OUTPUT
Maintain proper polarity on the output connectors.
Output channel: connect the output EURO block terminals to the loudspeaker loads. Use
terminals marked ‹ 4Ω › for a 4Ohm loudspeaker load, or use terminals marked 70V or 100V and
COM for constant-voltage loudspeaker loads.
Connect the COM terminal to the negative (-) speaker lead; connect one of the other terminals to
the positive (+) speaker lead.
Impedance and output voltage are shown below:
CPA12
4Ω / 22V 41Ω / 70V 83Ω / 100V
CPA24
4Ω / 31V 21Ω / 70V 41Ω / 100V
CPA36
4Ω / 38V 13.6Ω / 70V 27.8Ω / 100V
The impedances in the above table represent the total speaker system impedances.
