sonifex cm ms3 1

The Sonifex CM-MS3 is a passive “one-to-three” splitter housed in a small but robust aluminium box. It is designed to split a single microphone or line source to up to three destinations, using Neutrik XLR connectors.

Wide Signal Range Capability

The CM-MS3 uses high quality audio transformers that are capable of accepting input levels up to +18dBu, making the splitter useful in both microphone and line level splitting applications.

Versatile Phantom Powering Options

The CM-MS3 offers three methods of providing phantom power to a microphone connected to its input:

  • From the external +48VDC power connector.
  • From a microphone amplifier connected to output 1 (direct)
  • From a microphone amplifier connected to output 2 (phantom loopback)


Controlling which method is used to provide phantom power is achieved with simple push switches. It is possible to concurrently power a microphone using any two of the above methods without degrading audio performance, thus providing power supply redundancy.

Ground Loop Hum Elimination

Ground loop hum problems can be quickly eliminated using the push switches to lift pin 1 of the output connectors (output 2 and 3 only).
