7. Output Connectors

This is a five-position barrier strip for connection of speaker 

loads. Each terminal accepts bare wire from 22 AWG 

to 10 AWG, or spade lugs sized for the same range of 

conductors.

Terminals are provided for 4 ohm low-impedance loads or 

25, 70 and 100 Volt high-impedance loads.

All outputs with the exception of the 4 ohm output are 

transformer isolated.

  LOW IMPEDANCE

To connect a speaker directly, connect the lower GND 

terminal to the negative post of your speaker, and connect 

the 4 ohm terminal to the positive post. 

Make sure that your average speaker impedance is not less 

than 4 ohm, 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.

  HIGH IMPEDANCE

If you are using a constant-voltage distributed speaker 

system, connect either the 25 V, 70 V, or 100 V output 

terminal to the "+" side of the speaker system, and connect 

the upper "GND" output terminal to the "–" side of the 

speaker system.

The voltage of your speakers must equal the voltage of the 

amplifier's output terminal ( 25 V, 70 V, or 100 V).

CAUTION:

 Make sure that you do not overload the 

amplifier. This may cause overheating to the amplifier, and 

possible damage to your speakers. To avoid overloading, 

make sure that the taps on the speakers add up to no more 

than 80% of the rated power of the amplifier being used 

(CAM160: 128 watts, CAM80: 64 watts). For example, for 

the CAM160, you could use a maximum of 12 speakers 

with 10 watt taps (12x10 = 120 watts). For further 

protection, use these figures as the maximum power sum 

of all the speaker taps: CAM160: 100 watts, CAM80 50 

watts.

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 25 V, 70 V, and 

100 V terminals of the amplifier using the protective cover 

supplied.

GND and 25V are used to connect a string of 25V speakers. 

Use Class II wiring:

GND and 70V are used to connect 70V speakers.
