Philips LHH1001 CD drive


A canon in which the preceding travel melody is strictly imitated by the other melodies that follow. The canon consists of a piece of music in which the preceding travelling melody is rigorously imitated by the other melodies that follow. The most distinctive feature of the canon, which originated some 700 years ago and culminated in Bach's instrumental music, was its strict regularity. The act of picking up the music signal by precisely tracing the rows of pits engraved on the CD has something in common with this canon technique.

Reference CD player

The Philips LHH1001, the CD drive unit of the Philips LHH1000 system, faithfully embodies the CD drive and signal pick-up ideals of CD developer Philips. The CD drive mechanism is built around a solid aluminium die-cast base, with a pot-plated die-cast chassis and die-cast side panels for high openness and high weight, and pot-plated shield covers for anti-spurious measures.

Philips LHH1000 LHH1001 CD Drive

By enhancing the precision of each part, the disc is driven with precision to any extent and picks up high-purity music signals. The Philips LHH1001 CD drive unit achieves this with unparalleled precision.

The Philips LHH1001 CD drive is equipped with the Philips CDM-1, the origin of CD drive mechanisms and made of die-cast aluminium, achieving a high level of reliability.

To pick up accurate signals, the CD pits must be traced reliably. The playability of the disc itself can easily clear scratches and dust, and error-free, high-precision signal reading is the basis of high-purity music reproduction.

The CD drive unit Philips LHH1001 uses as its CD drive mechanism the Philips CDM-1, which is also used in the professional CD player Philips LHH2000. The Philips CDM-1 is constructed entirely from die-cast aluminium, including the mechanism chassis. The Philips CDM-1 is a CD drive mechanism that fully exploits the superior tracing ability of the Philips swing-arm big-up. The strong die-cast aluminium unit eliminates external vibrations, and when open, the spindle motor rotational vibrations are also powerfully activated, freeing the pickups from the effects of various vibrations. The swing-arm pick-up, with its excellent dynamic balance and high intrinsic tracing ability, enables even more precise operation and highly accurate reading of the music signal.

The Philips LHIH1001 drive unit is a rigid structure with a copper-plated die-cast chassis and die-cast side panels, which supports the CD drive mechanism CDM-1 with high rigidity.

The Philips LHH1001 has a copper-plated die-cast chassis and die-cast side panels. It supports the CD drive mechanism Philips CDM-1 with high rigidity and further accentuates its high-precision signal pick-up. In addition, die-cast parts ensure high rigidity. The Philips CDM-1 is also equipped with die-cast parts to increase rigidity and weight, a three-piece aluminium top cover, cement-filled die-cast legs and large insulators with rubber spacers, and other features. The entire body is vibration-free and resonance-free thanks to the three-piece aluminium top cover, cement-filled die-cast legs and large insulators with rubber spacers. The mechanism is designed to operate the rotary thread and laser pick-up with excellent precision.

The Philips LHH1001 CD drive unit handles only digital signals as signals. In the digital domain, the quality of the power supply is often considered negligible, unlike in analogue. However, the digital signals handled by the Philips LHH1001 handles digital signals as musical information itself, and by increasing the precision of each part to the utmost limit, the signals are read with unmatched accuracy.

The Philips LHH1001 is equipped with a large toroidal transformer with excellent regulation and a powerful power supply section comparable to that of a high-power amplifier. In addition, the signal and circuitry circuits are separated by separate circuit boards, and pot-plated shield covers are used to completely eliminate mutual interference. High-precision signal transmission is pursued to the highest degree. In addition, all parts used are carefully selected top-grade parts, and thorough measures are taken, such as the use of vibration-resistant glass-epoxy substrates.

Philips LHH1002 D/A converter


A fugue is a piece of music in which the monotone theme presented at the beginning of the piece is the centre of the composition, and multiple melodies are repeated, crossed out or overlaid with incidental melodies. The heyday of the fugue, which lasted about 100 years and culminated in Bach's 'Technique des Fugues' and 'Mean Clappier', was marked by the development of a variety of imitations and counterpoints based on the canon.

Philips LHH1000 LHH1002 D/A converter

It was a period in which counterpoint developed and a great artistic flowering took place. From canon to fugue. That artistic leap was nothing more than the sign of 0s and 1s.

It is reminiscent of D/A conversion, where digital signals are transformed into beautiful music. The Philips LHH1002 D/A converter unit of the reference CD player system Philips LHH1000 is equipped with the "A-version", an even higher performance version of the 16-pit 4x oversampling digital filter that was pioneered by CD developer Philips.

The D/A conversion accuracy has been improved to the limit. Furthermore, the sound quality has been meticulously improved by thorough spurious countermeasures and power supply reinforcement.

Digital filter

One of the technologies that has enabled the Philips LHH2000 to achieve its superior musical reproduction capability is the 4x oversampling digital filter, which Philips has been researching since the early days of CD development. With advances in digital technology, Philips has pioneered the 16-bit quadruple oversampling digital filter. Now, Philips has developed a new 16-bit oversampling digital filter with improved matching between the digital filter and the D/A converter for the ultimate in precision. 16-bit 4x oversampling.

The Philips LHH1002 is equipped with a specially selected silver crown S1 of the Philips TDA1541 A. Together with the excellent phase characteristics of the traditional L/R independent 2-DACs, this realises D/A conversion with overwhelmingly high accuracy, reproducing fading pianissimo with rich emotion.

Inheriting the design concept of the LHH2000 - Fully balanced output circuit with outgoing transformer.

The Philips LHH1002 inherits the design concept of the Philips LHH2000 and is composed of exactly the same circuit with an output transformer and parts that incorporate the latest technology. The balanced output circuit using an output transformer extracts all the audio signal from 20 Hz to 20 kHz and cuts out unnecessary bandwidth. Its rich, smooth sound is a perfect successor to the Philips LHH2000's unrivalled ability to reproduce music in terms of musical expression.

The Philips LHH1002 is a D/A converter unit that constitutes the Philips LHH1000 as a system unit. In addition to the CD drive unit Philips LHH1001 and other CDs, digital signals from DATs, BS (satellite) tuners, etc. can be input and enjoyed with the same high-grade sound as the Philips LHH1000.

The unit is equipped with a jitter absorption circuit to deal with jitter (signal fluctuation with respect to time), which is a problem in optical transmission. Signals containing jitter caused by vibrations in the fibre-optic cable are pooled in the IC and extracted in the correct jitter-free cycle. As a result, an overwhelmingly low weight is achieved over the entire bandwidth.

Sound quality is pursued down to the smallest detail, including a powerful power supply section with three toroidal transformers and thorough spurious countermeasures.

The Philips LHH1002 is equipped with dedicated power supply units for the digital, D/A converter and analogue circuits. Each power supply is reinforced with a toroidal transformer with excellent regulation. Dedicated power supplies are also installed.

In addition to the dedicated power supply, each circuit block is separated as a separate board and is covered with a copper-plated shield to thoroughly eliminate mutual interference and improve the purity of the sound. Other details include a copper-plated die-cast chassis and die-cast side panels to eliminate the effects of vibration, and a glass-epoxy board with a printed pattern made of copper foil twice as thick.
