Precision CD Playback

The quality of a digital audio system begins with an accurate source. The QUAD 3CDT has been engineered to read the information stored on your CDs with exceptional precision. Its high precision CD mechanism works together with a custom designed servo control system to maintain stable disc operation and minimise read errors.

Rather than incorporating a built in DAC, the QUAD 3CDT is dedicated exclusively to transport duties. This allows the design to concentrate on extracting and delivering a clean digital signal without unnecessary analogue circuitry.

For listeners searching for a high end CD transport or a dedicated CD transport for an external DAC, this focused architecture makes the QUAD 3CDT an ideal choice.

Advanced Servo and Clock Technology

The QUAD 3CDT incorporates an advanced CD servo and control architecture built around a high performance 32 bit RISC CPU and a dedicated MCU. This dual core processing framework provides precise control over disc access, servo operation and error correction.

A temperature controlled ultra low jitter crystal oscillator provides the master clock for the servo and decoder section. The oscillator is powered by an independent low noise supply and grounding arrangement, providing a highly stable timing reference for the digital signal.

This carefully controlled clocking architecture helps minimise timing errors and jitter, contributing to cleaner transients, precise imaging and a more coherent presentation.

Carefully Designed Power Architecture

Power supply design plays an important role in digital audio performance. The QUAD 3CDT uses a carefully engineered internal power architecture designed to separate sensitive digital circuits from sources of electrical interference.

The motor and laser servo circuits are isolated from the decoder section responsible for retrieving the digital audio information. This helps prevent unwanted interference from affecting the digital signal path.

Three independent low noise voltage regulator circuits are dedicated to the CD servo, while the TCXO clock circuit uses an ultra low noise linear regulator. Together, these design elements provide clean and stable power to the critical sections of the transport.

Designed for the QUAD 3 DAC

The QUAD 3CDT is designed to work seamlessly with the QUAD 3 DAC, creating a complete digital playback system for CD enthusiasts.

By separating the transport mechanism from digital to analogue conversion, the QUAD 3CDT allows the DAC to focus entirely on converting the digital signal into high quality analogue audio. This combination creates a clean and carefully controlled signal path designed to reveal the detail, dynamics and musical character contained within your CD collection.

The result is a highly capable digital front end with excellent clarity, imaging and musical expression.

Wide Format Compatibility

Although designed primarily for standard audio CDs, the QUAD 3CDT offers support for a variety of disc and digital file formats.

It supports standard CDs as well as CD R, CD RW and data CDs. Compatible digital audio formats include FLAC, WAV, WMA, MP3 and APE.

This flexibility makes the QUAD 3CDT suitable for listeners with both traditional CD collections and discs containing compatible digital music files.

Classic QUAD Design

The QUAD 3CDT combines modern digital engineering with the understated design language that has become synonymous with QUAD. Its front panel shares the elegant proportions and detailing of its amplifier and DAC siblings, making it an excellent visual match for a complete QUAD system.

The internal transport mechanism is also shielded against vibration and electrical interference. From the precision disc mechanism and tray to the digital output stage, every component has been designed with reliability, quiet operation and long term performance in mind.

Why Choose the QUAD 3 CD Transport?

The QUAD 3CDT is an excellent choice for anyone who wants to continue enjoying physical CDs while upgrading the digital front end of their Hi Fi system.

Its dedicated transport design, precision servo system, ultra low jitter clock and carefully isolated power architecture make it far more than a basic CD drive. When connected to a high quality external DAC, it provides a sophisticated digital source capable of extracting the full potential from your CD collection.

For owners of the QUAD 3 DAC, it is an especially natural partner, offering a visually and technically matched solution.

Frequently Asked Questions of the QUAD 3 CD TRANSPORT

Is the QUAD 3CDT a CD player?

No. The QUAD 3CDT is a dedicated CD transport. It reads the digital information from a disc and sends the digital signal to an external DAC through its digital output. A separate DAC or compatible digital amplifier is therefore required for analogue audio output.

Does the QUAD 3CDT have a built in DAC?

No. The QUAD 3CDT does not include a digital to analogue converter. Its purpose is to provide a clean and accurate digital signal to an external DAC, such as the QUAD 3 DAC.

What discs does the QUAD 3CDT support?

The QUAD 3CDT supports standard CDs, CD R, CD RW and data CDs.

What music file formats are supported?

Compatible formats include FLAC, WAV, WMA, MP3 and APE.

What is the benefit of using a dedicated CD transport?

A dedicated CD transport focuses exclusively on reading the digital information stored on a disc and delivering it to an external DAC. This allows the transport and DAC to perform their respective functions independently and provides greater flexibility when building a high quality digital audio system.

Is the QUAD 3CDT suitable for other DACs?

Yes. Although it is specifically designed to complement the QUAD 3 DAC, the QUAD 3CDT can be integrated into other high quality digital audio systems that accept its digital output.

Does the QUAD 3CDT support high resolution digital files?

The transport supports FLAC, WAV, WMA, MP3 and APE files from compatible data CDs. Its primary purpose, however, is high quality CD transport operation.
