Custom order options:

1, Custom order BNC input /output:
     The RCA coaxial input / output sockets can replace by BNC sockets , cost is USD10/per without shipping delay   .


2, Upgrade the TCXO :
      In the DI-V3 had one clock can be upgrade, upgrade to TCXO price +USD20.


For the old version PSU modify to power supply new DI-V3
DI-V1 version PSU : Addition one 10 ohm / 0.5W resistor as below photo .
DI-V2 version PSU : Take off the top two resistors ( four resistors parallel connect ) and solder one 10 hom / 0.5W as below photo .

　

3, I2S output / input kit price USD3 / pc : (If you want the I2S input socket kit please inform while place the order, the output and input kit is different)
Modify with I2S output :
( The wire length 100MM)
( 3.3V level , we can't guarantee the I2S output can cooperate with all I2S input devices.
( The I2S transmit want to take care the transmit cable )
( Based on the limit of the I2S transmit ,the I2S output of DI have not guarantee )

Pin 1 : SDATA
Pin 3 : LRCK
Pin 5 : SCLK
Pin 7 : MCLK
Pin 2,4,6,8 GND

Other upgrade options FYI:
         Please not:
         Before charge the battery, please turn the DI to OFF or USB power supply until finished and pull off the charge .
        The DI can't power supply direct from the battery charge .
         Exchange the power supply of DI, please push the switch of DI to "OFF" , after waiting least 10 seconds then push to another power supply .
         We only have sale the DI-PSU , we have not stock and sale the Lithium-ion battery or universal DC power supply .
         Connect a wrong polarity DC power to DI-V3 will shatter it within few second.

Lithium-ion battery
     Nowadays there are some lot Lithium-ion battery from web shop and price only around USD15 with a power charger.   A 7.4V / 5000mAH Lithium-ion battery can power supply for DI-V3 continuously working 16 hours with full charge. Two battery for exchange can keep the DI working whole day. Larger power ( voltage must is 7.4VDC) battery can power supply for DI longer time .

Universal DC power supply
Power supply by A GOOD QUALITY universal DC power supply possible improved the sound quality than some computer USB pot . The request of the universal DC power supply is output 5VDC to 9VDC (recommend 7.5V) , 1000mA power , with 5.5MM plug , the plug define is inside is DC +, outside is DC GND .
