You can use the 559 as a mono power amplifier, to obtain more
than three times the power output, by wiring it in bridge mode.
● Switch the BRIDGE MODE switch to the ON position.
● Fit the supplied bridge mode link between the left and right
negative terminals.
● Connect the audio inputs to the BALANCED or
UNBALANCED BRIDGE MODE input, as appropriate.
● Connect the loudspeaker between the BRIDGE MODE
terminals.
You can bi-wire in bridge mode by using the other pair of
BRIDGE MODE terminals to connect separately to the
loudspeaker treble unit.
