The BP-6000-A4M is a portable user station compatible with Audiocom and Clear-Com party line systems. The BP-6000 is a 2-channel beltpack equipped with a mode-sensing system configuration, meaning the beltpack determines what type of system it is installed into and configures itself according to the system. The BP-6000 has a 4-pin male XLR connector with auto-sensing headset inputs. Dynamic and electret headset microphones are supported. The loop and line connection both use 6-pin Switchcraft connectors. Multiple programming options are available. To simplify programming, voice prompts guide the user through the menus.
