Rega HAL + EXON manual?

hmm . . . I'm not familiar with how the Exon amps connect to the Hal. Doesn't the Exon have an XLR input?

I drove a standard unbalanced amp with my Hal by using a standard XLR cable, with a pig-tail that I made to attach to it splitting it into 2 RCA outputs R and L.

Solved it! If you want to use a standard XLR cables you can do that. The only thing you have to do is opening one of the XLR plugs - only on one cable, and switch the cores between pin 2 and pin 3.

If you want to make you own cables, you only need a standard RCA cable with 2 cores and 4 standard XLR plugs (2 male, and 2 female).

At the HAL end you connect the cores to pin 1 (gnd.) and 2 (right) at one cable, and pin 1 (gnd.) and 3 (left) on what becomes the left cable. At the EXON end of the cables you connect the cores to pin 1 and 2 on BOTH cables! as the EXONS only used pin 1 and 2...

Why REGA chose to take perfectly standardized XLR cables and twist them that way, instead of using standard RCA plugs and cables I don't know. Perhaps they saw this as an opportunity to sell their own "proprietary" cables? ;-)

The only benefit I see, is that you can Quad-amp and connect a subwoofer to the HAL, because it actually has both right and left channel in both outputs.

their explanation to me was that XLR connectors offer superior contact vs RCA. If not connecting to mono-blocks it had another advantage of only needing one XLR cable, since the connector on the Hal side has both R and L signals present, assuming this was also the case on the amp side. I suspect they realized they out-finessed themselves on this idea shortly after introducing it, as they never did it again as far as I know . . .

glad to hear you got it solved. I imagine the combination sounds really nice.
