The DSP33 Digital Loudspeaker System

Introduction

The DSP33 Digital Loudspeaker System incorporates the result of several years of research and development into innovative technologies.

Digital Signal Processing

Digital Signal Processing, or DSP, is a technique pioneered by Meridian in hi-fi products for achieving extremely accurate reproduction of audio signals using high-precision mathematical processing.

DSP allows sophisticated processing to be performed without any of the cumulative noise or degradation that inevitably occurs, even with high-quality analogue circuitry. In addition, the signal improvement techniques incorporated in the DSP33 would be virtually impossible to implement in analogue circuitry.

The DSP33 takes advantage of DSP for several different functions:

To remove timing variations from the incoming digital signals (de-jittering).

To split the frequency band between the treble and bass drivers (crossover).

To perform filtering or adjustment of the frequency response; eg treble or bass.

To provide volume control to 48-bit precision.

To provide bass extension by boosting the bass at moderate levels to take full advantage of the capabilities of the drive units.

If you are using the DSP33 Digital Loudspeaker System with a digital source, such as CD or DVD, the signals remain in digital form until the last possible stage.

DSP33 drivers

Each DSP33 loudspeaker uses two parallel 125mm (5") bass drive units. These incorporate a cast alloy chassis and a carbon fibre cone, and have a very large magnet which provides excellent drive and control. Combined with the Meridian’s active bass extension technology, they provide surprisingly rich, deep bass, quite unprecedented for this size of cabinet.

The treble unit is a very high quality 25mm (1") aluminium dome with a Neodymium magnet and a protective grille. It is extremely well matched to the woofer, and also tonally very compatible with the other speakers in the Meridian range.
