Hi everyone,

I’m planning to use my WiiM Ultra with an integrated 2-channel amplifier and I also have a subwoofer. I would like to keep volume control and bass management on the WiiM Ultra, not on the amplifier.

My goal is roughly this setup:

WiiM Ultra → RCA out → integrated amplifier → speakers
WiiM Ultra → sub out → subwoofer

So the WiiM would handle:

  • volume control
  • PEQ
  • crossover / bass management for the subwoofer
My question is:
Is this the correct way to connect it when using an integrated amplifier? Should the amplifier volume be set to a fixed position (for example around unity gain / a fixed level), and then control the listening volume only from the WiiM Ultra?

I want to avoid double volume control and make sure the subwoofer integration from the WiiM still works correctly.

Any advice from people running a similar setup would be greatly appreciated.

Thanks!
 
i have only power amps atm but thinking of selling and buy back an integrated amp. I regret selling my mad c399
 
indeed a perlisten r8s sub. I read somewhere that volume control can be a challenge with how you connect it
If you always keep the integrated amp volume at a fixed position and only control the volume on the WiiM Ultra you should avoid any issues.

My goal is roughly this setup:

WiiM Ultra → RCA out → integrated amplifier → speakers
WiiM Ultra → sub out → subwoofer

So the WiiM would handle:

  • volume control
  • PEQ
  • crossover / bass management for the subwoofer
That looks OK to me!
 
How about an integrated amplifier that thinks it is a power amplifier?
