Why no 2nd XLR out on SCA2

[fattymatty]

Hi. I'm wondering why ATC doesn't include 2 sets of XLR out on the SCA2 flagship preamplifier. I have ATC 100 Active towers and the SCA2 and want to add a C4 or C6 sub but those subwoofers only accept an XLR interconnect. The signal strength from the preamplifier from RCA is often lower than XLR making it difficult to match an ATC sub with large actives. I tried C1 sub and simply couldn't get the sub to be audible at my normal ATC 100 listening levels even when the sub gain was at its 99 max level. C4 and C6 should be louder and this might not be problematic, but... it's an expensive experiment if I buy a larger C4 or C6 sub and have this same issue.
