2. Product Overview
SSL E-Channel
The Waves SSL E-Channel is modeled after the SL4000 E Series console, combining the dynamics
section of the SL4000 channel strip with the “Black Knob” 242 EQ. The only noticeable change from
the hardware original is that the EQ and Dynamics sections are side-by-side rather than inline, to
better conform to computer screens.
SSL G-Channel
The Waves SSL G-Channel is modeled after the SL4000 G Series console, combining the dynamics
section of the SL4000 channel strip with the 383 G EQ. The only noticeable change from the
hardware original is that the EQ and Dynamics sections are side-by-side rather than inline, to better
conform to computer screens.
The E-Channel and G-Channel have latency of one sample.
Dynamics Section
The dynamics section consists of a soft-knee compressor/limiter and an expander/gate. Dynamics
can be switched to pre-equalizer (default) or post-equalizer (CH OUT.)
Although the same gain change circuitry is used for both the compressor/limiter and the
expander/gate, two dedicated level indicators illustrate activity for each device. Automatic gain
make-up, calculated from the Ratio and Threshold settings, is applied by the compressor to maintain
a steady output level. The default compressor attack time is program sensitive, responding to the
audio material’s wavefront.
The dynamics section’s threshold circuitry uses variable hysteresis, which allows the signal to decay
below its opening level. (Hysteresis is the lag between making a change in input, such as increasing
or decreasing power, and the response or effect of that change. Thus, the threshold’s variable
hysteresis circuitry allows for program-dependent dynamic processing.)
