XA160.5 Owner’s Manual
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
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
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
