User manual PARASOUND DAC2000

[. . . ] Keep it out of direct sunlight, and away from heat sources such as a hot air vent or radiator. If you are stacking your components, avoid placing your D/AC-2000 on top of heat producing components, such as power amplifiers or tube-type preamplifiers. Keep it as far away from your tuner or receiver as possible to avoid RF interference. -1- D/AC-2000 Front and Rear Panel Drawings D/AC-2000 Ultra Digital/Analog Converter Power Sampling Frequency 32kHz 44. 1kHz 48kHz HDCD Polarity Invert De-Emphasis ST Optical Digital Input Toslink AES/EBU Coaxial De-emphasis Indicator Power Switch Sampling Frequency Indicators HDCD Indicator Polarity Invert Switch Digital Selection Switches Figure #1 D/AC-2000 Front Panel Controls PARASOUND D/AC-2000 Analog Outputs Left Right Coaxial Digital Inputs AES/EBU Toslink ST Optical Ultra Digital to Analog Converter Parasound Products, Inc.

[. . . ] Your dealer can assist you in selecting an appropriate optical cable with TOSlink connectors. -3- 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: RCA jacks for unbalanced line output and XLR connectors for balanced line output. The pin configuration for the XLR connector is: Pin 1 Ground, Pin 2 + signal, and Pin 3 - signal. AC Power Cord Your D/AC-2000 has an IEC standard detachable power cord especially selected for its contribution to the sound quality of this unit. Try to connect 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-2000 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: ST, TOSlink, AES/EBU and Coaxial. Press one 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. Absolute polarity means the compression from an instrument or voice in the original recording corresponds to a compression from the loudspeaker. Conversely, a rarefraction from an instrument or voice in the recording should correspond to a rarefraction from the loudspeaker. 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 and not every recording will reveal it. 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, but the HDCD PMD-100 will continue to operate as a superior digital filter and improve the sound of standard recordings. Sampling Frequency LEDs Your D/AC-2000 will recognize the digital signal of whatever type of digital source you connect and will automatically switch to the correct sampling rate automatically. The 44. 1 kHz sampling rate is standard for compact discs. 32 kHz is for digital broadcast; 48 kHz is for DAT. [. . . ] The Return Authorization number must be clearly marked on the outer carton only. You should ship the unit by UPS with adequate insurance specified. You must include a copy of your purchase receipt to validate your ownership. Units that arrive without your specific Return Authorization number, without a suitable shipping carton or with evidence of improper internal packing will be refused. [. . . ]
