Auxiliary 1 is a fixed level and auxiliary 2 has a level control (6), which acts purely as
an attenuator - when set at 10 and source post-fader the output tracks with, and is at
the same level as the L/R outputs from the module. This also applies to the post-fader
position of auxiliary 1.
The unbalanced channel output is available on a XLR on the connector panel in line
with the input connector. The level of the direct out signal is controlled by preset (3).
The channel direct output signal can be from either the pre-fader or post-fader point
and is selected by toggle switch (4). A six way rotary switch (5) enables different
signals, other than the direct output signal, to be fed to the channel output. These are
the L and R mixes, a mono of the main L and R mixes (MIX) and AUX 1 and AUX 2.
A panoramic potentiometer - panpot - (7) routes the module’s signal proportionately
between the left and right mix busses.
The MUTE switch (8) follows the panoramic control. When selected it prevents the
input signal reaching the main mix busses. An internal DIL switch controls whether the
auxiliaries appear pre or post the mute switch. The factory setting is that the
auxiliaries are not affected by the mute switch. The channel output signal is not
affected by the mute function.
Pre-fader listen (9) with its LED indicator routes the module’s signal to the
monitor/PFL mix buss for auditioning on headphones.
An overload LED (11) illuminates 3dB before clipping at the input to the fader.
The Penny & Giles fader (23) is calibrated 10dB from its fully open position,
allowing the operator to work with 10dB of gain in reserve. Faders on adjacent
modules can be coupled for stereo operation by the use of standard ganging clips.
