Professional Philips LHH-2000 CD-Player



Philips LHH2000 Professional CD- (or Compact Disc) Player System provids an exceptionally precise means for timing music selections during he creation of programmes using compact discs. The accuracy that the systems permits offers great advantages for both the network studios, in the production of live broadcasts, and the professional sound studio making pre-recorded programmes.



Professional Philips LHH-2000 CD-Player  


Up to three professional Philips LHH-2000 CD-Players can be operated within the system. These have been designed not only to provide the high standards of performance demanded by professional organisations, but also for compactness so that they fit unobtrusively into a busy sound studio. Each Philips LHH-2000 CD-Player is a mere 9,5" wide - just half the width of a normal rack-mounting unit.
The access capabilities of the professional Philips LHH-2000 CD-Players are considerably faster than those of a normal consumer unit. This is thanks to a special sensor that's built onto the focus unit of the laser optics system, which rapidly scans the disc for a desired point of access.
The professional Philips LHH-2000 CD-Player also features a high quality, built-in digital/analogue converter. It helps ensure the highest standards of reproduction required by studios - without the need for extra amplifiers. In addittion, the special built-in power supply unit handles all the needs of both Philips LHH-2000 CD-Player and the CD-Drive Control Unit.
As an aid to easy operation, the Philips LHH-2000 CD-Players are designed for top loading. This means that virtually no space is required in front of the unit when loading a disc. Thereby enabling a compact configuration to be achieved. A light touch on the lid, and the door to the disc drive compartment opens hydraulically. Once the disc is placed in position and the lid closed, the turntable mechanism starts rotating automatically.
On the front of the Philips LHH-2000 CD-Player illuminated indicators are provided which denote the status of the unit-on-line, ready, and power-on.

Philips LHH-2000 CD-Drive Control Unit  


The modulator microprocessor based CD-Drive Control Unit is made up from one function module and up to three command modules. Each module comprises a flat keyboard with an assocciated illuminated display panel. The selected configuration - a single-, dual-, or triple-CD-Drive Control Unit- can be used either free-standing, or flushmounted in a desk.

D/A (Digital/Analogue) converter circuit board whose transformer output stage ensures broadcast studio quality		RaPos (Radial Positioned) - the professional way to achieve very fast access times.

[s:6] [s:6] [s:6] 广播级的飞机——————Philips LHH0426







The Philips LHH0426 Universal Inspection Players forms the main part of a test system that enables extensive measurements on Compact Disc Masters, Shells, Stampers, and Replicas. Measurements can be taken automatically, and measured data presented in a variety of formats.

Modular construction
The Universal Inspection Player comprises three basic modules:
a. The opto-mechanical unit, which consists of the rotation motor, optical pick-up assembly, and the sledge, together with all related electronics. The unit is mounted on the upper part of the Universal Inspection Player on a base plate which is isolated against vibration
b. The servo-unit. This contains the electronics for the rotation-servo, radial-servo, focus-servo, servo-control, and the interface (including an IEC-625 remote control bus).
c. The decoder unit, which includes the basic decoder electronics and several slots for the installation of a variety of options.

Comprehensive capabilities
The audio signal quality of the Philips LHH0426 is determined by the properties of the decoder circuitry as, for example, errors on the disc could be masked by one decoder strategy and not by another.
The Universal Inspection Player gives the user the ability to verify the quality of Disc Masters, Shells, Stampers, and Replicas, using several different decoder strategies. The layout of the circuitry is such that changover from one decoder to another (different strategiy) is easily accomplished by exchanging a board in the decoder electronics unit.

The following decoders are available:
- Decoder based on a 7-frame strategy
- Decoder based on a 8-frame strategy, with oversampling DA-conversion (several adaptions make this ideal for error detection and counting)
- Decoder based on a 8-frame strategy

Available options include:
- Decoder controller interface with IEC-625 bus
- Subcode processing and interface
- Programmable error counting
- General purpose interface
- Analogue audio output
- Digital audio output

Player system configuration
A typical system configuration is illustrated. Here, the test program which is stored by the user in the memory of the IEC-bus controller, evolves fully automatically. Output of the measured data is possible in a variety of forms - as plots on the mutli-pen intelligent plotter; tables or forms on the printer; or volatile data on the screen of the controller. It is also possible to monitor specific analogue signals on a dual trace oscilloscope for evaluation of signal properties.
