User manual MERIDIAN DSP8000

[. . . ] DSP8000 Digital Loudspeaker System User Guide ii Preface Important safety instructions Read the instructions. This apparatus has been designed with Class 1 construction and must be connected to a mains socket outlet with a protective earthing connection (the third grounding pin). The apparatus may be isolated from mains power either by unplugging the power connector from the rear of the unit, or by unplugging the connector at the opposing end of the power cord or cable from its supply outlet. As a result, either or both of these connectors should remain accessible. [. . . ] In addition, three coloured indicators show status information. Using the DSP8000 loudspeakers To change the displayed information · Press Display. Pressing Display steps between the following options: Display option Source and volume Meridian source display (dashes if not present) Audio format Blank Example Radio65 ---PCM96k The audio format display shows PCM, Data, or MHR, followed by the frequency or NL (not locked). Status indicators The display includes the following status indicators: Indicator Red Yellow Green Description Master loudspeaker. Thermal protection; see Troubleshooting, page 31. 20 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 A or V volume keys on the remote. As you adjust the volume setting the display will show the current volume level. For example: Radio55 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. 21 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. 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. The bass control allows you to adjust the bass response in the room by ±5dB in 0. 5dB steps. Normally settings between +3. 0 and -2. 0 will give the most natural results. Using the DSP8000 loudspeakers To change the absolute phase · Press Function < or Function > until the display shows the current phase. For example: Phase+ If you have a Meridian Surround Controller these functions are performed via the surround controller. · Press Function A or Function V to change the phase. To change the treble · Press Function < or Function > until the display shows the current treble. For example: Tre. +0. 0 · Press Function A or Function V to change the treble. The treble control tilts the frequency of the response over the entire frequency range to make the sound brighter or dimmer. Normally settings between +1. 0 and -2. 0 will give the most natural results. To change the bass · Press Function < or Function > until the display shows the current bass setting. For example: Bass+0. 0 · Press Function A or Function V to change the bass. 22 Using the DSP8000 loudspeakers Changing the listening position The balance control of the DSP8000 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. The axis control allows you to adjust the optimum listening height of the DSP8000 loudspeakers, like a balance control operating in the vertical plane. The axis can be adjusted between 3 and -2, where 0 corresponds to the axis of the treble unit. Usually a listener will be below that position, so we recommend settings of -1 or -2. If you have a Meridian Surround Controller these functions are performed via the surround controller. To change the balance · Press Function < or Function > on the remote until the display shows the current balance. For example: Bal. <0> · Press Function A or Function V to change the balance. The display shows the direction and position of the listening position. [. . . ] · If the problem persists contact your dealer. Unit stays in standby · Check that it is connected correctly. · Turn the system on from another Meridian product in the system. Remote not working Check the following: · The battery in the MSR+ remote. · See if the DSP8000 loudspeaker has been set up as not controller in the Meridian Configuration program; see Configuring the setup options, page 28. Note that this may be deliberate by your dealer. Only the master loudspeaker plays · Check the cables are connected correctly. Sound is odd or mono · Check that the DSP8000 loudspeakers are correctly configured as Left and Right respectively. Configuring the DSP8000 loudspeaker does not have any effect Make sure that you are configuring the DSP8000 loudspeaker used as the master digital loudspeaker in the system. [. . . ]
