Two fullrange speakers connected in stereo
mode
One speaker connected in mono bridge mode
NOTE!
4 ohm minimum load when using bridge mode
connection. Lower impedances may damage the
amplifier. In bridge mode the amplifier sees a 4
ohm load as 2 ohm.
Bridge mode can be used to connect a center
channel speaker.
You can also run a front system in bridge mode
using two RA25 amplifiers, one for each channel.
If you want to use the RA25 for bridge mode
connection of a subwoofer, you must use an
external passive lowpass crossover.

Speaker wiring RA25
RA25 is a 2-channel stereo amplifier. It can be
connected either as a stereo amplifier for fullrange
speakers, or as a mono amplifier for a single driver
connected in bridge mode.
RA25
With the HP-filter in OUT position the amplifier
allows the speakers to play fullrange. If you for
some reason want to limit the low bass
reproduction switch IN the HP-filter. The typical
setting is then around 60 – 80 Hz.
