SONY 880-2 THE WORLD'S BEST.
DIRECT DRIVE SERVO CONTROL SYSTEM.
The name may be long--Close-Loop Dual Capstan Tape Drive--but the concept is simple: one capstan is just an extension of the motor shaft itself (the other connects through a belt-drive inertia fly-wheel). Gone are the intervening gears that can often impair optimum operating reliability as well as speed accuracy. The result-almost nonexistent wow and flutter-a mere 0.02% @ 15 ips.
PHASE COMPENSATOR CIRCUIT.
Ideally, what you want on recorded tape is a "mirror image" of the original signal. No more. No less. Problem: the very nature of the recording process causes phase distortion.
Solution: during playback, Sony's exclusive Phase Compensator Circuit compensates for phase distortion. Result: sound quality that's virtually identical to the original source. (REFER TO OSCILLOSCOPE READINGS.)
SYMPHASE RECORDING.
Thanks to the durability of Sony's Ferrite and Ferrite Heads and incredible precision fabrication and alignment of the head gap, you can record any matrix 4-channel signal (like SQ or FM), play it back through a 4-channel decoder/amplifier, and retain the exact positioning of signal throughout the 360° 4-channel field. What started out in right front channel stays there. What began in left rear doesn't wander over to right rear.
There's no phase shift whatsoever.
PEAK READING VU METERS.
They're versatile. Accurate. And incredibly informative. 1. You can set for standard VU operation to determine recording level. 2. Set to display transient peaks only (up to +15 dB).
3. A third display, Peak Hold, retains transient reading, letting you accurately measure audio input and adjusts accordingly with 2-dB Stepped Record Level Attenuators.
SYNCRO-TRAK.
This means you can lay down two individually recorded tracks in perfect synchronization with each other. Record head has playback-monitor function in record mode.
This eliminates time lag that occurs when monitoring through playback head. Thus both tracks can be first generation, keeping noise levels at minimum. Flashing Standby Signal alerts you that the unrecorded channel is record-ready. And Punch-In Record puts you into record mode instantly, without stopping tape.
SONY--Ask anyone.
