The cassette deck which aimed at the still bigger
leap by the beauty of the form while realizing the performance for which 1000ZXL
is pressed.
The RAMM functionality which carries out code memory of the intelligence
on the A.B.L.E. auto calibration processor which sets up a best condition
automatically and an automatic head search of a music number, a playback
equalizer, and noise reduction is carried to all tapeses.
The A.B.L.E. auto calibration processor carried in 700ZXL is a system which
performs automatically all complicated coordinations of an azimuth, a bias
current, a sound-recording regeneration level, and a sound-recording equalizer.
Moreover, the data of the condition except the azimuth adjusted in this
way is begun,A selection of whether to use in/out of the position (70 microseconds/120microsecond)
of a playback equalizer, and the Dolbey noise reduction, or external noise
reduction,Furthermore, it is a memory possible to the tapes memory switchpoint
A, B, and C and D about the intelligence on a tapes position (EX/SX/ZX).
When this uses a tapes of the same kind next, it becomes the completion
of a coordination only by azimuth adjustment.
The double
capstan scheme is adopted. With a double capstan scheme, a tapes is held by 2
sets of pinch rollers, and a capstan. Hold down tapes rocking in a head
fraction, and a modulation noise is reduced, and also a wow and flutter property
etc. is greatly improvable.
Paying attention to a capstan and the flutter
component produced by correlation of a tapes, by changing two diameters of a
capstan, the overlap of a flutter peek was avoided and the modulation Noise
Figure is further improved in 700ZXL. Moreover, the fine oscillation produced
from a motor etc. is also effectively absorbed by study of chassis material. The
occurrence of a vibration is prevented.
In order to employ the beauty of
the design of the front panel efficiently, little switchpoint of frequency in
use and controls are covered by the ceiling panel. Playback of the tapes in
which the RAMM code was recorded can be performed without opening this cover.
Mixing circuitry built-in of a three-point mike input (L, R, L+R) and a
line input.
A Dolby NR system is built in. Since an encode and a decode
can be performed, a simultaneous monitor is possible.
External
connection noise reduction terminations (High-Com IBM PCN II etc.).
400Hz testing tone.
A subsonic speed, a MPX filter.
DC
sound-recording / play amplifier.
Rec Mute functionality.
Timer
sound-recording / play possible.
Pitch control.
High-output
headphone jack.
