JVC KD-1770 Mark II

 For people who prefer to place their decks a top a shelf or table. JVC has designed the top-loading KD-1770, as with all JVC state-of-the-art. Audio components, the KD-1770 Mark II offers a low wow and flutter figure of only 0,05% (WRMS). This deck's motor and tape transport mechanism also are of a time-tested horizontal design proven to assure stable recording performance.

KD-1770 Mk II features:

Two sets of 5-LED Peak Indicators; One for Each Channel

Super  Automatic Noise Reduction System (ANRS)

Sen-Alloy (SA) Head and Two-Gap Erase Head

Independent Drive (ID) Mechanism

Low Wow / Flutter and Flat Response

Mic (DIN) / line Mixing

6-Pushbutton Bias / Equalizer Selection

Timer Standby Facility and Memory Stop

 Finest mechanism

The KD-1770 Mark II's exceptionally low 0,05% wow and flutter is due to the use of JVC's frequency generator (FG) servo-motor. This frequency-controlled drive unit is DC-operated for less error and is known to rotate more smoothly, provide higher torque and allow less speed deviation that AC-operated units which often are adversely affected by line voltage fluctuations. Another JVC exclusive employed in the KD-1770 MkII is an independent Drive mechanism which allows the capstan to rotate independently of the deck's reels. The result is accurate tape speed and elimination of reel-caused "tape drag".

Versatile Recording Aids

The KD-1770 Mark II has two JVC 5-LED peak indicators (10 LEDs in total) to allow monitoring of all signals - left and right channels - at a glance. Also included are two pairs of input level controls - one for Mic/DIN and one for Line. Plus two pairs of circuits - one pair for the left channel and one for the right channel. Thus you can mix mic signals with line inputs from a turntable, tuner or second tape deck. Or you can dub voice or guitar accompaniment into an FM program. Separate inputs for Mic/DIN and Line also mean low distortion and high signal-to-noise ratio. Needless to say, the above capabilities make the KD-1770 Mark II an extremely useful machine.

Convenience features

Recording and playback are a pleasure if you use a KD-1170 MkII deck, but its technical versatility doesn't mean it's difficult to operate. Indeed, it boasts many easy-to-operate features, including a memory Stop mechanism, an Air-Damped Cassette Lid; a photo-electric Full Automatic Stop Mechanism to prevent tape stretching and motor wear; an illuminated cassette compartment which allows easy cheking of tapes; a removable cassette lid to make head-cleaning simpler; mirrored VU meters for precise record level readings.
