Connecting Your D/AC-1600 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
preamplifierÕs volume control to minimum.
Digital Inputs
Your D/AC-1600 HD has four digital inputs: 75
W Coaxial, TOSlink, AES/EBU, and ST Optical. It is
possible to connect four separate digital sources to your D/AC-1600 HD and select among them from
the front panel. However, radiation from the unused digital inputs may ÒcontaminateÓ 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
W standard
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. 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.
Optical: ST Fiber Optic
ST module glass fiber optics are considered state-of-the-art in fiber optic transmission. They are
superior to TOSlink connectors for data transmission. The ST module employs the AT&T standard;
both plastic and glass fiber optic connectors are available for ST modules 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: Ñ signal
Digital Output Connection
The digital output jack passes your digital sourceÕs 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-1600HD 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.
Operating Your D/AC-1600 HD
Power Switch
Push the upper section of the button to turn on; lower section for off.
Input Select Buttons and LEDs
The four input select buttons correspond to the four input connectors on the rear panel: Coaxial, ST,
TOSlink, and AES/EBU. Press any of these buttons to select the desired digital source. An LED will
illuminate to indicate which digital source is selected.
Polarity Invert Button and LED
This button allows you to select between 0° normal operation and 180° inverted polarity. Even if you
know if your preamplifier and power amplifier are inverting or non-inverting designs, you have no way
to know which of your CDÕs may have been recorded with inverted absolute polarity. Absolute polarity
means the + and Ñ of both channels are reproduced so the compression wave of an initial musical
attack correlates to the compression wave (+) from outgoing speaker diaphragm motion rather than
rarefaction (Ñ) of in-going speaker diaphragm motion. Your choice of 0° or 180° polarity will be
strictly a matter of taste. It may be easier to detect differences between 0° and 180° polarity with some
recordings than with others. DonÕt be discouraged if you cannot bear the difference; not everyone can
identify absolute polarity.
HDCD
ñ LED
If you play a CD that has been encoded with the HDCD
ñ process, this LED will illuminate. This LED
will remain off on standard recordings.
Sampling Frequency LEDs
Your D/AC-1600HD will recognize the digital signal of whatever type of digital source you connect and
will switch to the correct sampling rate automatically. The 44.1 Hz sampling rate is standard for
compact discs. 32 Hz is for digital broadcast; 48 Hz is for DAT.
De-Emphasis LED
Some digital recordings are encoded with pre-emphasis contouring. Your D/AC-1600 HD automatically
recognizes and processes them. An LED will indicate that the recording is being de-emphasized.
ÒBurning-InÓ Your D/AC-1600HD
Like most other great audio components, your D/AC-1600 HD needs to operate for at least 72 hours
before it will start sounding its best. This allows the materials of various internal parts to ÒformÓ so they
can better process the complexities of musical waveforms. While your unit will sound spectacular right
out of the carton, you will find it worthwhile to listen again after a few days. You will discover details
in your music you may not have guessed were there.
