Portable and Powerful — This Mixer Does It All

Whether you want to capture a rehearsal, produce a quick demo, or create a great-sounding concert recording, Zoom’s LiveTrak L20R makes it easy. It enables you to record up to 22 individual channels directly to an SD card, supplies you with custom headphone mixes for up to six band members, and delivers a polished live mix — complete with studio-quality effects. With the L20R, you can finish your entire project in-the-box or transfer all 20 discrete tracks to your DAW for editing and mixing. Beyond that, you can use the L20R as a rock-solid 22-in/4-out USB audio interface for your Mac, PC, or iOS device. What’s more, the LiveTrak L20R boasts compatibility with Zoom’s Remote Mixer app, allowing an FOH engineer and six musicians to take command of their own mix via iPad.

Note: iPad required for operation. Compatible with all iPad Air models, iPad Mini 2 and later, iPad Pro, and iPad (2017), running iOS 10.3.3 or newer.

Craft professional-quality live mixes

The LiveTrak L20R makes crafting pro-quality live mixes easy. Each of its 20 discrete channels features a 3-band mid-parametric EQ and 20 built-in effects. Sixteen combo jacks accommodate both XLR and 1/4" connectors and are loaded with great-sounding mic preamps and dedicated compressors. Channels 1–2 offer hi-Z inputs for your electric guitar or bass, while channels 17/18 and 19/20 have TRS and RCA connectivity for keyboards and other audio devices. You also get clear 12-segment LED metering for keeping an eye on your levels.

Produce great-sounding recordings

Recording your entire band has never been simpler, thanks to the Zoom LiveTrak L20R. Twenty-two individual tracks are conveniently captured onto an SD card at 24-bit/96kHz. You can then mix and overdub directly within the L20R using its onboard effects or transfer the entire project to your DAW for further editing and processing. If you're performing live, you can record and mix your show simultaneously. At Sweetwater, we found that the L20R makes recording incredibly fast and easy.

Create six custom headphone mixes

With the LiveTrak L20R, you don't need separate personal monitor mixers — the monitoring is built in. Each of its six discrete monitor outputs provides a custom mix, so each member of your band can create and save their own. The L20R's headphone amplifier delivers lots of volume — even drummers won't have a difficult time hearing.

More than a mere digital mixer

The Zoom LiveTrak L20R is equipped with several operation modes. Put it in Audio Interface mode and the L20R transforms into a 22-in/4-out USB interface for your Mac, PC, or iOS device with flexible routing options. In USB Host mode, you can transfer projects and files to a connected USB flash drive. Card Reader mode allows you to transfer files to and from your computer.

Take command from your iPad

The LiveTrak L20R enables the FOH engineer and six musicians to take command of their own mix via the Remote Mixer app for iPad. With simple gestures, you can adjust fader levels, EQ settings, channel effects, and more — from anywhere in the venue.

Zoom LiveTrak L20R Features:

  • 20-channel rackmount digital mixer (16 mono/2 stereo)
  • 22-in/4-out USB audio interface for your Mac, PC, or iOS device (Apple Lightning-to-USB Camera Adapter is required for iOS)

Extremely limited, but has a role

I currently use the A&H Qu-PAC in a monitor mixing rig and have also used the Qu-SB. Though I like the Qu-PAC, I've wanted something lighter and more streamlined, as my split/monitor rack is presently 66 lbs. The A&H units are far more capable than the Zoom L20R. However, the price increases on those units over the past few years have left a nice market opportunity for Zoom in the sub-$1000 range. The L20R embodies the "minimum viable product" concept and you save a lot because of it.

Key L20R limitations vs. the Qu-PAC:

- Channel gains can not be remotely controlled. If you want to make an adjustment that affects all mixes (main and six monitor mixes) at the same time, you need to use the physical knob for that channel. You can not do it from the iPad. This is an issue if your band members don't provide consistent levels show-to-show and a player is also the main monitor mix person. Someone will need to adjust the physical gain knob, or, -every- player will need to adjust their mix separately to deal with the guitarist who can't leave his knobs alone between shows.
- No mix control from the front panel. It takes some button pressing on the A&H Qu-PAC, but in a pinch (e.g., dead iPad), you could do it.
- iPad control ONLY. A&H provides the Qu-YOU app for iPhone, iPad, and Android, allowing low-cost control with cheap tablets.
- No subgroups or effects on groups. Forget compressing background vocals together, for instance.
- No scene naming
- No separate talkback channel
- Monitor mixes are not really independent. Pans are global with the master mix. (I reverse stereo pans in Qu-PAC monitor mixes, for instance, since I am facing the opposite direction of the audience.)
- No digital snake expandability
- No auto mic mixing (AMM)


Neutral vs. the Qu-PAC:

- Using Bluetooth makes some sense and avoids the need for adding a router to the Qu series, which requires players to switch WiFi networks and lose Internet, depending on the scenario, but Bluetooth range might be a problem for mixing from the audience? (Note that only one iPad connects to the mixer via Bluetooth in "Hub Mode" and six others can then connect to that "hub" iPad in "Remote mode," the latter having access only to the A-F monitor mixes, not the main mix.)
- Rear panel hookups, which I prefer to the front panel connections of the Qu-SB and some other rack units.
- Still uses 4U racked despite being lighter and smaller.
- TRS monitor outs vs. Qu-PAC's XLR. This can be adapted easily enough.


