3. TECHNICAL DATA
(subject to change without notice)
@ Adjustable to mains voltages of 110 (100 - 120), 127
(115 - 130), 220 (200 - 230) and 240 (230 - 250) Volts
with voltage adapter (52).
@ Suited for 50 and 60 Hz alternating voltage. Only the
timer (39) should be set to 50 or 60 Hz.
Accepts reels with a diameter up to 26.5 cm (10 1/2").
Tape width 6.25 mm (1/4").
Four-track system.
Track configuration in accordance with IEC standards.
Three tape speeds: 19, 9.5 and 4.75 cm/sec.
Max. playing time (stereo) with 1080 m tape (26.5 cm
reel with LP tape) at 19 cm/sec: 2x1 1/2 hours (reverse).
© Fast winding: 1080 m tape (26.5 cm reel with LP tape)
within 250 secs.; 540 m tape (18 cm reel with LP tape)
within 150 secs.
®@ Provided with two head-systems, each consisting of one
erase head, one recording head and one playback head;
(six heads in total).
® Provided with two capstans and two pinch rollers, one set
for each tape-transport direction.
@ Equipped with one Hall-effect motor (collectorless D.C.-
motor) for driving the capstans and two D.C. motors for
driving the turntables.

1) For suppression of the annoying whistle-tone during stereo
radio transmissions, the input circuits of inputs "TUN" (tuner;
51) and "AUX" (auxiliary; 48) include a filter which reduces
the frequency range for both inputs to 16,000 Hz.
