5. LOUDSPEAKER CONNECTION
Attention
To avoid the risk of electric shocks, never touch the amplifier outputs when they are operating.
The device can be used with loudspeakers having constant impedance (4Ω) as well as constant voltage (70V, 100V).
Keep the following instructions in mind when carrying out connections.
Constant impedance line:
Connect the constant impedance line (4Ω) between the “COM” and “4Ω” terminals (Fig. 2, Ref. 4) .

To ensure maximum performance, total impedance of the loudspeakers connected to the line must be equivalent to
the output impedance of the amplifier.

The total power of the diffusers must not be less than the output power of the amplifier.

It is advisable to minimise the length of connection, and anyhow increase the cable section according to the
distance covered.
Constant voltage line:
Connection to 100V or 70V
Connect the constant voltage line (100V or 70V) between the “COM” and “100V” (or “70V”) terminals (Fig. 2, Ref. 4) .

The loudspeakers must be supplied with a transformer having an input voltage equivalent to that of the amplifier.

The total power of the loudspeakers must not exceed the maximum output power of the amplifier.
