Telex RTS BP325 Two Channel Intercom Beltpack Headset Station Black

Genuine Telex RTS BP325 two-channel intercom beltpack headset station in black. A professional wired intercom user station for broadcast, theatre, live events, and outside broadcast applications. Features latching talk on both channels, call signalling, and a discrete programme input feed. Accepts XLR4 or XLR5 headsets.

Powered directly from the intercom line — no separate power supply required at the beltpack. Compatible with the Telex PS-20, PS-15, PS-30, and other standard RTS 30V intercom systems.

Installation note: RTS two-channel intercom runs both channels down a standard XLR3 cable — a significant advantage for cable runs where only a single line is available. For longer runs, use standard XLR cable with a good quality shield. Avoid starquad cable for RTS intercom — the capacitance characteristics can introduce crosstalk over distance.
