Introduction:

With coaxial and USB input switch can be easily connected with the coaxial output of the CD, DVD or computer USB (the original sound card instead of computer music system composed of advanced multi-media).

USB conversion chip coaxial use PCM2704, shielding the other functions, whichever is the digital signal (S / PDIF). And the use of high-precision active 10PPM crystal quality has further improved.

Digital receiver is the BB company famous DIR9001, the maximum sampling rate can be received 24bit/96K digital audio signals.

Advanced 24bit/192K decoder chip Wolfson WM8740, with good musical expression. Many European and American manufacturers is used advanced audio!

Filter output is used for dual op amp RC5532DD, sounds thin and soft, elastic bass. And with op-amp socket, according to their preferences for different op amp.

AC AC9-12V input, multiple regulated power supply, (+-10V, +5 V, +3.3 V) both in terms of dynamics and tone have a very good performance.

ON (An Meisen), or National Semiconductor LM317, LM337, LM7805 Three-terminal regulator IC.


Rings precision metal film resistors, Imported high-speed fast recovery rectifier diodes, Advanced RCA output lotus pedestal, high-quality power, input switch.

 
Usage:

ā—† USB DAC use:

When you make the machines connected to the computer, please switch to the allocated, the computer will direct the board to the current default sound card, your original sound card will be blocked, you can play any audio in the computer software , The decoder board will direct reduction of the high-fidelity audio signals, you can access through the RCA output seat multimedia speakers or amplifier directly.

ā—† use of digital coaxial input DAC features:

When you are through the coaxial line so that the decoder board and dial the S / PDIF (coaxial) output, when connected, please switch upward, this time the Board determined using S / PDIF line input, you can put the DAC when Pure decoder to use, this machine will be a direct reduction of high-fidelity audio signals.
