CLASSIC CD PLAYER

The Classic CD player is in fact the renowned CD50mk2 in new casework to partner the Classic 5350SE integrated amplifier.

The player uses a ROM drive which replaces the Philips CDM12 transport which Creek had used previously.  Extracting the digital information from the ATAPI bus, similar to a computer, has enabled Creek to work with a virtually jitter free signal source. To convert the signal to a usable format, the Classic uses a digital buffer circuit (FPGA) that stores the signal for a short time and converts it into a suitable format for feeding to a DtoA converter. This creates shock immunity from the player, so that the disc is not playing exactly in real time, but slightly delayed through the dynamic buffer. It also converts the signal into a SPDIF signal to provide a high quality digital output, which is now available via TOSLINK optical as well as co-axial sockets.

Soft upgrades are made easy in the Classic CD player. The buffer and microcontroller are both programmed by separate EPROM’s that contain all the code. To upgrade the code, Creek will supply a new EPROM that can be plugged into the motherboard to replace the existing one. The player will ‘boot load’ the new software upon start-up.

Sound quality on the Classic is superb.  With an improved and symmetrical layout with shorter signal paths, the Classic has much better measured performance than its predecessor, with signal to noise and THD figures much lower than on the CD50. This is due to the player having distributed power supplies with 7 digital and 5 analogue low noise voltage regulators and low noise resistors. A higher frequency clock oscillator is used in this player and is synchronised with the micro controller and buffer clock to minimise internal interference. Two separate high current mains transformers are used in the Classic. The voltage to the digital and analogue circuitry, display and ROM drive are kept completely separate, for maximum interference immunity.

Front panel controls include Play, Stop, Pause, Open/Close, Skip Forward, Skip Back, Search Forward, Search Back, Shuffle, Repeat and Standby functions. They are supplemented by an attractive full feature Creek SRC2 system remote control handset utilising RC5 type codes.

The rear panel has a mains switch, together with the usual fused IEC mains inlet. A pair of gold plated Phono/RCA sockets is provided for un-balanced analogue output and (SPDIF) digital outputs are via a transformer coupled Phono/RCA socket.

The Classic player has been designed to read all known ‘Copy Protected Discs’ that currently exist. In future, CPD’s with revised copy protection algorithms may cause problems, but with its upgradeable software and firmware capability, the player can be easily upgraded by the dealer or importer to play such discs.
