Meridian DSP6000 User manual

Background
Meridian has long led the market with their highly acclaimed DSP loudspeaker
designs. In fact the DSP6000–which was introduced in 1990–is the only
loudspeaker to hold the coveted Stereophile Class A rating for eight successive
years.
The Meridian DSP loudspeakers combine excellent acoustic and drive-unit
technology, with multiple built-in power amps and unique performance-
enhancing DSP and digital conversion systems. The DSP loudspeaker is the
ultimate expression of the speaker builder’sart.
Meridian DSP6000 and DSP6000C
“Smart Art” is how one owner, an antiques dealer, describes DSP6000s. Their
clean, classic lines and hand-rubbed piano lacquer blend into any decor, and
belie the fact these slim columns house an advanced home music system: a
technical tour de force comprising twelve drivers, eight amplifiers, eight digital
converters and crossovers, and advanced sound-shaping computers, all self
contained, remote-controlled and requiring no speaker wires.
Computers acoustically blend thetweeter, midrange and woofers; the benefit is
much better three-dimensional music than any conventional hi-fi can offer in
stereo or surround modes.
Indeed, DSP6000s will place musicians in precise locations in your room, with
even subtle body movements clearly audible, such as a singer swaying or an
instrumentalist stepping up for a solo. Voice and instrument timbre are utterly
natural. The bass plays lower than most humans hear, but you can feel it. The
highs are smooth and sweet. Music sounds balanced and articulate, with clarity
and tiny detail even at low volumes. And the system is easily muscular enough
to effortlessly place a live orchestra or rock band in your room.
In audiophile terms the DSP6000 accepts only digital inputs; its digital
crossovers are phase-coherent at all points, impossible with traditional design;
each driver band has a dedicated DAC; computers apply digital signal
processing for exceedingly advanced control features; the eight amplifiers
assess drivers as part of the electrical circuit for remarkably distortion-free
behaviour.
