The UD-H01 is a dual digital/analogue converter containing two BurrBrown DAC chipsets (Type 1795) and a Tenor USB Audio Class 2 Interface. Thanks to the high-quality nature of these components, digital audio data from an external PC is converted to an analogue signal in high resolution Hi-Fi quality using up to 32 bit, 192 kHz asynchronous conversion technology. The resulting analogue signal can be sent to either a set of active loudspeakers or to an external amplifier. The UD-H01 is supplied with both balanced and unbalanced audio output connectors and a headphone connector complete with separate volume control. Two audio inputs (digital RCA and optical) allow connecting additional sources i.e. CD or DVD player.
