NuForce DAC-80 Digital to Analog Converter
Connections
Connect the appropriate digital source to any of the available digital inputs by using a high quality corresponding
cable type (USB, coaxial or Toslink).
The analog RCA output should be connected to your preamp using high quality interconnect cables. Please note:
It is not recommended to directly drive a power amplifier from the RCA outputs.
Inputs
The DAC-80 provides for connecting up to four digital sources. They are selected in the following order:
• Input #1 - USB
• Input #2 - SP/DIF coaxial/RCA
• Input #3 – SP/DIF optical/Toslink
• Input #4 – SP/DIF coaxial/RCA
To select the desired input, simply press the Input buttons labeled 1 – 4. Once pressed, the selector button will
illuminate. Please note: the last-selected input is memorized when DAC-80 is turned off and will become the active
Input when the unit is turned back ON.
Volume Control
The volume knob is a one-turn control. Pressing in on the knob turns the DAC-80 ON and OFF (OFF = standby).
The volume at turn-on will be determined by the knob position.
LED Indicators
A stable and fully illuminated LED indicates the sample rate.
• Blue = multiples of 48kHz
• White = multiples of 44.1kHz
A blinking LED indicates that the output is muted.
When the six LEDs light sequentially in a clockwise pattern, the digital signal is not standard PCM format. Rather,
while the DAC-80 has locked onto the signal, it may be a DTS signal (such as from a Blu-ray player) or some format
using a non-standard sample rate (such as 38.8kHz).
No LED indicates that the unit is OFF or in standby mode.
Using the Remote Control
The DAC-80 comes with a simple remote control with the following buttons:
• On
• Off
• Input – cycles through Input 1 to 4
• Volume +
• Volume -
• Mute
When using the Remote Control to change the volume, please note: the knob on the front panel is not motorized
and therefore will not turn. However, moving the front panel knob will immediately change the volume to that
knob position.
