CONTROLS AND FUNCTIONS (
rear)
28. MAINS CABLE:
connect this cable to a 230V/50Hz mains outlet. Before use, inspect the cable to be
sure it’s not damaged!
29. FADER CONTROL:
When connected to these inputs, compatible CD-players can be controlled by the
fader starts of this mixer.
30. MASTER1 BALANCED OUTPUT:
The XLR-connectors can be used to connect this mixer to any
balanced amplifier input, using special balanced signal cables.
31. MASTER UNBALANCED OUTPUTS:
The “master 1” output has the same output signal as the
balanced master output(30) but unbalanced. The “master 2” output carries the same signal but can be
controlled independently by the master2 level/balance (19/20). Use the outputs to connect unbalanced
amplifiers.
32. RECORD OUTPUT:
Carries the same signal as the master outputs but is not influenced by the master
level, balance and mono/stereo controls. Used to connect analog recording equipment. You can also
connect a computer for direct digital recording, see USB connections (42).
33. INPUT CHANNEL 5:
used to connect two different line level audio signals. You can also connect a PC
via the USB connectors (see 42). The input source selector (10) on the front determines which input will
be active.
34. INPUT CHANNEL 4:
used to connect a turntable and/or a line level audio signal. You can also connect a
PC via the USB connectors (see 42). The input source selector (10) on the front determines which input
will be active.
35. GROUND (GND) CONNECTION:
Many Turntables have a GND-connection. It is preferable to connect
this signal ground to the GND-connector. If your turntable does not have a ground wire, you don’t have
to use this connector.
36. INPUT CHANNEL 3:
used to connect a turntable and/or a line level audio signal. The input source
selector (10) on the front determines which input will be active.
37. INPUT CHANNEL 2:
used to connect two different line level audio signals. Refer to switch (39) to
change one line input to microphone level. The input source selector (10) on the front determines which
input will be active.
38. MIC2 INPUT:
Used to connect a balanced microphone to channel 2. Refer to switch (39) to change the
CD1 input to mic2.
39. MIC2/CD1 SWITCH:
This switch makes it possible to switch between the CD1 input (37) and the mic2
input (38) on channel2.
40. LINE INPUT CHANNEL1:
used to connect a line level audio signal to channel1.
41. MIC1 INPUT CHANNEL1:
used to connect a microphone to channel1.
42. USB CONNECTIONS:
two bidirectional USB connections (USB1 for CH4 ~ USB2 for CH5). You can
connect any PC through these USB connections. The PC/Mac will detect your mixer as a sound card,
normally no drivers are needed. Since both USB ports are bidirectional you are able to play music on
your computer and mix this music with other sources like CD, phono, etc. At the same time you can
record your mix on your computer with the same USB connection!
43. OUTPUT TRIMMER:
This potentiometer is used to reduce the output level of the mixer to protect the
connected amplifiers and speaker cabinets. (Attention: the output level can be reduced to zero. If you
don’t have any signal on the master output, first check if this potentiometer is accidentally put to zero.)

CROSSFADER STARTS
The crossfader integrates the optical fader start switches. These fader starts are compatible with all current
JB Systems CD-players. This is how it works:
A. CROSSFADER IN LEFT POSITION:
CD-player connected to fader start connector A is playing,
the other CD-player is paused.
B. CROSSFADER MOVES TO THE RIGHT:
CD-player connected to fader start connector A stops
playing, returns to its previously programmed cue point and
waits in pause. The other CD-player starts playing from its
previously programmed cue point.
C. CROSSFADER IN RIGHT POSITION:
CD-player connected to fader start connector B is playing,
the other CD-player is paused.
D. CROSSFADER MOVES TO THE LEFT:
CD-player connected to fader start connector B stops
playing, returns to its previously programmed cue point and
waits
in pause. The other CD-player starts playing from its
previously programmed cue point.
Important:
Both fader start switches must be in “ON” position!
CHANGING THE FADERS
One of the big advantages of this mixer is the possibility to change the channel faders
This is what you must do to change a channel fader:
Remove the fader knobs from the faders.
Remove the 8 screws that hold the small front panel around
the faders.
Remove the 3 screws of the fader you want to change.
Gently remove the fader from its position and unplug the
connector from the main board. (do NOT pull the cable!)
Put the new fader gently in place. Be sure to plug the
connector in the connector base on the mixer PCB-board.
Put the 3 screws from the fader back in place
Put the small front plate back in place with the 8 screws.
Done!
This is what you must do to change the cross fader:
Remove the fader knob from the cross fader.
Remove the 2 screws that keep the cross fader in place.
Gently remove the fader and the cover plate from their position.
Unplug the cross fader from the cable (unplug the cable by pulling the connector, NOT the cable!)
Press the new cross fader on the cable.
Put the cross fader back in place with the small cover plate and the 2 screws.
Done!
