DELTA 4PM 4-Channel Passive Microphone Splitter with Audio-over-Cat

DELTA 4PM is a passive 4-channel microphone splitter for professional audio applications and part of the Pamer Audio over Cat ecosystem. It allows reliable signal distribution from mic-level sources to multiple outputs without the need for external power.

Compliant with the common AES72 Type 5E standard, DELTA 4PM is fully compatible with such Audio-over-Cat systems and integrates easily into existing infrastructures.

Each of the four channels features one THRU output for phantom power passthrough, along with two galvanically isolated, transformer-balanced XLR outputs. The design includes impedance matching and resistor-decoupled isolation to ensure clean signal routing, eliminate ground loop noise, and preserve phantom power functionality. All 4 channels can also be routed via a single Cat cable, which is especially useful in fixed installations with limited or discreet cabling.

The rugged 1U 19-inch housing is built for standard rack mounting in both fixed installations and mobile environments. The reversible rack mounts allow convenient mounting from the front or rear for easier access to the most frequently used connections.

Ideal for live sound, installations, and recording setups where passive mic signal splitting, Audio-over-Cat integration, and uncompromising reliability are essential. DELTA 4PM delivers low-noise, unaltered audio with maximum operational safety. Engineered in Germany. Made in Europe.
