AUDAC SMA Series - Connection Examples

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 amplier outputs, merging both of them
which results in double output power to one single load. In this conguration, the load is connected using a
two-core loudspeaker cable between the + terminals of both channels. When using speaker connectors,
connections are made between +1 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 conguration by the user interface which is
controllable using the front panel controls.
