Problem with older REL subs & class D amps


I'm posting this as a "heads-up" - per tech support at REL - that certain REL sub-woofers of the past do not accommodate tapping into the high level output of class D amps using the cables originally provided.

Options are (a) to use the low level (preamp) output into REL sub low level input, or, (b)obtain a special cable that they call "high level digital out" from a REL dealership.

Subwoofers designed prior to the rise in popularity of class D amps are apparently the ones that fall victim to this. Best to obtain details from a REL dealer or tech support at Sumiko. (It sounds like the folks at Sumiko hope that your dealer can help you with this... understandable, as this is the purpose of a dealer...).

Sigh.

I wish I was able to get more detail on the fix. No one seems to know - except there is a fellow at REL who builds these cables by hand. I'll see if I can get him to let us know. Generally they want to keep things trade secret I'm sure BUT this involves support to existing customers in order to correct a problem. I'd like to think that the issue is simply a matter of filtering but why would they not simply say that if true? We shall see.

Stan, thank you for confirming the issue regarding dealers getting information. I also called a local - long established and very highly regarded - dealer of REL products, only to discover that they had never heard of this problem.

Meanwhile the folks at Sumiko are saying "just ask your dealer"!!!

Sigh.
