The Dual C830 is a
machine that not only handles ferric, chrome, ferrichrome andd metal tapes, it
has two values of bias for both ferric and chrome tapes, thereby providing an
optimum bias match for all commonly used formulations. Though it has a three-head
system with simultaneous record-play, there is no simultaneous Dolby decorder;
the simultaneous monitor exactly reproduces the recorded sound - the Dolby
decoder is active only in the play mode. A record limiter cuts in at 0 dB
record level with a fasy attack and release, thereby protecting against
unsuspected excessive signal pecks. The record level indicator is not frequency
compensated and indicates the true peak value after record pre-emphasis is
applied. The 12-step LED record level indicator is very easy to read.
The C830 has a
direct-access front loading mechanism, automatic stop at the end of play and a
memory reset counter. It also features adjustable headphone volume,
microphone/line input mixing and fade-erase during playback.
