1.- INPUT 1-3 and AUX: controls to regulate the volume of the inputs 1 to 3 and the aux input.
2.- BASS: reinforces or attenuates bass frequencies ±10 dB.
3.- TREBLE: reinforces or attenuates bass frequencies ± 10 dB.
4.- MASTER: control that regulates the general output volume for all the inputs.
5.- OUTPUT LEVEL: LED output signal level indicators. It regulates the individual volume controls for
the inputs or the general (MASTER) output volume, so that the level does not exceed the green LED
indicators. The red LED indicators indicate saturation or a distorted signal which could cause damage
to the speakers or the amplifier.
6.- POWER: on/off switch for the amplifier.

1.- Ventilation grille: to ventilate the final stage of power.
2.- GND. Earth: screw to earth the amplifier, to be used in the case of the mains connection not having
one incorporated.
3.- 115 V/230 V: power supply voltage selector.
4.- AC socket: for the AC power supply cable connection.
5.- AMP IN/ PRE OUT: the connection bridge between the two RCA connectors communicates the output
signal from the PRE OUT with the AMP IN.
