STEREO : Channel A and Channel B work independently of each other. In this mode, the amp functions as a stan-
dard power amplifier.
BTL : Channel A and Channel B are bridged internally, creating a 300 watt (8 ohms) mono power amplifier.

7. Cooling Fan/Air Vent
This comprises a forced-air cooling fan in combination with air vents. Cooler air is drawn in through the intakes in
the top and bottom panels, and the air heated by the amp is expelled through the vents.
The fan is activated whenever the temperature of the interior heat sinks exceeds 60 ˚C, and the rotation speed of the
fan changes smoothly in response to any change in the temperature.
* To ensure adequate cooling capacity, position the amp so that both intake and exhaust vents remain unblocked.
