CONTROLS AND FUNCTIONS
FRONT PANEL
1. MASTER SWITCH
It switches the amplifier on / off (interrupting both the phases).
2. POWER ON INDICATOR
Green LED indicating correct operation.
3. VOLUME CONTROLS
Controls to adjust the volume levels of the two channels separately.
In MONO and BRIDGE modes, use the control CH1 only.
4. PEAK LIMITER INDICATORS
Red LEDs indicating the maximum amplification level has been reached (peak) in the respective
channels. If a LED stays lit continuously, the input signal is excessive.
5. SIGNAL -20 dB INDICATOR
Green LEDs indicating the presence of the signal in the final stages of the respective channels (at
a level of at least -20dB).
6. MUTE / PROT INDICATORS
Yellow LEDs lit for a few seconds during the switch-on phase (initial diagnosis) or in the presence
of direct voltage, radio disturbance, subsonic frequencies or also when an overcurrent situation is
detected (usually due to a short circuit on the outputs of the amplifier or a too low loudspeaker
impedance). When the protection function is triggered, the amplifier goes into mute status. The
system automatically resets as soon as the problem is resolved.
7. INDICATION OF THERMAL PROTECTION - PEAK LIMITER - MUTE / PROT
The combination of the red and yellow LEDs lit at the same time indicates that an excessively
high temperature has been reached. When the protection function is triggered, the amplifier
remains in mute status until the normal operating temperature is restored.
8. AIR INTAKE GRILLE
It allows amplifier cooling. Do not obstruct its access and clean it when necessary.
