Reference DAC Digital Media Bridge
The Reference DAC is designed to be a digital-to-analog converter with state of the art sound quality, and also to accommodate the ever-growing formats used in todayÕs digital world. Combining unparalleled digital connectivity with renowned Audio Research vacuum tube technology makes the Reference DAC a leader in the world of high performance music reproduction.
The experience begins with the intuitive graphic interface, guiding the user easily through input selection and the appropriate menus to begin music playback. With nine different ways to connect, plus a built-in internet radio tuner, virtually all digital sources in your system are connectable to the Reference DAC. Inputs providing metadata will allow track and album information to be displayed. All functions are controllable with the included remote or from the available iOS/Android smartphone or tablet apps. The Reference DAC has been designed to decode virtually all major formats to provide trouble-free music playback.
At the heart of the Reference DAC is Audio ResearchÕs custom designed quad DAC technology supplying perfect decoding of the incoming bit stream. The Reference DAC is capable of up to 192 kHz sampling frequency and 24 bit resolution; it also offers the option of native rate upsampling (44.1 _ 88.2 _ 176.4 or 48 _ 96 _ 192) and soft or sharp digital filter selection. After the signal is decoded it enters the analog stage. Derived from the esteemed Reference 5SE preamplifier, the vacuum tube analog stage and tube regulated power supply provide the pinnacle of nuance and musicality. The built-in volume control allows direct connection to an amplifier.
The Reference DAC is poised to be at the center of your audio system and the pulse of your digital lifestyle. The convenience, ease of use and superior performance of the Reference DAC will provide years of enjoyment.
