For people who prefer to place their decks on an open shelf or table, the CD-1770 has the time-tested top-load design. Its reliable tape transport mechanism offers a low wow and flutter of only 0,12% (DIN 45 500) or 0,04% (WRMS). JVC's own ANRS/Super ANRS noise reduction systems. SA (Sen-Alloy) record/playback head, 5-LED Multi-Peak indicator and other numerous technical features assure exceptional versatility and dependable performance.
Finest Tape Transport.
The exceptionally low 0,12% (DIN 45 500) wow and flutter in this fine deck is mainly credited to the use of a frequency controlled DC servomotor. It provides more stable and higher torque and less speed deviation than AC-operated motors. A dual-belt independent Drive Mechanism, another JVC-exclusive is also used to drive the capstan and the tape reels separately, thus preventing the vibration of the tape reels from affecting the capstan revolution. This further assures exceptional speed accuracy at all times.
Versatile Recording Aids
The CD-1770 offers JVC's 5-LED Multi-Peak Indicator in Addition to a pair of large level meters. This Indicator responds even to pulse-like peak signals of very short durations. Using the indicator and the level meters together will enable you to adjust the recording levels to the maximum and avoid distortion. There also are two pairs of recording level controls for MIC (DIN) and Line, to let you mix microphone signals with line inputs from any programme source of your choice.
Convenience Features
Memory Tape Counter for memory stop. Air-damped cassette compartment lid. Full automatic stop, illuminated cassette compartment for easier tape inspection Six push-button Bias and Equalizer selectors to obtain maximum performance from any kind of tape. Timer Standby facility.
