PROMS2
PROMS2 @ Passive Microphone Splitter
ProMS2™ Passive Microphone Splitter
- High performance Eclipse transformer for optimal signal transfer
- Equipped with direct, isolated and auxiliary outputs for 3-way split
- May be rack-mounted in the J-Rak for multi-channel use
- Rugged 14-gauge steel construction for added durability and shielding
The Radial ProMS2 is a high performance mic splitter that accepts a balanced microphone signal and sends it to three outputs simultaneously. As a passive device, there is no need for power – you merely plug in and the ProMS2 automatically springs to life to deliver pristine audio without artefact or color.
The magic inside the ProMS2 is a premium Eclipse ET-MS10 transformer. This features a nickel laminated core that delivers a wide frequency response and exceptional signal handling with virtually zero distortion at all frequencies. And with better than 115dB of common mode noise rejection, you can rest assured that hum and buzz caused by ground loops and stray DC currents will be kept at a minimum. To shield against stray magnetic fields, the transformer is doubly protected with an integral MuMETAL® can plus a rugged external steel enclosure. This is augmented with RF filtering and a 100% discrete signal path to ensure optimal signal flow.
As with all Radial products, construction begins with a rugged 14-gauge steel for maximum durability. A unique book-end design creates a recessed zone around the switches and connectors to protect against the harsh environment of concert touring. An internal I-beam frame makes it virtually impossible to torque the PC board which could otherwise compromise the sensitive solder joints. The innovative design has the unique advantage of allowing up to 8 units to be rack-mounted using the Radial J-Rak. Typical applications include splitting a signal in the studio to feed more than one preamp, feeding a stage mic to more than one mixing console, or even splitting the signal from a live stage to supply a broadcast feed.
The Radial ProMS2 is a great sounding problem solver that lets you split microphone and DI signals with ease and confidence.

1. -30dB PAD: Allows balanced +4dB line-level sources to connect to the
ProMS2 input.
2. Mic input: Used to connect a low impedance, balanced, microphone or
direct box.
3. Direct-1 thru: A parallel direct output used to bridge the mic or DI to
the primary mixing console.
4. Bookend design: 14 gauge steel outer shell creates protective zone
around connectors and switches.
5. Full-bottom no-slip pad: This provides electrical isolation and plenty of ‘stay-put’ friction to keep the ProMS2 in one place.
6. Direct-2 output: Equipped with ground lift. Used to bridge the signal to an additional audio device.
7. Lift (Direct-2): Disconnects pin-1 (ground) on the direct-2 XLR output to help reduce hum and buzz caused by ground loops.
8. Isolated output: Transformerisolated to eliminate ground loop hum and buzz. Used to bridge the balanced mic signal to a second audio system.
9. Lift (Isolated output): Disconnects pin-1 (ground) on the isolated XLR output to help further reduce hum and buzz caused by ground loops.
10. Steel I-beam: Enclosure eliminates stress that could torque the PC board.
11. Military-grade PCB: Doublesided PCB with plated through-holes is bolted to welded steel standoffs.
12. Eclipse: High performance mic bridging transformer offers outstanding
audio performance. Features mu-metal shield for protection against stray electromagnetic fi elds
