Subwoofer with XP-22 in unity gain


Given the Pass Labs XP-22 is set for Unity Gain on input 1, can I connect my sub to an RCA output and be able to feed the subwoofer?

Notes:

  1. I am not using volume control on the MSB DAC
  2. I currently have the sub plugged into the AVR
  3. I know there is no real point to the XP-22 in the diagram - still want to know if this will work tho

@testpilot bruh, the last sentence of the first paragraph on page 6 of my manual says: 

You may also set any input to unity (0 dB) by selecting low gain and setting the volume at step 89.

 

The danger in that is you switch inputs to another line level source and your volume stays at 89. 

@goleksiak, the 89db setting is just telling the user where on the volume scale is 0db, i.e. no gain or attenuation.  Also, if you set input 1 at 89, all other inputs by default will be set at 89. This could be a recipe for disaster.  Why not use the Home Theatre pass thru on input 5??

@audphile1 if system volume is set to 89 (0db gain) then what is the harm in switching to another line level input (say a phono)?
