Instrument Inputs

The stereo line inputs may be used as extra instrument inputs, especially if your MIDI keyboard or rack supplies a pre-mixed stereo signal.

When using the stereo line inputs as extra instrument inputs, you have access to the aux buses for effects processing.

Effects (Aux) Returns

The stereo line inputs may be used for returning the outputs of effects units.

Often it is useful to be able to send an effect into another effect. Echo sounds fatter when put through a stereo chorus or phaser. To do this use the aux send facility of the stereo line inputs. Just be sure not to send to an effect from its own output, creating feedback.

Certain stereo effects produce a perceived imbalance between the left and right channel levels.

When applying short left and right delays, the shortest one will always seem loudest. When pitch shifting up and down in wide stereo to thicken a sound, the signal shifted upwards will seem louder than one that goes down. In both cases use the BALANCE control (P28) to compensate.

+When carrying any stereo imaging exercise, don’t just rely on the control room monitors. Get a pair of headphones and listen in stereo and in reverse stereo, just in case you have any significant hearing discrepancies between your ears (and if you are in the habit of listening to high sound pressure levels (SPL’s), chances are you will).

Sometimes an engineer wants to narrow the stereo width of a reverb field. To do this you will have to come back on two mono channels to get independent PAN for the left and right signals.

Each of A + B and C + D is assignable to all or any of main mix (S32), or subgroup pairs 1+2 and 3+4 (S30, S31). Normally these will be assigned only to the main mix. However, provision is made for routing to the subgroups, in case you want to record the signal to tape, or mixdown via a subgroup.

6.3 Metering

Main mix/Solo/PFL level is displayed on a pair of highly-accurate 12 segment bargraph peak meters. LED’s indicate Power on (top left), +48 V phantom power present (top right), and whether the mono pre-fader listen bus (bottom left) or the stereo solo bus (bottom right) is engaged.

6.4 CHANNEL MODE

The CHANNEL MODE switch (S37) determines whether solo-in-place or pre-fader listen is assigned to the channel solo buttons.

SOLO

Solo is short for solo-in-place, and is the preferred method for auditioning an isolated signal, or group of signals. Whenever a SOLO button is pressed, all unselected channels are muted in the monitors. Stereo panning is maintained. The solo bus is derived from the output of the channel pans, aux sends, stereo line inputs and subgroups, too. The solo bus is always post-fader.

PFL

Pressing S37 once disengages the stereo solo bus, and replaces it with a separate mono PFL (pre-fader listen) bus. Now any channel which is solo-ed, isn’t. It is PFL-ed instead. PFL should always be used for gain-setting.
