The E1X DAC/Control Preamplifier utilizes Bel Canto’s proprietary technologies that include our advanced HDR-II (High Dynamic Range) DAC core and the AMiP (Asynchronous Multi Input Platform). Our advanced design provides uncompromised sound from any source. Whether you’re streaming music through Ethernet or USB, using the full suite of digital inputs for spinning a CD, the line level inputs for a reel-to-reel tape deck or listening to vinyl via the internal MM/MC software controlled analog phono stage, you’ll experience the full potential from all source components. tape deck or listening to vinyl via the internal MM/MC software controlled analog phono stage, you’ll experience the full potential from all source components.
The E1X DAC is designed to manage the complexity of all audio sources and control functions with ease and efficiency. The volume and system functions are controlled by manually pressing and rotating the control dial on the front of the unit, using the IR custom remote control, or with your iPhone/iPad and the custom iOS SEEK app. The E1X is also a Roon end point giving you the option to subscribe to Roon for network streaming to the Bel Canto platform. The fully programmable display is easy to read and illuminates system status indicating source and volume with auto off function when not in use. It also displays all programming functions.All source inputs are asynchronously re-clocked into the fully balanced advanced segment DAC measuring below 0.001% distortion and 126dB of dynamic range. By stripping away the source clock and using Bel Canto’s custom Ultra Low Noise master clock circuitry we eliminate jitter and data related distortion, preserving the delicate audio signal.
Asynchronous Digital SPDIF AES, RCA and Toslink inputs all operate at 24/192Ks.
Asynchronous USB2.0 Audio is compatible with any PCM source up to 24/348, MQA, and DSD 128 (DoP). Windows-based computers require our custom driver. USB2.0 works natively in OSX.
MQA (Master Quality Authenticated) is an award-winning British technology that delivers the sound of the original master recording. The master MQA file is fully authenticated and is small enough to stream or download. Visit mqa.co.uk for more information. The MQA logo is a trade mark of MQA Limited. © MQA Limited 2017
RS232 is designed to support easy integration with sophisticated whole house control systems.
The line level analog input also can be programmed to gain match your analog sources and achieve the best performance from all analog sources. The line output can be connected to a powered subwoofer.
