INT-30A Owners Manual

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.

If you have purchased this amplifier, we thank you for your confidence, and hope that you enjoy it for many years. If you need product service, 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-30A at the white binding post which is marked “Signal Gnd”.
