Operation
The amplifier’s On/Off Switch is a
When using the remote On/Off function, the main On/Off switch must remain in the On position. See page 11 for more information on remote On/Off connections.
NOTE: The power switch does NOT isolate the appliance from mains. Make sure the mains power socket or an alternative disconnect device is near by and easily accessible. When the amp is connected to mains, the
2 Channel (Stereo) Mode
In this mode, the amplifier’s two channels operate fully independent of each other. Each signal enters the unit and is amplified separately.
Parallel-Mono Mode
In this mode, a single input signal (connected to channel 1) is connected to the two output channels. The output terminals of the two channels are configured in parallel using an internal relay. The (single) load is connected either to the output of channel 1 or to that of channel 2 (as if in stereo). While the total output of the amplifier remains the same and the output voltage level is also the same as in stereo operation, the minimum impedance that can be connected is reduced by half because the current capability is doubled. Only the Channel 1 attenuator is active. The Channel 2 attenuator should be turned down to zero. This mode is useful when identical loudspeakers are to be operated with the same power.
IMPORTANT: When connecting speaker cabinets in parallel, always use all the contacts in both SPEAKON connectors. If not, this can cause permanent damage to the connectors and considerably reduce performance.
Bridged Mono Mode
In this mode, a single input (connected to channel 1) is connected to the two output channels that have been ‘Bridged” together. Each output channel processes the signal, but the polarity of channel 2 is reversed. The (single) load is connected between the two positive channel outputs using a suitably connected SPEAKON connector. While the total output of the amplifier remains the same, both the available output voltage and the minimum impedance that can be connected are doubled, as compared with stereo operation. Only Channel 1 is active. A signal feeding Channel 2 will have no effect on the output.
