Reference DSD1.1
32Bit/768KHz DSD256 d/a convertor

The Reference DSD1.1 is a high performance D/A convertor for CAS purpose. We use the advanced X-MOS moudule to support DSD playback up to DSD256. The Reference DSD1.1
has a Hi-Speed Audio USB2.0 interface for the digital input from a computer. It supports Native DSD streams mode, this is the pure orignal DSD signal which has never been converted. It also uses
the special USB GND isolation design, which keeps the noise away from the computer's USB. It supports the free Drivers for Apple devices (MAC/ phone/ pad) and Andriod devices.
The clients can use APPs to play DSD and PCM files using an apple or andriod phone and Pad. There is a special tube buffer design before the RCA output, which further improves the sound quality.

The Reference DSD1.1 has an headphone output which adapts to headphones having impedance ranging from 10 to 600 ohm.

Multipile PCM digital filter option
PCM digital filter mode:
1. Short delay Sharp
2. Short delay Slow
3. Sharp Roll-off
4. Slow roll-off
5. Super Slow roll-off

The various digital filter status allows the tailoring of various sounds. The customer can choose a smooth, sharp, fast, slow or the different sound style of their choice.

The DSD supply CUT OFF FILTER gives the option of 50KHz / 150KHz.
It's provides for improving the high frequency sounds, if the recording ultra high frequency has some background noise.

The sound Phase option allows for Phase+ and Phase-.
Some recordings are recorded in reversed phase. The phase ajustment will fix the incorrectly phased recording.

We suggest using the JRiver and Foobar2000 Media Center in the Windows operating system. And we suggest using the "Audir vana plus" Media Center in the iOS system.
