SET UP

X amplifiers run at about the same power as their output rating, and

XA amplifier run more than twice that. The heat sinks on the side

of the amplifier run hot to the touch – about 25 to 30 degrees C.

above ambient, so you can expect 50 to 55 degrees C. temperatures

on the heat sinks. It is very important to the long life of the

amplifier that they get good ventilation.

You can put this amplifier anywhere you want, but it must have good

ventilation. Do not place 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. You should have a minimum of about 6 inches clearance to

the top and sides for adequate air circulation.

When not actually intending to play music the amplifier should be

left in standby mode, where it draws only a few watts of bias on

the output stage. If you wish to reduce the power draw to 0, you

can shut the amplifier off via the rear panel switch, however we

recommend that for minimum noise this switch should be toggled in

stand-by mode.

We have provided a standard IEC power cord that fits into the

standard 15 amp IEC receptacle at the rear of the amplifier chassis.

With the exception of the largest of the X and XA series, there is no

difficulty running two amplifiers on a single 15-amp circuit. Given

the high current draw, we generally do not recommend active line

conditioners, although they are unlikely to damage the amplifier.

This amplifier is equipped for operation with an earth ground

provided by the users AC outlet. Never defeat this ground

connection. The signal ground of this amplifier is connected to

earth through a power thermistor, which provides a safety ground

but provides isolation from system ground loops.

For maximum safety we suggest that the power cord should be the

last cable installed on your power-amplifier. You may, if you wish,

substitute a 15-amp aftermarket power cord for the one we have

supplied. Only use power cords, which meet all local safety standards

and carry acceptance marks from the local regulatory authority. The

power cord should be attached to the amplifier prior to plugging

into house power. Place the rear mounted switch in the off (down)

position before plugging in this amplifier.
