0 Built~in ADRES (Automatic Dynamic Range Expan-

sion System) gives you a vast improvement in per-

formance

Overall S/N ratio:More than 80 dB (peak level, WTD)
-10 to 20 times better than
conventional systems.

Dynamic Range: 100 dB (at 1kHz) -20 to 30 times
better than conventional systems.

The A8 (Alleendust) head of the PC-XSOAD is fully
suited to i'netal tapes. The result is greater peak
margins during recording and playback in both the
mid and high frequency ranges.

O Wide Range Peak Meters

Featuring very high sensitivity (attack time of only
lOms), the peak-reading meters monitor input signals
over arnuch wider range from -40 dB right up to
+10 dB.

Die-Casting Front Panel with Integrated Mechanical
Structure

To reduce the effects of external vibrations and
ensure that tape transport mechanical performance
remains as new for much larger than normal, the
integrated transport mechanism has been incorporat-
ed directly into the precision-engineered die-casting
front panel.

Distortion: 03% (400 Hz) _1/2 that in con- Tape Transport Further Stabilized by Advanced
ventional systems. With large inputs, Mechanical 00519"
distortion is further reduced to 1/5 Tape transport in the PC that in conventional systems. stabilized by independent low-speed reel motors, a
motor~driven take-up reel tension system,and a direct-
coupled idler/reel mechanism.
Feather-touch transport mode keys for simpler,
0 Metal Tape smoother, yet faster control.

Circuitry designs ensure high quality sound reproduc-
tion.

AS (All-Sendust) head selected for superb sound
reproduction matched by equally outstanding long-
Iife low-wear characteristics.

Memory stop and memory play functions.

Automatic Recording/Playback (separate audio timer
required)
