i.LINK® Digital Audio Interface From the initial launch of Super Audio Compact Disc, the 1-bit Direct Stream Digital™ pulse train was always converted to analog prior to output from the player. While SA-CD players have included coaxial and optical digital outputs, these outputs handled CD signals exclusively. The SCD-XA9000ES was Sony's first SA-CD player to provide an i.LINK digital output for the 1-bit DSD signal. And the STR-DA9000ES was Sony's first receiver to incorporate an i.LINK digital input. The DA71000ES carries this ability forward, maintaining the signal in the digital domain and simplifying the signal path. The i.LINK interface also enables a single digital cable to take the place of six analog cables. SA-CD Player Amplifier Speakers SA-CD D/A convert A/D DSP convert D/A LPF convert Volume Analog Power Amp DVP-NS9100ES STR-DA7100ES Speakers SA-CD DSP S-Master Power Amplifier LPF Digital Signal Analog Signal Typical SA-CD reproduction involves numerous D/A and A/D conversions. Connected to a compatible SA-CD player, the STRDA7100ES maintains the signal in digital form. The i.LINK digital audio interface uses Digital Transmission Content Protection (DTCP), a robust system that protects the music from piracy. The application of the i.LINK (IEEE 1394) interface to digital audio is clearly different from-and not compatible with-previous i.LINK interface applications for DV camcorders, PC peripherals and professional digital video systems. You can only connect the STR-DA7100ES i.LINK interface to a compatible digital audio output, such as that on the SCD-XA9000ES SA-CD/CD player and the DVPNS9100ES DVD/SA-CD/CD player.
