Control panel

■Channel control section 1Input selector

This button selects the input connector for the channel.
When A ( ) is selected, the input signal will be taken from the rear
panel INPUT A connector (balanced XLR type). When B ( ) is
selected, the input signal will be taken from the rear panel INPUT B con-
nector (balanced phone jack).
2PAD switch
This pad switch provides 20dB of level reduction.
If the input signal level is too high and the 3 GAIN control will not
reduce it sufficiently, use this pad switch.
3GAIN 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 4 peak indicator lights occasionally. If you
wish to further reduce the input level, use the 2 PAD switch.
4PEAK indicator
This indicator detects peak levels after the EQ.
It will light red at 3dB before clipping to warn that clipping level has
nearly been reached.
580Hz high-pass filter switch
This switch turns on/off a high-pass filter that cuts the signal below 80Hz
at 12dB/octave.
6Equalizer
The equalizer section provides ±15dB of control over the high, mid and
low ranges at the following frequencies.
HIGH: 12kHz
MID: 2.5kHz
LOW: 80Hz
Frequency response will be flat when the knob is at the “▼” position.
