How to set up Meridian "Display-type" DSP loudspeakers


The two sockets are not hardware-set as either D1 or D2. Instead, the input numbering is determined by a setting chosen when the speaker has its “Type” set. If “RJ45” was selected when the speaker was Typed, then the Speakerlink input becomes “D1”. If “co-ax” was selected during Typing, then the RCA (coaxial) digital input will be assigned as “D1”.

The speaker acting as the Master speaker in the system can be configured to switch between its input sockets according to which source is selected on the system. This feature allows a pair of speakers to be fed with two different sources of audio without additional switching hardware. Naturally, this allows the speakers to be used as a simple, self-contained system with two sources, but it also allows for a pair of speakers which are connected to an audio matrix or other multiroom equipment to be switched between the external feed and a source local to the room containing the speakers. 

The DSP7200 is a four-driver, three-way design. Each of the drive units is fed from its own dedicated amplifier. Within the speaker, audio is split into three channels; treble, mid-range and bass. The treble and mid-range signals are fed into individual amplifiers for the tweeter and mid-range. The single bass signal is split and fed into the two amplifiers powering the bass-drives.

Yes. By default, the speakers have EBA enabled and the internal switch for EBA is set to change only if a speaker receives the relevant command on its Speakerlink input. This is determined by the setting “EBA SL” in the configuration of the speaker. Having the setting on “SL” means “do as instructed over the Speakerlink connection.”  This setting can be changed to “ON” or “OFF” which switches EBA to be enabled or disabled irrespective of any command received over Speakerlink.

Yes. There are options for what the speakers display. One option has the display light up briefly when the speaker controls are used, but blanked in between times. For example, the display will appear to show the volume being turned up or down, but will revert to blank after a second or two.

Either speaker can be set as Master – it just needs to be connected to the “Master” socket on the product feeding the speakers. The one consideration to be taken into account is that only a Master speaker can be configured to accept IR commands. If IR control through the speakers is a requirement, it may be that the physical location of the speakers may mean that one is better positioned than the other in regard to “line-of-sight” for reception of IR from the user’s remote control.

If a Meridian product is feeding the speakers from a single Speakerlink output then the speaker directly connected to the source product must be set as Master. For convenience of wiring, this usually leads to the speaker which is nearest to the source product being set to Master. However, it is perfectly okay to set the more-distant speaker as Master as long as the cabling is arranged accordingly. IR control is possible only on the Master speaker, not the Slave. So, if IR control is a requirement and one of the speakers is better positioned than the other in regard to “line-of-sight” for reception of IR from the user’s remote control, then this speaker may need to be made Master regardless of which is nearest to the source product.

In a Meridian system, digital audio is distributed in pairs of channels. This seems obvious when a pair of speakers is “daisy-chained” However, it is also true when a system is “star-wired”; each Speakerlink lead always has the ability to carry two channels of audio. Therefore, each speaker must be configured to pick up and play back the correct channel from the lead. Even in cases when there is no sound present in a channel, such as when there is no subwoofer defined in a surround system, the lead connected to the centre-channel still carries digital silence in the unused channel. Set the speaker to pick up the wrong channel and it will play back this silence.

No. Meridian DSP loudspeakers feature internal protection which, when activated, can demand high current from the mains supply in order to blow the fuse within the product. This is a deliberate aspect of their design and is a key safety feature. If, under these conditions, anything inhibits the current required to blow the fuse, the loudspeaker will be exposed to circumstances for which it was not designed. Such circumstances could result in catastrophic damage. It may be thought that this can be avoided by using a mains conditioner which boasts a current rating which is higher than that required to blow the loudspeaker’s fuse. However, the possibility of the mains conditioner itself developing a problem needs to be considered.  If a problem in the conditioner restricts its current delivery capabilities, and then the loudspeaker suffers a failure as described above the fuse may not blow resulting in catastrophic damage.

This is the “High Speed” indicator. It shows that the digital signal received by the speaker has a sampling rate of 88.2 kHz or higher.

These signals are upsampled to 88.2 kHz and 96 kHz respectively within the speaker.

This shows that the speaker has activated its first level of thermal protection.  When the speaker’s internal thermal model suggests that the mid-range or tweeter is too hot, the DSP section will turn down its gain slightly and the green LED comes on. Since the bass isn’t turned down the speaker will sound tonally unbalanced in this state.

This shows that the speaker is taking extreme measures to protect itself from being overdriven. At volume levels over 95, if the first level of thermal protection is not enough to protect the speaker, the speaker will force its volume level to 95 and display “Pro95” until it establishes that it has cooled sufficiently to go back into normal mode.

Yes. Audio fed into the coaxial input is fed through to the coaxial output and Speakerlink output simultaneously.

Yes. Audio is sent out of the coaxial and Speakerlink outputs simultaneously, regardless of which input socket is used.

Yes. The speaker sends out comms from the BNC and Speakerlink outputs simultaneously regardless of which input socket is used.

Yes. The speaker sends out comms from the BNC and Speakerlink outputs simultaneously regardless of which input socket is used.
