The MTR-500 70V/100V Line Matching Transformer Combiner enables the conversion from an 8 Ohm
amplifier output to a 70V/100V. This unit is ideal for both professional stage or PA applications which
require running multiple pairs of speakers to a single amplifier.

Constant-voltage output mode, connect the amplifier 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 amplifier in stereo mode, put the “POWER OUT
SELECT” to the left, connect 2 8ohm speakers to the “8 Ohm Stereo Output” as above.
