# 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.&#x20;
* 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.

* 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

<div align="center"><figure><img src="/files/EW5Vjn52Nfu9fQd59Wtj" alt="" width="344"><figcaption></figcaption></figure></div>

* 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.&#x20;
* 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

## Heat management and dissipation

### X1 array

<figure><img src="/files/Em3ZklS87NFmd3OnqLh4" alt="" width="336"><figcaption></figcaption></figure>

All power used by a loudspeaker system is eventually converted to heat dissipated by amplifiers and drivers.&#x20;

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

* Electronics packages are actively cooled by 8 temperature-controlled fans.&#x20;
* 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.
