Professional stereo power amplifier.
CONTROLS AND FUNCTIONS
FRONT PANEL
POWER AMPLIFIER
1.- CH A and CH B output volume controls.
2.- LED indicator
CLIP: LED signal peak indicator of each channel. If they light up slightly or occasionally, the output
volume must be reduced. If the LED indicator is permanently lit, it is due to the input signal having a
very high level. In this case, reduce the input signal volume.
SIGNAL: LED input signal indicator in the amplifier. It lights up when there is a signal present in the
amplifier input.
POWER AMPLIFIER
PROTECTION: LED protection indicator. It lights up when the amplifier's protection is activated due to
temperature, overload, short -circuit, ultrasound or RF. With the protection activated the audio output
is cut off. In this case, switch off the amplifier, correct the causes of the fault and let the device reset
itself for a few minutes before switching it back on.
POWER: amplifier LED power indicator.
3.- On/off switch.
REAR PANEL
1.- INPUT CH A/CH B: channels A and B line level signal balanced inputs, XLR connectors.
2.- LINK CH A/CH B: channels A and B line level signal balanced outputs, XLR connectors.
3.- SENSITIVITY: input sensitivity selector.
4.- MODE: operating mode selector. For more information, go to the CONNECTION section of this manual.
5.- OUTPUT CH A/CH B: channels A and B loudspeaker output terminals to connect loudspeakers.
6.- FUSE: AC power supply circuit protective fuse.
7.- 30 Hz HI-PASS: high pass filter selecto.
8.- GND/LIFT: this selector is normally in the GND position. If the installation has ground noises, place the
selector in the LIFT position in order to disconnect the ground from the device's earth.
9.- AC power supply cable.
