Mode Select Switch STEREO MODE
If you connect one or two pairs of speakers to the amplifier, pleace the switch in the "STEREO" position.
Note: For playing 2 pairs of speakers (A plus B), make sure each speaker has an impedance of 8ohm or greater.
BRIDGE MODE
When set to "Bridge" mode, the amplifier is a signal channel mono amplifier.
For bridge mode, playing right and left together as mono output, plug RCA cables in to Right and Left at main input.
High-level inputs
For the use of a 2.1 configuration, the "high level speaker" inputs are used to connect an external stereo amplifier and a pair of stereo speakers to these terminals.
The external amplifier manages the stereo speakers. The amplifier A 1000 supplies the subwoofer and allows the DSP management.
