DAC100 Signature

The DAC100 Signature converter has been implemented to offer you the best of your favourite music. Many believe that the secret to a good converter lies in choosing a “high-end” converter chip. If this is important, we know that the essence of the musicality also resides in the line signal processing stages, the power supplies (transformers, filtering, regulation), the digital signal processing before conversion, the quality of the key components: clocks, transistors, capacitors, etc…

  • 4 mm brushed aluminium front.
  • 2 independent transformers (including one reserved for the line audio).
  • D/A converter: BURR-BROWN PCM1796:
               – Dynamic: 123 dB.
               – Distortion rate: 0,0005%.
               – Signal/Noise ratio: 123 dB.
  • Asynchronous USB-B input can convert PCM up to 192 kHz and DSD64 and 128 (XMOS).
  • USB interface with a specific program designed for ATOLL).
  • Volume attenuation by the converter (from the remote control only).
  • Unbalanced line outputs.
  • 7 regulated power supplies.
  • MKP capacitors in audio link.
  • Output stages with discrete components, without feedback, polarized in class A.
  • Separate digital and line stage power supplies.
  • Specific transformer for digital stages.
  • Controllable with the ATOLL global remote control.

The DAC100 Signature can be used with the ATOLL remote control (optional) to:

  • Input selection.
  • Output level attenuation.

In addition, it allows remote control of all ATOLL products (Integrated, Preamps, Tuner, DAC, CD Players…).

The DAC100 Signature is available in black or natural aluminum version:

Black anodized brushed aluminum finish.
Silver anodized brushed aluminum finish.
