Power

• HOLOPLOT recommends Amphenol HP series 25 AC power cables, rated at 25A, to provide AC power to Audio Modules.

• The Audio Modules can operate safely and with no audio discontinuity when the AC voltage stays within a nominal range of 115 - 240 V at 50 or 60 Hz

• Intelligent AC power supply automatically detects and selects the correct operating voltage

• MD80-S requires power for the electronics package and subwoofer

Power connectors

• The blue AC Power IN connector supplies power to the Audio Module.

• The grey AC Power OUT connector allows two Audio Modules to be looped and powered from a single power source for operating voltages ≥ 208 V.

MD96

• The Audio Module connector panel includes two Amphenol HP Series 25 connectors, one for AC Power IN (blue), and one for AC Power OUT (grey).

• The 3-conductor Amphenol HP Series 25 is rated at 25 A and uses a locking connector that prevents accidental disconnections.

MD80-S

• The power connectors on MD80-S are found at two locations: The electronics package and the loudspeaker cabinet.

• The Audio Module connector panel includes two Amphenol HP Series 25 connectors, one for AC Power IN (blue), and one for AC Power OUT (grey). The 3-conductor Amphenol HP Series 25 is rated at 25 A and uses a locking connector that prevents accidental disconnections.

• The blue AC Power IN connector supplies power to the Audio Module.

• The grey AC Power OUT connector allows it to loop through to either the subwoofer Amplifier of the MD80-S or to another Audio Module for operating voltages≥ 208 V from a single power source.

Power connectors on loudspeaker cabinet

The connector panel on the MD80-S Loudspeaker Cabinet includes a single Amphenol HP Series 25 connector: an AC Power IN (blue) supplying power to the subwoofer amplifier Module.

Heat management and dissipation

X1 array

All power used by a loudspeaker system is eventually converted to heat dissipated by amplifiers and drivers.

Acoustic power is absorbed and converted to heat by air and acoustic materials

• Electronics packages are actively cooled by 8 temperature-controlled fans.

• The back of the Audio Module must have access to cool air

• No seal from surrounding infrastructure

• 100mm clearance required from the back of a module

When playing audio, heat is dissipated with a 60/40 front/back spread.

In Sleep and Idle modes, all heat is dissipated towards the back of the Audio Module.
