dbx Pro 566 - Manual (Page 12)

Rear Panel
LINE INPUTS
Both XLR and TRS 1/4Ó connectors allow balanced or unbalanced line-level devices to be connect-
ed to the input of the 566Õs Compressor section. The nominal input level can be set to either +4 dBu
or -10 dBV with the +4 dBu/-10 dBV switch.
INSTRUMENT INPUT
The instrument input is configured as a high impedance, unbalanced input, with tip hot, sleeve and
ring grounded. This input is for use with devices using passive or piezoelectric pickups (guitars etc.)
LINE OUTPUTS
Both XLR and TRS 1/4Ó connectors are provided for connecting either balanced or unbalanced line-
level devices to the 566. The nominal output level can be set to either +4 dBu or -10 dBV with the
+4 dBu/-10 dBV switch.
SIDECHAIN SEND
The Sidechain Send and Return allow external processing of the CompressorÕs detector signal. The
Sidechain Send is typically used to feed an external equalizer to produce compression that is triggered
mostly by a specific frequency band. The Sidechain Send jack taps the signal before the tube section
without interrupting the main output from the Compressor. This also allows the Sidechain Send to be
used as an additional pre-tube line level output. The nominal output level is +4 dBu.
SIDECHAIN RETURN
The output of an external device used for Sidechain processing of the detector circuit is connected
here. The nominal return level is +4 dBu.
