signals. Switching to the bypass (EQ) position enables immediate comparison of the
original unaltered signals without the need to disturb the chosen settings.
HF (2). – High frequency equalisation control giving ±12dB at 10kHz, variable slope.
MF (3). – Mid frequency equalisation control centred on 2.4 kHz giving ±15dB peak
and dip.
LF (4). – Low frequency equalisation control giving ±10dB at 100Hz, variable
turnover.
Push button switched L (6) and R (7) control the routing of the channel left and right
signals to the main left and right outputs. If both L and R are selected then the left
signal of the channel is routed to the main left output and the right signal of the
channel to the main right output.
If only L is engaged then the left input signal is routed to both left and right outputs.
Similarly the R push switch routes the right input signal to both left and right outputs.
PFL (8) – Pre-fader listen routes the signal at the pre-fader point to the monitor,
(headphones). This signal overrides other signals on the monitor. The LED (9)
indicates PFL is selected on a particular input channel.
L and R overload LED indicators (10) indicate when signal overload is approaching
and illuminate 3dB before dipping on the respective channel.
Should one of the OL indicators light, the BAL control should be rotated away from
that channel toward the other irrespective of the fader position. Should both L and R
overload indicators light, the EQ should be checked for correct adjustment before
resorting to reducing the external signal level.
Linear fader (11) is a 65mm length, conductive – plastic stereo fader. This controls
the amount of stereo input signal mixed to the main left and right groups, which are
selected and routed via the routing push-button switches.
