satisfaction audio product. From a measured and subjective viewpoint this
is an outstanding product, we trust you will sit back and listen with a big
grin on your face.

have any questions or comments, or if we can help you with your audio
system, please don’t hesitate to contact us.
X topology amplifiers run at about the same power as their output rating,
and a large part of that energy gets dissipated across the heat sinks. Expect
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 wish, but it must have good
ventilation to properly cool. Do not place this product 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. Never block any ventilation
openings in the chassis. Never expose this product or it’s remote control
to excessive heat sources, such as domestic heaters or open fires. Keep all
electrical devices away from liquids, and liquids away from electrical devices.
When not actually intending to play music the amplifier should be left
in standby mode from the front panel switch, 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 at the loudspeaker this switch should
be toggled in stand-by mode, only. If you are not going to use this product
for an extended period of time or if you are expecting an atmospheric
electrical disturbance (lightening storm) un-plug it. We have provided a
standard IEC polarized power cord that fits into the standard 15 amp IEC
receptacle at the rear of the amplifier chassis.
Given the character of these amplifiers current draw, we generally do not
recommend active line conditioners, although they are unlikely to damage
the amplifier. Save your line conditioner for the low level components, like
your cd player.
This amplifier is equipped for operation with an earth ground provided by
the users AC outlet. Never defeat this ground connection or the polarized
plug of the power cord. 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. Should your audio system
have a device that requires an additional signal ground you will find that
ground on the rear of the INT-150 at the white binding post which is
marked “Signal Gnd”.
