TE8802 USB to I2S / Coaxial convertor (Built in USB power supply, can accept external power supply. Have both I2S and coaxial output) USB Audio Class V2.0 and V1.0 USB Audio Class2 High-speed Input from PC/MAC (Windows XP, Win7 32bit /64bit, MAC OS ) Supports full/high speed Asynchronous Transfer Mode Resolutions support 16 / 24-Bit with sampling rate support 44.1kHz, 48kHz, 88.2kHz, 96kHz, 176.4kHz, 192kHz Built in USB power supply , support external power supply I2S output and coaxial output at same time Price : USD40 (without shipping cost, include TE8802 kit X1 , wire X2, RCA socket X1 ) Please note: 1, If applied external power supply, must pull off the two jumpers on the board, see the photo as below : 2, The TE8802 upgrade kit want to have some few soldering during upgrade, so the upgrade require users have well solder experiences. 3, If users have wrong wires connect between main board and the kit maybe shatter the TE8802 chip within few seconds, so the kits without any guarantee ( We will test and ensure the kits working well before shipping) . 4, The TE8802 upgrade kit spend 3.3VDC / 150MA , please ensure your devices have enough power supply before purchase . There is no problems of audio-gd products.
USB power supply setting : (Users can place the kit at outside as an USB to I2S/coaxial converter. If place in the gear but the gear have not enough power supply , users also can use USB power supply . )	External power supply setting:	Best performance modify advice: (Users can setting the TE8802 kit on external power supply model, connect a class A PSU module PSU-A for the power supply , boost the sound level to highest performance. In this model the TE8802 still have power from USB through the PSU-A .) PSU-A link: (If order for TE8802, must inform while place the order) http://www.audio-gd.com/Pro/diy/PSU-M/PSU-AEN.htm
Design: Since November 2011 we have finished the TE8802 design and start 10 pcs TE8802 samples test. At 15th December 2011 , we had order the first batch TE8802 . The Tenor company Chinese general agent declare they have limit release the TE8802 carefully, only accredit to few manufacturers can produce TE8802 products, and promisesed we are the first manufacturer produce batch products applied TE8802 in Chinese Mainland . While we start design the PCB, we were consider the TE8802 running at 192KHz high sampling, it need good power couple to keep it working well and stabilization , so we design every power supply pins has applied 1UF with 0.1UF in parallel connection , and there are 4 pcs 100UF caps place on different parts of TE8802 power supplies. For the caps can shortest connect to the TE8802 power supply pins, we design the caps on bottom side, the wires between the TE8802 pins and the caps less than 4MM length, guarantee the TE8802 working well and stabilization , reproduce the detail .

Please note before modify:
       A ,   If make any wrong operate during modify, maybe shatter the TE8802 kit or the gear within few seconds , so must made sure the modify have not any wrong before power on it for the test . If you can't make sure the modify, you can send email to king-wa@hotmail.com , we will reply the email within 2 hours in work time.
       B , Before take off the top board of the chassis , MUST make sure the power cable had been pull off .
       C ,The modify don't need take off the board. Cut the parts and solder the wires on top side have not matter.
       D , The DIY modify have a lot states, so we will test the kit before shipping and have not any warranty .
       E , If you want modify the gear have I2S input instead USB input , connect the wires number 3 to 7 ( GND , MLCK , BCK , DATA and LRCK to I2S input kit ) .
       F , If below have not guide you need, please send email to king-wa@hotmail.com , we will update the guide as soon as possible .
　

For DIYer modify in non-audio-gd gears :
       A , The pins define as the photo on right side . The output format is I2S 24bit.
       B , Few parts install can allow the kit output coaxial signal .
       C , The power supply for the TE8802 must be +3.2 to +3.35V , 150MA idle current spend .
       D , Connect the wires have wrong maybe shatter the kit within few seconds.
       E , The one hole for install struts but had connect to GND , make sure your gear allow the kit connect to GND to chassis . You can cut the wire on the kit to let this hole don't connect to GND .
　

Upgrade in NFB-2 & NFB-2.1
Step 1: Cut the extra parts on the board . A , Cut the 5 resistors as the No.1 and No.2 in the photo on right side . B , Addition a resistor (4.7 ohm) on the either resistor in the No.3 . C , The wires number have mark on the TE8802 kit photo.
Step 2: Connect the wires . The wires number had mark on the photos , must connect correct .
Step 3 : Solder a resistor ( 4.7 ohm) as the photo . The NFB2, NFB2.1 have class A PSU, this resistor is for boost the current of the PSU . If users install I2S instead TE8802 kit, this resistor must take off .
Step 4 : Take off the original USB socket board and struts . Install the new two struts on here . The struts is made by handwork, so even we are try our best but maybe have little error . I beg you understanding .
Step 5 : Install the kit . Push into the wires on the kit and finished . If the wires have not any wrong connect, you can connect the PC and enjoy the music at next steps .

Upgrade in NFB-3 & NFB-3.1
Step 1: Cut the extra parts on the board . A , Cut the 5 resistors as the No.1 and No.2 in the photo on right side . B , The wires number have mark on the TE8802 kit photo.
Step 2: Connect the wires . The wires number had mark on the photos , must connect correct .
Step 3 : Take off the original USB socket board and struts . Install the new two struts on here . The struts is made by handwork, so even we are try our best but maybe have little error . I beg you understanding .
Step 4 : Install the kit . Push into the wires on the kit and finished . If the wires have not any wrong connect, you can connect the PC and enjoy the music at next steps .

Upgrade in FUN

Simply pull off the original USB module and push into the TE8802 kit . Before power on it, users want to screw on the screws for confirm the install is correct .

Upgrade in DI-B We don't recommend modify for the DI, because : 1, The DI have small size, the kit only can place at outside, through the long wires connect at inside. 2, The modify can't arrive the same level of the new DI, the new DI applied 2 groups class A PSU separate power supplied for the core and the I/O parts of TE8802, the modify only applied 1 group class A power supply for the whole TE8802 .
Step 1: Cut the extra parts on the board . A , Cut the 2 resistors as the No.1 and No.2 in the photo on right side . B , Remove the tins in No.3 as the photo.
Step 2: A, Addition a 5.6 ohm in the DI as the photo . B ,Connect the wires . The wires number had mark on the photos , must connect correct .

Upgrade in DAC-19DSP
Step 1: Cut the extra parts on the board . A , Take off the DSP-1 careful, don't break the pins . B , Take off the USB socket as the No.1 in the photo. C , Cut the 5 resistors as the No.2 and No.3 in the photo on right side .
Step 2: Connect the wires . The wires number had mark on the photos , must connect correct . Install the DSP-1 correct .
Step 3 : Install the new two struts and the TE8802 kit . The struts is made by handwork, so even we are try our best but maybe have little error . I beg you understanding .
