PunQtum Q110 Beltpack is a two-channel, network-based partyline intercom that operates over IP with PoE power and daisy-chain capability. Each user can talk/listen to two of up to 32 partylines, and the unit provides audio replay of missed comms (up to 30 seconds). It uses a 4-pin headset connector, 27 Ohm headphone output, and 16 kHz digital audio. The system is decentralized with no master station and can be bridged via a speaker station. It supports configurable talk-to-many channels and operates without a fixed master station, enabling portable or embedded configurations.
