Controls at a Glance
MAKE UP GAIN
- restores the level of the signal after
compression.
COMP LINK
- for stereo work, the master twinQ
2
's "Compress",
"Attack" and "Release" control both master and slave twinQ
2
(the
corresponding controls on the slave twinQ
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.
LF
- controls the volume of Low Frequencies or "Bass" in the
audio spectrum. 15dB of boost or cut is available at the selected
frequency.
LF FREQ
- sets the frequency at which the LF control operates,
anywhere from 40Hz to 650Hz.
MID
- controls the Higher Middle frequencies in the audio
spectrum. 15dB of boost or cut is available at the selected
frequency.
MID FREQ
- sets the frequency at which the HM control operates,
anywhere from 300Hz to 5kHz.
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.
6kHz switch
- sets the frequency at which the HF control
operates: in for 6kHz, out for 12KHz.
EQ ON switch
- turns the Meequalizer on.
OUTPUT GAIN
- the volume control or "Fader" for the output of
the twinQ
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 twinQ
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.
