XA60.5 Owner’s Manual

So the amplifier is sitting there unconnected.

Make sure that the rear panel power switch/breaker is off (down). Plug the AC cord into the back of the amplifier, and then into the wall. Then turn the power switch/breaker on (up). The lights in your house will dim for a moment as the power supply charges the capacitors.

If your amplifier uses a circuit breaker and not a fuse, please note that this circuit breaker is not a “safety device” or “emergency disconnect” for this product. It will provide current limiting which will protect the amplifier, but it does not provide personal shock protection in the manner of a ground-fault interrupter. One more reason why it is important not to defeat the Earth connection of your power cord.

On the front panel, the “Standby” LED indicator should be glowing blue, indicating that AC power is available and the capacitor banks are charged. If the “Power” LEDs are lighting the meter, use the front panel stand-by button to go to stand-by mode.

Now turn off the rear power switch and unplug the AC power cord from the wall while you connect the speakers and inputs.

Check to make certain that the loudspeaker cables aren’t shorted at the loudspeaker end, connect speaker cables to the output binding posts on the amplifiers, observing correct polarity. The output binding posts will accept either bare wire or spades. (Regulatory agencies in many countries have banned binding posts that will accept a banana plug, forcing us to abandon this option.) Make sure that your speaker wires only attach to the outputs of the amplifier, not to each other and never to the amplifier case.

Remember the warning about treating the output connections as ground, particularly if you are using a powered subwoofer with this amplifier. If you need a ground, use the one provided specifically on the rear panel of the amplifier.

The amplifier may be driven single-end or balanced, your choice. Single-ended input will always occur through the RCA connector and balanced input will always occur through the XLR connector.

Again, if you drive the amplifier single-ended then leave the supplied jumpers in place between pins 1 & 3 on the input XLR.

On the XLR connector pin 1 is ground, pin two is positive input and pin 3 is inverted (negative) input. Pin numbers are marked on the
