pression) to 10 (a fast release where compression follows the envelope of the pro-
gram very tightly).
There is no absolute "right" way to set the DENSITY control. However, in general,
slower settings are useful for gating out noise present behind vocals and acoustic
instruments, while faster settings are useful for tightening up the sound of percussion
instruments (e.g., a kick or snare drum).
GAIN REDUCTION (dB) Meter: This meter shows the true peak gain reduction in
dB. If the red LED at the far left of the meter lights, no further gain reduction is
available.
FREQUENCY Control: Use the control to set the HIGHPASS frequency of the vari-
able filter used in the De-Esser circuitry. Settings between 4-8kHz will yield the best
results for vocal processing, while more extreme settings allow the 286A to be used
in other non-vocal applications.
THRESHOLD Control: Use this control to set the sensitivity of the De-Esser as a
percentage of the average program level at the 286A's input. This means that the De-
Esser tracks the input level so the amount of de-essing remains constant with changes
in input level.
The De-Esser 1dB and 6dB THRESHOLD LEDs light when the De-Esser is active.
These indicate (in dB) how much sibilance reduction is occurring due to the De-
Esser.
Note: The low and high frequency enhancers are off when their respective DETAIL controls are set to OFF.
LF DETAIL Control: The 286A's Low Frequency enhancement simultaneously
applies an 80Hz boost and 250Hz cut to the program. This lets you apply substantial
bass boost without making the program sound muddy or boomy due to excessive
mid-bass boost.
HF DETAIL Control: This control determines the amount of High Frequency spec-
tral-enhanced signal added to the input signal. Spectral Enhancement is a form of
dynamic phase and amplitude equalization. Continuous analysis of the input signal
intelligently and automatically determines the amount of equalization necessary at
each moment to achieve detailed, defined audio that is never shrill or over-sibilant.
Note: The Expander/Gate is off when the Expander/Gate THRESHOLD is set to OFF.
THRESHOLD (dB) Control and LEDs: Adjusting this control sets the level at
which the expander/gate will fully open and allow the signal at the input to pass
through to the output. Turing the knob fully counterclockwise (to OFF) allows the
gate to pass all signals unattenuated, effectively bypassing the gate. Turning the knob
fully clockwise causes the gate to attenaute input signals below approximately
+15dBu. The amount of attenaution depends on the setting of the Expander/Gate's
EXPANSION RATIO.
The THRESHOLD (-) LED (located to the right of the EXPANSION RATIO control)
lights when the signal is below the set THRESHOLD. The THRESHOLD (+) LED
lights when the signal is above the set THRESHOLD. The combination of these two
LEDs also serves as the "POWER ON" function, as one or the other is always on.
EXPANSION RATIO Control: This control sets the amount of attenuation applied
to the input signal once it is below the threshold, from gentle downward expansion
(appropriate for mixed program, vocals, etc.), to a hard gating effect (effective for
