Unscrew the FADER PLATE SCREWS (B). Do not touch the INSIDE SCREWS (C). Carefully lift the fader and unplug the CABLE (D). Plug the new fader into CABLE (D) and place it back in the mixer. Screw the fader to the mixer with the FADER PLATE SCREWS (B).
USING THE GROUND LIFT SWITCH:
Depending on your system configuration, application of the ground will sometimes create a quieter signal path. Lifting the ground occasionally eliminates ground loops and hum to create a quieter signal.
8. EQUALIZER: This unit features dual 7 band GRAPHIC EQUALIZERS (36, 37) that allow you to adjust the sound to fit any room. Activate the equalizer by pressing EQ BUTTON (38) (EQ LED is illuminated). By adjusting any of the 7 LEFT (36) equalizer slide controls, you can cut or boost the tonal characteristics of the sound coming from the LEFT speaker by 12 dB. Adjusting any of the 7 RIGHT (37) equalizer slide controls allows you to cut or boost the tonal characteristics of the sound coming from the RIGHT speaker by 12 dB. Deactivate the equalizer by pressing the EQ BUTTON (38) again (EQ LED is OFF). 9. OUTPUT CONTROL: The level of the AMP OUTPUT (5) is controlled by the MASTER (39) slide. Activating the MONO (40) button (MONO LED is illuminated) converts the overall output to mono. The BOOTH (41) control adjusts the level of the BOOTH OUTPUT (6).
1. With the mixer ON, listen to the system in idle mode (no signal present) and with the ground applied and the GROUND LIFT SWITCH (24) in the LEFT position.
HINT: BOOTH OUTPUT IS USED BY SOME DJS TO RUN MONITOR SPEAKERS IN THE DJ BOOTH. IT IS ALSO USED AS A SECOND ZONE OR AMP OUTPUT. NOTE: REC OUTPUT HAS NO LEVEL CONTROL. LEVEL IS CONTROLLED WITH THE CHANNEL SLIDES OF THE SELECTED CHANNEL(S). TONE IS CONTROLLED BY THE EQUALIZERS.
10.TALKOVER: The purpose of the talkover is to allow the program playing to be muted so that the MIC may be heard above the music. The MIC/ TALKOVER SWITCH (42) controls MIC 1 and MIC 2 and has 3 settings: When MIC/TALKOVER (42) is in the BOTTOM position, MIC 1, MIC 2 and TALKOVER are all OFF. When MIC/TALKOVER (42) is in the CENTER position, MIC 1 and MIC 2 are ON. MIC INDICATOR (43) glows when TALKOVER is OFF. When MIC/TALKOVER SWITCH (42) is in the TOP position, MIC 1, MIC 2 and TALKOVER are ON and the volume of all sources except MIC inputs is lowered by 16 dB. 11.TREBLE (46) and BASS (47) controls allow you to adjust the tone of MIC 1 and MIC 2. MIC 1 LEVEL (44) controls the level of MIC 1 while MIC 2 LEVEL (45) controls the level of MIC 2. 12.CUE: By connecting a set of headphones to the HEADPHONE (22) jack, you can monitor any or all channels. Press CUE ASSIGN (48) buttons for Channels 1 through 4 and select the Channel(s) to be monitored. The respective LED indicators will glow. Use the CUE LEVEL (49) control to adjust the cue volume without changing the overall mix. By moving the CUE PGM PAN (50) control to the LEFT you will be able to monitor the assigned cue signal. Moving the control to the RIGHT allows you to monitor PGM (program) output. 13.DISPLAY: The DISPLAY (51) indicates the MASTER output of the left and right levels.

3. Tapping the START/STOP (55) button with the MODE SELECTOR (53) switch in the SINGLE position causes sampler to play back one time (the SAMPLER INDICATOR will glow GREEN). Each push of the START/ STOP (55) button restarts the sample from the beginning. Rapid pressing of the START/STOP (55) button will cause a stuttering effect. Once the sample has started playback and the START/STOP (55) button is not pushed a second time, the sample will play to the end and stop. 4. Tapping the START/STOP (55) button with the MODE SELECTOR (53) switch in the REPEAT position causes the sample to play continuously. The START/STOP (55) button acts an ON/OFF switch. The first push starts the sample, the second push stops it. The SAMPLER LEVEL (56) controls the level of the sample. Press the SAMPLER CUE (57) to hear the sample that is being CUED up.

