The 5.1-channel decoder to be connected or 5.1 multimedia speakers amplifier can only be used

When the real direct computer USB 5.1 sound card with hardware decoding, the effect is never more than a thousand dollars difference between the onboard sound card.

We can compare several online decoder to the use of materials from the work are unmatched (on Taobao than it is now the same price decoder several other full high a grade), Ha ha!

Solvable AC3, DTS, HDCD, PCM, DTS CD, AC3 EX, DTS ES, etc. must now available in most of the disc format, Note: after the two kinds of AC3 EX, DTS ES is a 6.1 format, the decoder solved to 5.1 channel output, less a post in the home, the voice of the points in the home after a bad wound to the left and right channels.

Play real AC3 DTS to DVD movies and not to poor results than the cinema, the owner of 10.1 Tianhe, Guangzhou City, the National Day to the cinema to see and must have no effect to my decoder’s true (hey, since advanced is a small room, I do not know the effect of the hall will not better), if it is released horror film, I think you best companionship, ha ha, never on the immersive. horror.

Decoder chip is the most left line with domestic U.S. Crystal (Crystal) of the top dual-decoder chip (CS493263-CL + CS4360-KQ, the output of low general JRC5532, sound quality)

The decoder can be said for the time being on the market this price, the most complete, best quality, most solid materials used a full-featured digital audio decoder problem, I believe we see at a glance this machine materials friends , 6MM brushed by the chassis panel, steel is the metal used 1MM (professional-grade fever, but the chassis is also the case), the output stage delay relay do on (the market is temporarily not seen such a treatment) , the benefits of doing so in the startup and shutdown, do not have to worry about the impact of the sound, do not you love to act as the expense of horn products, in order to ensure the long-term stability of the machine work, using up to 8 group, regulator voltage transformers with EI shield of the transformer, panel key uses aluminum car system, high-end fashion, using custom NOVER (professional enthusiast) capacitor as a filter capacitor (high-frequency low-impedance series), the other electrolytic capacitors for Nikon FW series. grade 6 sound channel volume IC, the output with the former level and low-pass filter, with the servo power supply, 4 JRC5532.MP3 direct election songs, can significantly
Said playback time, the current track, the total tracks and so on. Special custom VFD screen can show all of the information, but also with a 10 P frequency display mode. (There ….) the more widely used in all, the back of the chassis Setting a bit special preamp switch, you can freely choose whether or not with a preamplifier, all functions were all written in the manual,

The decoding apparatus the following features: (a little brief details on functions, and how to use instructions, see the local support)

All-aluminum oxide drawing black shell design, better quality is very good.

The characteristic voice of DAH1 MARK II : The sound is strong and real,it can analyze the slightest details, give full play to the dynamics and the scene in great details.The sound is fine,delicate,smooth,sweet and natural.The headphone output of the machine can drive the majority of traditional headphone directly to achieve better results.The impedance of the former output is also low,with a power amplifer,it can be more easily to drive the speakers.

The DAH1 MARK II is specially designed by YULONG Audio engineers.The concept is that you need not any sound resource,if you have a PC,you can connect the machine to drive the headphone,power amplifiers,or speakers directly to achieve the best sound.The users can save the cost of sound resources,interconnect cable,preamp and headphone.

The main chip of this DAC Amplifier is AD1955 in which we have many years of practical experience. AD1955 is widely known for its excellent sound performance and its performance indicators is the best now.The circuit structure we learn from is as follows:DA1955 audio decoder,DAH1 multifunction audio processor,DAH1MARK multifunction audio processor and headphone drive circuit designed by YuLong Audio engineers meticulously. The working state is controlled by the CPU and displayed with the LCD. So it is easy to operate.The components we used are the best,such as the refined aluminum shell,gold-plated USB interface, RCA interface, headphone interface, dedicated audio OPA2134 and the import high-quality components with the fanciers class(different from the staking of DIYER,we have many years of design experience about these components).We use the advanced solid capacitor PAS and SEP which used in the high-end computer’s motherboard to supply.

DAH1mark II is an upgrade product based on the former two generations products.
1/Use SMD components, the PCB redesigned completely takes the spider-type grounding wiring method, the signal to noise ratio is very high,left channel and right channel are completely symmetrical, the ground wire is separated, the channel can work independently, so that you can hear the analysis of very high intensity, quiet background, and good separation.

2/The drive circuit of headphone is also redesigned,it uses PHILIPS tubes to match with the sound parameters we adjusted carefully and the components we selected carefully. The sound effects is fine and tender,natural,without losing the dynamics and drive capability.

3/Fully use the import J SMD components in the produce and we achieve the better sound quality perfoumance(A package of an ordinary K SMD capacitance sales 30RMB,while the same quantity and same function package of the import K SMD capacitance sales 1000RMB).

4/We cancel the electronic volume control for it can make some small noise,now we replace it with the imported high-precision potentiometers.

5/We cancel the LINEOUT port and add the balance output version (optional).

6/We cancel the functions of preamplification and remote control,now we focus more on the sound effort.

7/We add the pure DAC mode so as to improve the quality of the machine.

Because DAH1 MARK II uses the high-performance solid-state capacitors, it doesn’t work its the best state until the power is on for some time.

The new machine may be a slight sense of roughness, please keep the power on for more than 200 hours to listen again.

Functional operation modes:

1. DAC + headphone amplifier: Switch on the power, press MODE button from the front panel to select various input signal(SPDIF,Coaxial,USB), adjust the volume, plug in the headphone to PHONE and start to enjoy the music.

2. DAC: Switch on the power, press MODE button to select the input signal, adjust the volume to the left to the minimum to turn off the headphone amplifier,signal output from the R OUT L.

3. DAC + Preamp : Switch on the power, press MODE button to select the input signal, signal out from the PHONE through 6.35-RCA port.

4.Balance Decoding mode:(Required to purchase,the standard version is RCA output)THE operation is the same as the RCA version, the output mode is the balance (XLR) port.

Notes:If the sound card is used as the diginal input or USB input,please adjust the volume and waveform to the medium in the PC,if you adjust to the maximum,the output distortion of the sound card is also the largest,it will affect the performance of the machine.

The DAH1 MARK II uses 220-240V AC voltage as the standard input voltage,if you want to use 100-120V AC voltage, please note us before you purchase it.

Here’s what distinguishes the Audigy2 Platinum eX from the Audigy2 Player/Platinum:

1. Apart from 48 kHz and 96 kHz the digital-out got one more mode of 44.1 kHz. (I must say that the Audigy1 also had it but the Audigy2 was deprived of it for some reason. Since the sound goes through double resampling in this case (44-48-44), it’s really doubtful whether such mode is needed.)
2. Three analog stereo inputs Line1/Mic, Line2, Line3 on the external unit, two having a jack-type connector, can work as three stereo or 6 mono.
3. The card’s redesigned. All inputs are moved to the external unit, and now there are only analog-outs for speakers left onboard.
4. Two firewire ports instead of one.
5. Changes are brought into the ASIO2 driver. Apart from 16/48 there is one mode for recording and reproduction – 24/96, which can be selected with a special virtual device.
6. Quality of demo programs is improved, the software suite is extended.
