TELEPHONE HYBRID-1 USER MANUAL V.1.
Dear Customer, Thank you for choosing the Telephone Hybrid-1. This time you are not faced with a huge manual because it is simply not necessary because of the natural recognition of all functions on the user interface. All functions are self-explanatory and you will certainly appreciate the ergonomics of this design. We are confident that you will be using the Telephone Hybrid-1 for many years to come, and wish you a lot of success. With kind regards, Duco de Rijk PRESIDENT D&R ELECTRONICA WEESP B.V.
What is a Telephone hybrid? Telephone hybrids provide the interface between professional audio equipment and the public telephone network. They provide protection for your equipment and the public telephone lines, allowing for varying line signals and line conditions. Automatically canceling out the unwanted signal they also facilitate two-way communication down a single telephone line.
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 labelled LINE (wall) and connect the telephone appliance itself to the Hybrid’s phone output on the RJ-11 connector labelled PHONE.

AUDIO CONNECTIONS TELEPHONE HYBRID TO AIRMATE From Cinch connector Connect of the Clean feed output “To Clean feed output” of the AIRMATE of the HYBRID-1 (Cleanfeed output could also be an AUX send output) ______________________________________________________________________________________________ Connect to Connect to MIC INPUT “ TO MIC INPUT” of your mixer of HYBRID-1 _____________________________________________________________________________________________
AUDIO CONNECTIONS TELEPHONE HYBRID TO ANOTHER MIXER In case you are not working with a D&R mixer the connections are pretty much the same. 1. Clean feed output or AUX output to the mixer must be connected to ’’TO CLEAN FEED OUTPUT” of the Hybrid. 2. Mic input of the mixer must be connected to “TO MIC INPUT” of the Hybrid. As the Hybrid-1 is a passive unit signal loss is to be expected so drive it with a maximum signal and connect the return telephone signal always to a mic input of your mixer.
SETTING UP PROCEDURE Push the "to caller" switch and leave the "connect" switch in the up position. Now dial the caller to whom you want to talk. If this connection is made you connect the caller to the mixing console by pushing the connect switch. Now listen by means of a PFL (CUE) switch on your mixer to the caller and adjust, while talking, the C and R ADJUST (balance) so that the outgoing signal (your voice) is best attenuated.
