Hi, I am shortly about to recieve a powernode 2021 version and also a REL Tzero subwoofer. The subwoofer has two inputs I am likely to use One RCA input labeled LFE and second RCA input labeled Low Level Input. Question is which one do I use with the bluesound powernode? Thanks

  Hi EarJam

  I would connect the POWERNODE Sub out to the REL TZero .1 / LFE INPUT. Set Phase to 0. Set .1 /LFE LEVEL to 12 o'clock. Then in the BluOS App, under Settings, Audio, enable the SUB and adjust the variable crossover to what you want (The default is 80Hz).

  Then play some moderately heavy bass and adjust the REL .1 /LFE LEVEL to your liking.

  You should use the low level input as per the REL manual:

  4 LOW LEVEL INPUT: Used to connect LOW LEVEL to the output of a preamplifier, integrated amplifier
  or receiver ONLY when HIGH LEVEL INPUT cannot be properly connected. (For home cinema,
  use.1/LFE INPUT).
  5 .1/LFE INPUT: Used to connect to the .1/LFE output from a theatre processor. Should be used in
  conjunction with REL HIGH LEVEL connection for the ultimate theater experience

  That is what I am using with my Node 2i

  You do not have the LFE function in Powernode (unless something has changed in the newest version).

  Thank you both for your input and guidance. After a quick Trial out of both methods I found that the low level input and running the powernode with subwoofer off sounds optimum. I believe the power node is sending a full ramge mono signal out the sub rca. It maybe my current speakers but giving these full range helps integrate the sub better (this might not be the case for all speakers just mine work better this way!) I also found tuning the REL sub quite easy as it has crossover and input gain dials. This way the bass management is being done by the sub. Not all subs will have this management. Anyway cheers.
