This paper discusses design and application of a new two-way acoustic transducer for use in multiple sound reinforcement systems inter-connected via regular telephone lines. This device provides hands-off voice inter-communication between large numbers of attendees in several remote conference rooms. The omnidirectional microphone and speakers are included in a single assembly with pickup sensitivity and output radiation adequate for most conference rooms. High gain-before-feedback is accomplished by the unique design and by acoustic phase cancellation.
