BALANCED INPUT

The input is in the form of Balanced Neutrik XLR connectors

• Interference:

If the unit is to be used where it maybe exposed to high

levels of disturbance such as found close to a TV or radio

transmitter, we advise that the unit is operated in a

balanced configuration. The screens of the signal cables

should be connected to the chassis connection on the

XLR connector as opposed to connecting to pin1. The

CPA-50 conforms to the EMC standards.

• Ground Loops:

If ground loop problems are encountered, never disconnect the mains earth,

but instead, try disconnecting the signal screen on one end of each of the

cables connecting the outputs of the CPA-50 to the patchbay. If such measures

are necessary, balanced operation is recommended.

SPEAKER OUTPUTS L-/L+/R-/R+

The speaker outputs connectors are in the form of binding posts that can be wired

directly to the speaker terminals via bare wires through the hole and tightened, via

spade terminals, or via banana plugs.*

The diagrams on the following pages show some common wiring methods. Note

that when in bridged mono mode the R

provides the positive, the other terminals are not used. (See

Due to European legislation the use of banana plugs is not permitted. Banana plugs should only be used

in the USA and Canada.

POWER

The mains inlet, I.E.C., which also incorporates the internal mains fuse, can be

found on the rear of the unit. If a fuse should need replacing see section 'Power

Connection'. A mains lead will have been provided with the CPA-50 to suit the

mains configuration for the country of your purchase. Please use this cable.

The power switch is a hard boot switch (as opposed to a soft stand-by switch) and

so when in the off position the CPA-50 will draw no mains power.
