Power Tap Selection
16-ohm or 70V
The Power Tap selector switch is used to set the
appropriate power level or impedance for your
system. Rotate the switch until the power level
you require lines up with arrow.
IMPORTANT:
When connecting to a 70V amplifier,
make sure that the MPS1 Tap Selector switch
IS NOT set in the “16Ω” position.
Speaker Connection and Polarity
Speaker wiring is terminated at a snap-lock input
connector, with a positive and negative terminal.
All wiring should be done prior to installation and
then plugged into the rear of the MPS1. Wire all
speaker polarities the same way.
70V System Configurations
When designing a 70V system, the total of all power tap settings of all the connected
speakers CANNOT EXCEED the output power of the 70V amplifier (amplifier power
can exceed the sum of the speaker loads).
Low-Impedance System Configurations
When wiring together multiple MPS1 speakers that are set to 16 ohms, it is important to
calculate (using Ohmʼs Law) the total load that these speakers present to the amplifier.
The total load impedance of the interconnected speakers cannot be lower than the
minimum load impedance rating of the low-impedance amplifier. Also, care must be
taken to ensure the amplifier cannot overdrive the speakerʼs maximum power rating.

EXAMPLE:
16 + 32 + 8 + 8 + 16 = 80 Watts minimum amplifier output rating.
EXAMPLE:
Four 16 -ohm speakers in parallel = 4 ohms. Also in this example,
the maximum amplifier output power rating should not exceed 200W (4 X 50W,
the MPS1 max. power is 50W).
