JVC XL-Z1010NT CD player

Compact Disc Player - K2Interface. Revealing possibilities at the source

Changing the digital code on a CD into music requires that a digital-to-analog converter choose 1 of 65,536 possibilities every 1/44,100th of a second.

It's commonly assumed that digital signal is composed of 1's and 0's, each represented by the presence or absence of a square-shaped pulse. But the fact of the matter is, a digital signal contains ripple - a type of distortion that changes the shape of a waveform - and jitter, components that move the timing of a pulse forward or behind.

These "non-Code" components can result in a sound that differs from the intent of the digital source. The K2 interface solves this problem by completely regenerating the digital signal. At the heart of the K2 interface is essentially an ultra-high-speed camera with a shutter speed of 20 nanoseconds (20 billionths of a second). Based on these quick snap-shots, it recreates the digital signal as a perfect square wave.

Providing a perfect signal to the D/A converter allows for accurate reproduction of all the nuances such as sound staging and depth. As a matter of fact, in many ways both frequency range and dynamic range are expended. High frequencies sound clearer. There is a heightened sense of the power in the mid-to-low-frequency range.

Music seems to acquire more depth and width, providing clear images of instruments and voices. Overall, sound is smoother and more natural across the audio spectrum.

Precision D/A Converter System Using Four D/A Units.

The XL-Z1010TN features two D/A converter units for each channel - four in all. There is a 16-bit converter for the most significant bits and a 2-bit converter for the two least significant bits. Since the least significant bits have greatest bearing on the sound quality at low level, JVC uses an elaborate discrete D/A converter system for these bits to ensure higher precision. All four converters operate with 18 bits "full Time" whether the level is high or low. Our "quadruple full-time linear 18-bit combination D/A converter" allows you to enjoy digital sound at its most delicate and dynamic.

JVC AX-Z1010TN amplifier

Digital Pure-A. New possibilities for class-A

There's no doubt an amplifier operating in class-A mode provides lower distortion and cleaner sound than those in popular class-B or class-AB. Their inefficiency, however, makes class-A amplifiers require elaborate heat sinking, and still the amps waste much of their power in the form of heat. This results in inflated cost and relatively low power output. But to enjoy the dynamic sound of digital programs, you need a lot of power.

How to combine the low-distortion sound of class-A with efficiency and power demended by digital audio?

Enter the Digital Pure-A Type II

JVC has the solution - the Digital Pure-A Type II circuit featured in the Ax-Z1010TN "Digital" Integrated Amplifier. This ingenious design takes the advantage of the fact that digital signals can be stored in memory temporarily without changing their frequency response or phase response.

In the Digital Pure-A Type II, digital signals fed directly from digital equipment are split into two: the main signal and the "prediction" signal.

The main signal is sent to a time base processor where it's stored in memory for a fraction of a second before it goes to the D/A converter. The prediction signal is sent to the bias circuit to optimize bias applied to the power transistors depending on dynamics of the upcoming signal. What you get out of this is low-distortion class-A sound with high efficiency and high power.

The AX-Z1010TN is a "Digital" integrated amplifier incorporating a D/A converter system complete with the K2 interface, 8-times oversampling and quadruple D/A converters.

And the amp features a special design for analog programs too - Opt Super-A, another JVC exclusive combining low distortion and high efficiency.

Stax CDP Quattro II CD player

Super High Resolution Compact Disc Player

 

Advanced DA conversion and 8-times oversampling/18-bit digital filtering bring to life the full potential of the 44,1 kHz, 16-bit CD format as never before. Its high fidelity and complete lack of coloration or "digital harshness" make this the CD player for analog diehards.

By no mean are all CD players that feature 18-bit processing and 8-times oversampling alike. The Stax technology and know-how that go into the Quattro II mean more polish and overall audio output closer than ever before to the ambience of a live performance.

Terminal facilities like a Direct Out with no analog filter and a buffer-equipped Variable Out represent the absolute state-of-the-art. In digital audio technology.

