    I have a Yamaha 995 receiver and it doesnt display the db level like other receivers. So basically using my Radio Shack SPL Meter I would use the volume control on my receiver until I get a 0 reading(12o'clock)on my meter at the setting of 75db for my main speakers first. Then I would adjust the other speakers to get a 0 reading and then adjust the sub a little higher than the others. I am using the Avia test disk to do this. I am doing this correctly?

    Yes, it sounds correct.
    Note that the numbers on the flange behind the Volume Control represents dB, so the 12 o'clock position is -16 dB. When you REF Calibrate, just note the Volume Control Knob location.
    In my case, my Yamaha RX-V995 REF Level Volume Knob location = -12 dB (or 1 o'clock position). See my complete REF Level settings using Video Essentials (I have AVIA but use VE for speed and LFE REF Calibration) @ my webpage http://www.geocities.com/p_iturra/VE_995.html

    On the analog Radio Shack meter it has the db's set in increments of 10. So if i set it to 70, what range and im getting? Would the 0(12 o'clock) position be at 70 db's or 75 db's? This is the part I am confused about

    When one sets the RS SPL meter to 70, the O at 12o'clock mean 70dB while 75dB is 5 "clicks" or scale marks to the right.

    Dial = 70
    Speed = SLOW
    Weight = C
    ====
    DIAL Readings
    0 (or 12 o'clock high) = 70 dB
    +6 (positive side of "0") = 76 dB
    . . . so the 'tick' mark between +4 and +6 = 75 dB
    NOTE:
    1) AVIA recommends using 85 dB (-20 dB below Digital 0)
    2) Video Essentials recommends using 75 dB (-30 dB below Digital 0)
    3) Yamaha internal test = VE / 75 dB REF Level

    The Radio Shack meter to me is worth its weight in gold.
    As much as I like and use the Avia, for me setting channels levels with it is problematic. Since it doesn't have a LFE track like the VE disc it counts on my receiver to redirect the one or all of DD 5 channels to the sub for bass. Unfortunately I have the Denon set to LFE only for the sub and this doesn't work at all well. So I use the VE for channel level setting.
