The HBP-2X is a rugged and ergonomically designed 2-channel digital partyline beltpack. A beltpack can have access to two of any four system channels over a single shielded twisted-pair cable.
HBP-2X Beltpack Highlights
Channel Density. Similar to a source assignment panel, a single cable gives every connected beltpack the capacity to access all four system channels.
Selectable Channels. The full-duplex, 2-channel beltpack can select up to two of the available four system channels and access program audio, each with individual level control.
Save Resources. Networked audio is distributed over a single, shielded twisted pair, reducing the number of cables to yield time and cost savings.
Passively Interconnection. Beltpacks can be set up in daisy-chain or star configurations with no need for active split boxes.
Clear-Com Sound: Legendary contoured audio frequency response provides maximum intelligibility and exceptional sound quality.
Efficient Administration. System configuration and firmware upgrades are centrally managed from the main station.
Intuitive Operations. Present logical channel labels on the high-contrast, 10-character OLED display.
Effortless Navigation. Optimally positioned buttons and volume knobs are easy to locate, identify and control on the beltpack.
Highly Durable. Fabricated from lightweight cast aluminum, the beltpack is able to endure the rigors of intensive applications.
