Solid State Logic 82S6XL090A Dynamics, Compressor/Limiter Controls, Expander/Gate Controls

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
