XLogic E Signature™ Channel Owner’s Manual
Dynamics
The unit 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 Slope Normally ‘Over Easy’, switchable to ‘Hard Knee’
Attack Time Normally 30mS per 20dB*, switchable to 3mS (‘Fast Att’)
Release Variable from 0.1 to 4 seconds
Release Slope Normally ‘Logarithmic’, switchable to ‘Linear’
The Compressor/Limiter has two different attack slope modes and two different release slope modes; ‘Hard
Knee’ & ‘Over Easy’ and ‘Logarithmic’ & ‘Linear’ respectively. As their names suggest these modes affect of
manner of response to incoming signals. Combining the two modes provides four very different modes of
compression and limiting with the ‘Hard Knee’ and ‘Linear’ modes giving far more dramatic compression
characteristics.
* When LK1 not fitted (default).
Expander/Gate
Controls:
Range Variable from 0 to 40dB
Threshold Variable from –30dB to +10dB
Attack Time Normally 1.5mS per 40dB, switchable to 100µs
Release Time Variable from 0.1 to 4 seconds
The side chain signal can be sourced either from the signal feeding the dynamics section or the external Key
input. The Filters and/or the EQ can be inserted in the sidechain.
LED meters independently indicate amount of compression and expansion.
Measurement Conditions
Signal applied to Line Input and measured at Output. All pots anti-clockwise and switches ‘out’ except for
Dynamics ‘IN’.
THD + N (+20dBu applied) < 0.1% at 1kHz
Output Headroom > +26dBu at onset of clipping
Frequency Response ±0.25dB from 20Hz to 20kHz
Noise < –73dBu
