Speaker impedanceThis is an AC resistance value, indicated in Ω (ohms).Greater power can be obtained when this value is smaller.Source directPlayback with higher fidelity to the source becomes possible, as inputaudio signals are output by bypassing the audio quality-control circuits(BASS/TREBLE/BALANCE).Protection circuitThis is a function to prevent damage to devices within the power supplywhen an abnormality such as an overload, excess voltage occurs or overtemperature for any reason.Trademark information .Adobe, the Adobe logo and Reader are either registered trademarks ortrademarks of Adobe Systems Incorporated in the United States and/orother countries.Contents Connections Playback Settings Tips Appendix41Front panel Rear panel Remote controlunit Index
