  • Notes

  • The Berlant Broadcast Recorder Model BR-1 consists of two sections: The broadcast recorder drive mechanism, BD-1, and the broadcast recorder amplifier, BA-1. The amplifier contains all the elements necessary to supply the erase and record heads of the mechanism with power, and to amplify the signal from the playback head to meet the requirements of a 600-ohm zero level distribution line. The drive mechanism accommodates all size reels up to and including the standard NARTB 10 1/2" professional reel. Instantaneous selection between 15 inches per second and 7.5 inches per second tape speed is provided, with aoutomatic correction of qualization.
