D&R HYBRID-1 User Manual - Setting Up Procedure
SETTING UP PROCEDURE
Connect a telephone appliance at the back of the Telephone Hybrid-1 (most left RJ11 connector) and connect the
(wall) phone line RJ11 connector to the “wall”. Push the "to caller" switch to connect the audio to the caller and
leave the "connect" switch in the up position for the moment.
Now dial the caller to whom you want to talk.
If this connection is made you can 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.
A practical start is to put the C adjust in its mid (12 o’clock) position and the R adjust also on its mid position.
Carefully adjusting afterwards can be realized by slowly adjusting the R adjust for optimum attenuation.
Try the R adjust for various C settings and choose the combination with the best attenuation.
This is the basic setting for most of your calls, because the line balancing to your own telephone station has to be
performed one time only, when no changes are made to the telephone system in your place.
The maximum attenuation will be around 22 to 26 dB.
The function of the "Connect" switch is to connect the hybrid to the telephone line instead of the phone itself
(which is now switched off). The led indicates that a connection has been made.
The function "to caller” is to connect calls to the mixer (pushed down) and disconnect audio from the telephone
line, without interrupting the call, for private discussions (to caller in its up position).
