Yamaha MG12X 12-Channel Analog Mixer with SPX Effects
The Yamaha MG12X is a 12-channel analog mixing console that pairs the routing of the MG12 with Yamaha's SPX digital effects. It takes up to six microphones on D-PRE preamps, offers two group buses and two AUX sends, and gives you 24 reverb, delay and modulation programmes without any outboard gear.
It suits live bands, churches, schools, banquet halls and small venues that want a dependable fader desk with polished vocal effects built in. If you also need to record to a computer, the MG12XU is the same console with a USB audio interface added.
Key Features

Six D-PRE Mic Inputs on the MG12X
Channels 1-4 have balanced combo jacks, and channels 5/6 and 7/8 each add an XLR mic input alongside their line jacks, for up to six microphones. Every mic input runs through Yamaha's discrete Class-A D-PRE preamp with an inverted Darlington circuit, and a +48V switch powers condenser mics.
SPX Digital Effects with 24 Programmes
The built-in SPX processor offers 24 programmes, including halls, rooms, plate, delays, vocal echo, chorus, flanger and pitch change. Pick a programme, fine-tune it with the PARAMETER knob, and add an optional FC5 foot switch to turn the effect on and off between songs.
Group Buses and AUX Sends for Live Mixing
Two group buses let you sub-mix drums or backing vocals onto one fader or feed a separate zone from the GROUP OUT jacks. AUX 1 and AUX 2 have PRE switches for pre- or post-fader sends, and AUX 2 doubles as the effects send, so the MG12X can run a monitor mix and effects together.
1-Knob Compressors and Three-Band EQ
Yamaha's 1-knob compressor sets threshold, ratio and gain in one control for steadier vocals and instruments. A three-band EQ with 10 kHz and 100 Hz shelving and a 2.5 kHz mid (all +/-15 dB), plus an 80 Hz high-pass filter and 26 dB pad on the mono channels, keeps each source clean.
Faders, PFL and Clear Metering
Channel faders, a GROUP 1-2 fader, an FX RTN fader and a STEREO master make level changes quick during a show. PFL switches let you check any channel in headphones, and a 2 x 12-segment LED meter shows the output level.

Internal Power Supply on the MG12X Mixer
A built-in universal power supply runs on 100-240 V mains with a standard AC cord, so there is no external adaptor to lose. The powder-coated metal chassis weighs 4.2 kg, and the optional RK-MG12 kit turns it into a rack-mount console.
Frequently Asked Questions
What is the difference between the MG12X and the MG12XU?
The MG12XU adds a 24-bit/192 kHz USB audio interface and a Cubase AI download. Inputs, preamps, effects, groups, AUX sends and chassis are the same, so choose the MG12X if you will not record or play back from a computer.
How is the MG12X different from the MG12?
The MG12 has the same channels, groups and AUX sends but no effects. The MG12X adds the SPX processor with 24 programmes, an FX return fader and a foot-switch jack.
Does using the effects take up an AUX send?
Yes. AUX 2 also feeds the internal effects, so you typically use AUX 1 for a monitor mix and AUX 2 for effects. The MG16X has four AUX sends if you need more mixes.
What comes in the box?
Yamaha lists the AC power cord, Owner's Manual and Technical Specifications sheet. The RK-MG12 rack-mount kit and FC5 foot switch are optional extras.
Who is the MG12X best suited to?
Small bands, churches, schools, conference halls and event setups that need up to six mics, a couple of monitor or zone feeds and built-in reverb on a compact fader console.
