Connecting Your D/AC-1100 HD
When you make connections, be careful to avoid tension on digital and audio interconnects which might
cause damage to the connectors or cause them to pull loose. Do not attempt to 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-1100 HD has four digital inputs: 2- 75
Coaxial, TOSlink, and AES/EBU. It is possible to
connect four separate digital sources to your D/AC-1100 HD and select among them from the front
panel. However, radiation from the 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(s) until you are ready to listen to it.
Coaxial: RCA jack - 75
standard
75
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. Cables designed for audio
frequencies are not suitable and will not give you satisfactory results.
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 to select an
appropriate optical cable with TOSlink connectors.
AES/EBU: Balanced XLR Connection
AES/EBU (Audio Engineering Society/European Broadcast Union) balanced connections have become
the standard digital connection for professional digital audio equipment. Balanced AES/EBU XLR
connectors are also 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. Cables designed for audio frequencies are not suitable and will not
give you satisfactory results.
Analog Output Connections
Analog output jacks connect to any line level input on your preamplifier or even directly to your power
amplifier provided it is equipped with level controls. Use only high-quality interconnects to preserve
detail and clarity. Make sure your preamplifier is either turned off or its volume is set to minimum
whenever making connections. There are two analog output connections: Unbalanced RCA jacks for
unbalanced line output and balanced XLR connectors for balanced line output- Pin 1: Ground, Pin 2: +
signal, Pin 3: — signal
Digital Output Connection
The digital output jack passes your digital source's data stream directly to a digital recorder like a Mini
Disc, DAT, DCC or CD-R. Use only digital quality cable for this RCA connection.
AC Power Cord
Your D/AC-1100 HD has an IEC standard detachable power cord that has been specially selected for its
contribution to the sound quality of this unit. Try to connect only this cord directly to a nearby AC wall
outlet and avoid extension cords or connection to accessory outlets on your preamp.
