Description
The Dokorder 714 was a 2/4-channel
stereo tape deck offering full 4-channel recording and playback, as well
as conventional stereo quarter-track operation. It was an ideal recorder
for the semi-professional and advanced home user and was the least expensive
4-channel recorder on the market.
The record sync (Multi-Sync) function feature allowed the monitoring
of pre-recorded tracks whilst adding new tracks with exact synchronization
and was an ideal deck for making multi-track demo recordings if the Teac
A3400 was unaffordable.
Other features included electronic echo, sound-on-sound, sound-with-sound,
four large VU meters, tape/source monitoring, solenoid controls, three
motors, three heads, tape bias selector and mic/line mixing
Additional images of this recorder are supplied on the Get Reel Contemporary
Classics CD-ROM.
