quality. Therefore, you cannot compare the “before” and “after” honestly. “Hard wire” effectively removes the unit

from the signal path.

Tip: , To test any unit (even a guitar pedal) for “true hard wire bypass” design, place it in bypass and disconnect the power

(AC or battery). If the unit still passes audio, it’s a true hard wire bypass circuit.

Trivia: Known in the inner circles as a “sober switch”.

2. SIDECHAIN BUTTONS (a Quadrilogy)

[sidechain buttons pictured above]

INTRO

A sidechain circuit provides what the gain reduction element in a compressor “hears.” When cleverly designed it allows the compressor

to become more or less sensitive to a speciﬁc frequency or group of frequencies. In other words, let’s say you’re committing a mix. The

ﬁnal feels like it needs more gain reduction (i.e. compression/limiting), but when engaged, every time the kick drum sounds, the entire

mix drops in level. By reducing the compressor’s sensitivity to low frequency content (i.e. BASS!), it will allow the kick drum to strike,

without over-triggering the compressor.

BASS CUT

Feature: Reduces sensitivity to low frequency energy. (i.e. the compressor won’t react as much to bass).

Beneﬁt: Keeps the compressor from “dunking” with loud bass or kick drum levels. (i.e. more bass, while controlling the rest)

Technical: bass cut introduces a 6dB per octave ﬁlter, 3dB down at 60Hz.

SIBILANCE BOOST

Feature: Increases sensitivity to high frequency energy. (i.e. the

compressor will react more to the top end).

Beneﬁt: Tame the harshness without resorting to EQ changes.
