ENGLISH Using as a D/A converter Connect and playback from a devices with digital audio connectors (Coaxial/Optical) 1 Connect devices with digital audio connectors to this unit (vpage 9). 2 Press DISC/INPUT to change the input source to "Coaxial" or "Optical" (vpage 13). The input digital audio signal is displayed as shown. "Coax: zzzzzk" or "Opt : zzzzzk" (zzzz indicates the sampling frequency. ) • If the sampling frequency cannot be detected, "Unlock" will be displayed. nnFiles that can be played back • See "D/A converter" (vpage 31). NOTE • Do not input non-PCM signals, such as Dolby Digital, and DTS.

Switching the filter characteristics 2 filter characteristic types can be selected for Super Audio CD playback, and for audio CD playback. The 2 filter characteristics types are explained below. Filter Type FIL 1 FIL 2 Audio CD Super Audio CD Offers a short impulse Precisely reproduces response for both pre-echo high resolution and post-echo. Suitable audio that has large for large-information- information content. content audio. Produces a deep sound image with clearly-defined positional relationships of the audio sources. This is a long coefficient FIR filter with symmetric pre-echo and post-echo in the impulse response. Resembles analog sound quality. Attenuates portions that exceed 100 kHz. Characterized by a well-balanced, smooth sound. Press FILTER. • The setting cycles through the 2 modes (FIL1 / FIL 2) and off as shown below each time the button is pressed. FIL1 FIL 2 NOTE The filter characteristics have a last memory function. These settings remain in memory even if a disc change occurs, or if the power is turned off. 23
