Team Electronics introduces the Spectro Peak Indicator
JVC's25-LED idea lights the way to perfect cassette recordings
With each technological advancement JVC gets a little closer to the original sound or, as they say, "The Musical Truth." When the perfectly silhouet, statally automatic, distortion-free cassette deck apprehends JVC technology will have made it possible. The latest of its advancements is here now. Spectra Peak Level indicator, or "SPI" for short. It's an ingenious new way to monitor hi-frequency ranges (spectra) so that you can record with the widest possible dynamic range, with virtually no trace of distortion. "SPI" lets you get the very most of today's premium tapes, and also to make the most of Super JARS (automatic noise reduction) on JVC decks. It's available on the KD-85 (right) and the KD-65 (left) in Team Electronics' SoundRooms Here's how it works.
100Hz 300Hz 1kHz 3kHz 10kHz
Spectre Peak Indicator indicates the levels (+, +6, -0, 5 and -10 of all five frequency ranges (100, 300, 1k, 3k, and 1kHz) instant to instant. The charts at right represent the relationship between the SPI indication and the level-by-level frequency response of a cassette tape. Since the SPI has two twenty-five peak-reading LED's — each responding within one millisecond — you have much more control than if you depended on VU alone. As you record you can visually monitor to high frequency peaks that are likely to cause distortion and make the appropriate level adjustments to prevent distortion before it can happen. You increase the recording level (*Music A*) or decrease it (*Music B*) according to the tape linearity. With the assistance of the SPI, best recording can be made by seeing that some LEDs do not light at all even during loud passages, others light constantly throughout, and the rest flicker freely during loudest passage. The chart at right represents the procedure to follow to get the least distorted, widest dynamic range recording both from mid-rich and treble-rich music sources. When you playback the cassette, you know at a glance at your Spectre Peak indicator whether it's bass-rich, mid-rich or otherwise
Optimum Recording Level Setting for
Maximum Linearity
ANRS GP SP RE DB THE INNOVATIONAL KD-85: A CASSETTE DECK $49995 THAT MEASURES UP TO OPEN REEL QUALITY
If you thought you had to sacrifice fidelity in tape recording to enjoy the convenience of a cassette deck, then consider these vital statistics. JVC's newest stereo cassette deck, the KD-85, has a 30 to 16,000 Hz $ \pm $ 3dB frequency response with chrome tape, a better than 6dB s/N ratio (ANRS off) and an extremely low 0.05% wow/futter (VRMS). Figures roughly comparable to those of open-reel recorders. And the advantages of the KD-85 can hardly be compared. If you have ever tried and failed to capture (without distortion) the sudden high peaks of a jazz trumpet, or the clash of a cymbal, you'll be thrilled with what you can do with the Spectro Peak Indicator and Super ANRS features on this deck. You can make a perfect recording every time, with no trace of distortion across the entire frequency range. The KD-85 has every one of the JVC innovations described below, except MPi, which is superseded by SPI. It doesn't stop there, either. There's a two motor ID mechanism that results in the unusually low wow/futter figure. Full logic controls that permit switching from one mode to another without stopping. Memory stop. Delayed time recording. And a lot more we'll show you when you come in.
JVC CASIETTE TAPE DECKS RECORD "CLOSER TO THE MUSICAL TRUTH" THANKS TO THESE EXCLUSIVE INNOVATIONS AND IMPROVEMENTS
Like the Spectro Peak Indicator, this
popular JVC exclusive Multi-Light LED popular indicator withfive LED's lets you easily determine optimum recording level by indicating peak levels at -10, -5.0, +3, +6 dB. This peaking capability helps you expand the dynamic range by avoiding tape distortion caused by peaks, unreflected by VU's, are applied to the recording amp.
A tape's high frequency response differs
from deck tide担当 because every tape requires a different bias and equalization for bet recording results. On some decks response may drop sharply, while another it tends to rise. This variability happens when the tape is not aligned — it happens which has been solved by JC's Recording Equalizer Switch. It let you fine-adjust your deck so you'll have a flat frequency response from whatever tape you use.
SuperANRS
The Super ANRS (Automatic Noise Reduction System) improves the signal-to-noise ratio of recording/playback as much as 5dB at 1kHz and 10 dB at 5 kHz or more, greatly reducing the tape што that so often mars soft passages. It also expands the high frequency linearity by 6dB (OVU) and 12dB (+SVU), both at a high 10 kHz, with less than 3% total harmonic distortion. Even shirld pincillars are recorded without a trace of distortion.
Oil instead of a usual snap-in/inout spring loaded cassette lid, JVC has developed a sophisticated one with a toasted rack, oil-damped gear/disc and spring-loaded brake shoe. As the lid's clutch is released to open the door, the rock's movement is controlled by the oil-damped gear/disc, allowing the lid to open smoothly and silently.
JVC's exclusive Sen-Allay head employs a very special metal alloy which JVC was first to apply to cassette decks for home use. It improves signal-to-noise ratio, since it works as a shield against magnetism. Plus - it induces less eddy current, has better high frequency response and more mechanical precision in gap design as compared to other types of Sendust formulations.
Two-Gap Erase Head a high performance recording
___ high performance recording head such as JVC's "SA" needs an erase head equally as advanced, and this one bills the bill. It features a high erasure factor and a low noise for clean recordting. Even tape with high magnetic properties can be erased effectively and distortion reduced.
Spectra Peak Indicator, as described above, is JVC's latest grant step towards ultimate fidelity in cassette tape recording. It gives you for greater control than VU meters alone, with a visual display of the high frequency peaks likely to cause distortion, in time to make adjustments to prevent it.
Dual Ball Cassette Hold System — another JVC exclusive for better musical performance. The two precision finished stainless steel balls in the cassette holder secure your tape with constant pressure. Cassette misalignment — a cause of faulty response — is impossible and stable tape transport is the result.
JVC's Independent Drive or ID Mechanism drives
the mechanism drives the capstan independently from the reels. Therefore, a reel cannot drag the capstan,挡震 the precision of the load, or loss of accuracy or otherwise impede accurate tape speed. The result is low wove and flutter and outstandingly accurate sound reproduction.
Timer Standby Facility with this plus a timer
with this product
switch (available at event sites) you can record and play a tape unbounded. You can even make recordings off the air while you're awake, or woke up to music on tapes every morning . . . a beautiful way to greet the day.
