This is kind of a Back To The Future kind of thing. I have a very old Yammie RX-V3300 receiver that was built long before receivers started coming with built-in self-calibration systems. Up to this point I’ve been crudely calibrating it by ear. It does have a built-in pink-noise generator but it’s basically useless as it jumps from speaker to speaker way too fast to be of any good. I’ve looked for pink-noise discs but I never know how they’re going to work (all speakers playing at once, one at a time, jumping from speaker to speaker, etc) as the descriptions are always so vague. I’m looking for ideas on how I can calibrate this unit more accurately.
