FRONT PANEL CONTROLS – CHANNEL CONTROL SECTION
(1). PEAK LED INDICATOR
This LED indicators lets you check the level of the signal input to the channel.
The peak indicator lights when the input signal reaches 5dB below the
channel’s clipping point. This indicator shows the level of the Post-EQ /
pre-fader signal. If the PEAK indicator lights more than briefly on high-level
transients, you should use the GAIN control to decrease the input sensitivity
of the channel. If this does not work, reduce the output level of the connected
source.
(2). GAIN CONTROL
According to the level of the input signal, use this knob to adjust the input to
an appropriate level. The best balance of S/N and dynamic range will be
achieved if you adjust the GAIN control so that the peak indicator lights
occasionally. This control adjusts the channel’s mic input sensitivity between
-50dB and -6dB and the line input sensitivity between -30dB and +14dB. The
mono/stereo combination input channels have a sensitivity of +20dB to
-20dB.
(3). HPF (High-Pass Filter, cut frequencies below 75Hz)
This switch toggles the HPF on or off. To turn the HPF on, press the switch in
( ).
(4). 3 BAND EQUALIZER CONTROLS
This is a 3-band equalizer with center frequencies, range and type as shown
below. The frequency response is flat when all knobs are in the “0” position.
CONTROL MAX.
BOOST/CUT
FREQUENCY TYPE
HIGH ±15dB 12kHz Shelving
MID ±12dB 2.5kHz Peaking
LOW ±15dB 80Hz Shelving
(5). AUX CONTROLS
This knobs control the level of the signals sent to AUX bus.
(6).PRE/POST SWITCH
This button determines whether the AUX signal is Pre or Post fader. Pre
means not affected by the position of the channel fader. Post means is
affected by the position of the channel fader.
(7). EFX CONTROLS
This knobs control the level of the signals sent to EFX bus. The channel signals mixed by this bus have their overall level
set by the EFX SEND Control to the EFX SEND jack on the front panel. The EFX bus signal is also fed into the internal
digital signal processor. Since this control is placed after the channel fader, the signal level will be affected by the
channel fader setting.
