Group/Stereo Input
Stereo Input
1
The -10 switch changes the nominal input level from +4dBu, when the switch
is released, to -10dBV, when the switch is depressed.
EQ
2
The stereo 2-band shelving EQ has a +/-15dB cut and boost at 3kHz, which is
controlled by the HF control, and a +/-15dB cut and boost at 150Hz, which is
controlled by the LF control.
Routing
3
The output of the EQ section is normally fed to the Foldback level controls,
marked FB1/L and FB2/R. The FB1/L control sends the Left stereo signal to the
FBL bus and also a mono (L+R) signal to the FB1S bus. The FB2/R control sends
the Right stereo signal to the FBR bus and also a mono (L+R) to the FB2S bus.
These buses are connected to the Foldback Master & Studio Outputs panel.
4
The output of the EQ section is also fed to the Rotary FADER. The Fader has
a max. gain of +10dB. It is advisable to turn this fader fully off (anti-clockwise) if
the Stereo Input in question is not being used.
5
The Fader feeds the BALance control, which adjusts the relative levels of the
Left and Right stereo image.
6
The output of the Balance control normally feeds the MIXL and MIXR buses,
via the MIX switch; the output of the Balance control is switched over to a pair of
Group buses when the MIX switch is depressed: the Group buses are identified on
the panel legend, under the word, ’MIX’.
7
The Foldback level controls are fed post-fade when the POST switch is
depressed.
8
The SOLO switch is a soft switch, i.e. this switch provides an input to the
Automation. The Automation , in turn, controls the PFL circuit, which switches a
mono (L+R) signal onto the PFL bus. The adjacent LED illuminates when the PFL
circuit is active on any particular Stereo Input panel.
The Automation also activates the PFL circuit in the Control-room Phones/Speakers
Panel: this feeds the Signal from the Stereo Input to the Control-room
Phones/Speakers.
9
The CUT switch is a soft switch, i.e. this switch provides an input to the
Automation. The Automation, in turn, controls the Cut circuit, which is post-fade.
GROUP
The 8 Group buses are processed in pairs. There are, therefore, four Group panels.
The pair of Groups which each panel controls is marked on the panel.
The Group buses have two functions. The first is to allow you to route a signal from
an Input Channel to a different numbered Tape send. The second is to allow track
