How to hook up a Active Sub to a PA amp (Crown XLS 1002)

Hello -

Here is my system.

  • Amp - Crown XLS 1002
  • DAC - SMSL SU-8
  • PreAmp - JBL Mpatch2
  • Passive Loud Speakers - 2x Polk RTI6
  • Active Sub - Yamaha with RCA out

I
  1. looked online and the only thing I found was that I need to put the loudspeakers in Channel 1 output
  2. And then I need a Y XLR cable from the DAC to Channel 1 of the input (Crown says Channel 2 is turned off in Y mode)
  3. Either a RCA to Speakon cable/adapter to channel 2 for the sub or RCA to banana ect to the channel 2 output.
  4. Then set the lowpass filter on the Crown Amp to direct low frequency on channel 2.
  5. Then I w
ould have to Bi-wire the left and Right polk RTI6 so that they can use one connection.

I guess my other question is imaging, if I bind the loudspeakers to 1 channel how does it tell Left from Right?

If anyone is curious, I think i got it hooked up correctly. And yes you lose imaging. Polk RTI6 has 4 5 way binding posts per speaker so its easy to jump them to each other then to the amp. (like a powered speaker, kinda) Sub adds lots of value, I guess imaging is not that important for just 2 speakers.
Glad you were able to figure it out. I wasn’t able to follow any of that.

What specific Yamaha sub are you (ArgpJunkie Gamer) using?

I hope that it's unnecessary to sacrifice stereo to allow you to connect the sub.
