Sonifex DHY-04V DHY-04V Single Automatic 4G Hybrid with HD Voice, AES/EBU & Analogue I/O with Ethernet (FREE STANDING)
The DHY-04V VoLTE Hybrid is used on a cellular (mobile) phone network, and provides HD Voice quality calling over 4G, as legacy 3G and 2G mobile services in many countries are now being switched off. The DHY-04V can accept a SIM card in the rear panel slot and by connecting a suitable GSM antenna, it can receive and make high quality broadcast calls over the cellular network, converting the 4G call to the 4 wire audio signal to and from a connected mixing console. The module used in the DHY-04V can take and make calls on any 4G GSM network, and can fallback to 3G and 2G if required.
It is ideal for studios in remote locations, for OB vans and trucks on the move, and in emergency situations where a telephone landline can’t be guaranteed, the DHY-04V offers outstanding performance.
The DHY-04V has all features of the DHY-04 together with some additional front panel indicators. There are two LEDs, one for SIM enabled and one for GSM Network availability. Additionally there is a push button which allows the mobile signal level to be displayed on the meter LEDs.
HD Voice:
The signal quality can vary during the call. Normally the hybrid will be used in a fixed location (even OB trucks are normally stationary), so the position of the antenna can be refined for best signal quality. However the far end may be from a cellular phone, so may vary in quality and which can lead to dynamic bandwidth changes during a call. It is mostly true that network providers will only handle HD Voice on 4G and 3G networks though, in theory, it should also be compatible with enhanced 2G networks.
The use of HD Voice is dependent on 3 criteria:
- The method has to be supported by the network, (and this may be limited by your contract), and when different networks are involved in the call, the interoperability between the networks.
- The actual equipment used by both ends of the call must be HD Voice compatible. Both these requirements will be established on call connection, which leads to the third criteria.
- The signal quality can vary during the call. Normally the hybrid will be used in a fixed location (even OB trucks are normally stationary), so the position of the antenna can be refined for best signal quality. However the far end may be from a cellular phone, so may vary in quality and which can lead to dynamic bandwidth changes during a call.
