XLR Outputs

The Meon LiFe provides 12VDC power to ten 4-pin XLR outputs. Three outputs are rated to 9A and the remaining seven are rated to 5A. Each output has built-in overload and short-circuit protection.


USB Power

Since smartphones and tablets have become ubiquitous on set, the Meon LiFe is equipped with two 5VDC USB charging ports on the front panel. These ports are capable of providing up to 2A of charging current and are optimized to quickly charge Apple devices.

 

Internal Battery Backup

If AC power is ever interrupted, the Meon LiFe seamlessly switches to its internal 20 Amp-hour Lithium Iron Phosphate (LiFePO4) battery. This relatively new battery technology makes the Meon LiFe smaller, lighter and more stable than previous cart power systems.

 

 

 

 

Supplemental Batteries

External lead-acid batteries or Extra LiFe battery packs can be connected to the Meon LiFe to increase the battery run time of the system. The three-stage internal battery charger automatically charges these batteries whenever AC power is present.


 

Monitoring

The illuminated voltmeter on the front panel gives you constant feedback of the voltage present at the output connectors. The charge status LED indicates when the batteries are fast charging (red), topping (flashing green) or fully charged (solid green). When the Meon LiFe is off, pressing the Test button will display the voltage of the battery.

 

 

 

 

Flexible Rack Mounting

The removable rack ears can be used to mount the Meon LiFe in a variety of different configurations. Mirrored, illuminated front and rear power switches allow you to power the unit on or off from either side.

 

 

 

Remote Port

The Meon LiFe also comes equipped with a Remote Port to connect an RM or RS (sold separately).

FAQ

Noise and Shared Power Systems

It is possible to have unwanted audible noise induced into audio systems by a common (shared) power source. To optimize your system, it is recommended to use line level signals instead of mic level signals whenever practical. Also, turn phantom voltage off of all preamp inputs that are connected to non-microphone devices. If noise is still heard, unplug one device at a time from the Meon, noticing any change in noise associated with the removal of each device. If the noise goes away after unplugging a particular device, try powering that device with a separate battery. If using a separate battery causes the noise to go away, then the problem is a ground loop associated with the combination of a common power source and audio grounding schemes. Be aware that this noise will not be removed with “LC” filters found in some cart power supplies.

To remove the noise, here are four options for interrupting the ground loop:

  1. Use a separate battery for the offending device.
  2. Try different grounding/floating schemes with the audio cables.
  3. In devices that use a single 9V battery, use an isolating 9V battery eliminator such as those made by Lectrosonics.
  4. Use a power isolator cable such as the Remote Audio Juicer cable.

Does the Meon LiFe use fans?

No. The Meon LiFe was designed to use convection cooling since it’s primary function is powering sound recording equipment on sets. Even the slightest hum of cooling fans cannot be tolerated on a very quiet sound stage.

When using AC power, it is best to mount the Meon LiFe with some free space above the chassis to allow proper cooling. The Meon LiFe has vent slots in the sides of it’s chassis which must remain unrestricted during operation to further facilitate cooling.
