Input Channel Section
3
[GAIN] Control
Adjusts the input level. When the [PAD] switch is off the
input level can be adjusted from –10 dB through –60 dB.
When the [PAD] switch is engaged the range is from +16
dB through –34 dB.
4
[L+R] Switch (stereo modules only)
When this switch is engaged the stereo input signal is
summed to a mono mix, allowing the stereo input
modules to be used as mono input modules, as required.
5
[ø] (Phase) Switch
Engaging this switch reverses the phase (also referred to
as the “polarity”) of the input signal.
HPF Block
The high-pass filter can be used to attenuate unwanted
low-frequency noise that can adversely affect the overall
sound.
6
[HPF] Switch and Control
The filter is activated when the switch engaged, and the
control can be used to adjust the high-pass filter cutoff
frequency from 20 Hz through 400 Hz. The filter has a
12-dB/oct. cutoff slope.
EQ Block
This 4-band equalizer features
individually-adjustable HIGH,
HI-MID, LO-MID, and LOW
bands for versatile shaping of
the channel signal. The HIGH
and LOW bands are switchable
between shelving and peaking
operation, while the HI-MID
and LO-MID bands are peaking
types.
7
EQ Controls
Two controls are provided for
each EQ band: the upper “Q”
control adjusts bandwidth,
while the lower concentric
control adjusts frequency (outer
control) and gain (inner
control). The HIGH and LOW
bands additionally have a
peaking/shelving switch that
determines the band’s mode of
operation: engaging the switch
selects the shelving mode.
* For all bands Q (bandwidth) can be adjusted from 0.5 ~ 3.0.
8
[EQ] Switch
Turns the 4-band EQ block on or off. When the [EQ]
switch indicator is off the EQ circuitry is bypassed. EQ
is active when the indicator is lit.
NOTE
Stereo modules feature concentric gain controls: the inner control
adjusts the gain of the left channel and the outer control adjusts
the gain of the right channel.
NOTE
To maintain the proper subjective signal level the left and right
channels are attenuated by 3 dB.
6
HIGH
1 kHz ~ 20 kHz, -15 dB ~ +15 dB (peaking
and shelving modes)
HI-MID
400 Hz ~ 8 kHz, -15 dB ~ +15 dB
LO-MID
80 Hz ~ 1.6 kHz, -15 dB ~ +15 dB
LOW
30 Hz ~ 600 Hz, -15 dB ~ +15 dB (peaking
and shelving modes)
