5. Connection
Decide where the appliance is to be physically installed – it can be used free-standing or
mounted in a standard 19" rack requiring two rack spaces. When installed, makes sure
that both the front and the rear panels are unobstructed and that there is good
ventilation around the entire unit.
Before switching on the appliance, make sure the appliance is switched off and the
volume controls are at their minimum position. It is never a good idea to power up any
amplifier that is not connected to loudspeakers.
Use the correct connectors to connect the appliance to the loudspeakers and sound
system.
6. Using the Bridging Output
When the switch is placed in the STEREO position, the appliance functions as a true
stereo amplifier, where both channels (1 and 2) can receive different input signals and
produce independent output signals.
When the switch is placed in the BRIDGE position, channel 1 is routed to both power
amplifiers bridged together, producing a single output signal.
In BRIDGE mode, connect the red (+) terminal of channel 1 to the positive input of your
loudspeaker, and the red (+) terminal of channel 2 to the negative input of your
loudspeaker. Do not use the black (-) output terminals of either channel.
When using the amplifier in BRIDGE mode, please make sure that your speaker
impedance is greater than or equal to 8 Ω.
