High-Resolution Digital Conversion and Preamplifier Control in a Compact e.One Chassis
The Bel Canto e.One DAC2.8 Control Pre-amp and DAC in Black combines high-resolution digital conversion, precision volume control and flexible source connectivity in Bel Canto's compact e.One platform. Its HDR Core architecture integrates ultra-low-noise master clocks, advanced asynchronous digital interfaces and a dual-differential 24-bit/192kHz DAC section to reduce jitter and preserve musical detail from computers, CD transports, streamers and other digital sources.
The DAC2.8 also functions as a complete control preamplifier, allowing its variable balanced XLR or RCA outputs to connect directly to a compatible power amplifier or active loudspeaker system. AES/EBU, coaxial, optical and asynchronous USB digital inputs are joined by a stereo analog input, while a dedicated high-current headphone amplifier provides up to 300mA of output current for high-quality personal listening.

Dedicated High-Current Headphone Amplifier — Provides up to 4.5Vrms and 300mA from the front-panel headphone connection for serious personal listening.
Technology & Design
HDR Core Architecture — Bel Canto's High Dynamic Resolution platform brings together ultra-low-noise master clocks, asynchronous digital interfaces, low-noise power supplies and precision digital processing in a unified conversion architecture.
0.07-Picosecond Master Clock Noise — Extremely low clock noise helps reduce timing errors and jitter before conversion, contributing to the DAC2.8's high resolution and 124dB dynamic range.
Analog Input with 24/192 ADC — The stereo RCA analog input is converted by a high-resolution 24-bit/192kHz analog-to-digital stage, allowing analog sources to benefit from the DAC2.8's digital volume and control architecture.
Balanced Differential Analog Output — Separate XLR and RCA output stages provide low output impedance and sufficient voltage to directly drive compatible power amplifiers and active loudspeakers.
FAQ — Bel Canto e.One DAC2.8
Can the Bel Canto DAC2.8 connect directly to a power amplifier?
Yes. The DAC2.8 includes variable 24-bit volume control and both balanced XLR and RCA analog outputs, allowing it to function as a DAC/control preamplifier connected directly to a compatible power amplifier.
What is the maximum digital resolution of the DAC2.8?
Bel Canto specifies support for PCM audio up to 24-bit/192kHz through AES/EBU, coaxial S/PDIF, Toslink optical and asynchronous USB 2.0.
Does the Bel Canto DAC2.8 support DSD?
The DAC2.8 is designed around 24-bit/192kHz PCM conversion. Bel Canto's published DAC2.8 specifications do not list native DSD playback, so DSD files should be converted to compatible PCM by the source software before playback.
Does the DAC2.8 have an analog input and headphone output?
Yes. The DAC2.8 includes one stereo RCA analog input along with a dedicated front-panel headphone amplifier capable of up to 4.5Vrms and 300mA output.
