What receiver are you using?

If it has a pink noise generator, you turn on the pink noise and adjust each speaker level to read the same on the meter. Ideally the meter is on a tripod and positioned in your favorite seating postion about ear high. I usually stick the meter into the cushions of the couch, as I do not have a tripod.

The meter should be set to 'C' weighting and slow speed.
