Combined Turntable-/ line-/ microphone channels (3, 4 and 5)
These three stereo channels have three inputs (phono for turntables, line for equipment like CD-
players and MD-recorders and mic for a microphone input), Gain control, 3-way tone control,
balance and pre-fader listening.
DISC / LINE Input selector. Normally the line input is selected. When
pushed the phono input is selected. The LED is an
overload indicator.
MIC Input selector. When pushed the MIC input will be
activated.
GAIN Determines the pre-adjustment of the volume for the
microphone as well as both stereo disc/line inputs.
Effect sends/ Cleanfeed and phantom jumpers
Each channel has an internal jumper to enable or disable the channel to send it’s signal to the
effect-send output. It’s also possible to send the signal to the effect output only when the
microphone input is active.
To adjust the settings the mixer has to be opened. Each module has two jumpers. The jumper to
control the cleanfeed settings can be found near to the band-cable. See the drawing.
The effect-send output is post-fader: the volume is dependent of the fader.
The output of the effect-generator can be connected to the effect-return input.
This return input can also be used as an extra input.
Each microphone input has a switchable phantom-power. This can be done
with the jumper near to the connectorboard. See the drawing above.

Cleanfeed off: The channels signal is not send to the effect output. This is the default setting.
Cleanfeed on: The channels signal is send to the effect-send output. This can be used w
h
the effect-send is used as a cleanfeed. The signal of this channel is send to the telephon
e
hybrid. The cleanfeed of the channel to which the hybrid is connected must be set to off.
Cleanfeed sw: The channels signal is send to the effect output only when the microphone input
is selected. This can be used when an effect-generator (echo etc.) is connected to the effect-
send output.
Phantompower is switched off. This is the default setting.
Phantompower is active.
