4. Installation

The installation and equipment rack should be configured to
provide appropriate ventilation airflow space around the front and
rear of the amplifier as illustrated Diagram 1b. A ventilation airflow
space of at least 25 mm (1 inch) should be maintained along at
least one side of the amplifier at all times. Ventilation apertures
are located on the rear panel of the amplifier and must not be
obstructed. It is important to retain at least 80 mm (3. 1 inch) free
space for airflow behind the amplifier rear panel.
The amplifier works in a 0°C~40 environment. Airflow goes from
the front of the amplifier (ventilation holes) through the rear panel
to ensure effective heat dissipation. Please ensure that the air can
flow from the front to rear panels.
Note: If the internal temperature exceeds 85 degrees C, the output
voltage will be reduced, to avoid excessive temperature rise. If the
temperature continues to rise to 90 degrees C, the power amplifier
will shut down. Once the temperature has dropped to a safe
temperature, the amplifier will restart automatically.

Maintenance
