stereo returns
features
The HPW has 2 stereo returns located within the Master module. These inputs are
designed to accept line level balanced signals (from an effects unit, a CD player, or other
line level source) on their 1/4” TRS balanced jacks.
gain
This control adjusts the gain of the input amplifiers. Both Left and Right circuits are
simultaneously adjusted. Unity gain is at the mid-point (with a detent), min and max gain
adjust is 20dB. The stereo inputs were designed for line-level sources, and can accom-
modate a wide range of input levels.
stereo lo-cut filter
This filter reduces or eliminates unwanted low frequencies to clean out the mud that
often accompanies reverbs or synths. The cut-off frequency of the filter is 150 Hz
and the slope is -18dB per octave. This type of filter is also referred to as a Hi-pass
filter (HPF). It allows the hi-frequencies to pass, but stops the lo-frequencies.
lo cut switch
When the button is in the “OUT” position, stereo Lo-Cut filter is not engaged
When the button is in the “IN” position, stereo Lo-Cut filter is on.

Reverbs can have a
sizable amount of
low frequency rumble that
is best removed with a low
cut filter.
Some synth patches have so
much low frequency energy
that they lose definition and
need high pass filtering.
Engaging the Lo-Cut filter
can eliminate these power-
stealing low frequencies.
