because the lowest actual impedance of
the speakers (as opposed to the speak-

auto setup (too much ambient noise;
obstacles blocking the speakers from
the microphone; the monitor noise is
interfering with the setup; etc.).
• Make sure the room environment is in
line with the guidelines for auto setup
in this manual (see page 13 and Memo
on page 15).
