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 tel-
ephone line's wall unit to the RJ-11 connector labelled LINE (wall) and connect the telephone appliance itself to the
Hybrid's phone output on the RJ-11 connector labelled PHONE. This can be done with standard available cable as-
semblies 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 labelled 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 labelled 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.
