DELTA 4PL - 4-Channel Passive Line Splitter with Audio-over-Cat

DELTA 4PL is a passive 4-channel line splitter for professional audio applications and part of the Palmer Audio over Cat ecosystem. It reliably distributes line-level signals to multiple outputs without the need for external power.

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

Each of the four channels provides one THRU output and two galvanically isolated, transformer-balanced XLR outputs. Symmetrical signal routing with impedance matching ensures clean transmission and eliminates ground loop noise. All 4 channels can also be transmitted via a single Cat cable, which is especially useful in fixed installations with limited or discreet cabling.

The rugged 1U 19-inch housing is designed for standard rack mounting in both permanent 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 installations, studios, and touring setups where passive signal splitting, Audio-over-Cat compatibility, and maximum reliability are essential. DELTA 4PL delivers pure, unaltered audio and robust performance. Engineered in Germany. Made in Europe.
