INTRODUCTION
Meridian DSP loudspeakers
Meridian DSP loudspeakers represent the fruits of more than 25 years of
continuous development of loudspeakers as musical instruments. The finest
materials and state-of-the-art design are combined to create what we
believe is the ultimate range of home loudspeakers.
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 Meridian DSP loudspeakers would be virtually
impossible to implement in analogue circuitry.
The Meridian DSP loudspeakers take advantage of DSP for several different
functions:
•
To remove timing variations from the incoming digital signals
(de-jittering).
•
To split the frequency band between bass, mid-range, and treble 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 digital protection of the loudspeakers against high-level low-
frequency transients.
•
To perform electronic equalisation.
If you are using the Meridian DSP loudspeakers with a digital source, such
as CD or DVD, the signals remain in digital form until the last possible
stage.
DSP loudspeaker drivers
Each DSP loudspeaker uses multiple high-efficiency long-throw custom
drive bass units.
Each treble unit is a very high quality 25mm (1") Meridian piston in a short
horn, using an aluminium dome with a silver voice-coil. It is extremely well
matched to the woofers, and also tonally very compatible with the other
speakers in the Meridian range.
