Quad CDP-2 CD player

The Quad 99 CD-P is a versatile CD player with several advanced features. The CD-P will play regular music CDs, music and standard CD-Rs (open or closed) and CD-RWs. Automatic upsampling increases the detail levels in your CD collection, and the ability to add three digital and three optical sources enables you to get the very best from your other digital media. An optical output is provided to connect the CD-P to other digital equipment.

The CD-P accepts three optical and three digital inputs. Minidisc and DAT players, or Digital Audio Broadcast tuners (DAB) will be significantly improved by connecting their digital outputs to the CD-P. The CD-P can accept incoming PCM digital signals to a maximum resolution of 24bit/96kHz.

CD Mechanism

The Quad CDP-2 mechanism was a major engineering project. Whereas most manufacturers use off-the-shelf transports, we wanted a unit which was particularly optimized to static CD players and employed a ‘lazy servo’ mechanism. In all off-the-shelf CD mechanisms – even those used by high-end manufacturers, there are a number of compromises built into the device which mean that they can be used for a number of applications. With a new Quad mechanism, it could be safely assumed that the CD player would be sat on a farily rigid structure and vibration, whilst possible would be limited.

This enabled us to develop a proprietary ‘lazy servo’ mechanism, which involves the way the transport deals with disc data loss. Where most transports, upon loosing a data stream, move the optic (laser) back a forward rapidly to recover the lost data – ours just sits there and waits for the disc to come around. This has a significant benefit in lowering the noise floor of the player. Some innovative timing techniques used, also result in an industry leading jitter measurement of just 8 pS. These technical innovations combined with its versatility of use (particularly the 6 digital inputs and adjustable level output) make the CDP-2 one of the finest CD players on the market today at any price.
