Additional Details
Description
An impressive and versatile four channel recorder with Multi-sync recording, postion/repeat play memory, solenoid controls and impressive specifications. From an equipment test report by Hirsch-Houck Laboratories (1976) “…. We found the tape-loading process to be exceptionally simple, even for someone with more than the normal quota of thumbs. All solenoid-controlled recorders emit an audible “clunk” when their control buttons are operated, and this one is no exception. In any event, none of the acoustic output of the solenoids affects the taped program. All in all, the performance, versatility and striking physical design of the Dokorder 1140 add up to make it an outstanding value despite its not inconsiderable price…..”
