DSP33 and DSP33C Digital Active Loudspeakers
The new DSP33 Digital Active Loudspeaker is a remarkable combination of unique Meridian technologies
in a compact package. The result is a loudspeaker which is elegant, articulate and versatile - high
technology and high fidelity. The DSP33 is deceptively small. Its bass extension is startling for its size and
fully controlled. It projects a dramatic soundstage - detailed yet smooth, grand yet intimate.
The DSP33 is packed with the very latest in audio technology for the new generation of high resolution
sources.
Signal Processing
The DSP33’s two digital inputs can accept up to 96kHz/24bit sources, including Meridian High Resolution
(MHR) streams from Meridian Processors and DVD players.
The unique Meridian DSP processing is performed on a brand new 100 MIPS Motorola DSP, the 56364.
Like the other members of the Meridian DSP Speaker family, the DSP33 Signal Processing includes
·
·
·
·
·
FIFO memory buffer input for the lowest possible jitter from almost any source
Linear-phase crossover for precision drive unit integration not possible with analogue techniques
Tweeter delay for perfect driver alignment
48-bit resolution volume control
Minimal frequency equalisation to give a frequency response free from drive unit or electronic
colouration
·
·
Transparent tone controls
Absolute phase control and phase-corrected balance control
The extraordinary big box sound of the DSP33 is achieved using exciting new signal processing
developments. Meridian’s active bass extension deepens the response without excessive woofer
excursion. At moderate volumes, a psychoacoustially correct extension filter extends the bass still further.
At high volumes DSP bass protection helps prevent the woofers from bottoming. Only the very lowest
frequencies are reduced.
Electronics
The electronics of the DSP33 are designed using the very
latest techniques. Extensive use of 4 and 6 layer PCBs and
surface mount components allow the hardware of Meridian
DSP Loudspeakers to be compacted into this cabinet without
compromise.
Components are carefully chosen and include many
polypropylene capacitors and Van den Hul internal wiring.
The DACs are the very latest 96kHz/24 bit devices.
At the heart of the DSP33 are the twin amplifiers, which make
use of our latest research into idealised low feedback
amplifier design. These give high power - 85W Bass and
65W Treble. Careful attention to star earthing and high speed
bipolar output devices combine to give very fast bass and
high resolution. The system has extremely low levels of noise
and distortion. The power supply includes a substantial
torroidal transformer and audiophile grade capacitors.
