OUTPUT TERMINALS (12 and 13):
This terminal block is normally covered by a protective
cover. Remove the two screws and the cover while making
or undoing connections. Securely refit the cover when you
have finished making the connections.
The five output terminals are labeled COM, 4
Ω
, COM,
70 V, and 100 V.
12. LOW IMPEDANCE
To connect a speaker directly,
connect the COM terminal
to the negative post of your
speaker, and connect the 4
Ω
terminal to the positive post.
Make sure that your average
speaker impedance is not
less than 4
Ω
, as this may
overload the amplifier.
The speaker output connectors are screw terminals. Use
16 or 18 gauge wire for connecting the amplifier outputs to
the speakers. Strip the wire back about 3/8" inch, loosen
the screw enough to loop the wire around the shaft of
the screw (clockwise), and tighten down the screw with a
screwdriver.
13. CONSTANT VOLTAGE
If you are using a constant-voltage distributed speaker
system, connect either the 70 V, or 100 V output terminal to
the "+" side of the speaker system, and connect the "COM"
output terminal to the "–" side of the speaker system.
Each speaker must be equipped with a line transformer
with an input voltage equal to that of the line (70 V or
100 V).
Make sure that the sum of the power capacities of the
speakers does not exceed 90% of the amplifier's rated
output power (216 W).
CAUTION:
To prevent the risk of electric shock,
never touch the bare wires coming from the OUTPUT
TERMINALS of the amplifier when it is switched on.
When the connections have been made, insulate the
70 V and 100 V terminals of the amplifier using the
protective cover supplied.
COM and 70 V are used to connect 70 V speakers.
Use Class I wiring:
COM and 100V are used to connect 100V speakers
