Operating Your D/AC-1100 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 CD’s may have been recorded with inverted absolute polarity. Absolute polarity
means the + and — 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 (—) 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. Don’t be discouraged if you cannot hear the difference; not everyone can
identify absolute polarity.

HDCD LED
If you play a CD that has been encoded with the HDCD process, this LED will illuminate. This LED
will remain off on standard recordings.

Sampling Frequency LEDs
Your D/AC-1100HD 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-1100 HD automatically
recognizes and processes them. An LED will indicate that the recording is being de-emphasized.

“Burning-In” Your D/AC-1100 HD
Like most other great audio components, your D/AC-1100 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 “form” 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.

Maintaining Your D/AC-1100 HD
Your D/AC-1100 HD requires no routine maintenance. We recommend that you remove and twist the
various RCA connections once a year to remove any corrosion buildup on plugs and jacks. Make sure
the power is turned off before attempting this. It’s not a bad idea to do this to each of your other
components while you are at it. Never use any abrasive cleaner on the front panel or top cover that may
scratch or disfigure them. Use only a soft cloth moistened with clear water or Windex to remove
fingerprints.
