Partyline: EF-701M interface wiring to JK 1rx inkeeper telco interface
Question: We are using a Clear-com Intercom System beltpack along with the Clear-com power supply to talk with our camera people. We would like to integrate this system to use with our JK Innkeeper 1rx Digital Hybrid Telco system so that the person on the telephone could talk to our camera people also. Could we buy the Clear-com CC-95 headset which would use the 3/4 connector and the 3-pin XLR connector on this headset to perform this operation? We are not ready to buy a new system but we need to use what we have to make what we have work.
Answer: In order to get the telco interface audio over to the Clear-Com party-line system a 2-wire to 4-wire convertor such as the Clear-Com EF-701M would need to be deployed. The JK interface is supplying balanced inputs (SEND) and outputs (CALLER), using the diagram below the input / output can wired to the DB-15 connector on the EF-701M which in turn converts the balanced 4-wires into unbalanced 2-wire audio for the Clear-Com party-line.
