeable battery. Additionally, rechargeable batteries tend to fail eventually, and it will be more complicated to update that battery if its performance falls.
  • The internal battery takes a long time to charge: several hours to fully-charge an exhausted battery.
  • Although the recorder can now make two stereo recordings at once, either as a reduced-level safety recording, or as a WAV-plus-MP3, this recorder does NOT allow 4-track recording from the built-in mics and the external inputs at the same time. The (much cheaper) Tascam DR-40 allows this, as does the DR-70D, as well as most of the Zoom recorders, such as the H5 or H6.
  • The current record settings, such as mono or stereo, are not reflected in the display until the record button is pushed. The correct information appears when that record-ready button is pushed, but it’s confusing that the display doesn’t accurately reflect the record mode until one is actually about to record.

Sound samples:

Ultimately, the most important issue is how recordings made on the device sound. The good news is that in most scenarios, the improvements to the mic preamps and converters are clearly obvious. The sound quality, in particular with external microphones, is excellent. Even low-output mics, such as dynamic omni mics, can be used with this recorder without turning the input gain controls all the way up, and without hissy background noise degrading the recordings.

Strangely, that pristine sound quality is not as apparent when using the built-in microphones. The unidirectional mics still sound pretty good, but do not seem as quiet as mics plugged into the external XLR inputs. Here are some examples:

Listen to “Dynamic Omni Mic”
Listen to “Dynamic Cardioid Mic”
Listen to “Shotgun Mic”
Listen to “Condenser Cardioid”
Listen to “Built-In Unidirectional Mics”
Listen to “Built-in Omnidirectional Mics”


The Tascam DR-100mkIII offers some real improvements over the earlier versions, and over competitors in the market. The sound quality is quite fine, and the operation is intuitive. Menus, when one needs to delve into them, are logically-arranged, and making changes is relatively quick and easy. The new rechargeable battery provides impressive performance: in most cases one could record for a whole day on a single charge. It’s unfortunate that the battery cannot be easily replaced, but its long life might be a reasonable trade-off. Conversely, operating on two AA batteries is a disappointment, we only got a couple of hours of continuous recording before the pair of new Alkaline batteries went dead.

The biggest downside of this recorder is the headphone monitoring. Levels overall are low, making it hard to make critical assessments of mic placement and background noise. Even worse, if recording with one mic, the audio only appear in one ear of your headphones. I’m hopeful that the single-channel problem could be addressed with a firmware upgrade, but I’m afraid that the weak output levels might not be easily fixed. There are possible work-arounds for these problems, but one shouldn’t have to add external devices and adapters simply to monitor recordings. Perhaps there are some specific headphones that work better than others with this recorder, but the industry standard Sony 7506 headphones, which can generally produce a very healthy level from most headphone outputs, are left sounding a little weak when connected to this recorder.

Those monitoring problems make it hard to wholeheartedly endorse this recorder, but the recordings it can make are quite impressive. The high-sample-rate recording that this recorder is capable of is of little use in most journalistic and documentary projects, but the overall quality of the mic preamps and analog-to-digital conversion is a real improvement from the earlier models. The DR-100mkIII can make clean, excellent-quality recordings with a wide array of microphones, including the dynamic mics that are often problematic with small portable recorders.

The Tascam DR-60D, and DR-70D offer good recording quality too — maybe not quite as good as the DR-100 mkIII, but still very good, and for less money. However, the design of the DR-100 mkIII may be more appealing in some contexts. If you intend to use the built-in mics, the DR-100 is a better choice: the DR-60D doesn’t have any, and the DR-70D’s are positioned poorly for hand-held use.

The most direct competitor is the Zoom H5, which has a similar size and configuration to the DR-100, and has a few extra tricks (four-track recording, interchangeable mic heads) at a lower price. The Zoom H5 is a good-sounding recorder, especially when using the built-in XY stereo mics, but the DR-100 mkIII has more clean gain for external mics than the H5. If sound quality is your primary concern, especially if you use a dynamic microphone, the DR-100 mkIII is your best choice.

    Thanks, as always, Jeff!

    As a workaround for monitoring one mono channel, I just switch to Mono Mix on the DR-100 MkIII and can hear the recording in both channels of the headphone. Is there a drawback to doing this?

    • jeff towne



      Hi Ed,
      There’s conceptually a drawback to using Mono-Mix: you’re recording an “empty” channel, and that can sometimes add noise to your recording. In fact, that was a big problem with some earlier recorders, especially some of the Zoom models, you’d end up with noticeable hiss added into the recording even though one of the channels was theoretically recording nothing. So my knee-jerk reaction is that you don’t want to be in mono-mix mode when only using one microphone.

      That said, this recorder is quiet enough that you probably can do this without any serious degradation of the sound. The “empty” channel is probably not producing enough noise to worry about. Just to be safe, I’d use the input gain control switch and knob to turn that empty channel’s input down (it won’t go to zero, but turn the gain down as low as it will go, just to reduce the chance of stray noise.

