Tip
Changing the frequency curve of one channel too
drastically will affect the overall balance. If the
speaker balance seems uneven, you can raise or
lower channel levels using test tones with the TRIM
feature. Use / to select TRIM, then use / to
raise or lower the channel level for the current
speaker.
Looks like it will allow you to change the db level of individual speakers from within Manual MCACC.
This is new to me on the new Pioneer recievers....
Suggestion, I have found what works best for me with the Pioneer MCACC that I run the auto cal, and then copy everything it did to a different memory slot. Then I switch to that memory slot and tweak the settings the way I like them. That is the one thing I like about Pioneer's in room correction over every other companies product.. like audessey's format. Auydessey seems to me to be an all or nothing setup. If you don't like what it did you turn it off and don't use it. YOU CAN NOT TWEAK IT.... why? It makes up its mind that this is how the EQ has to be... you don't like it do it yourself it proclaims... You don't get to use the benefits of the algorithmic processing for the group delay or the standing waves.
Pioneer on the other hand allows you to KEEP the correction response like Standing waves and group delay, and then copy it to a memory slot, saving that info, and if you don't like what it does to the EQ, simply change it to your liking. I pretty much just set my EQ to flat.
