I have the CVP 809, and referring to the page which has speaker connectivity. The Binaural is set to “off” . Is this the correct setting, I don’t use headphones, and can’t quite understand whether it should be set on or off, reading the manual and reference manual, I am a little confused re this. The IAC is set on, depth set on 2. Would appreciate any help, in easy to follow, for an “oldie”. Many thanks.
