Audio Mixer (16 Mic/4 Stereo/USB) Yamaha MG20xu

Hire Yamaha MG20XU Analogue Mixer

20 Channel Mixing Console with USB Recording and SPX Effects

The Yamaha MG20XU is Edwards NZ's go-to analogue mixer for events and productions where a straightforward, high-quality mixing console is needed without the complexity of a digital desk. Twenty input channels, sixteen discrete D-PRE microphone preamps, built-in SPX digital effects, one-knob compression on the first eight channels, and a USB audio interface for direct computer recording — all in a rugged metal chassis with rack-mount brackets included. Hire code MX20Y.

Yamaha's D-PRE preamps use an inverted Darlington circuit — a discrete Class-A design that delivers low noise, low distortion, and a natural, musical sound character that analogue mixing engineers trust. These are not budget preamps in an entry-level chassis — the MG20XU is a professional-grade console that Yamaha designed for live sound, broadcast, installation, and studio use. The sound quality at the preamp stage is the reason this console remains a reliable choice for events where audio quality matters and operational simplicity is equally important.

One-knob compressors on channels 1 to 8 add professional dynamic control without requiring a trained operator to understand compression ratios and attack times — turn the knob clockwise to apply more compression, leave it off for a transparent signal path. The SPX effects processor provides 24 programmes of reverb, delay, chorus, and modulation effects with straightforward parameter control. Three-band EQ with sweepable midrange on the mono channels gives enough tonal shaping for most live sound applications without the complexity of a fully parametric system.

The USB interface records directly to a connected computer at up to 24-bit/192kHz — significantly higher resolution than most digital consoles' USB recording capability. For events where a recording of proceedings is needed, the MG20XU connects to any computer via USB and appears as a class-compliant audio interface without driver installation on most systems.

Frequently Asked Questions — Yamaha MG20XU Analogue Mixer Hire

How many microphones can I connect?

The MG20XU has 16 XLR microphone inputs across 12 mono combo channels and 4 stereo channels, all with the D-PRE preamps. Phantom power at 48V is switchable for condenser microphones. The 4 stereo channels also accept line-level sources via TRS inputs, making them ideal for keyboards, laptops, media players, and other line-level sources alongside the microphone channels.

Is this easier to operate than a digital mixer?

For most users, yes. Analogue consoles have no layers, no menus, and no modes — every control is visible and does exactly what it says. If you can see the gain knob for a channel, that knob only ever controls gain for that channel. There is nothing hidden. For operators who are not regular sound engineers, an analogue console like the MG20XU removes the learning curve of digital desk operation entirely. The one-knob compressors on channels 1 to 8 extend this simplicity to dynamics control — a single knob handles what would otherwise require understanding of threshold, ratio, attack, and release.

What are D-PRE preamps?

D-PRE stands for Discrete PRE-amp — Yamaha's Class-A microphone preamp design using an inverted Darlington transistor circuit. Discrete Class-A preamps operate each transistor independently rather than sharing components, which reduces distortion and noise and produces a cleaner, more natural sound than integrated circuit preamps commonly used in lower-cost equipment. The D-PRE is the same preamp technology Yamaha uses in their professional studio and broadcast consoles — it is one of the primary reasons the MG series is trusted for professional applications.

What effects does it have?

The built-in SPX effects processor provides 24 programmes covering reverb, delay, chorus, flanger, phaser, and combination effects. SPX is Yamaha's professional effects platform — the same technology found in their standalone SPX hardware effects units used in professional touring and broadcast. The effects are applied to a dedicated effects send and return, keeping them separate from the main signal path. For most live events reverb on vocal microphones and delay for performances are the most commonly used programmes.

Can I record directly from this mixer?

Yes. The 2-in/2-out USB interface connects to any computer and captures the main stereo mix at up to 24-bit/192kHz resolution — higher than most digital consoles' USB recording capability. On macOS the interface is class-compliant and requires no driver installation. On Windows a driver may be required depending on the operating system version. The recording captures the main stereo mix post-fader, making it suitable for recording event proceedings, performances, or podcast content directly to a DAW or recording application.

What is the difference between this and the Soundcraft and A&H digital mixers?

The MG20XU is an analogue console — simpler to operate, no scenes or presets, no touchscreen, and no layering. What you see is what you get. The Soundcraft Expression 1 and Performer 2 are digital consoles with full recall, scene storage, built-in automation, and remote control via iPad — more capable for complex productions but with a steeper learning curve. For events where simplicity, reliability, and straightforward operation are the priority and the input count fits within 20 channels, the MG20XU is the right choice. For productions requiring scene recall, monitor mixing from the stage, or more than 20 inputs, a digital console is the better tool.

Does it have group outputs for zone control?

Yes — the MG20XU has 4 group buses in addition to the main stereo output. Groups allow multiple channels to be subgrouped to a single fader before the main mix — useful for routing a drum kit to one group fader, a choir to another, or separating speech microphones from music sources for independent level control. The 4 aux sends support foldback monitor mixes and effects sends simultaneously.

Is delivery and setup available?

Yes. The MG20XU is available for self-collection or delivery and setup by an Edwards technician. Contact our hire team at (09) 571 0551 or hire@edwardsnz.co.nz to discuss your event requirements.
