Description
Description
DELTA 4PM is a passive 4-channel microphone splitter for professional audio applications and part of the Pamer Audio over Cat ecosystem. It enables reliable signal distribution from microphone-level sources to multiple outputs without the need for external power.
DELTA 4PM complies with the common AES72 Type 5E standard and is fully compatible with such Audio-over-Cat systems, while also integrating easily into existing infrastructures.
Each of the four channels features one THRU output for passing on phantom power, as well as 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 cable runs.
The rugged 1U 19-inch enclosure is built for standard rack mounting in both fixed installations and mobile environments. The reversible rack ears allow convenient mounting from the front or rear, providing easier access to the most frequently used connections.
Ideal for live sound, installations and recording setups where passive splitting of microphone signals, Audio-over-Cat integration and uncompromising reliability are essential. DELTA 4PM delivers low-noise, unaltered audio with maximum operational reliability. Developed in Germany. Made in Europe.
