SMA&SMQ - User manual 017
Normal operation mode:
This is the most common mode whereby every channel is driven with a separate signal and a loudspeaker
is connected to each of them. The loudspeakers are connected using a two-core loudspeaker cable (or one
four-core loudspeaker cable for two subsequent channels) to the corresponding terminals (+1/-1 for speaker
connectors and +/- for terminal block connectors).
Bridged mono mode
In bridged mono mode, one single load is connected between two amplifier outputs, merging both of them
which results in double output power to one single load. In this configuration, the load is connected using a
two-core loudspeaker cable between the + terminals of both channels. When using speaker connectors,
connections are made b1 and +2 terminals of the channel 1 (or channel 3 for SMQ). When using
terminal blocks, connections are made between both + terminals.
Selection for bridged output channels is made through software configuration by the user interface which is
controllable using the front panel controls.
