AUDIOilN, OUT. These two S^arcuit phone jacks are
the Input and Output. As
marked, these jacks are the
standard tip/plus, ring/minus, and sieeve/ground.
2
SIDECHAIN;IN. This jack provides a
direct input (optional) to the
rms-detector
circuitry. It is used for
connecting a signal processor for altermg the
dynamic
response of the 166. An example would
be an equalizer to make the
compression or
the gating
frequency-sensitive (see Sidechain
Monitor, below). This input uses a
2-circuit phone jack:
tip
is
plus, sleeve ground.

GATE:THRESHOLD and RELease
RATErFAST,
SLOW.
The 1
66
gate is a
below-
threshold attenuator with two
release rates. The Threshold kr>ob sets the level
below which the 1
66
gates
~
attenuates
—
the signal.
The LED lights whenever this
takes place.
As marked, the threshold ranges from
+10
to
below
-60
dB; Off, of
course,
inactivates the gate. The amount
of attenuation is set at 40
dB.
The RELease
RATE
switch
controls how fast the signal
gets attenuated. In the
Slow position (in), the rate is
useful for general-purpose
gating of
noise
behind
vocals
and acoustic instruments
—
about 1 0
dB/s. In the Fast position, the rate is
very fast (1000
dB/s), useful
for
tightening
up
the sound
of
percussion (e.g.,
kick or
snare drum) and drying up
leakage from other instruments
into percussion tracks.
The attack rate of the gate (which
controls how fast the signal is
restored after
being attenuated) is internally set to be very
fast
—
fast enough to
edlow
all
of the
transient at the beginning of a note to
come through.
4 OVEREASY
COMPRESSOR:THRESHOLD
and RATIO.
The Threshold
knob
sets the
point at
which dbx's well-known
Over-
Easy
circuit begins to compress the
dyna-
mic remge
of the signal. The calibration
numbers
refer to the middle of the
Over-
Easy curve (see
right); at an Infinity:!
ratio, they
denote the point where there's
approximately
6
dB of compression.
The
OverEasy sound is musical and
unobtru-
sive, without the "held-back"
feeling of
other compressors.
