BSS BLU-HIF - Telephone Headset Interface

The BSS Audio BLU-HIF telephone headset interface makes it easy to connect the headset jack of a VoIP/digital telephone to an AEC input and analog output of a Soundweb London device. The BLU-HIF thus allows the VoIP/digital telephone to be used as the dial-up and hybrid interface for a conferencing system. This simple interface eliminates the programming requirements associated with third-party control systems, while providing a familiar, low-cost dial-up interface for the end user. The BLU-HIF features an RJ-22 connector for connection to the headset jack of a VoIP/digital telephone, a balanced input (Tx) for sending near-end audio, and a balanced output (Rx) for receiving far-end audio. Although the BLU-HIF provides substantial isolation of the Rx and Tx signals, near-end audio will still be heard on the Rx channel due to the presence of sidetone. As such, BSS Audio recommends always feeding the Rx channel into an AEC input, rather than a standard analog input. The AEC algorithm will eliminate sidetone. The Tx channel connects to a standard analog output. The wiring configuration inside the headset jack of a VoIP/digital phone often differs, depending on the manufacturer. The BLU-HIF comes with two cables whose RJ-22 4P4C connectors are compatible with the two most common wiring configurations found on the headset jack of VoIP/digital phones. The additional 2.5 mm jack makes it easy to connect two-way communication devices, such as cell phones, to the Soundweb London device. This gives the end user the advantage of having an alternate communication path to the outside world, which is particularly useful as a backup to the main telephone system.
