I have a home theater system in which I have a Denon AVR-590 receiver. I never did receive a set-up microphone to
perform the Audyssey Auto Setup procedure. I think I would get some better sound quality out of my movie watching experience and so forth.
Is there any other way to calibrate this system without the microphone? Where can I purchase a microphone for this calibrating procedure?
You can repurchase the mic from one of Denon's parts distributors. All you need is the receiver model number. The microphones are different per receiver, so a generic, or the mic from a different product won't give you the best results.
