A-channel line inputs

These 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. This 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 porvide 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

These also accept balanced or unbalanced 1/4" jacks and are switchable, 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 sockets, 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.
