Main Features D-PRE and High-Quality Operational Amplifiers Mono input channels are equipped with “D-PRE” Class-A discrete microphone preamplifiers. The D-PRE head amplifier features an inverted Darlington circuit used in high-end audio devices. This circuit uses multi-stage amplifying elements to ensure high current and low impedance, for an audio texture with crispness and richness in the low and mid frequencies.
Quick Start Guide We’ll begin this guide by connecting a pair of speakers and generating some stereo output.

Troubleshooting When No Sound Is Output Refer to this section when no sound is output or the volume is very low. This information is for when sound is output from the [STEREO OUT] jacks or the [PHONES] jack. For details about these functions, see “Controls and Connectors” on pages 14 – 28. STEP 1 Connections and Signal Flow Check if the instruments, microphones, and speakers are connected correctly, and if any of the cables are damaged. When connecting guitars or basses to the MG, use DI boxes.
Troubleshooting STEP 2 Setting Switches and Controls Check the overall balance Use the settings shown in the illustration to check the overall balance from speakers or headphones. [GAIN] knobs Turn until the [PEAK] indicator begins to flash intermittently. [PHANTOM +48V] switch Turn this switch on (the indicator lit) when using a condenser microphone. • To prevent an unwanted burst of noise from the speakers, turn off powered speakers (or power amps) before turning on the [PHANTOM +48V] switch.
Troubleshooting Other The power does not come on. Is the mixer connected to an independent power source (generator, etc.) or a power strip with switches? Check that the power of that device is turned on. No sound is output.

Appendix Mounting Procedures Rack Mounting The MG12XU/MG12 require at least 10 U* of rack space. To take into account the cable connections, we recommend to ensure 11 U* of rack space. The MG20XU/MG20/MG16XU/MG16 require at least 12 U* of rack space. To take into account the cable connections, we recommend to ensure 14 U* of rack space. (The illustration shows the MG12XU.) 1. Use a screwdriver to loosen the screws on the sides of the mixer (six total).
