Bogen MPS1W Power Tap Selection, Speaker Connection and Polarity, 70V System Configurations

Power Tap Selection

16-ohm or 70V

POWER TAP SELECTOR SWITCH

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).

EXAMPLE: 16 + 32 + 8 + 8 + 16 = 80 Watts minimum amplifier output rating.

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: 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).
