Mitsubishi
DT-30
(1979 - 1980)
Exceedingly
rare bigga tape recorder with interesting looks of the sci-fi kind,
added later in time to the 1977 Mitsubishi / Diatone lineup which
comprised the DA-P20 dual-mono preamp,
DA-C20 preceiver, DA-A10DC
& DA-A15DC dual-mono powerhouses
and DA-F10 & DA-F20
FM tuner.
A
lot of functions, switches, knobs and buttons, even if the measured
specs aren't really sci-fi. Three heads (ferrite for record and
erase, sendust for replay), three DC motors with closed-loop dual
capstan for the drive motor, a mix function with independent levels
fo the MIC and LINE inputs, precise VU meters with three-seconds
peak hold, soft-touch buttons, two test signals for calibration
(440Hz and 8kHz) and bias fine-tuning for both channels.
Added
for the upcoming 1980s decade : ASPS
and synchro rec/play
with Mitsubishi record players !
Automatic Spacing Pause System allows to record three-second blank
spaces - useful to later on skip from one recording to another...
but that function wasn't offered on the DT-30 :)
Turntable synchro allows to launch recording of a record only by
pushing the record transport pad : the DP-EC20
turntable automatically starts playing !
There
probably was a japanese Diatone
equivalent of the DT-30 but I haven't got anyhting on it yet.
