OK, but, what if you have an active sub with built in amp. I have the Rowland Synergy Ili Pre and Rowland 312 Amp feeding Avalon Indra's. If I run XLR cables from Pre to Sub, they will be on a different/separate input. The Synergy lli has 5 separate input switches. Obviously only one input can be selected at one time for playback (Balanced 2 channel - outs). What am I missing here?
Subwoofer connection
I've read quite a few posts on subwoofer connection for 2 channel amp/preamp. Here are different ways of connections from what I have read.
1. Using speaker wires.
a. Serial connection: from amp/preamp to the subwoofer in, and then from the subwoofer out to main speakers.
b. Parallel connection: from amp/preamp to both subwoofer and main speakers.
2. Using RCA cables, from the amp/preamp RCA out (or tape out) to RCA input of the subwoofer. Some people suggest to use just one wire from the left out from the amp/preamp to the left in of the subwoofer. This option is not possible for amps that do not have RCA out.
I have a subwoofer that allows those three different connections. However, I could not conclude which connection would be the best by reading posts. I might need to make my own decision for best result, but I would appreciate it if any of you have some thoughts on this.
