The Telex BP-1002 is a single-channel wired intercom beltpack featuring a 3-pin XLR input/output configuration. These connections can be used in balanced or unbalanced situations, and the unit itself can pass power through to other beltpacks, thus daisy-chaining devices in tandem.

The BP-1002 features an auto sensor which self-determines if an Electret or Dynamic headset is attached, as well as a talk-button activated headset, a sidetone control to modulate the level of your own voice in your headset, and a light-based call feature to summon other users as needed. Additionally, the BP-1002 is Clear-Com compatible, making it suitable for use within—or orchestrating—live productions.
