The MIC inputs feature +48V phantom power, allowing you to use condenser microphones. XLR Connector pin-out - Pin 1: Ground, Pin 2: Hot (+), Pin 3: Cold (-) 2.
Top Panel Controls 7. FX Auxiliary Control (MXP124FX) - The channel’s FX knob controls the amount of signal that is sent to the effects bus. The signal of the FX bus in the MXP124FX is routed to the Digital Effects section for on-board signal processing. The FX signal can also be sent to an external effect device connected to the FX SEND jack located on the front panel jack field. MON Auxiliary Control (MXP124) - Controls the amount of that channel’s signal that is sent to the MON Output.
Top Panel Controls Stereo Input Channel Section The following section details four stacked stereo input channels. 11. Stereo ¼” Input Jacks - Use the ¼” jacks for connecting stereo line level sources. For stereo inputs use the LINE L to connect the left channel and the LINE R to connect the right 11 channel. 11 Use the LEFT input when connecting a mono input signal to the Stereo Input channels. You can connect outputs from high impedance microphones, synthesizers and drum machines to these inputs.
Top Panel Controls Digital Effects Section (MXP124FX only) The following section describes the features control of the onboard 24-bit digital Multi-effects section. 16.
