The DAC300 converter has been implemented to give 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.
- 8 mm brushed aluminium front.
- 3 independent very low noise linear transformers (including 2 reserved for the audio line).
- SABRE ES9038PRO Converter (32 bits/768 kHz):
– Dynamic: 137 dB.
– THD+n: -122 dB.
– Signal/Noise ratio: 132 dB. - SABRE ES9311EQ power supply with very low noise (<1 μVrms).
- Separate digital and stage line power supplies.
- Ultra-high precision low jitter clock.
- Asynchronous USB-B input can convert PCM up to 768 kHz and DSD64, 128, 256 and 512 (XMOS USB interface with a specific program designed for ATOLL).
- Volume management by disengageable converter (BY-PASS ON or OFF).
- Unbalanced and balanced output lines.
- 12 independent voltage regulations.
- Symmetrical power supply of the audio output stages (low noise transformers).
- ESA series CLARITY CAP audio MKP link capacitors.
- High-frequency capacitors with silver mica technology.
- Output stages with discrete components, without feedback, polarized in class A.
- Specific transformer for digital stages.
- Standard ATOLL global remote control.
Type of files read:

DAC300 DOCUMENTS
Interface:
- Standard global remote control
- 2 encoders, one for source selection and another for volume attenuation and converter filter management.
- Low consumption OLED display: the display of the source as well as the sampling frequency of the song being played.
“What the DAC300 lets guess, it offers without detour, by the subtle and successful balance between the never aggressive sense of detail, an omnipresent, almost analog tonal richness and a dynamic alacrity always on the alert without overdoing it, leaving the quality sources to express themselves. It is ultimately 100% at the service of musical realism in its proper dimension. Atoll displays its stature here, where the DAC is the heart of a digital system which can be completed with a network player from the brand and/or a good CD drive. Atoll stays in the big leagues with its DAC300.”
