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.
