t
he balanced connection is always preferable
,
especially with cables longer than

.
If necessary, short the '–' and 'ground' contacts to get an unbalanced connection:
+ signal
– // GND ground

Amplifier output to loudspeakers (terminal strip), available as:
-
100 / 70 V constant voltage line
-
Low impedance (min. 4
Ω
).
Use 1 output only (see the manual section 'Loudspeaker connection').
Max. output power is 120 W.
9
Input for the secondary 24 V dc power supply (batteries), necessary to ensure the
amplifier operation even if the mains supply is unavailable.
Make sure the connection po / – is correct and use a cable having wires with a
suitable section (at least: 2.5 mm²).
