Installation
Locate the Amplifier as close as possible to its final installation point. Allow access to the rear panel
for making connections.
The Monoblock Amplifier is convection cooled, eliminating the need for fan or forced air cooling.
When operating, the chassis should have at least five (5) cm (2 inches) of air space around the
heatsink areas.
Front & Rear Panel Function Controls
Before attempting any system interconnection, please familiarize yourself with the front and rear panel
controls of the Monoblock Amplifier. The descriptions below refer to the numbers and letters
