D&R Telephone Hybrid-1, passive one line POTS

Description

  the passive one line connection,
to the best stories ever

The D&R Telephone Hybrid-1 is an interface between a standard telephone line and a mixing console.

Its purpose is to enable to record or broadcast a conversation between a caller and a presenter

in an easy way.
Superb audio separation between in and outgoing signals are achieved by carefully designed

internal circuitry.

It is a problem solver for changing two wire communication into a four wire system with separate in and outputs.

With its Private “TO CALLER” button you can easily temporarily disconnect the caller from the mixer (broadcast) for private conversations.
