Detailed Description MG12XU
MG12XU is a Yamaha MG 12-channel analog mixer with 6 microphone inputs, stereo source connections and built-in SPX effects. Linear faders provide channel and master-level control. The available mono, mono/stereo and stereo channels are itemized in the specifications.
D-PRE microphone preamps, phantom power and channel EQ support microphone and line-level sources. One-knob compression is provided on selected channels, while auxiliary and monitoring connections support the model’s routing options. Balanced main outputs and headphone monitoring connect the mixer to a sound system or local listening setup.
The two-input / two-output USB interface supports 24-bit audio at sample rates up to 192 kHz. It transfers a stereo mix rather than recording every input independently. Typical applications include rehearsals, small performances, speech and compact recording systems. Use the model-specific input, output and level tables when choosing cables and connected equipment.
