OO
LF
- controls the volume of Low Frequencies or "Bass" in the
audio spectrum. 15dB of boost or cut is available at the selected
frequency.
120Hz switch
- sets the frequency at which the LF control
operates: in for 120Hz, out for 80Hz.
LM
- controls the Lower Middle frequencies in the audio
spectrum. 15dB of boost or cut is available at the selected
frequency.
LM FREQ
- sets the frequency at which the LM control operates,
anywhere from 200Hz to 2kHz.
HM
- controls the Higher Middle frequencies in the audio
spectrum. 15dB of boost or cut is available at the selected
frequency.
HM FREQ
- sets the frequency at which the HM control operates,
anywhere from 600Hz to 10kHz.
HF
- controls the volume of the High Frequencies or "Treble" in
the audio spectrum. 15dB of boost or cut is available at the
selected frequency.
7kHz switch
- sets the frequency at which the HF control
operates: in for 7kHz, out for 14KHz.
EQ ON switch
- turns the Meequalizer on.
Enhancer EFFECT
- sets the amount of enhancement.
Enhancer RANGE
- sets the frequency above which
enhancement is applied.
Enhancer Q
- adds a resonant peak at the frequency set by the
RANGE control.
Enhancer ON switch
- turns the Enhancer on.
De-Esser TUNE
- sets frequency at which gain reduction takes
place.
De-Esser LISTEN switch
- assists with tuning into the "Ess"
sound by listening to the output of the side chain filter.
DE-ESS
- sets the threshold above which gain reduction is
applied to the "Ess" sound. The red "De_Ess" LED lights when
gain reduction is taking place.
De-Esser ON switch
- turns the De-Esser on.
OUTPUT GAIN
- the volume control or "Fader" for the output of
the oneQ
2
.
PEAK FSD LED
- lights 6dB below clipping. "FSD" means "Full
Scale Digital" and this LED also warns you if the Digital Interface
is about to be overloaded.
'EXT CLK' LED
- illuminates when the oneQ
2
's digital output is
successfully locked to an external word clock
48V PHANTOM POWER switch
- feeds 48 volts to the
microphone XLR connectors, to power condenser microphones.
PAD switch
- selects 20dB attenuation of the Mic (XLR) inputs.
LINE switch
- selects the Line and INSTRument (1/4" jack)
inputs and deselects the Mic (XLR) input.
IRON switch
- selects transformer coupling of the Line (1/4" jack)
inputs.
Ø switch
- reverses the phase of all inputs.
MIC input
- low impedance microphone input. Parallels the Rear
Panel MIC socket. Use only one of these two sockets at a time.
INSTRument input
- high impedance input. Plugging in here
overrides anything plugged into the Line or Mic inputs.
PREAMP GAIN
- sets the amount of audio amplification. Too little
gain and the sound will be too quiet; too much and the signal
could become distorted.
PEAK LED
- lights 6dB below clipping.
HPF
- "high-pass filter". Mainly for use with microphones, this
helps remove stage rumble, handling noise and "pops".
METER
- analogue movement shows output signal level (VU),
preamp signal level, or the amount of Compressor gain reduction
(GR) in dB, depending on the settings of the Meter switches. The
'PRE' switch overrides both "VU" and "GR" metering.
COMPRESS
- sets the level of signal (or "Threshold") above
which the signal starts to be compressed.
SLOPE
- sets the compression ratio applied to signals above
threshold.
ATTACK
- sets how quickly the compressor responds to peaks
above threshold.
RELEASE
- sets the time taken for the signal to return to its
normal size after compression. In general, the longer the time,
the less obvious the compression.
MAKE UP GAIN
- restores the level of the signal after
compression.
POST EQ switch
- places the Compressor after the Meequalizer
in the signal path. (When this switch is out the Compressor is
before the Meequalizer in the signal path).
COMP LINK
- for stereo work, the master oneQ
2
's "Compress",
"Attack" and "Release" control both master and slave oneQ
2
(the
corresponding controls on the slave oneQ
2
are redundant). This
avoids stereo image shifts. All other controls still operate
independently on both master and slave and must be set the
same for correct stereo balance.
Compressor ON switch
- turns the compressor on.
