Introduction
DSP5200 and DSP5200HC DSP5200 and DSP5200HC This chapter explains how to unpack and install the DSP5200 and DSP5200HC, and gives specifications.
DSP5200 and DSP5200HC Unpacking Before you begin installation you should ensure that your DSP loudspeakers are the correct voltage for your local AC supply. If they are not, do not try to install them, and contact your dealer. You should not make any connections to the DSP loudspeakers, or to any other component in your system, while the AC power supply is connected and switched on.
DSP5200 and DSP5200HC To fit the rubber bumpons (DSP5200HC only) • Attach four bumpons to the underside of the speaker, using the self-adhesive pads. Tightening the drive units The DSP loudspeakers typically take about two weeks of normal use for the drive units to settle. It is therefore recommended that you tighten the mounting bolts on each drive unit every few days during this period. Tighten the bolts in symmetrically opposite pairs using the 3mm hex wrench supplied.

20 Connecting up the DSP loudspeakers Auto configuration Positioning the digital loudspeakers In a system of Meridian products one of the products acts as the controller for the system. It receives infra-red commands from the MSR+ and then, if appropriate, relays them to the other products in the system via the Comms link. For best results adjust the position of the loudspeakers while listening to music.
21 Using the DSP loudspeakers Using the DSP loudspeakers In systems with a Meridian surround controller all of the functions of the DSP loudspeakers, including volume, treble, and bass, are operated via the controller. For more information refer to the user guide for the surround controller, and you can ignore this chapter. The DSP loudspeakers can also be connected directly to up to two digital sources to create a complete, minimum system.
22 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. If you are not going to use the DSP loudspeakers for several days you should switch each unit completely off at the back panel, and disconnect it from the AC power supply.
23 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.
24 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. When you first connect power to the DSP 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.
25 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. 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.
26 Using the DSP loudspeakers Changing the listening position The balance control of the DSP loudspeakers uses digital signal processing to compensate for an offcentre 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 DSP loudspeakers, like a balance control operating in the vertical plane.
27 Configuring the DSP loudspeakers Configuring the DSP loudspeakers This chapter explains how to configure the DSP loudspeakers to suit the other equipment in your system. The first stage in configuring the DSP loudspeakers is to choose one of the standard settings, and these are designed to set all of the parameters to their most common values. You can also configure each setting individually for applications not catered for by one of the standard settings.
28 Configuring the DSP loudspeakers Choosing standard settings The DSP loudspeakers provide the following five alternative standard settings, called Types, which configure all aspects of the DSP loudspeakers into the most commonly needed configurations: • Release the remote key. The display will show: L.M.RJ45 You should now specify the speaker’s position as follows. Type Description 1 Standard setting for 2-channel system. 5 For use with a Meridian CD player (eg 808.
29 Configuring the DSP loudspeakers Initially all sources will be configured to use the primary input you have specified, but you can configure individual sources to use the other input; see To configure a source, page 31. For example, to define the left speaker as a slave using the digital co-axial connectors: The display shows: L.S.Coax When you have configured the loudspeaker: • Switch off the DSP loudspeaker, using the power switch on the back, and then switch on again to restore normal operation.
30 Configuring the DSP loudspeakers Specifying information about your system You can configure the operation of the DSP loudspeakers to suit the way your system is set up, and the way in which you want to use it. These settings are configured automatically to appropriate values when you choose one of the standard Type settings, and you should not normally need to alter them; see To select a standard setting, page 28.
31 Configuring the DSP loudspeakers Configuring the sources The DSP loudspeakers provide 12 sources corresponding to the 12 source selection keys on the remote: To configure a source CD, RADIO, DVD, AUX, DISC, TAPE, TV, CABLE, SAT, VCR1, VCR2, and GAME. • Press the source key on the remote corresponding to the source you want to configure. If the configuration you want is not catered for by one of the standard settings, you can configure each source individually.
32 Configuring the DSP loudspeakers Configuring the setup options The setup options allow you to adjust the frequency response of the loudspeakers to compensate for their position. You only need to configure the master loudspeaker. When configuring the DSP loudspeakers, point the remote at the speakers, even if you have a Meridian Surround Controller. To select Setup mode • Press Function A or Function V to select the appropriate option as follows: Option Free Flat frequency response.
33 Configuring the DSP loudspeakers To adjust the centre frequency response and tilt offset If your system includes a DSP centre speaker you should set Centre Y on the master speaker. An additional frequency response option is then provided to allow you to adjust the centre speaker, with the options: C.Free, C.Boun., C.Sub 1, C.Sub 2, and C.Corner. • Press Function > or Function < until the display shows the current centre frequency response. For example: C.