      I’ll give it a try and report back here. From a purist’s standpoint, I don’t like the idea, but from a practical angle, it’s almost certainly fine. And I’m generally more in favor of the practical perspective! So, thanks for the reminder!

      You could also use a Y-cable or splitter to create two XLR outputs from one mic, but Y-cables sometimes cause noise problems, and a good splitter creates additional bulk. – And it shouldn’t be necessary, there ought to be a simple mode on the recorder that only records one of the channels and routes the audio to both headphones.

      And even in mono-mix or stereo, I still think the headphone amp is weak.

      Despite that problem, mono-mix probably is a reasonable work-around for the one-mic scenario. Thanks again for suggesting it!

    Hi Jeff,

    I recently purchased this recorder and the headphone limiter comes turned on. Turn it off in the menu and you can get as loud of a signal out of the headphones as you need.

    • jeff towne



      Wow! That setting is new on this unit, and hidden under “Output Attenuation” in the menu. I had seen that setting, but assumed that it was just for the line level output – which it IS – but ALSO for adjusting the range of the headphone output. And as you say, the unit ships with the headphones set to “Ear Protection” which significantly reduces the level of the headphones.

      I had read the manual, but missed that the output attenuation wasn’t just for the line out. That’s often helpful for matching the input requirements of DSLRs and other video cameras. But it’s rare to have headphone level controls. Sound Devices recorders have headphone limiters, among other monitoring options, but none of them reduce the overall level so seriously.

      So – huge thanks, Sam – that makes a big difference in the viability of the recorder! That’s a big enough thing that I think I’ll need to update the review.

      And it’s a valuable lesson for me: stop assuming that I know what any given section of the boring manual is going to say, and actually read it more carefully!

      • Sam Eaton


        Thanks, Jeff. I really love this recorder but one other quirk is that if you’re running phantom power for an external XLR mic and have a lav receiver going into the second channel you get a mean buzz on the lav because of the phantom power going to both XLR inputs. A bummer that was never an issue with the Zoom H4n. And not an issue at all if you’re not using phantom.

        And I think the left channel only headphone monitoring is a firmware fixable quirk because when you go into the “REC SETTINGS” menu and select “MONO-L” under “FILE TYPE” you get a strong signal through both right and left headphones. But then if you power down and power back up again it only goes to the left signal. So you have to reselect “MONO-L” every time you power back up if you want to hear the left channel recording through both headphones. That leads me to think it’s a software flaw. Any chance you could alert Tascam about this so they can fix it in a firmware update???

        Thanks again, Jeff. This is all very helpful.

        Hi Sam, those are both interesting, and troubling, scenarios! I’ve very rarely had phantom power cause problems even when it’s not needed, but I’ll have to test out some of those combinations and see if I can replicate your problem, and more important, find a work-around! And the quirky re-start thing to keep configurations is weird… I was having a similar problem with the DR70D, phantom wouldn’t apply at first, but stopping and re-engaging record would do it. I think they’re having some programming quirks! But yeah, here’s hoping they can tune these things up in a firmware upgrade. I’ll send Tascam a note, but I’m not sure if they’ll give me any special attention! Thanks for the info…

      • Mark Brandish


        It seems Tascam fixed the headphone output settings being saved on power off when “REC SETTINGS” menu, “FILE TYPE”, “MONO-L” is selected. I’ve just updated the firmware on my DR-100mkiii to V1.01 which is available as a download from Tascam at http://tascam.com/product/DR-100mkIII/downloads/.

        I now get output to both left & right headphones after restarting the device once I’ve selected the Mono-L settings.

        The release notes with the firmware just state that “Operation reliability has been improved.” so not sure what else has been changed.

  • Phillip Schreibman



    Hi Jeff,

    Actually you can remove the built-in battery. Download this manual:


    and you will see on page 5 the instructions for doing so.

    Thanks for your reviews!

    • Jeff Towne



      Well, kind-of…

      You’re absolutely right that you CAN take the battery out, but Tascam doesn’t seem to sell replacements, and it’s not a simple procedure, you need to completely discharge the battery, then take out several screws, etc. It’s certainly not a quick swap you could make in the field when you need more recording time, like you could with the original DR-100 and the mkII. That was the contrast I was trying to make, I carried an extra rechargeable battery with me so I could do a quick swap if I blew through both the rechargeable and the AA batteries, which was not uncommon, the original rechargeables didn’t last anywhere near as long as they new one does.

      The battery removal process for the DR-100mkIII seems to be an environmental concern when you’re disposing of the recorder, and want to properly recycle the battery.

