A and B-channel input section

Fig. 7.8:

A-channel line inputs
The A-channel line inputs accept balanced or unbalanced 1/4"

jacks, tip = hot, ring = cold and sleeve = ground/screen.
Mic inputs
These are via XLR-type connectors, wired pin 1 = ground, pin 2 =

hot and pin 3 = cold, for balanced low-level operation. Since most

quality capacitor microphones require a 48 V DC offset to charge

the plates, phantom power is provided and can be switched on

or off in three blocks of eight via a switch situated below channels

8, 16 and 24.

Care should be taken not to plug microphones into

the console (or stagebox / wallbox) while the phantom

power is on. Also, mute the monitor / PA speaker when

turning phantom power on or off. Allow one minute

after powering up for the system to equilibrate before

setting input gains.

Channel inserts
These provide for unbalanced send and return from a single

stereo jack socket. Wiring is: tip = out, ring = in and sleeve =

ground/screen.
Direct outputs
This tap comes from just after the channel fader. Unbalanced

1/4" jacks.
B-channel inputs/tape returns
They also accept balanced or unbalanced 1/4" jacks and are swit-

chable, in groups of eight, between -10 dBV (unbalanced) and +4

dBu (balanced), corresponding to the standard semi-professional

and professional operating levels and configurations respectively.

Consult your multitrack manual to find out which one applies.

Subgroup outputs/tape sends
The eight subgroups are each connected to two stereo jack sock-

ets, for easy patching into 16 track recording systems (or 24 track, if

you use Y-adaptors). Once again, the operating level is switchable

between +4 dBu and -10 dBV in two banks of (2x) 4.
