Functional Description
The theatre mono input is provided with XLR and jack connectors, the XLR may
be used for any level of input signal; inserting a jack automatically disconnects the
XLR socket, and applies the jack signal (HI-Z I/P) to the input. The jack socket only
operates on the lower sensitivity range.
The channel is provided with an Insert Point using a Ground Compensated Send
(optionally balanced) and Balanced Return. The Insert Point may be configured as
pre or post-EQ ( the factory default is pre-EQ).
1
The 48V switch applies 48V phantom power to the input XLR. Note that the
48V is never applied to the jack socket
2
The SENS (sensitivity) control adjusts the sensitivity of both the XLR and jack
inputs, and in combination with the RNGE switch gives two sensitivity ranges:
-2dBu to -70dBu, and +10dBu to -20dBu.
3
The RNGE (Range) switch lowers the sensitivity of the input when pressed,
allowing line level signals to be used.
The ∅ (Phase) switch reverses the phase of the selected input when pressed.
4
The switch should normally be released.
5
This switch inserts a second-order HI-PASS FILTER into the channel path.
The frequency is fixed at 100Hz.
Equaliser
6
The EQ section has four bands, with sweep peak/dip on all four bands using
four dual-concentric pots. In addition the HF and LF bands have switchable
bell/shelving operation. The SHLF switch switches the response to shelving in each
case when pressed. When in peak/dip mode the Q of the LF and HF bands is fixed
at 1.5.
•
The HF control gives 15dB of cut or boost from 1 to 16kHz.
•
The LF control gives 15dB of cut or boost from 27 - 500 Hz.
•
The HI-MID control gives 15dB of cut or boost from 400Hz - 7kHz.
•
The LO-MID control gives 15dB of cut or boost from 70Hz - 1.1kHz.
•
The Q of the two mid bands is switchable between 1.3 and 2.6 with the HI-Q
buttons: when a button is depressed the Q value of 2.6 is selected, this gives a
steeper notch in the response curve.
7
The EQ section is switched in by the EQ switch. Toggling this switch provides
a simple method of hearing the effect of the equaliser settings.

Auxiliary Sends

8
Signal is sent to the Aux 1 - 8 busses via individual Level Pots. These have
unity gain when fully clockwise, and are switched pre or post-fader in pairs by the
PRE buttons.
The pre-fade signal may be sourced pre-fade & post-mute, pre-mute, or pre-EQ &
pre-insert in two blocks of four sends, using push-on jumpers.