      That said, you’re right to point out that it’s possible, maybe at some point Tascam will offer replacement batteries, which won’t work as hot-swappable spares, but at least could restore the performance of the recorder if the battery is weakening before the rest of the device is (as has happened to me with cell phones, and a few other devices I’ve owned over the years, including the M-Audio Microtrack flash recorder, which also had a built-in rechargeable battery.)

      • Phillip Schreibman


        You’re right, it’s certainly not easily swappable, but at least it is a user-serviceable part that will, as you say, keep the unit working when the original battery dies. And it may turn out that the battery is widely available.

  • Ashley



    Nice article and nice to hear the unit work with different mics. I train volunteers for free at a hospital radio station in the UK and I’ll be starting up a mini radio package making course soon. (Again doing this for free) The only trouble with this unit is the cost. At £330 for the Tascam and say £210 for a Beyer Mic the price range is way too expensive for hobbyists / students / even me! LOL Cracking website you have here though!

  • Lucas



    I just purchased this. When I switch to the omni mics I’m getting a very loud buzz from the left channel. The buzz gets even worse if I touch the unit in a certain place (the little protective cage for the left unidirectional mic). I’m thinking I just got a bad unit. Anyone else have a similar issue?

  • Douglas



    I originally purchased a dr100 mII but returned it because the preamps were so poor; I had to turn it up to almost 100% gain to get a usable signal with a rode ntg1. I replaced it with a zoom h5 which I am very happy with. I would also disagree with the author with respect to the relative sizes of these two recorders; in my hands the h5 seems much smaller than the dr100.

    Considering the fact that the dr100 mIII is significantly more expensive than the h5 is the difference in audio quality worth the difference in price?

  • Sheldon Sanders



    The M/S monitoring was a selling point for me. M/S monitoring only works with mic inputs though. This is not a problem for anyone using the unit for standalone M/S recordings, but, even though the unit’s preamps are very good, I would still like to have the option of using an external preamp to record and monitor in M/S. With M/S monitoring selected and input set to line the MKiii just outputs undecoded mic signals to the right and left headphone channels. You can fool it into decoding the M/S array from line inputs if you enter the function menu, select M/S monitoring, and make a change to either the mid or side signal level. For some reason that will trigger M/S decoding, but as soon as you exit the function menu the monitor ouput reverts to the undecoded mid and side mics. Overall it’s a very nice unit, especially for standalone use. If they add M/S decoding for the line inputs in a future firmware update it will certainly make it even more useful.

  • Thomas



    I think the mono monitoring issue is a software bug. Right after I change the recording mode to Mono-L, it works fine and I get to hear what I’m recording on both ears. But when I turn the unit off and on again, there’s only sound on one ear. Also, when I’m using Mono-R recording doesn’t work after rebooting the device. This means I can’t go into an interview situation without navigating the menu first, changing the recording mode to stereo and back to mono.

    I reported this to Tascam months ago, right after the device came out and they still haven’t fixed it (while they did fix another bug with a firmware upgrade). All they said is, that I could send the unit in at my own expense so they can repair it.

    Also, one big downside is the manual which isn’t worth the paper it’s printed on. Some menu items are not self-explanatory (e.g. A/D Filter: FIR 1 or FIR2) and the manual isn’t helpful at all.

    Hi Jeff.
    Greetings from DaNang, Vietnam.
    I brought my Tascam DR 100 MK3 to capture street sounds, ambiences, nature, noise, vocals…. I’m a sound addict 🙂 – I’m constantly recording.
    I’m pleased to report the Tascam is operating perfectly in heavy humidity.
    I’m recording with the onboard unidirectional microphones at the 24/192 sample rate.
    I’m very happy with the results.
    Thanks again for your detailed reviews Jeff!

  • Greg



    This was a very helpful review!

    I do have one question and don’t know if you can answer.

    As far as the Digital Filters go, the FIR1 / FIR2 / SD1 / SD2, if I am using the recorder to record a conversation or dialogue, any suggestions on which on to use. I am not really understanding the idea of sharp versus slow roll-off outside the audio band. And when one might be preferable to another. It seems like if you want something rolled off, it would be more gradual than sudden. So I don’t get sharp versus slow.

    Thank you!

  • Christopher Jensen



    I purchased one about four months ago to replace a trusty Marantz. Liked the features and it got great reviews. I thought it was terrific until the release for one of the XLR inputs fell out. This from a unit treated very gently and carried in a Domke bag when not being used. Short version is that I’m looking at someplace around $150 in repairs – including shipping and insurance – on a unit that only cost $400. The warranty was only good for the parts, which the repair tech said were not available from Tascam. Plus, the tech said fixing it required moving a part that broke what he thought was a fragile ribbon connector. No, Tascam did not have that part, either. So, at last report the tech is going to rewire it himself.

    • Christopher Jensen



      Here’s an update to the problem I wrote about above. Heard from Tascam and it is replacing the unit, which is how quality manufacturers handle such problems.
