Descrizione

(dal sito del produttore)

The DAC2.5 converts your digital media into music for the most direct connection to your amplifier. The DAC2.5 provides full system control and is loaded with features including an analog input. This allows you to experience your music through the convenience of a single component, eliminating the need for a preamplifier.

The Bel Canto Dual-Differential DAC2.5 Control Center features an outstanding 122dB dynamic range and our proprietary low noise digital to analog convertor core. Including five 24/192 digital inputs, 24/96 USB input and a 24/192 ADC analog input, the DAC2.5 integrates and controls all of your audio sources including an analog input for a phono preamp or Home Theater Bypass. The front panel features a single multifunction control knob that selects inputs and controls volume level for both the main outs and ¼” front-panel headphone jack. The headphone jack is driven by a dedicated DAC/Amplifier circuit that optimizes its output and eliminates any compromises in the main signal path. The DAC2.5 also includes our new 8 character alpha-numeric display and the ability to control balance, absolute phase and to rename and disable unused inputs.

The foundation of the DAC2.5 is our jitter-eliminating Master Reference Ultra-Clock circuitry that ensures that jitter from any source is reduced below the audible threshold. The 24-bit digital volume control is completely transparent and accurate throughout the volume range. This precision continues with custom 0.1% audio grade resistors, class-A output circuitry and low noise power supply components. The heavy-gauge all-steel chassis design prevents mechanical resonance from compromising the audio signal quality.

The advanced internal LNS (Low Noise Supply) prevents power line noise from corrupting the signal using technology developed in the VBS1 external power supply. The DAC2.5 connects directly to the mains AC with a standard IEC connection.

Green, low-heat, efficient isolated power supplies and a finely-tuned analog output stage make possible Bel Canto’s eco-friendly compact designs; Bel Canto music products are fine instruments that are musically satisfying, discrete and sleek to fit any room.
