4) Input channel effects assign indication LED’s
These LED’s indicate which channel is routed trough one of the effects outputs. If the FX-1 and
FX-2 LED’s do not light up, no channel is routed via the effects. If the FX-1 LED of a channel
lights up green, that channel is routed via effects output 1. If the FX-1 LED of a channel lights
up red, one of the other channels is routed via FX-1 and no other channel can be routed via
FX-1 at that moment.
Same counts for the FX-2 LED that lights up. If the FX-1 LED is blinking red, the input channel
effects assign potentiometer (5) must be turned back to its center position because it was
initially placed in a fault position.
5) Input channel effects assign potentiometer
With this control, the input signal can be routed via effects output 1 or 2. When the knob is
placed in the center (12 o’clock) position, the signal goes straight to the main mix without
passing via one of the effects-outputs. When the knob is turned to the left, the signal will go via
the effects 1 output. When the knob is turned to the right, the signal will go via the effects 2
output. The proportion between the dry (no effect) and wet (100% effect) can be set with the
potentiometer.
6) Balance control
The balance between the amount of sound on the left and on the right is adjusted by using this
knob. When it is set to the center position, the gain is the same for both the left and the right
channel. When turned to the left, the right channel will decrease. When turned to the right, the
left signal will decrease.
7) Routing selector
With this selector the signal can be lead: to the left side of the crossfader (X), directly to the
output (MIX) or to the right side of the crossfader (Y).
8) PFL switches
With these switches you can select the different input sources that you will listen to with the
headphones.

depending on the position of the VU-2 signal select switch (27).
14) Crossfader
With this fader you can easily fade over between the channels with routing-selector (7) on X-
position and the channels with routing-selector (7) on Y-position. When the knob is turned
completely to the left, the signal of the channels with routing selector (7) on X will appear on the
output. When the knob is turned completely to the right, the signal of the channels with Routing
selector (7) on Y will appear on the output. In between there will be a mix of both signals.
15) DJ microphone fader
Volume control for DJ microphone
16) DJ microphone PFL switch
With this switch the microphone signal can be made audible in the headphones and made
visible on the left VU-meters.

22) Monitor mode Switch
This switch is used to set the monitor output in mono or stereo mode.
23) Master 1 and master 2 mode Switch
This switch is used to set the master 1 and 2 outputs in mono or stereo mode.
24) Record Select
This switch is used to make recordings with or without the DJ microphone.
+ DJ MIC: in this position you add the DJ mic signal to the music.
- DJ MIC: in this position you only record the signal from channel 1 - 4.
This switch has no influence on the master outputs.
25) Main mix effects assign indication LED’s
These LED’s indicate if the main mix signal is routed through one of the effects outputs. If the
FX-1 and FX-2 LED’s do not light up, the main mix signal is not routed via the effects. If the FX-
1 LED lights up green, the main mix signal is routed via effects output 1. If the FX-1 LED lights

