FRONT PANEL DESCRIPTION
1. POWER “ON” indicator: This yellow LED illuminates anytime the MP 24 is connected to an appropriate power source
(see #28, Rear Panel).
2. SOURCE CONTROL selectors: These four position rotary switches provide Input selection between the various Phono
and Line Inputs for their respective mixing Channels.
3. Input channel faders: These faders control the relative Levels of each of the four Input mixing Channels.
4. Channel CUE selectors: Engaging any single or combination of CUE pushbuttons sends any program present at the
respective Channel’s SOURCE CONTROL selector to the Headphone Cue section. The yellow LEDs adjacent to each CUE
select button illuminate when the switch is engaged.
5. CROSSFADE ENGAGE switch: Engaging this switch activates the CROSSFADER and disables manual mixing capabili-
ties. The adjacent green LED illuminates whenever the Crossfader is active.
6. Left-hand CROSSFADE ASSIGN switch: This four position rotary switch ASSIGNS the left side of the Crossfader to any
of the four Input Channels when the Crossfader is activated by its ENGAGE switch.
7. Right-hand CROSSFADE ASSIGN switch: This four position rotary switch ASSIGNS the right side of the Crossfader to
any of the four Input Channels when the Crossfader is activated by the ENGAGE switch.
8. CROSSFADER: This fader controls the Levels of any two Channels assigned to it by the left and right Crossfade ASSIGN
switches when the ENGAGE switch is activated. The entire Crossfader assembly is replaceable from the front panel
without disassembling the entire unit. See SERVICE INFORMATION on page Schematic-1for instructions.
9. ENGAGE MIC switch: This pushbutton enables the Microphone Inputs to feed the Booth, Zone, and Main Outputs. The
adjacent red LED flashes whenever the ENGAGE MIC switch is down and locked. This switch also activates a “ducker”
circuit in the Booth Output.(See #15 Front Panel and #20 Rear Panel.)
10. MAIN MIC LEVEL control: This rotary control sets the Level of the balanced low impedance MAIN MIC Input.
11. AUX MIC LEVEL control: This rotary control sets the Level of the unbalanced high impedance AUX MIC Input, most
often used for wireless mics.
