1. Introduction

These four models are integrated amplifi ers of 30, 60, 120 and 240W respectively, designed for use in all kinds of
fi xed public address systems that broadcast emergency announcements and background music for offi ces, restaurants,
churches, etc.
The amplifi ers have thermal protection to avoid failures due to overheating. The protection system is reinforced by
fuses.
As a general rule, it is recommended that no operation should be performed on the inside of the amplifi er, the connectors
or the terminals, when the amplifi er is connected to the AC or DC supply.
These amplifi ers have been designed to meet Electrical Safety and Electromagnetic Compatibility standards.

1. Microphone tone control: Acts on the MICRO inputs.
By turning the potentiometer towards the right, a
fl at response is obtained; by turning it towards the
left, low frequencies are decreased, and so it is easy
to obtain optimum voice equalisation.

7. BASS control: Varies the signal level of the AUX inputs
at low frequencies. By turning the potentiometer to
the left, the bass is decreased by 10 dB. In the
central position a fl at response is obtained. By
