DAC-5

Dear user, thank you for purchasing our DAC-5 Digital D/A Converter. This is a specially-designed model for the
audiophiles who have high requirements on the sound-reproduction ability. As a high quality stereo Digital/Analog Audio
Converter of both 24Bit/96KHz and 24Bit/192KHz, it’s extremely suitable for the owners of VCD, DVD and CD player as
well as computer owners to upgrade their current audio system.
In order to improve the sound quality, Xindak engineers have also used patent technology on avoiding dynamic
invalidation of capacitors, which could decrease the distortion on the High especially. It can upgrade the digital signal
recorded in PCM format of common CD player to 24Bit/192Khz to achieve higher processing precision and highly improve
the dynamics and treble extension, making the sound more mellow with richer soundstages.
It adopts AD1852 24Bit/192KHz of AD company to convert digital data to analog data. The analog filtering circuit adopts
low-noise resistance and OPA2064 of BB company. The double annular transformers and six independent stable power
supplies can afford abundant and pure power to the circuits and ensure their most stable and best working status.
Additionally, it also corrects the Jetter time base errors at the same time. The 6922EH(JJ E88CC) tube for the analog
output amplifying to achieve exquisite and mellow sound.There are three output ports available: signal-terminal tube
analog RCA output port, OPA analog RCA output port and OPA balanced output port to afford various chooses for the
users.
