WIRING
Connect the speaker cable to the speaker cable terminals, matching the proper polarity with your amplifier, + to + (red) and - to - (black). Make sure
to connect the right channel to the right speaker and the left channel to the left speaker . Either channel may be attached to either terminals set,
however, be sure that polarity ( + and - ) is correct on each channel or the performance of the speaker will be seriously affected as one channel will
cancel out the other.
70 Volts consideration (Applicable to only 70V tap speakers)
The 70V transformer offers you the ability to daisy chain multiple
number of speakers in series. In doing so, you would simply connect
1 pair of outputs to each speaker and daisy chain to subsequential
speaker/s. If you don’t intend to daisy chain the speakers, set the
default setting to 8 ohms. (See Diagram 3)
