9. SHOULD I USE MAINS CONDITIONING EQUIPMENT WITH THE LOUDSPEAKERS?

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 and become a fire-risk. 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 and a serious risk of fire will result.
