The DHY-04VT is a dual version of the DHY-04V/S, providing two independent units in a single chassis. Its side-by-side configuration saves valuable space in compact or space limited rack rooms. The unit is designed for use on cellular (mobile) networks, providing HD Voice quality bidirectional audio over 4G VoLTE. As legacy 3G and 2G services are being phased out in many regions, it offers a reliable solution for high-quality voice connectivity. A rear-panel SIM slot and external GSM antenna connection allow the unit to make and receive calls over the cellular network. The hybrid converts the VoLTE signal into a 4-wire audio interface for direct connection to a mixing console, with auto-sensing combined analogue and AES/EBU inputs and outputs supporting sample rates up to 24-bit/96kHz. The XLR output is configurable for analogue or AES/EBU operation. It operates across multiple 4G, 3G and 2G bands, with automatic network fallback where available.
