EURODESK SX4882 User Manual
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 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.
