Description
The 1/2 track record + 4 Track PB Teac A-6700DX was designed for studio use and was only available in the Japanese Market. With a separate transport and preamplifier, the two parts of the machine are connected with cables that are attached and stored in a compartment at the back of the transport. An RCA tape head output is provided that connects the two and is also very useful if you prefer to Up your game and use modern day tape head preamplifiers. NAB and IEC compatible. Full logic controls for switching through the various functions without engaging stop.
Speed stability It is controlled by a tension servo and impedance roller. The tension servo maintains proper back tension as the amount of tape changes in the supply reel as the impedance roller absorbs uneven running due to a flywheel effect. Fairly versatile on recording with a peak level indicator as well as L + R Rec Fine Input adjustment with master control.
In appearance and function, it compares to the Tascam 35-2 and looks similar to the Teac A-6600 an auto reverse machine that was available in North America The A-6700 appears to be a very rare machine with very few to be found in Japan or elsewhere of course.
