XLogic Channel Owner's Manual
Channel Dynamics
Each channel contains a complete dynamics section, the functions of which split into two areas;
a Compressor/Limiter and an Expander/Gate.
Compressor/Limiter
Controls:
Ratio (slope)
Threshold
Attack Time
Release
The XLogic Channel unit Compressor/Limiter has two modes of signal detection, Peak and RMS. As their names
suggest these modes of detection either act on peaks of the incoming signals or on their RMS levels. This gives
two very different modes of compression and limiting with Peak Mode giving far more dramatic compression
characteristics.
Expander/Gate
Controls:
Range
Threshold
Attack Time
Hold Time
Release Time
The side chain signal can be sourced either from the signal feeding the dynamic or the external Key input. Filters
and/or Equaliser can be inserted in the sidechain.
LED meters independently indicate amount of compression and expansion.
Measurement Conditions
Signal applied to Input A, output measured at Channel Output. All pots anti-clockwise and switches 'out' except
for Dynamics 'in'.
THD + N (+10dBu applied)
Signal at +14dBu applied to Input A, input gain set to +6dB, Compressor Threshold set at –20, Compressor Ratio
adjusted to give +4dBu at Output. RMS sensing mode selected.
THD + N
(Fast Attack Mode) †
THD + N
(Slow Attack Mode)
† LF distortion is consistent with attack and release time constants.
