DAC/Preamp

The EX DAC/Control Preamplifier is built around our High Dynamic Resolution HDR-II core and high-speed Asynchronous Multi-Input Processor (AMiP) platform that defines the most versatile DAC preamplifier. Stream music through Ethernet or USB, a full suite of digital inputs, line level inputs, sub output and software controlled internal MM/MC analog phono stage.

The EX DAC is designed to manage the complexity of all audio source and control functions with ease and efficiency. The 32-bit volume and multi-processor system functions are controlled by manually pressing and rotating the control dial on the front of the unit, or by using the IR custom remote control, or with your iPhone/iPad and the custom iOS app. The fully programmable display is easy to read and illuminates system status indicating source and volume.
