215L High/Low
Sweep Filters
The 215L offers two sweepable cut filters, one each for
low and high frequencies. The original hardware is trans-
former coupled and uses a passive filter circuit design for
smooth tone.
215L Lo-Pass
The Lo-Pass (high cut) filter has a continuous range of 643
Hz to 40.8 kHz. The slope of this filter is 6 dB per octave.
The default value is 40 kHz.
215L Hi-Pass
The Ho-Pass (low cut) filter has a continuous range of 12
Hz to 596 Hz. The slope of this filter is 12 dB per octave.
The default value is 12 Hz.
215L SC (Dynamics Side Chain)
This button enables the side chain function for the 215L Sweep Filters. When
the 215L side chain is active, signal output from the 215L module is removed
from the audio path, and is instead routed to control the 235L and 225L dy-
namics modules in parallel as shown in the diagram below.
To listen to the side chain key, simply disengage SC to hear the equalized sig-
nal.
Note: The 215L module must be enabled for the 215L side chain to function.
215L On
This button enables the 215L module. The module is active when the button’s
green indicator is lit.
Note: UAD DSP load is reduced when this module is inactive (unless DSP
LoadLock is enabled).
