Tetrapatch is a system for routing balanced analog audio through standard Ethernet (Cat5/Cat6) cable instead of bulky multicore snakes or DB25 looms. Each RJ45 connection carries up to 4 balanced channels. The audio stays fully analog — we just use the cable for its conductors, not its data. 

Fully analog. There's no conversion, no clocking, no latency. Tetrapatch uses Ethernet cable as a physical conductor for balanced analog audio — the signal never enters the digital domain at any point in the chain. 

AES-72 is the audio engineering standard for transmitting balanced analog audio over standard 8-conductor Ethernet cable. It defines the pinout so equipment from different manufacturers can interoperate. All Tetrapatch products are AES-72 compliant. 

Cat cable is cheap, available everywhere, easy to terminate, and far thinner and more flexible than a 25-pair snake or a DB25 loom. You can run dozens of channels through a single cable a fraction of the thickness of what you'd otherwise need. For studios doing keyboard rigs, modular synth setups, or any dense routing, the space and cost savings are significant. 

Yes. Tetrapatch adapters convert between standard balanced TRS connections and AES-72 RJ45, so anything with a TRS input or output integrates without modification. You don't need to replace your console, interface, or outboard. 

Standard Cat5e/Cat6 cable supports balanced analog audio runs of well over 100 meters without meaningful signal degradation, which is far beyond what most studios need.
