and optional PZ-2L MICROPHONE
Omnicron CR-1 Conference Recorder with PZ-2L Microphone

Now you can have a quality room recording system
without the cost and complexity of old technology.


Omnicron has matched its professional voice recorder to a professional Pressure Zone Microphone®. The amazing clarity that results will completely reshape your ideas about room monitoring and recording.

Pressure zone recording is a dramatic breakthrough which eliminates the hollow sound associated with standard microphones. The distance between the microphone and the sound source has no effect on the quality of the sound reproduction.

Conventional microphones have always been hindered by interference between the sound coming directly from the source and reflected sounds. These sounds reach the microphone at slightly different times, resulting in reinforcement of some frequencies, canceling of others, producing an overall unnatural sound from distant sources.

The PZM® design of the PZ-2L microphone eliminates this interference by using the sound waves, which reinforce themselves near a flat surface, to achieve amazing sound reproduction. This is the same technology that has made the new teleconferencing systems possible.

A low noise line level amplifier is built into the microphone housing. The PZ-2L is powered by the recorder. It provides a high level output which permits long cable runs and maintains the high signal to noise ratio.

Standard four conductor telephone cable is used to connect the PZ-2L microphone to the CR-1 (standard speed) or CR-4 (¼ speed) recorders. The cable length can easily be extended up to 100' using standard RJ-11 telephone cables. You can use a T adapter, such as the Omnicron MTJ-3, to connect two PZ-2L microphones to the recorder simultaneously.

The recorder has both a fast response automatic level control circuit and manual record level control. The resulting recordings are vastly superior to recordings made with standard microphones and consumer cassette recorders.

The recorder can be switched between standard speed or ¼ speed record and playback. One quarter speed recording provides four hours of recording time on each side of a 120 minute tape. You will not understand tapes recorded at the ¼ speed if you play them in a standard speed cassette player.
