The Soundweb London Telephone Hybrid Cards are designed to populate any of the four card slots on Soundweb London BLU-800, BLU-320, 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 Soundweb London Telephone Hybrid Cards also have two analog inputs which allow each Telephone Hybrid Card to receive two microphone or line level signals. These analog inputs offer Phantom Power, configurable per channel and software controlled analog gain in 6 dB steps from 0 dB to 48 dB.

The Telephone Hybrid Cards each have two Combicon connectors which are used as follows:

Connector 1
Balanced / Unbalanced Audio, Channel 1 - Mic/Line
Balanced / Unbalanced Audio, Channel 2 - Mic/Line

Balanced Unbalanced
Connector 2
Tip / Ring, Telephone Line Connection
Tip / Ring, Parallel Set Connection

Connection to telephone system involves high voltages. This device must be installed by qualified personnel.
Connections to the telephone network must be made with #26 AWG solid copper wire to meet UL 60950.
