This uses a negligible amount of electricity, but ensures that the components of the loudspeakers operate at maximum efficiency from the moment you start. If you are not going to use the DSP8000 loudspeakers for several days you should switch each unit completely off at the back panel, and disconnect it from the AC power supply. To select a source · Press the appropriate source key on the remote; eg Radio. This will bring the DSP8000 loudspeakers out of standby, and the displays will show the currently selected source and volume setting. For example: Radio 65 By default the 12 sources shown below are available. As standard, all the sources are set to select the D1 digital input. To select the D2 input, see To configure a source, page 29.

Clipping; see Troubleshooting, page 33. 21 USING THE DSP8000 LOUDSPEAKERS Adjusting the volume The DSP8000 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. When you first connect power to the DSP8000 loudspeakers the volume is set to 65, which is similar to the midway position of the rotary volume control on a conventional preamplifier. To change the volume · Press the red A or V keys on the remote. As you adjust the volume setting the display will show the current volume level: Radio 55 To mute the sound · Press Mute on the remote. The display will show: Muted To restore the sound · Press Mute again on the remote. Alternatively, the sound will be restored if you adjust the volume. 22 USING THE DSP8000 LOUDSPEAKERS Changing the tilt, bass or phase The DSP loudspeakers provide sophisticated tilt 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. The controls are more subtle than conventional tone controls, and take advantage of digital signal processing techniques to provide a more natural adjustment of the frequency response. You can also change the absolute phase of the signal, to compensate for signals which are out of phase, giving an unnatural-sounding bass. To change the tilt · Press < or > until the display shows the current tilt. For example: · Press A or V to change the tilt. The tilt control tilts the frequency of the response over the entire frequency range to make the sound brighter or dimmer. It can be adjusted between ±10db in 0. 5dB steps. Normally settings between +1. 0 and -2. 0 will give the most natural results. Tilt+0. 0 To change the bass · Press < or > until the display shows the current bass setting. [. . . ] This determines the configuration of all digital loudspeakers in the system. Unit stays in standby · Check that it is connected correctly. · Turn the system on from another Meridian product in the system. Only the master loudspeaker plays · Check the S5 cables are connected correctly. Sound is odd or mono · Check that the DSP8000 loudspeakers are correctly configured as Left and Right respectively. The yellow indicator flashes or stays on This indicates that DSP clipping is occurring. Brief flashes indicate occasional clipping which will not be audible. If the indicator stays on for long periods this may indicate a fault in the configuration of your system, and you should contact your Meridian dealer. 35 TROUBLESHOOTING Maintenance and cleaning Fitting and removing the grilles When fitting the grilles ensure that the two cutouts are at the 3 o`clock and 9 o`clock positions, as this will align the pattern on the grille fabric correctly.
