Connecting the RM/RS

The MEON LiFe can be used in conjunction with Remote

Audio's RM (Remote Meter) or RS (Remote Switch). The

RM allows remote monitoring of voltage and current (Amps)

as well as remote ON/OFF control of the MEON LiFe. The

RS provides remote ON/OFF control and a low voltage

indicator. Connect either device's 6-pin connector via the

"Remote" port on the connector panel of the MEON LiFe.
See the RM and RS user guides for more details.

Does the MEON LiFe use fans?

No. The MEON LiFe was designed to employ convection

cooling specifically because cooling fans cannot be tolerated

on a very quiet sound stage. It is best to mount the MEON

LiFe with some free space above the chassis to allow proper

cooling when using AC power. The MEON LiFe has vent

slots in the sides of the chassis that should remain

unrestricted during operation to facilitate cooling while

supplying maximum rated current.

Noise and Shared Power Systems

It is possible to have unwanted audible noise through a

common (shared) power source typically due to “ground

loops” from the various internal power supplies of the

devices being powered. 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:

Important Information about Internal Battery Protection

In addition to the resettable circuit breakers on each output,

the MEON LiFe’s battery is internally protected from

overload and short circuits. In some cases, a sudden dead

short at an output may activate the protection circuit of the

internal battery. In this condition, the MEON LiFe will not

come back on until external power is applied, either by

plugging into AC or, if AC is not available, by applying a

charged 12V battery to the external battery input.

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 the one made by Lectrosonics.

4) Use a power isolator cable such as the Remote Audio Juicer

cable.
