Audio Connections
5.4 Side Chain
Outputs
The side chain uses a quasi-balanced ‘ground compensated’ output. When
connected to a balanced input, interference rejection equivalent to a fully
floating output can be obtained. Full headroom is available into any load of 2k
Ohms or greater. The signal ‘HOT, +, or in phase’ signal is to the jack plug tip.
The ‘COLD, -, or out of phase’ signal is to the ring with the shield being
connected directly to the chassis.
Connection to unbalanced inputs may be done by connecting the tip to the
signal input and the ring to the input shield. The DPR-422 shield may or may
not be connected to the equipment shield at the equipment end.
