JVC DD-7 cassette-deck

Direct-Drive Cassette Deck DD-7 features:

Quartz-lock, direct-drive mechanism with Pulse Servo motor

Three-head configuration - Monitor capability with the X-cut SA combination Rec/Play head and extended highs

Two-colour digital fluorescent level meters - Choose peak-hold or VU modes

All-DC amp configuration = Low noise and sonic clarity

Full-logic control  - Foolproof operation and touch control

Super ANRS and Dolby-B compatible ANRS

 

Direct-drive system built around the JVC Quartz-lock Pulse Servo motor

Simple is better when it comes to tape transport design. The proof is in the figures - wow and flutter is only 0,06% (DIN 45 500). Our Pulse Servo motor takes a lot of the credit, being immune to cogging, voltage fluctuations, and changes in temperature and humidity. Speed is quartz-locked to assure unblemished accuracy over the years.

 

Three-head design with JVC exclusive SA heads

The material used in our SA (Sen-Alloy) heads is capable of providing optimum results from any tape, particularly metal tape. Furthermore, we've given the Play head a narrow 1-micron gap for efficiency and a contour-free surface for extended bass, while the Rec head has a wider 4-micron gap to pick up high frequencies without loss. Our X-cut Rec and Play heads - separate but combined in a single casing - are complemented by our two-gap erase head, also of SA.

 

Monitor peak or VU level depending on your needs.

Different recording situations require different recording levels. That's why we/ve equipped the DD-7 with meters having selectable modes - peak-hold reading or VU.

 

Recording EQ: For a flat high-frequency response

The Rec EQ control allows the deck to tune itself to any tape for flat response to 15 kHz and beyond and the separate playback head lets you confirm this as you are actually making recordings.

 

Lockable timer standby mechanism ends erroneous erasure

The timer standby is locked during power outage; it can't be nudged to Rec to prevent accidental erasure

 

Memory auto rewind: Both atop and play modes.

This is a convenience feature that you shouldn't be without. It lets you continuously repeat the tape from beginning end (or from 999-indexed portion to end), or rewind the tape at the end of play.
