"When using the multi-channel analog outputs the Subwoofer output is -10dB lower than the other channels. If your receiver does not perform a +10dB subwoofer boost, then you will need to manually set Subwoofer to +10dB."
Neuromancer: "Additional: Subwoofer will be -10dB off the bat, and another -5dB (total of -15dB) when the player is performing the bass management over multi-channel analog."
I missed this despite following a lot of the posts in this forum. I have small speakers, and send 5.1 analog audio to my receiver (Panasonic SA-XR57). I just re-read the receiver's user manual, and it indicates that the subwoofer default setting is 10, with a range of 1 to 19 (versus -10 to +10 on the other channels with a default of 0), so I presume that the receiver "performs a +10 dB subwoofer boost". What is with the extra +5 dB that Neuromancer is referring to?
