Explanation of termsSampling frequencySampling involves taking a reading of a sound wave (analog signal) atregular intervals and expressing the height of the wave at each reading indigitized format (producing a digital signal).The number of readings taken in one second is called the “samplingfrequency”. The larger the value, the closer the reproduced sound is to theoriginal.Linear PCMThis is an uncompressed PCM (Pulse Code Modulation) signal. This is thesame system used for CD audio but uses 192 kHz, 96 kHz, and 48 kHzsampling frequencies on Blu-ray Disc or DVD and provides higherresolution than CD.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).PairingPairing (registration) is an operation that is required in order to connect aBluetooth device to this unit using Bluetooth. When paired, the devicesauthenticate each other and can connect without mistaken connectionsoccurring.When using Bluetooth connection for the first time, you need to pair thisunit and the Bluetooth device to be connected.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.Contents Connections Playback Settings Tips Appendix44Front panel Rear panel Remote controlunit Index
