DSP5000 description

You will find it simpler to understand how the DSP5000 works if you consider it as a combination of the following components:

∙digital preamplifier, to select and control up to two digital sources directly, and to provide fixed and switched digital output for the other DSP5000

∙digital audio processor, whose functions include decoding as well as error detection and correction

∙digital signal-processor, dealing with tone controls, digital crossover, dynamic bass control, balance and volume

∙two precision digital to analogue ΔΣ converters for bass-mid and tweeter

∙remote control for all functions, including volume, balance, mute and various tone controls

∙controlling computer

∙RS232 control and display capability

∙Meridian 500-Series communicator

∙Meridian 200- or 600-Series communicator

∙2½-way active loudspeaker, with three drive units and three 75W power amplifiers per speaker

Master and slave speakers

In every room containing DSP5000s, one speaker is chosen (by means of either factory setting or user setup) to be in charge of the other Meridian components in that room. We refer to this as the master speaker. It controls the functions of the other DSP5000, and communicates with all the other Meridian products in the system via the M5-lead provided. The master speaker is also the one that ‘watches’ the remote control, and should therefore be placed so that it has the best possible view of the room, although the connections between the other components of your system must also be considered.

An installation may use 1, 2, 3 or 5 1 DSP5000s: one will always be the master speaker and the others used as slaves.

The master is identified by a red light in the display window.

Centre, left, right and surround

Since the digital audio signal is in stereo format, the DSP5000 needs to be told if it is a centre, or on the left or right. We refer to the DSP5000 which is on the left when viewed from the listening position as the left speaker.

If you have more than one Meridian Digital Speaker, the master can be any of the positions. The choices master/slave and position can be made independently – since selecting which is to be master affects the way the cables run in your installation. As supplied, the DSP5000 is set up as a left master, but you can alter this if necessary using a Type setting (see page 33) or in Config (see page 34).

DSP5000s can be used as surround speakers. In this case they are set to be surround left or right.