But more revealing than any discussion of the technical merits of this unit will be a listening test with your favorite CDs played on the Stax Quattro II CD player.

Sugden A28 amplifier

The Sugden A28 once again gives you the unsurpassed quality of pure Class "A"

This is how we regard the Sugden A28 amplifier. Based upon well proven Sugden output circuitry, we now bring you an Amplifier which is second to none in its sound reproducing quality.

Let's start with the input circuitry, accessed via easy to use phono plugs and sockets and selected by four simple push-on, push-off switches. On the disc input not only do we have the facility for an internal plug in Moving Coil Module (the A 28 CTHA) deriving its power from within the Amplifier, but also a brand new "series-shunt" disc Amplifier with precision RIAA equalization and two level gain adjustment. In fac, everything to suit the cartridge of your choice.

Next the Tuner, Auxiliary and Tape inputs. All these three have identical input impedances, allowing a wide range of ancillary equipment to be used without interface problems.

The Tape output signal can, of course be fed from any of the input signals. For those people with 3 head Tape Machines, the Tape button will allow immediate post tape recording/replay through the Amplifier, i.e. Tape Monitor.

 

No tone controls here to marr distortion figures, just volume and balance controls with simple but effective filter circuits for hiss and rumble attenuation. Don't forget the Mono Button. Still essential for much recorded material.

Observe the neat, unfussy and easy to clean case style. Front and rear sections are matt black extrusions, whilst the side and top plates are covered in grey textured "Nextel" paint, giving a very attractive two tone finish.

As to how it sounds, well the specification, amy give you some clue, but we believe you will be delighted at the clear transparent sound.

The very low harmonic distortion of a class "A" Amplifier gives fatigue free listening to please even the most discerning ear. All this and more. Sugden expertise brings you the "S.Q.C" circuitry to give an amazingly compact pure class "A" output stage with up to 35 watts in class "B" allowing all but the most inefficient loudspeakers to be driven. Backed by the Sugden workmanship for life guarantees, we are justifiably proud to present this high quality British product.

S.Q.C. is short for Switched quiescent Current

And its development gives new potential to the cless "A" amplifier. We at Sugden have always believed in the class "A" amplifier and , in fact, were the first company in the world to produce the all transistor class "A" amplifier in 1968. it was only the demand for more output power which forced us away from the 12 watt A21 pure class "A" amplifier into the higher power "AB" amplifiers, such as the A48 and the P51 in the majority of casses were music is played through reasonably efficient 8  loudspeakers, the average power used is probably not more that 3 to 4 watts with excursions to higher levels depending upon the dynamic rrange of the recorded material.

Also what is the point of burning off power when it is not required. This then is the philosophy around which the S.Q.C. circuit has evolved. The availability of high speed, low level, switching components enables us to control the "AB" circuit to its very best advantage.

The A28 operates continuously at a quiescent level of 10 watts in Class A, i.e. with a current in the output transistors of about 800 mA. By looking at the incoming signal level, after the potentiometer, we can determine whether the 10 watt output level will be exceeded and should this be the case increase the quiescent current level up to 1,2A or 20 watts. The current will stay at this level for as long as the heavy signal exists and also for a short time afterwards, before reverting back to the lower quiescent level. There is, however, a finite switching time of the S.Q.C. circuit, admittedly it is only about one millionth of a second, but under some very fast transient signal conditions there is just a possibility that if the switch sensing point is set at the same level as the quiescent current level, the Amplifier may slip momentarily into class "B" before reverting back to class "A". This is obviously unacceptable and in order to prevent it, we set the sensing a elactronics to switch at a level of 7 watts allowing a 3 watts reserve, giving time for the output stages to react to the increased demand.

Using this technique we can absolutely guarantee a full 20 watts in class "A" at all times.

The additional overhead level between 20 and 35 watts in class "B" allows for the wide dynamic range of some recorded material and since it is far into the linear range of the devices, there is little increase in distortion right up to 35 watts.
