About StudioHub+
StudioHub+ (now Angry Audio) is a broadcast audio wiring standard using shielded Cat5e/Cat6 STP cable and RJ-45 connectors to carry balanced stereo audio throughout a facility. Wiring follows the T568B color standard, compatible with standard Ethernet patch panels and keystone jacks. Pin 4 and the cable shield serve as the common audio ground.
Pins 7 & 8 carry optional ±15V DC when used with StudioHub+ powered Cubes or Hubs. Do NOT connect to Ethernet switches.

Wiring Notes
| Topic | Detail |
|---|---|
| Cable Type | Shielded Cat5e or Cat6 STP required — unshielded UTP not recommended for audio |
| Max Length | Up to ~300 ft (90m) for analog; shorter recommended for AES/EBU digital |
| AES/EBU Digital | Uses Pins 1 & 2 (same pair as Left analog). 110Ω impedance. Green Band adapters. |
| Ground (Pin 4) | Pin 4 and cable shield are bonded as audio GND inside all standard adapters |
| DC Power | Pins 7 (+15V) and 8 (−15V) only active on StudioHub+ powered Cubes/Hubs |
| Compatibility | Works with Axia (Telos Alliance), Wheatstone, and all StudioHub+ equipped gear |
| Patch Panels | Standard 110-block or keystone patch panels work; punch down to T568B |
