Connections
1. Before plugging in the power cord in the outlet (230 V/ 50 Hz), make sure that the POWER (1) switch is in the
off position. The POWER LED (2) will be off.
2. The MX 660 is supplied with 3 sets of output jacks. The AMP jacks (20) are used to connect to your main amplifier.
The REC jack (22) can be used to connect the mixer to the record input of your recorder enabling you to record
your mix. The output BOOTH jacks (21) allow you to hook up an additional amplifier.
3. The DJ MIC (3) input found on the upper panel accepts a microphone with XLR connector. An additional MIC 2
(4) input accepting a microphone with 6, 35 mm connector is found on the front panel.
4. On the rear panel are stereo PH/LN or Phono/Line (23) inputs and 3 stereo inputs LN (24, 25, 26). The PH/LN
or Phono/Line switches (27) enable you to set the (23) inputs to Phono or Line. The phono input will accept only
turntables with a magnetic cartridge. A ground screw GND (28) for you to ground your turntables is located on
the rear panel. The stereo LN/Line inputs (23-26) will accept any devices such as a CD-/MD-Player, a cassette
player and/or a video player.
5. Headphones can be plugged into the upper panel mounted Phones (5) jack (6,35 mm).
Operation
1. Power on: Once you have made all the equipment connections to your mixer, press the POWER switch (1). The
power will turn on and the POWER LED (2) will glow RED.
2. Channel 1: The GAIN (6), TREBLE (7), MID (8) and BASS (9) controls allow you to fully adjust the selected
source. Switch (10) allows you to select either the PH1/LN1 (23) or the LINE 2 (24) input. The channel slide CH1
(11) controls the output level of this channel.
3. Channel 2: The GAIN (12), TREBLE (13), MID (14) and BASS (15) controls allow you to fully adjust the selected
source. Switch (16) allows you to select either the LN3 (25) or the LN4 (26) input. The channel slide CH2 (17)
controls the output level of this channel.
4. Crossfader: The CROSSFADER (18) allows the mixing of one source into another. The left side of the
CROSSFADER (18) is channel 1 and the right side is channel 2. The Crossfader (18) in your unit is removable
and if the need arises can be easely replaced. Just follow these instructions:
a) Unscrew the outside Fader Plate Screws (A). Do not touch the inside screws (B).
b) Carefully lift the fader (18) and unplug the cable.
c) Plug the new fader into the cable and place it back in the mixer.
d) Screw the new fader to the mixer.
5. Killing frequencies: There are two ways to kill frequencies, using the TREBLE, MID, BASS KILL switches (19,
20, 21) and using the TREBLE, MID, BASS (7, 8, 9) rotary controls for channel 1 and (13, 14, 15) for channel 2.
When the selected kill switch is activated the LED will light and the frequency will be killed. You can also use the
rotary controls to boost frequencies up to + 10 dB. The normal setting for the rotary controls is zero.
Suggestion: You can use the Kill Features on each channel to remove Bass, Mid and High bands for a smoother
mix and mix frequencies from both channels to create special effects.
6. Punch in: The PUNCH IN button (29) allows you to add a channel’s signal to the mix when the crossfader is set
to that channel.
7. Output control section: the level of the AMP (20) ist controlled by the MASTER (23) control. The BOOTH (32)
control adjusts the level of the BOOTH OUTPUT (21). The booth output is used by some DJs to run monitor
speakers in their DJ booth. You can also use it as a second AMP output.
Note: the REC out (22) has no level control. The level is set by the channel slides.
8. Talkover section: The purpose of the talkover section is to allow the program playing to be muted so that the mic
can be heard above the music. The OFF ON TALKOVER switch (33) has 3 settings. When the switch (33) is in
the off position, the mic 2 and talkover are both off. When the switch is in the on position, the mic 2 will be on but
talkover is off. When the TALKOVER switch is in the righthand position, the mic 2 and talkover are on. The volume
