• Designed for maximum flexibility as output configuration can be optimised in systems with a wide variety of digital audio sources

• Dual crystal oscillators with microcontroller-enhanced temperature correction

• New dual frequency output and auto- clocking mode used in the Vivaldi and Rossini range improves ease of use and minimises jitter, particularly with computer audio sources

• Multi-stage regulation ensures sensitive clock and PLL circuitry is unaffected by digital interference

• Aerospace-grade machined aluminium chassis fitted with tuned acoustic damping panels reduces magnetic effects and vibration
