3.0 EXTERNAL CONNECTIONS
3.1 SIDECHAIN
The Side chain TRS jack allows connection of an external processor such as an
equaliser for frequency sensitive compression e.g. de-essing.
This is an unbalanced insert with Ring wired as Send and tip wired as return.
Please note:
Plugging a jack into the side chain connector breaks the control signal path which
must then be completed by the externally connected equipment.
3.2 INPUT
Electronically balanced Input with pin 2 wired hot (signal +).
Unbalanced operation is possible by joining pin 3 to pin 1 (signal ground) and
using pin 2 as signal hot (+).
Please note:
To maintain correct signal levels in un-balanced applications, pin 3 must be
joined to pin 1 and not left un-connected.
3.3 OUTPUT
Electronically balanced Output with pin 2 wired hot (signal +).
For un-balanced operation pin 3 can be joined to pin 1 i.e. pin 2 = signal hot and
pins 1&3 = ground (screen).
Please note:
To maintain correct signal levels in un-balanced applications, pin 3 must be
joined to pin 1 and not left un-connected.
3.4 LEVEL
These switches select the input and output operating level for each channel
between +4dBu (switch out) and -10dBV (switch in).
The Side Chain insert operates at -2dBu in both +4dBu and -10dBV modes.
