DAC 2496 (AK4393)+CS8416+AK4393+5532 Kit
It need over 30 days to Italy,if you care the shipping time,please don't bid.If you need the tracking number,please pay me more 5USD. If you need post it by DHL,please pay me more money.
This is a kit,you need to sold it by yourself.
Chip solution: CS8416 + AK4393 +5532
Size: about 80mm * 80mm
Power: Dual 13-15V + Single 9-15V or dual 13-15V only
If you want to buy this R transformer.pay me more 39USD.It can work at 110V or 220V.
● Have a common status indicators:
1. Power indicator
2. 96K coaxial input signal sampling rate will be greater than or equal 88.2K when lit.
3. ERROR, when not locked coaxial signal comes on, usually not connected to the coaxial signal, or coaxial input the wrong signal.
4. NO AUDIO, some of the home players have DVD player can also use this decoder to enhance the DVD player output disc CD player sound quality, while some of the common 2-channel sound track of DVD discs can also be decoded. When the DVD of the coaxial digital signal output to MINI2496 than 2 channel PCM data, when the lamp lights, while MINI2496 into silent mode, no mute function decoder receives the digital signal to DTS or AC3 to lose time digital noise.
● MINI2496 Just use a dual-AC13-15V power supply and a set of AC9-15V single power supply. Can also short the PCB on the back of the two pads, so a dual-AC13-15V power supply can work. Reduces power requirements. Transformer can be greater than 10 watts.
The main parameters
● expansion of the chip with options.
Digital receiver with excellent performance, stable operation of the CS8416. Also opens the jitter function to the chip itself (that is, JITTER elimination), CS8416 SPDIF to the IIS in the completion of the converted signal is passed directly to the IIS core DAC signal conversion chip AK4393.
AKM AK4393 Japanese company produced the best DA converter chip, the company's products to begin with AK in the DIY sector is not as TI BB AD Philips also known, but in an external sound card, professional recording equipment, which is very common. ECHO's GINA2496 external sound card such as, the price of 3K or so, use is AK4393. External sound card RME FF400, innovative EMU0404 are named on the chip using the AKM. Which uses the AK4395 EMU0404 to this model.
As AK4393 AK4394 AK4395 AK4396 models are compatible with each other, so MINI2496 also has a high playability. Among the most outstanding performance AK4395 No wonder EMU404 sound card will use.
After AK-chip analog signal and then convert them into the NE5532 dual op amp such commonly used form of the LPF circuit is equipped with high-quality IC socket Seiko Mausoleum, you can easily replace such OP275 OPA2604 LM4562 op amp such as changes in taste.
● Simple, but not diminished the power program, the digital part of the use of a low ripple voltage level 2, using 78 79 amplifier consisting of a regulator sound more lively. At the same time on the CS8416 DAC chip and use their own patch VD VA 1117 power supply with separate supply, digital power supply with two chips are separated beads and so on, while next to each active device has a separate decoupling capacitors This is good for mixed circuit must have the condition.
First, three welding IC:
Then weld the three 1117, 2 of which only 1 is 5V, 3.3V
Support elements in accordance with the order from low to high, the first welding resistance and diode, two beads are not welded on the first
Then welding Promise capacitors, connectors, voltage regulator block, IC Socket
Finally, weld the main filter capacitors, decoupling capacitors. LED has 2 choices, solder or connect the board to the panel, so the final welding.
Power before checking whether the wrong polarity of the capacitor in order to avoid fireworks.
After the first measurement of the transformer connected to the power regulator IC output voltage is normal, 78157915 red table pen measured from the positive side the far right of a pin IC, the black pen Ground
1117 can be measured directly below the top of the middle of a large pad or pin.
Voltage of each group of two normal weld beads, respectively, on the PCB L1 L2
Inserted after the power measurement IC luck put out the midpoint, there are several millivolts of offset that is normal.
OK, wiring audition
RMAA test on the points
Test the sound card is EMU1212
