CXA240 – 7
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 ret the cover when you
have nished making the connections.
The ve 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 amplier.
The speaker output connectors are screw terminals. Use
16 or 18 gauge wire for connecting the amplier 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 amplier'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 amplier when it is switched on.
When the connections have been made, insulate the
70 V and 100 V terminals of the amplier 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
