The two sockets are not hardware-set as either D1 or D2. Instead, the input numbering is determined by a setting chosen when the loudspeaker has its “Type” set. If “RJ45” was selected when the loudspeaker 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 loudspeaker acting as the Master loudspeaker 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 loudspeakers to be fed with two different sources of audio without additional switching hardware. Naturally, this allows the loudspeakers to be used as a simple, self-contained system with two sources, but it also allows for a pair of loudspeakers 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 loudspeakers.
The tweeter and mid-range drivers on the head unit take care of treble and mid-range with each unit being fed from their own dedicated amplifier. The bass drives are wired in pairs with each pair fed by their own amplifier. The uppermost two pairs of bass drives receive the whole range of bass frequencies. However, the lowest pair is fed with only the very lowest bass frequencies in order to give the loudspeaker its tremendous bass extension and power.
Yes. By default, the loudspeakers have EBA enabled and the internal switch for EBA is set to change only if a loudspeaker receives the relevant command on its Speakerlink input. This is determined by the setting “EBA SL” in the configuration of the loudspeaker. 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 loudspeakers display. One option has the display light up briefly when the loudspeaker 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.
If a Meridian product is feeding the loudspeakers from a single Speakerlink output then the loudspeaker directly connected to the source product must be set as Master. For convenience of wiring, this usually leads to the loudspeaker which is nearest to the source product being set to Master. However, it is perfectly okay to set the more-distant loudspeaker as Master as long as the cabling is arranged accordingly. IR control is possible only on the Master loudspeaker, not the Slave. So, if IR control is a requirement and one of the loudspeakers is better positioned than the other in regard to “line-of-sight” for reception of IR from the user’s remote control, then this loudspeaker may need to be made Master regardless of which is nearest to the source product.
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 loudspeaker has a sampling rate of 88.2 kHz or higher.
These signals are upsampled to 88.2 kHz and 96 kHz respectively within the loudspeaker.
This shows that the loudspeaker has activated its first level of thermal protection. When the loudspeaker’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 loudspeaker will sound tonally unbalanced in this state.
