1. Digital Output The Wadia 301 CD is equipped with one digital output to allow the internal CD transport to feed another component such as a digital recording device The digital output is a S PDIF signal on a high quality BNC jack Choosing a Digital Cable For maximum performance we recommend using an ST glass optical cable which can be purchased from your Wadia dealer for any digital audio connections Wadia Digital was the first company to use glass fiber optic data transmission in digital audio and we believe that it offers the best performance of all the available options Based on our experience here is a list of digital interface methods in descending order of performance 1 ST type Glass optical as implemented by Wadia with high quality glass optical cable 2 AES EBU using XLR connector 3 Coaxial S PDIF cable using BNC connector 4 Coaxial S PDIF cable using RCA connector 5 TOSLINK plastic optical cable The quality of any of these transmission methods depends on the quality of the cable and the sophistication of the transmitter and receiver For example a high quality coaxial S PDIF cable can outperform a low quality AES EBU cable A high quality AES EBU cable may outperform a poorly implemented glass optical system If you are using a coaxial S PDIF connection we recommend having the cable terminated with a BNC connector This will provide higher performance than an RCA connector Your Wadia 301 CD input kit com2. optimized for extracting maximum musical information from digital audio data stream e First company to apply glass fiber optics to home audio e Direct Connect system to connect digital audio products directly to amplifier e ClockLink proprietary jitter reduction technology e Swift Current zero feedback current to voltage converter Wadia s digital expertise and record of accomplishment exceed those of any audio company but technology alone does not guarantee musical performance Wadia designs are born of a delicate balance of technology shaped by a passion for music Wadia is proud to introduce the Wadia 301 CD Player a breakthrough in sonic performance and value and a strong evidence of our dedication to music reproduction Wadia 301 CD Design Philosophy The Wadia 301 Compact Disc player is the first of Wadia s new 3 series a range of products that set a new standard for performance aesthetics and value The Wadia 301 CD has received the benefit of over 12 years and thousands of hours of development that have resulted in the Wadia legacy Viewed this way the Wadia 301 CD is one of the most outstanding values in the world of high end music reproduction Wadia Digital Volume Control with Direct Connect The Digital Volume Control and Direct Connect circuitry perform the functions of a preamplifier while the signal is in the digital domain This allows the Wadia 301 CD to be connected directly t
