The yellow LEDs adjacent to each CUE select button illuminate when the switch is engaged. 5 CROSSFADE ENGAGE switch: Activates the CROSSFADER and disables manual mixing capabilities. The adjacent green LED illuminates whenever the Crossfader is active. 6 Left-hand CROSSFADE ASSIGN 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: Assigns the right side of the Crossfader to any of the four Input channels when the Crossfader is activated by the ENGAGE switch. 8 ACTIVE CROSSFADER: 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 Manual-9.) 9 ENGAGE MIC switch: 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.(SeeFront Panel t and Rear Panel p.) 0 MAIN MIC LEVEL control: Sets the Level of the balanced low impedance MAIN MIC Input. q AUX MIC LEVEL control: Sets the Level of the unbalanced high impedance AUX MIC Input, often used for wireless mics. w Microphone equalization controls: Adjust the frequency contour of both Microphone Inputs. They have no effect on any other program material. Manual- e LOOP ENGAGE switch: Controls the Switchable Effects Loop; pressing it to its down and locked position routes the main signal through the processor attached to the SWITCHABLE LOOP connectors on the rear. (See Rear Panel w and e.) r MASTER LEVEL fader: Determines the program and mic level at the Main Outputs. Unity gain is approximately "4.5". t BOOTH LEVEL control: Adjusts the program and mic level at the Booth Outputs. Unity gain is approximately "6.5". This Output utilizes a "ducking" circuit, reducing the mic level when the MIC ENGAGE switch is pressed. (See Rear Panel p.) y ZONE LEVEL control: Adjusts the program and mic level of the Zone Outputs. Unity gain is approximately "6.5". u PROGRAM EQUALIZER controls: Contour the frequency response of the program at the Main, Booth and Zone Outputs. This is not designed to be the only equalizer in the system, this is intended to provide EQ between varying program materials. i PROGRAM EQUALIZER ENGAGE switch: Enables the Program Equalizer to function when pressed in. The Equalizer is bypassed in the out position. o HEADPHONE LEVEL CONTROL: Clockwise rotation of this rotary control increases the headphone drive level. p HEADPHONE PAN CONTROL: Serves two purposes...In the STEREO mode it changes the relative levels of the Cue and Program mixed together in both earcups. In the MONO mode it changes the balance between the Mono Cue in the left ear cup and the Mono Program in the right. a HEADPHONE CUE mode switch: In the up position, this switch feeds STEREO Program and Cue to both earcups, in the down position the Headphone circuit provides MONO Cue to the left ear and MONO Program to the right. s HEADPHONE output jack: A tip-ring-sleeve stereo jack provides for the insertion of stereo headphones. d PEAK PROGRAM METER: provides a visual indication of program output voltage. The calibration of the indication is user adjustable. (See Rear Panel 6.) Fader Cleaning With heavy use in harsh environments, the faders may need lubrication. This treatment extends longevity and can make used faders as good as new. The fader assembly must be removed from the MP 24z for proper cleaning. We recommend any of the following cleaning solutions: Caig DeoxIT FaderLube F100 spray lubricant (www.caig.com) Caig DeoxIT FaderLube F5 spray cleaner (www.caig.com) CRC 2-26 (www.crcindustries.com) Order CaiLube MCL® from: CAIG Laboratories, Inc. 12200 Thatcher Ct. Poway, CA 92064 Phone 858-486-8388 Fax 858-486-8398 www.caig.com CLEANING INSTRUCTIONS A. Fader assembly removal 1. Remove (2) 3mm screws. 2. Draw fader assembly out through hole. 3. Remove ribbon cable. B. Fader cleaning 1. Hold the fader assembly away from the mixer. 2. Position the fader at mid-travel. 3. Spray cleaner/lubricant into both ends of the fader. 4. Move the fader over its full travel back and forth a few times. 5. Shake excess fluid from the fader assembly. 6. Wipe off excess fluid.

Pin 3 must never be grounded for unbalanced operation. Use only pin 2 as hot and pin 1 as return for any unbalanced operation. 2 UNBALANCED MAIN OUTPUT connectors: Provide Main Output signals on ¼" TS (tip-sleeve) unbalanced connections. 3 BOOTH OUTPUT connectors: The Left Output only supplies a mono Booth Monitor Output; connecting to both Left and Right provides a stereo Output. 4 ZONE OUTPUT connectors: The Left Output only supplies a mono Zone Output, connecting to both Left and Right provides a stereo Output. The Zone Outputs are located Post-EQ, which includes the Microphone Output. An internal jumper block programs the Zone to Pre-EQ (and no mic) if required. (See Service Information on page Manual-9.) 5 MAXIMUM OUTPUT GAIN REDUCTION control: Decreases the maximum Level of the balanced and unbalanced MAIN OUTPUTS of the MP 24z as it is rotated counter-clockwise. 6 METER SENSITIVITY ADJUST: Clockwise rotation decreases the full-scale sensitivity of the PEAK PROGRAM METER, as indicated by the full-scale voltage calibrations around the control. 7 SYSTEM MONO/STEREO switch: Engaging this pushbutton converts all Outputs (except tapes and loops) to MONO, regardless of the nature of the Input signals. 8 EQ RANGE switch: In the out position, the maximum boost/cut available from the Program Equalizer is ±8 dB. In the switch's in position, this range is reduced to ±4 dB. 9 LIGHT CONTROL OUTPUT jack: Provides a transformer-coupled mono program signal for use by a lighting controller's trigger input. This is a balanced ¼" output--the tip is positive, the ring is negative and the sleeve is floating. 0 LIGHT OUTPUT LEVEL attenuator: Counter-clockwise rotation reduces the Output Level at the LIGHT CONTROL OUTPUT jack. Manual- q TAPE OUT jacks: One pair of RCA jacks provides pre-EQ, pre-LOOP Program Outputs. The other pair supplies pre-EQ, postLOOP Program Outputs. The microphone signals are not available at these Outputs, however they are selectable using an internal jumper block. (See Service Information on page Manual-9.) w SWITCHABLE LOOP SEND jacks: Use these ¼" unbalanced Left and Right Outputs for driving the inputs of a processor activated by the LOOP button (front panel e). e SWITCHABLE LOOP RETURN jacks: Use these ¼" unbalanced Inputs for receiving the outputs of the above processor. r MAIN EFFECTS LOOP SEND jacks: Provide drive to the inputs of a signal processor which is not to be switched from the front of the mixer. Connecting only to the LEFT Effects Send provides a mono Output; connecting to both LEFT and RIGHT provides a stereo feed. These are ¼" TS (Tip-Sleeve) unbalanced connections. t MAIN EFFECTS LOOP RETURN jacks: Receiving the processed signal generated from the Main Effects Loop SENDs. These are ¼" TS unbalanced connections. y Balanced MAIN MIC Input jack: Connects a balanced microphone of any impedance, either dynamic or condenser. u Unbalanced high-impedance AUX MIC Input jack: Connects an unbalanced wireless or other high-impedance mic. i MIC LOOP jack: Inserts external signal processing in the microphone circuit only. This is a ¼" TRS tip-send, ring-return configuration. This feature does not affect the operation of the Main Program channels. o PHANTOM POWER switch: Engaging this pushbutton applies +15 V Phantom Power to the balanced (XLR) MAIN MIC Input only. It has no effect on the Aux Mic Input. The adjacent red LED illuminates whenever Phantom Power is active. p BOOTH DUCKER switch: When in the ACTIVE position, the ENGAGE MIC switch (front panel 9) reduces the Microphone level at th ...
