connectionS, ConTRoLS, AnD InDICAToRS:
10 SIGnAL LeD InPUT 1 - 4
The signal LED lights up green when an audio
signal is present at the input of the respective
channel. The LED lights up red when the optimum
volume level (0 dB) is achieved.
11 VoLUMe InPUT 1 - 4
Volume control for channel INPUT 1 to 4.
12 SoURCe CD / PHono-LIne InPUT 2 - 3
Switch with built-in red LED to select the input
source for INPUT channels 2 and 3. If the switch is
not pressed, the CD input is selected as the signal
source, in the pressed position, the PHONO/LINE
input is selected (LED is on).
13 SoURCe LIne / CD-FoH InPUT 4
Switch with built-in red LED to select the input
source for INPUT channel 4. If the switch is not
pressed, the LINE input is selected as the signal
source, in the pressed position, the CD/FOH input
is selected (LED is on).
14 CUe InPUT 1 - 4
Cue switch with built-in red LED for INPUT channels
1 - 4. If the switch is pressed (LED is on), the input
signal is routed to the headphone output on the
front panel of the device. The signal is sourced before
the volume control of each channel, therefore it is
independent of the setting of the volume control.
15 TALKoVeR
Talkover feature for microphone channels 1 and
2. If the TALKOVER knob is turned fully to the left,
the Talkover feature is disabled. The further the
TALKOVER knob is turned to the right, the stronger
the signals connected to INPUT 1 - 4 will be
suppressed by the incoming microphone signal.
The threshold value is determined using the T/O
LEVEL control set on the rear panel (sensitivity
with which the Talkover feature reacts to the
incoming microphone signal). The Talkover feature
is not available for the ZONE output when a signal
source from INPUT 2 - 4 is selected using the
SOURCE switch.
16 MASTeR LeVeL
Volume control for the MASTER channel.
17 MASTeR eQ HIGH
Equalizer high band for the MASTER channel.
When turned to the left, levels are lowered, when
turned to the right, they are raised. In the centre
position (resting point), the equalizer is inactive.
