• The is a broadcast quality A/D converter that provides exceptional audio accuracy and clarity with any audio source or style
• Superior analog performance fine tuned through audiophile listening practices produces very low distortion (0
• 0006%), exceedingly low noise (-135 dB) and remarkably flat frequency response (+/- 0
• 05 dB)
• This performance is coupled with unparalleled metering flexibility and programmability with average mastering level monitoring and peak value storage