ROBO PLAY:

1. With the ROBO PLAY (58) button OFF and the MODE SELECTOR (53) switch in either the SINGLE or REPEAT mode, pressing the START/ STOP (55) button will cause the sample to play along with the selected source. 2. When the ROBO PLAY (58) button is in the ON position starting the sampler mutes the selected source. When the sample ends, the source automatically turns back on.

BATTERY BACKUP:

BATTERY BACKUP: The PMX-2400 is equipped with battery backup to retain samples. To activate this feature, a 9 volt battery (not included) should be connected to the BATTERY HOLDER (59) located on the rear panel. This enables the storage of samples in memory. When the unit is unplugged, the battery backup retains the samples for future use.
NOTE: IF THE UNIT IS UNPLUGGED WITH NO BATTERY ATTACHED, ALL SAMPLES WILL BE LOST.

PMX-1800 ONLY:

1. ECHO SECTION: Echo can be applied by pressing the ECHO (52) button (the LED will light). You can adjust the LEVEL (53), REPEAT (54) and DELAY (55) parameters of the echo by using the ECHO controls. To turn the echo off, push the ECHO (52) button again (the LED will turn off). 2. SOUND EFFECTS SECTION: Six different sound effects (UFO, TRON BLAST, SIREN, GAS, MACHINE GUN & EMERGENCY) may be added to your mix by depressing the SOUND EFFECTS CONTROL BUTTONS (56). The volume of the effects can be adjusted using the EFFECTS LEVEL CONTROL (57). The pitch of the effects can be increased or decreased using the EFFECTS SPEED CONTROL (58).
LOW BATTERY INDICATOR: A low battery indicator is included with the PMX-2400. When changing the battery, make sure the unit is plugged in and the power is ON. Failure to adhere to this will result in lost memory and vanished samples. The low battery indicator is ON when the selected memory bank LED blinks. The LED blinks a warning if no battery is connected to the unit.

PMX-2400 ONLY:

SAMPLER OPERATION:

GENERAL INFORMATION: The PMX-2400s Sampler uses Dynamic RAM memory and a 12 bit microprocessor controller. This full bandwidth results in true sound reproduction. MEMORY INFORMATION: The PMX-2400 is equipped with five MEMORY BANKS (52). The two banks marked 2 & 2 are two seconds in length, the two banks marked 4 & 4 are four seconds in length and the bank marked 12 is twelve seconds in length. These banks are separate and CAN NOT be linked. You can store a different sample in each bank, but they must be recorded individually and must be played one at a time. 1. Put the MODE SELECTOR (53) switch into the WRITE position. 2. Select the sample source by pressing the appropriate CUE/SAMPLE (48) assign button(s). 3. Select the record to memory bank by pressing the proper MEMORY BANK (52) button. 4. The PMX-2400 comes equipped with a sampler PITCH (54) control. To get a perfect sample, set the control to its center position and record the sample. Raising or lowering the control during playback raises or lowers the pitch of the sample. The center position retains the normal pitch.
HINT: YOU CAN RECORD A SAMPLE WITH THE PITCH CONTROL IN ANY POSITION. WHATEVER THAT POSITION IS WILL BECOME NORMAL SOUND. IF YOU START TO RECORD A SAMPLE WITH THE PITCH CONTROL SET AT MINIMUM THAT WILL BECOME YOUR NORMAL PITCH. BY INCREASING THE PITCH TO MAXIMUM DURING PLAYBACK, THE PITCH EFFECT WILL DOUBLE IN SPEED. RECORDING AT MAXIMUM AND LOWERING TO MINIMUM DURING PLAYBACK WILL DO EXACTLY THE OPPOSITE.

SAMPLE RECORDING:

5. Tapping the START/STOP (55) button begins the sampling process (the SAMPLER INDICATOR will glow RED). Tapping the START/STOP (55) button a second time ends the sample (the SAMPLER INDICATOR will turn off). If you do not tap the START/STOP (55) button a second time, the sampling process stops automatically after 2, 4 or 12 seconds depending on which MEMORY BANK (52) was selected. 1. Set the MODE SELECTOR (53) switch to SINGLE or REPEAT. 2. Select the desired memory bank by pressing the proper MEMORY BANK (52) button.
