FRONT PANEL DESCRIPTION
Gain (1)
The GAIN knob on each input channel establishes the nominal operating level for
the channel. The input gain can be adjusted over a wide range to compensate for
soft voice or very loud drum. To maximize the signal-to-noise ratio, the gain should
be set to proper level.
High Control (2)
An active tone control(with boost or cut of up to 15dB) that varies the level of the
high frequency range, the center frequency is 10kHz.
Caution: Excessive low frequency boost causes greater power consumption and
increase the possibility of speaker damage.
4 MIC/LINE input channels with GAIN, 2-band EQ and VOLUME controllers
Phantom power switches on channel 1 and 2
Channel 1 with priority switch, auto-mute other input channels
Channel 4 accepts Mp3 player signal by input selector

Power supply: AC110V/50Hz or DC24V
Each input channel has a 2-band equalizer. The 2-band equalizer provides
boost or cut of up to 15dB. In the center position, the equalizer is off(flat).
Low Control (3)
An active tone control(with boost or cut of up to 15dB) that varies the level of the
low frequency range, the center frequency is 100Hz.
Volume Control (4)
This VOL knob on each input channel controls the channel output volume.
On LED, 1/2/3/4 Select LED, Phan LED, Clip LED (5)
