Constant-voltage output mode, connect the amplier in bridge mode, put the “POWER OUT SELECT” to
the right, then connect 70V/100V in wall/ in ceiling speakers to the“70V/100V MONO OUTPUT” in series,
the total power of speaker should be below 500W
Fixed resistance output mode, connect the amplier in stereo mode, put the“POWER OUT
SELECT” to the left, connect 2 8ohm speakers to the“8 Ohm Stereo Output” as above.
