The Revolutionary Sony Elcaset System
Wow & flutter: AM. Signal/noise ratio: 62 dB. Freq. Response: 25 hz to 22khz +-3db.
Introducing the incredible Elcaset system. Developed by Sony to bring you unsurpassed cassette sound.
1. The Elcaset tape is as wide as reel-to-reel tape: ¼”.
2. Tape moves twice as fast: 3 3/4 ips. Result: the widest dynamic range, the widest frequency response, the X Automatic tape formulation cleanest sound ever offered in a cassette format. Unlike the standard on the cassette case "tell" the Elcaset cassette, the Sony Elcaset sound is not compressed, constrained. It's expansive and full. It "breathes”. It's true high fidelity.
3. The tape is lifted out from the cassette and guided across the heads by a stabilizing pin in the deck itself--just as in reel-to-reel.
Result: lowest wow and flutter, superior tape/head alignment, even better frequency response. (see diagram)
4. All-new tape formulation with thicker oxide coating and thicker polyester for highest quality sound.
5. Automatic tape formulation adjustment. Small holes encoded on the cassette case "tell" the Elcaset deck what type of tope is being used (SLH, FeCr). The Elcaset then automatically adjusts both bias and EQ for optimum performance.
An engineering triumph, the Sony EL-7 Stereo Elcaset Deck was designed exclusively for the new Elcaset tape.
1. A Closed-loop dual capstan tape drive. One of the most advanced tape drive systems now available, it assures constant tape-to-head contact pressure, low wow and flutter and virtually nonexistent modulation noise.
2. The 3-motor system starts with a DC servo motor for utmost reliability. A sophisticated feedback circuit corrects for line voltage fluctuations, and other speed-altering factors. This is the finest tape recorder motor system money can buy. Proof? Wow and flutter of only .04%.
3. Sony's 3-head system offers the ft most precise tape/head alignment possible. All three heads are made of ferrite and ferrite-a super strong formulation that lasts up to 200 times longer than standard permalloy. Head surfaces are mirror-smooth for friction-free tape travel and optimum tape/head contact. Incredibly close tolerances in the head gap assure widest frequency response.
4. Direct coupling of playback head with the FET first-stage reproduction amplifier significantly reduces distortion, improves signal/noise ratio and frequency response linearity.
