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) Variable from 1 to infinity (limit)
Threshold Variable from +10dB to –30dB
Attack Time Normally auto sensing, switchable to 1mSec
Release Variable from 0.1 to 4 seconds
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 Variable from 0 to 40dB
Threshold Variable from –30dB to +10dB
Attack Time Normally auto-sensing, switchable to 150µs
Hold Time Variable from 0 to 4 seconds
Release Time Variable from 0.1 to 4 seconds
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) < 0.01% at 1kHz
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 < 0.3% at 1kHz
(Fast Attack Mode) † < 0.05% at 10kHz
THD + N < 0.03% at 1kHz
(Slow Attack Mode) < 0.05% at 10kHz
† LF distortion is consistent with attack and release time constants.
Output Headroom > +26dBu at onset of clipping
Frequency Response ±0.2dB from 20Hz to 20kHz
–3dB at 130kHz
Noise < –86dBu
