Hi just got good calibrated B and K 2232 sound level meter. Want use it for REW spl meter calibration. Am l in the right direction. Regarss Mfinzi

Thanks, great regards

Greetings, l need clarification, most frequency response measurements are set at db/2.83v/ m. Assuming l have gone through all REW SETUP PRELIMINARIES and my measurement mic and speaker are 1m apart, would l be correct to state that my response would be at 2.83v/m regardless of the power of the...

Hi again. After some research, suggestions have .ade to add high impendance unit gain opamps after the resistor voltage divider input to the sound card. The assumption is that this would take care of the input channel offsets during speaker measureme ts. What the the general opinions here...

Greetings, is it possible to use the line output of a pci sound card to directly drive a speaker through a reference resistor with out a power amp in impedance measurememts. If so , what would an appropriate value for the reference resistor. Mfinzi

Thanks, great regards

Greetings, l just got to setup my REW measurement jig consisting of resistive voltage divider and back to back 3v9 zener diodes. Adjusted the levels using rew to control the levels using a left channel loopback, then connected my jig through a 4 watts amp. When l attempt to calibrate the...

Thanks great regards
