-3- Connecting Your D/AC-2000 When you make connections, be careful to avoid tension on digital and audio interconnects that might cause damage to the connectors or cause them to pull loose. Do not bend either coaxial or optical digital cables at an angle, this could permanently damage them. Be sure to turn off the power of your preamplifier and power amplifier while making connections. As an additional safeguard, turn your preamplifiers volume control to minimum. Digital Inputs Your D/AC-2000 has four digital inputs: Coaxial, AES/EBU, ST Optical, and TOSlink. It is possible to connect four separate digital sources to your D/AC-2000 and select among them from the front panel. However, radiation from unused digital inputs may contaminate the sound of the selected input source. If you have more than one digital source connected, make sure you turn off the power of the unused source until you are ready to listen to it. Coaxial: RCA Connector - 75 W W W W W Unbalanced 75 W coaxial output connections are provided on many high quality CD players. You should use only good quality cables which have been designed for digital data transmission such as the Stereophile recommended Parasound DataBridge. Cables designed for audio frequencies are not suitable for digital signals and will not give you satisfactory results. AES/EBU: XLR Connector - 110 W W W W W Balanced AES/EBU (Audio Engineering Society/European Broadcast Union) 110 W balanced connections have become the standard digital connection for professional digital audio equipment and are becoming increasingly popular with high-end consumer equipment. AES/EBU connections are thought to be superior to coaxial, TOSlink, and even ST connections because of their inherent noise rejection capability. When you use the AES/EBU connection, be sure to use one designed for digital transmission such as the recommended Parasound Balanced DataBridge. Cables designed for audio frequencies are not suitable and will not give you satisfactory results. Optical: ST Fiber Optic The ST module employs the AT&T data transmission standard. ST fiber optic connections are considered by some to be superior to either TOSlink or coaxial connection for data transmission. Use care when connecting the ST connector to the D/AC-2000. ST connectors are more fragile than other connectors. Pay special attention to the guide pins when making an ST connection; never try to force the connector. Optical: TOSlink Fiber Optic TOSlink fiber optic connections are also popular and are found on most high-quality video laser disc players as well as older CD players and CD transports. Your dealer can assist you in selecting an appropriate optical cable with TOSlink connectors.
