Installation - dB Technologies HPA Serie Bedienungsanleitung

3. INSTALLATION

3.1 STEREO configuration
Place the MODE switch in STEREO position using both audio inputs and relevant
volume controls (FIG. 1, for output connection FIG.A).
3.2 BRIDGE configuration
Place the MODE switch in BRIDGE position using only audio input CH1. The CH1
volume control will control total output volume (FIG. 2). Take the output signal only from
connector CH1( output connection in FIG.B).
3.3 MONO configuration
Place the MODE switch on the back of the amplifier in MONO position and use only
audio input CH1. The CH1 volume control will control the volume of both channels
(FIG.3).
This configuration is especially suitable for connecting up several speakers piloted by
the same signal ( for output connection FIG.A)
3.4 Installation notes
The HPA series amplifiers are designed to be housed in standard 19" racks. The models
occupy 2 units. If the amplifier is installed inside a 19" rack, we recommend to use the
mounting facilities provided at the rear of the amplifier to prevent the front panel from
having to bear the entire weight of the equipment.
Make sure that sufficient ventilation is provided to allow the amplifier to cool correctly.
Do not obstruct the rear part of the amplifier as this would prevent correct air flow.
3.5 Connection to the mains power supply
The amplifier must be connected to a power mains able to supply at least the maximum
power output required. Do not use extensions or reductions which could compromise
the correct supply of current.
3.6 Cooling
The cooling is governed by a circuit which automatically regulates the speed of the fan in
relation to rises in temperature. This way, noise from the fan is reduced to the minimum.
Ventilation is forced and the air flow is from the front to the rear.
