Operation Manual

21
In case the total loudspeakerpower exceeds the amplifier's power, use the 70 volt out-
put; it is now allowed to connect loudspeakers up to twice the amplifier power.
When the 25V output is used, it is allowed to connect loudspeakers up to 4 times the
amplifier power
As a rule of thumb, loudspeaker transformers are provided
with several power terminals obtaining a larger flexability;
use the low power terminal where less volume is required
and use the high power terminal where more volume is
requlred.
It is allowed to provide individual loudspeakers with an on/off switch or with a rotary
switch (with connections to several terminals) to obtain a kind of volume control.
WHEN USING THE 25, 70 OR 100 VOLTS LOUDSPEAKER SYSTEM, THE SAME
RULES SHOULD BE APPllED AS ARE VALID FOR THE 230 VOLTS MAINS SUP-
