The Soundweb London Telephone Hybrid Cards are designed to populate any of the four card slots on Soundweb London BLU-800, BLU-805, BLU-806, BLU-320, BLU-325, BLU-326, BLU-160 and BLU-120 devices. These cards enable Soundweb London devices to interface with a standard POTS (aka PSTN or Analog PBX) telephone network.


The BSS Audio Soundweb London Telephone Hybrid Card is a specialized expansion module designed to integrate standard telephone lines into Soundweb London digital signal processing systems. Compatible with a wide range of Soundweb London devices—including the BLU-800, BLU-805, BLU-806, BLU-320, BLU-325, BLU-326, BLU-160, and BLU-120—this card allows you to interface directly with a POTS (Plain Old Telephone Service) network, also known as PSTN or analog PBX.
Perfect for teleconferencing, paging systems, remote audio feeds, and broadcast applications, the Telephone Hybrid Card offers a clean and efficient way to manage telephone audio within a digital AV environment.
In addition to telephone connectivity, the card features two analog audio inputs—each capable of accepting microphone or line-level signals. These inputs provide software-controlled gain in 6dB steps from 0dB to 48dB, along with individually switchable phantom power, offering full flexibility for integrating professional microphones or external audio sources.
By combining telephony and analog input capabilities, the Soundweb London Telephone Hybrid Card is ideal for corporate AV, education, broadcast studios, and government facilities needing reliable telephone audio integration.
For AV professionals seeking to bridge telephone systems with high-performance digital DSP networks, this hybrid card delivers a compact, scalable, and robust solution.
