A Transistorized Professional Tape Recorder

Document Thumbnail

This paper discusses the problems of designing a recorder capable of recording at any of six tape speeds from 3-3/4 ips to 30 ips, with domestic or international versions of equalization, and with the widely varying record characteristics of the types of tapes in use today. Each equalizer is capable of being contained in a small plug-in housing. Two such housings for two different tape speeds with a relay to select the desired equalization are provided. The units treated will be: (1) in the reproduce section-the reproduce preamplifier, reproduce calibration amplifier and line amplifier; and (2) in the record section-the record calibration amplifier, record equalization circuit, record head amplifier, and the erase and bias oscillator. The design of the regulated power supply will be described, as well as the methods used to prevent audible disturbances being recorded on the tape when the record section is turned on or off.
