FRONT PANEL
1) Tone controls: BASS (100 Hz ± 10 dB); TREBLE (10 kHz ± 10 dB).
When using the amplifier connected to horn speakers without protective capacitor, we
recommend you significantly attenuate the low frequencies (BASS control) to limit the
excursion and heat dissipation of transducers.
2) Output level master control.
3) Output level display (5 LEDs) and power (ON LED).
The amplifier works at nominal power when the LED relevant to the max level flashes.
4) Power switch.
REAR PANEL
1) Audio input XLR connector.
2) Audio input screw terminals.
3) Audio input “Phantom” power supply switch (+21 V dc; for instance, necessary when using
an electret microphone).
When pressed down, this pushbutton enables the phantom power supply.
4) Audio input mic. / line sensibility switch. When this pushbutton is released, the input is set for
the connection (at high sensitivity) of a microphone; when it is pressed down, the input is set
for the use of a high level signal (e.g. CD / cassette players, tuners, etc.).
5) Outputs to loudspeakers (100 / 70 V constant voltage; low impedance 4 Ω).
6) Input for 24 V direct current power supply. The amplifier does not include a battery recharging
device and it is not able to keep charged batteries connected.
7) Amplifier earth terminal.
8) Connector with fuse for the power supply cable (from mains)
Note: the type of fuse to be used is specified on the rear panel.
