Hello! This is my first post. Sorry for my poor english.
Few days before I bought M&K SB 1250 sub. I connected it to LFE (Onkio 708 reciever) and hi-level (Pioneer A-50 amp which i use for front speakers).
For movies, after the calibration, level on the sub is less than ref level on the sub (less than middle of the scale). The reciever set -3dB for the sub.
The problem is that it is not enouth for hi-level. If I use sub for music (reciever is not in use in this case, only amp) I need to increase the level on the back of the sub, somehow remembering position of the level for movies.
The question is:
Can I set the level I need for hi-level connection and than start new calibration. For example reciever at the beginning (then mic starts measuring) shows sub level 85 dB. Then I'll stop calibration and set not -2dB (as now) but -12db in reciever.
In this case I'll have the same level for both connections of my sub.
But I feel that -2dB and less level on the sub and -12dB with more level on the sub is not the same. May be because of the weaker signal from the reciever I'll get worse sound (loss in little details, more distortion).
But may be it is the simple mathematical task and I shouldn't bother?
