The signal I get on certain close-miced drums is too hot for my mixer, which
doesn't have any built-in attenuation. Do I need to buy an attenuator from a
supplier or can I just build my own with resistors? If I need 10-20dB of
attenuation, what values should I use, and what about impedance issues? Is
there any significant difference in sound quality between using different
components (resistors, wires, solder etc), or just a difference in accuracy
of level reduction?

Thanks,
