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.

WARNING! In Mono-Bridge mode RMS output voltages as high as 230 V. Wiring to

the speaker loads must conform to NEC Class 3 safety standards or its equivalent. All

customer specific cables should only be manufactured by qualified personnel.

WARNING! Terminals marked with

these terminals/connectors requires installation by trained personnel, or pre-

manufactured cables.
