Setup

X600.5 Owners Manual

You can position this amplifier most anywhere you wish, but it re- quires adequate ventilation. We do not recommend placing it in enclosed cabinets or small closets without means for air to circulate freely. Stacking these power amplifiers directly upon each other is not recommended for the same reason. This amplifier idles at about 550 watts, most of which dissipates as heat across the heatsinks. As a point of reference, these heatsinks should never become too hot to touch for several seconds.

Let’s talk about AC power requirements. This amplifier draws about 5 amps (continuous rms) at 120 volts out of the wall during normal operation, and this power draw reflects mostly the idle current that we run through the output stage. If you are driving a low impedance load, you will draw more power than this, but this will not be typical.

The amplifier’s voltage and current rating are indicated on the rear panel. It will be 240 volts, 220 volts, 120 volts or 100 volts, all with an appropriate rear mounted resetable circuit breaker. The frequency rating of the AC line source in all instances will be 50 to 60 Hz. Please verify that the amplifiers indicated voltage requirements are consistent with the line voltage supplied at your location.

The Pass Laboratories™ X600.5 is provided with a conventional IEC detachable AC line cord, which is rated at 15 amps. The safety ground is attached to the chassis in the conventional approved manner. The AC power input to the amplifier runs through a RF filter, which re- moves high frequency noise coming into and going out of the ampli- fier power supply.

Under no circumstances should you defeat the ground connection of the power cord. For your safety, the chassis of the amplifier should be earth grounded. Signal ground is isolated from chassis, safety ground, to reduce the incidence of ground loop noise. The presence of a safety ground will not degrade the audio signal chain.

You may substitute an aftermarket detachable IEC 320 style power cord of your choosing; provided it is rated for at least 15 amps and it meets all legal requirements and has been approved by the local testing authority for such things.

Looking at the rear panel you will see the IEC 320 AC power cord receptacle, a thermal magnetic breaker switch, two pairs of output connectors, a pair of binding post connectors for remote turn-on, one RCA input connector and one XLR balanced input connector.

Make sure that the breaker switch is off (down). Plug the AC cord
