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 preamplifier's
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 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
Balanced
AES/EBU (Audio Engineering Society/European Broadcast Union) 110
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.
