1- So I measured the spl of the fan at idle with no other devices in the rack turned on and it's 60db at about a foot from the front of the faceplate. I've got a 24" box fan that isn't this loud, and the amp isn't even amplifying anything. Is this the way they all are? I'm not even aware of any 12v fans that are in the neighborhood of 60db. The fan in my rack is 12db.
2 - I didn't measure right at the faceplate because the amp blows air out the front of the faceplate. Every other piece of equipment I've had pulls air in from the front and blows it out the back. So now this amp is exhausting into the intake of all the other equipment. Seems bass ackwards to me.
3 - Gain structure doesn't seem to work well. I have to dime the gain to get decent output comparable to the 300w plate amp it is supposed to be replacing. I may be able to adjust the LFE out level on the AVR to make this work though.
What are your experiences? Is there a decent fan mod? If not then I don't think this amp will work for me.
