    Ok. The 940 should output a 'white noise' test tone from each speaker individually. Left front, centre, right front, right rear left rear and left front again. You take note of the the read out on the DB meter for the left front speaker. Then for each speaker, check the level and adjust volume until all have the same DB level on the meter. I did this for my speakers but found that I actually liked to turn up the rears a bit to make the surround effects a little bit more prominent.

    One thing I forgot to add is what level of volume should I set the Amp to when listening to the test tone ?

    Hi,
    Set the meter to around 70db 'C' wieghting, site the meter the best you can in your normal listening posistion and calibrate your test tones to read the same from all five speakers and your sub. As someone mentioned, you may like to increase your rears or you may not. Its personal preference!