11
up red, an input channel’s signal is routed via FX-1 output and no other channel can be routed
via FX-1 at that moment.
Same counts for the FX-2 LED that lights up. If the FX-1 LED is blinking red, the main mix
effects assign potentiometer (26) must be turned back to its center position because it was
initially placed in a fault position.
26) Main mix effects assign potentiometer
With this control, the main mix signal can be routed through effects output 1 or 2. When the
knob is placed in the center (12 o’clock) position, the signal goes straight to the main mix
without passing through one of the effects-outputs. When the knob is turned to the left, the
signal will go through the effects 1 output. When the knob is turned to the right, the signal will
go through the effects 2 output. The proportion between the dry (no effect) and wet (100%
effect) can be set with the potentiometer.
27) VU-2 signal select switch
With this switch is it possible to select the signal displayed on the two right VU-meters. When
the switch is on the SUM position the mix-signal will be displayed. On the positions MASTER 1,
MASTER 2 and MONITOR the according output signals will be displayed.
28) Alarm/music mute indicator LED
This LED indicates the amount of music suppression due to the control signal on the optional
alarm/music mute input. When the LED doesn’t light up, the music is not suppressed. When the
LED lights up at full power, the music is fully suppressed.
29) Headphones-select potentiometer
With this potentiometer, the signal for the headphones output can be selected. When turned
completely to the left, the signal selected with the channel PFL-switches (8) appears on the
headphones. When turned completely to the right, the mix-signal appears on the headphones.
In between it results in a mix of the PFL-signal and the mix-signal.
30) Headphones volume control
The volume of the headphones can be adjusted with this knob.
WARNING! The sound and intensity volume of the headphones amplifier can be very
strong and, if not used properly, or if used in too close proximity, can cause
permanent or temporary damage to one’s hearing, perhaps even deafness.
Please use with caution and common sense!
31) Phones output
Output for high level headphones monitoring. With the PFL switches (8 or 16) and the
headphones-select potentiometer (29), the connected audio sources or the main-mix can be
made audible without manipulating the output signal (Headphones 32-600Ω).
ATTENTION! Always turn headphones volume to “0” (fully counter clockwise) BEFORE
putting the headphones on your or somebody else her/his ears! Then
slowly raise the volume by turning the volume knob in clockwise direction.
32) Cross fader curve potentiometer
This potentiometer is used to set the sharpness of the cross fader. When the potentiometer is
turned completely to the left, the cross fader (14) will react as a normal cross fader. The
volumes of the channels with routing-selector (7) on Y-position will rise from 0 to maximum
when the shaft of the cross fader is moved from the left to the middle. The same counts for the
volumes of the channels with routing-selector (7) on X-position, but then from the right side to
the middle.

12
When the curve potentiometer is turned to the right, the cross fader will react very fast, with the
volumes of the channels with routing-selector (7) on Y-position rising from 0 to maximum when
the shaft of the cross fader is moved from the left to a few fractions from the left. The same
counts for the volumes of the channels with routing-selector (7) on X-position, but then from the
right side to a few fractions from the right side.

position to get the stereo signal on the headphones and the two left VU-meters. The PFL circuit
works as a sum-system, there is a possibility to listen to more sources at the same time. All
these operations have no influence on the output signal! Adjust with the level control (2) the
input signal until the red indicators of the level meters (13) will light up occasionally. Adjust if
necessary the quality of the sound with the equalizer (3).

LOOK OUT: The equalizer at each input is used to manipulate the sound of each of the
input sources. To correct the acoustic of the room it is probably best to use an
external equalizer.
5) To send the input signal through one of the effects outputs, first check if the desired effects bus
is free. This can be done by checking the input channel effects assign indication LED’s (4). If
the FX-1 LED does not light up, the FX-1 bus is free. If the FX-2 LED does not light up, the FX-
2 bus is free. If one of the LED’s is blinking red, the input channel effects assign potentiometer
(5) is in a wrong position. Then first turn the input channel effects assign potentiometer to its 12
o’ clock position, so the LED will stop blinking. To select the FX-1 bus, turn the input channel
effects assign potentiometer to the left, first, no effect will be audible, but the influence of the
effect will increase when the potentiometer is turned further to the left. When the potentiometer
is completely to the left, 100% of the signal will be influenced by the effect.
The same procedure can be followed to select FX-2, but then the potentiometer has to be
turned to the right.
When the FX-1 bus is selected, the according LED will light up green, same for the FX-2 bus.
On the other input channels and on the main mix, the according LED will light up red, to
indicate the according effects-bus is occupied.

6) Open up the fader (9) of the chosen input channel
7) Slide up one or both master faders (19) till desired volume is reached. Also open the monitor
fader (20), to hear the music at the DJ-booth.
8) The music in the DJ-booth can be manipulated with the monitor equalizer (21).
9) Correct if necessary the balance with button (6), for monophonic sound on master 1 and 2 set
switch (23) in mono position. For monophonic sound on monitor output, set switch (22) in mono
position.
10) If you like to use the crossfader (14), you can route the channel to the left (X) side of the
crossfader by putting the routing switch (7) on CF-X position. Or to the right (Y) side of the
