RTS BP-325 2-Channel Portable Beltpack Station (Black)

Styled in black, the Telex/RTS RTS BP-325 is a 2-channel portable beltpack station designed to work in conjunction with RTS Two-Wire intercom systems and the appropriate, dynamic headset mic. It facilitates conversations across the air-waves in one of two fashions: you can either hold down the Talk button—which instantiates momentary mode, allowing you to remain inaudible when you're not pressing the button—or, conversely, tap the Talk button a few times, which will occasion the mechanism to latch into an ever-on position. Be advised, if you instantiate latching mode, everything you say will be heard until such time as you turn it off. 

This unit also sports the ability to send out a call signal, should you need page someone on one of the two provided channels. Likewise, you might also find yourself paged; in this case, the red call LED will flash, presenting you with the opportunity to speak with the person courting your attention.

The RTS BP-325 also features a sidetone adjustment control for changing the level of your own voice in your discrete pair of headphones whilst talking. The unit supports mono and stereo headsets, and there's also a separate connector for monaural carbon-mic headsets. Furthermore, the RTS BP-325 sports the ability to generate an inaudible signal which can effectively "kill" the ongoing signals of unattended intercom stations.