Positives vs. the Qu-PAC:

- much lighter
- much cheaper
- no need to add a router
- recording to SD card vs. external drive (Qu-PAC is very unreliable with most USB sticks)
- Easy switching from mono-balanced to stereo-unbalanced monitor mixes. This is quite slick and removes the need for custom adapters I had to build to deal with dual-XLR stereo monitor mixes on the Qu-PAC.

Negative that is universal to all of these mixers:
- No built-in splits. Since these are often used for monitor mixing, but signals may also need to go to the house, the lack of split outputs means you need to add external splitters and a lot of cables if you want this to be your monitor rig and venues large and small. That's a lot of space and weight that could be handled far, far more efficiently inside the mixer itself.

Again, overall, I'd categorize the L20R as a "minimum viable product." It doesn't do much, but what it does just might be enough, and if so, it's a really slick product. For casual shows in small venues, I think it'd be fine. If you need to mix a more professional show, though, most sound people would feel quite constrained. The mixer would probably need to be on stage, making gain and channel-specific compressor adjustment awkward, and the lack of gates, compressors, etc. would make it hard to mix like a pro.

However, if you are just splitting signals to the L-20R and to the house, with the L-20R just doing monitor mixes… I think it does just, just enough.

I am still not sure it'll be a long term solution, but kudos to Zoom for making this thing.

The best for quick set ups

This little mixer is great for a band that uses the same settings every time. We have them saved in and we can just set up, plug in, and do a quick double check of our sound with little tweaks. Big sweeping changes on each sound check are a thing of the past. Plus, the recording feature is great for cutting a live album. Each channel records its own track at high quality.

A great little mixer!

I'm _NOT_ a sound engineer by any stretch of the imagination, so take that for what it's worth to start with. What I needed was a relatively quiet, versatile mixer with several monitor outputs which I could control remotely. This fits the bill perfectly for me. The downside being you can't really patch in outboard effects, which probably does limit its utility for some front of house situations, but for a practice PA it's perfect. The onboard recording feature is a nice bonus as well - I haven't used it much thus far, so I can't really say much about it, but if a Luddite such as myself can get it to work, it's probably fairly intuitive for most people!

Very compact 20 channel mixer and recorder

The L20-R is a fairly unusual device. It is small, light weight and relies on an iPad to manage almost all traditional mixer controls.

It includes 16 mic/line inputs and 4 line inputs with extremely quiet preamplifiers. You can use it to drive a 20 channel live sound mix and eq. while it can also record all channels independently to an SD card in 44, 48 and 96K sampling rates in 16 or 24 bit resolution.

The I20-R requires an iPad so frankly if you don't have or want an iPad, this is not your best choice.

The good news is the L20-R software is intuitive to use and the bluetooth link allows you to set the mix at various locations. That said, it does not have the range of WiFi so you can get about 40 feet from the mixer but no further. For me being able to record without a DAW is extremely valuable for rehearsal analysis and for capturing live performances. In addition to the main outputs it has 6 monitor outs that can be controlled by each players iPad, if they have individual iPads to balance their monitor's instrument level with the overall mix; a nice plus. One iPad can also set all of these to the individual musician's preference.

This recorder sounds very good and can produce excellent results. I recommend it where the space and and need for a traditional mixer layout is not needed. Remember you must have an iPad to go with this unit and it requires OS 13 or higher to operate.

exactly what I needed

I'm not a professional level musician. But, the L20R does exactly what I bought it for, especially the six separate monitor mixes. (The individual monitoring systems I was pricing were magnitudes more expensive.)

For our trio, I mic'd the drums with a pair of condenser mics, put the bass straight in, ran my stereo Digitech modeling pedal in for the guitar feed and put the L20R output into a Crown PA. No hum or noise, plus complete control over the mix. I muted the drums (wanted to record them, but not put them through the PA -- yes, this works). To our ears, playback of the recording sounded just like the performance we just played. And, it's very convenient to just click "record" and record the session.

WARNING: CANNOT BE USED WITHOUT iPAD APP!

I also have a TASCAM Model 24. By comparison, the Zoom is compact, super-lightweight, rack mountable and features the six separate monitor-out mixes (which can be run stereo or mono). Using the iPad App is extremely convenient because the mix can be managed remotely from the mixer; and multiple iPads can connect so musicians can control their individual monitor mixes. (Just don't lose the iPad or the bluetooth dongle -- don't know why it's a removable dongle and not "built in"!) Make sure to download the user manual, there are some non-intuitive things you will need to know, such as how to get your computer to play back through the L20R.

I use Audacity on Linux. Linux is not officially supported, but it recognized the L20R with no problem. Normally, I record straight to computer when using the TASCAM, although it can record to flash drive. With the L20R, it's pretty convenient to just record direct to flash drive and later retrieve the WAV files and import them into Audacity.

I gave Zoom and Sweetwater a hard time immediately after purchasing, as Zoom had not released an iOS 13 update to their App. So, the new iPad I bought expressly for the L20R wouldn't work and for awhile the device was simply a brick. I had to track down an iPad that would not update to 13 so I could use the iOS 12.X app. But, it works now with both iPads (I'm not sure why Sweetwater says it won't work with iPadOS 13, I *think* that is what is running on my new iPad).
