YAMAHA NS-1000/1000M (1974) - Pure Beryllium Masterpiece

Loudspeaker

The NS-1000M was the world’s first speaker system to have diaphragms made of beryllium of 99.99% purity — previously considered unobtainable — in its midrange and tweeter. The speaker offered the accuracy and clarity of audio reproduction made possible only by beryllium diaphragms that have an excellent transient response, and earned critical acclaim both at home and overseas immediately after it hit the market in 1974. It was adopted as a studio monitor speaker by the Swedish national broadcasting corporation in 1976, and by the Finland national broadcaster with 200 units ordered in 1978. Even after its successors, the NS-1000X and NS-2000, were introduced, the NS-1000M remained popular and had sold more than 200,000 units over a period of 23 years — before the production of beryllium diaphragms ended and the marketing of the legendary speaker was discontinued in 1997.

Yamaha developed the world's first hard-dome drivers with beryllium diaphragms — the JA-0801 8.8 cm midrange and the JA-0513 3.3 cm tweeter. Beryllium, considered as the ideal diaphragm material for its hardness, lightweight (low density), and stiffness, was extremely difficult to be molded into a diaphragm. Yamaha overcame the challenge of processing beryllium with its proprietary electron-beam vacuum vapor deposition method. The overwhelming sense of spaciousness and clarity made possible by the beryllium diaphragms that took advantage of the metal's sound velocity (higher than that of any other practical metal) shattered the perception people had of speakers — so much so that the NS-1000M, the first speaker system to feature beryllium diaphragms, earned wide acclaim from audiophiles and critics worldwide. Later, the NSX-10000 released in 1986 came equipped with GC beryllium diaphragms made of giant beryllium crystals, and the GF-1 introduced in 1991 featured forged beryllium diaphragms. Until the production of all beryllium diaphragms was discontinued in 1997, a hard-dome driver for Yamaha was synonymous with a beryllium-dome driver.

Positioned as a high-end unit for home use and priced at 145,000 yen at the time of its release, the NS-1000 featured an ebony luxury urethane paint finish exterior, while the NS-1000M, priced at 108,000 yen and aimed at use from the home to the studio, sported a birch semi-gloss black paint finish. With a somewhat large thick-walled cabinet and removable saran net, the NS-1000 weighed in at 39kg, 8kg heavier than the 31kg NS-1000M. As is evident from the difference in price, the cabinet finish of the NS-1000 was lavish enough to rival that of a luxury wood grain piano, but the fearless black design and overwhelming cost-performance of the NS-1000M made it the focus of popular attention. The upgraded NS-2000 released in 1982 and the NS-1000X released in 1986 reinforced the reputation of the original machine, and in the 23 years until the end of all beryllium diaphragm unit production in 1997 it was a long-lasting hit with more than 200,000 units sold.

YAMAHA GF-1 (1991) - Pure Beryllium and Active

 

active loudspeaker

The GF-1 from 1991 came to be known as an active speaker encapsulating an active crossover and a drive amplifier directly connected one-to-one with all speaker units. It was the culmination of the Yamaha HiFi speaker technology. It was designed with a two-part configuration (140 cm tall and 150 kg total) with the upper half housing a three-way speaker element and the lower half a YST superwoofer element. Its four drive amplifiers and active crossover units per channel were attached as four independent modules to the back of the superwoofer, and with a massive external power supply that itself weighed 25kg supplying each of the four amplifier modules with independent power it was a truly heavy piece of equipment. The crossover slope and cutoff frequency were completely fixed and could not be adjusted from the outside in any way, with only fine adjustments of up to ±2.5dB to each module’s input level available to the user. From this it can be seen that the developers intended the system to be perfectly tuned and did not intend the balance to be changed easily.

The 3 cm tweeter and 8 cm midrange were of course made of pure beryllium, but rather than using the vacuum deposition process of the past it went as far as using a forged beryllium dome developed for and used in only this model. Its pair of large and small woofers (27 cm bass and 30 cm YST sub-bass) likewise used a Kevlar cone and forged beryllium cap specific to this model, and the magnet utilized a voice coil with reduced diameter and dendritic crystal aluminum-nickel to lighten the motion of the diaphragm system. The tweeter and midrange magnets were also composed of dendritic crystal aluminum-nickel. The gold deposition method was performed on each unit’s diaphragm in an effort to damp the slight squeal of beryllium and produce uniform tone across all units. Overall it was built like it was meant to be the crowning glory, and if there was just one thing left undone it would probably be that it was not possible to use a forged beryllium woofer cone. As Yamaha’s speaker development changed course for a new era of focus on the home theater, the GF-1 put a period at the end of the pure beryllium development story that had played out since the NS-1000M.

In 1992 a dedicated 100W/ch Class A power amplifier, the GFD-1, with external power supply was introduced to complement the GF-1 loudspeaker. It featured a 6-position source selector and a 23-position rotary attenuator. It's construction made possible to be used with any passive loudspeaker not just the Active GF-1.

YAMAHA B-6 (1980) - Secrets of The Pyramid

power amplifier

Rare (truncated) pyramid shaped stereo power amplifier from Yamaha. At the heart of the Yamaha B-6 from 1980 is the so called "X-Amp" scheme. Initially known as "X-Power", this power scheme was first used in the Benytone X-Calibre lineup and the Carver lineup they were building at this time. It seems that Yamaha, as a later adopter, for some reason didn't implemented fully the Benytone/Carver technology so it was renamed "X-Amp". Basically this system is using a TRIAC which switches between high or low power supplies according to the input signal and output needs. This results in increased output power capacity, but some say that it is not necessarily a good sound too. (200 W/ch 8Ohm, THD: 0,003%, 10-100.000 Hz, 29 x 17,65 x 29 cm, 9,2 kg)

YAMAHA K-2000/K-1000 - α-ORBiT Optimum Recording

cassette deck

The K-2000 and K-1000 Natural Sound Cassette decks from Yamaha were introduced in 1982. They are thoroughly eqipped with uncomprimising technology, a combination of "spare-no-cost" engineering and innovative design. Both these decks are highly automated - thanks to built-in computers - providing an extensive range of features that are simple to use. Briefly, the K-2000 and K-1000 incorporate a speially designed two-motor, direct drive transport mechanism for smoth, silent precision, and three-head (sendust) reproduction system. Both decks employ a new Yamaha breakthrough - Linear Electromagnetic Transduction. This new system extends high signal transmission linearity to the actual point where a signal is transferred from the head to the tape - a previously uncontrollable area in the recording chain. 

Then there are double dbx and Dolby B noise reduction systems in the K-2000 and single dbx and Dolby B in the K-1000, ORBiT (Optimum Record Bias Tuning) for automatic, precise bias level setting, a 4-digit linear real-time conter, expanded-range LED level metering with peak hold, a number of auto/memory functions and more. The K-2000 additionally features a unique "monitoring erase" function and a broad-range pitch control. The Monitoring Erase function of the YAMAHA K-2000 is a highly original Yamaha feature that you won't find on any other cassette deck. While most modern cassette decks let you insert silences in a program being recorded by pressing a REC MUTE button, the K-2000 actually lets you selctively erase portions of a program while monitoring in the playback mode. This not only gives you much greater editing flexibility than provided by the REC MUTE function alone, but it allows you to record a program it its entirety and then edit later at your leisure - a particularly useful feature for editing timer-activated recordings made when you are away or asleep. Further accesiores include a wired remote and EIA rack mount adaptors.
