Chapter 53: SSL E Channel Strip
Filters
In addition to the four-band EQ, UAD SSL E
Channel Strip offers individual high and low
pass filters.
When the Filter control is at minimum value
(fully counter-clockwise), the filter is disabled.
The control ranges and sonics of these filters
can be changed between “Black” and
“Brown” modes with the EQ Type switch. See
“EQ Type” on page 530
for more information.
High Pass
The left knob determines the cutoff frequency for the high pass filter. Rotate
clockwise to reduce low frequencies.
In Black mode, the slope of the high pass filter is 18 dB per octave and the
available range is 16 Hz to 350 Hz. In Brown mode, the slope of the high
pass filter is 12 dB per octave and the available range is 20Hz to 350 Hz.
Low Pass
The right knob determines the cutoff frequency for the low pass filter. Rotate
clockwise to reduce high frequencies.
In Black mode the slope of the low pass filter is 12 dB per octave and the
available range is 22 kHz to 3 kHz. In Brown mode the slope of the low pass
filter is 12 dB per octave and the available range is 16 kHz to 3 kHz.
Filters to
Sidechain
(DYN SC)
This button enables the Filters sidechain function. When the Filters sidechain
is active, signal output from the Filters module is removed from the audio path
and is instead routed to control (“key”) the dynamics module.
Sidechaining is typically used for de-essing and similar frequency-conscious
techniques. To listen to the sidechain key, simply disengage DYN SC to hear
the filtered signal. The sidechain dynamics/EQ implementations are true ste-
reo when used in a stereo in/stereo out (“SISO”) configuration.
Note:
The Filters module must be active (not at minimum value) in conjunction
with the Filters DYN SC button for the Filters sidechain to function. An addi-
tional dynamics sidechain is available in the EQ section (
“EQ to Sidechain
(DYN SC)” on page 533
).
