USER MANUAL

The D&R Telephone Hybrid-1 is designed to create an easy connection between the public

telephone line and your studio equipment.

The Hybrid has to be inserted between your telephone and the telephone line. Connect the two

wires of the telephone line's wall unit to the RJ-11 connector labeled LINE (wall) and connect the

telephone appliance itself to the Hybrid's phone output on the RJ-11 connector labeled PHONE.

This can be done with standard available cable assemblies from your local phone shop.

Now the Hybrid is interfaced (fully balanced) between your telephone appliance and its

connection to the outside world. The hybrid can now split the send and return signals.

Now connect the hybrid's balanced audio input labeled TO CLEANFEED OUTPUT to a (preferable)

balanced output of around +4dBu. This output has to be the mix of all signals except the signal

coming from the hybrid itself to avoid feedback.

An Aux. output on your mixer will do as well as long as you keep the Aux. send of the channel

you return the phone signal on closed (all other Aux. sends need to be open), or in broadcast

mixers a clean-feed is the best.

The Hybrid-1 stereo jack connector labeled TO MIC INPUT has to be connected to a Mic level

input of your mixing console.

NOTE: The output of the Hybrid has to be connected to a Mic input of the mixing console,

because the outgoing level is very low because of the passive circuitry inside the Hybrid.
