2 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.
3 INTRODUCTION Power amplifiers The speakers are driven by multiple independent high-power, low- feedback power amplifiers. The combination of idealised magnetic design, careful star earthing, and very fast output devices gives the amplifiers extremely low noise, high detail, and fast bass.
4 INTRODUCTION Meridian Comms The Meridian DSP loudspeakers are part of the Meridian family of advanced digital, analogue, and video components, and these incorporate a sophisticated communications link, to allow you to control any combination of units using a single remote, and ensure that they will work together as a fully integrated system.

14 SETTING UP THE DSP LOUDSPEAKERS Unpacking Before you begin installation you should ensure that your DSP loudspeakers are the correct voltage for your local AC supply.
15 SETTING UP THE DSP LOUDSPEAKERS Caution (DSP6000 and DSP6000C only) Meridian Audio has taken every care in the design, assembly, finishing and packing of this product. The high gloss finish on parts of the cabinet is achieved by painting up to five coats of polyester lacquer onto the plywood, each one hand polished.
16 SETTING UP THE DSP LOUDSPEAKERS • When all four feet have been fitted, carefully set the DSP loudspeakers upright in their playing positions and remove the rest of the packaging. To fit the rubber bumpons (DSP5000C and DSP5500HC only) • Attach four bumpons to the underside of each speaker, using the self- adhesive pads.
17 SETTING UP THE DSP LOUDSPEAKERS Radio interference FCC Warning: This equipment generates and can radiate radio frequency energy and if not installed and used correctly in accordance with our instructions may cause interference to radio communications or radio and television reception.
18 SETTING UP THE DSP LOUDSPEAKERS Positioning the digital loudspeakers Safety warnings • Do not expose the speakers to dripping or splashing. • Do not place any object filled with liquid, such as a vase, on the speakers. • Do not place naked flame sources, such as lighted candles, on the speakers.

24 USING THE DSP LOUDSPEAKERS Selecting a source When not playing, the DSP loudspeakers should be left in the standby state. This uses a negligible amount of electricity, but ensures that the components of the loudspeakers operate at maximum efficiency from the moment you start.
25 USING THE DSP LOUDSPEAKERS Changing the display The DSP loudspeakers display information about the current settings on the 8-character front-panel display. In addition, three coloured indicators show status information. To change the displayed information • Press Display .
26 USING THE DSP LOUDSPEAKERS Adjusting the volume The DSP loudspeakers adjust the volume in precise steps of 1dB, where 9dB is equivalent to doubling the loudness, and can be varied in the range 1 to 99dB.
27 USING THE DSP LOUDSPEAKERS Changing the treble, bass, or phase The DSP loudspeakers provide sophisticated treble and bass controls, to allow you to adjust the broad balance of the system to correct for the acoustics of your listening room, or for a misbalanced recording.
28 USING THE DSP LOUDSPEAKERS Changing the listening position The balance control of the DSP loudspeakers uses digital signal processing to compensate for an off-centre listening position by delaying and diminishing the sound in one speaker, thus effectively shifting the speaker’s image back.
