The DI had both BNC
and RCA coaxial outputs can connect to two DACs at same time.
The both version DI has built in class A PSU can work well by USB
power supply ,The external power supply only for upgrade, not
The DI-DSP version spend around 500MA , some computer maybe can't
offer 500MA current through USB pot cause the DI-DSP can't working.
We test by MacBook, SONY, IBM and Sumsang notebooks without
The DI-V2 and DI-V2Scan power supply by the old Digital Interface
extern PSU, but the DI-DSP can't power by this PSU, customers if
have the old Digital Interface extern PSU and want to power supply
for DI-DSP, want to solder a resistor in it.
The DI-PSU (new) have different than the old Digital Interface
extern PSU, the DI-PSU (new) offer 600mA at 7.5VDC, the old Digital
Interface extern PSU offer 400mA at 7.5VDC .
Confirm with Tenor , the output sampling 176.4KHz and 192KHz
request the computer have high performance ( We recommend the PC
produced within latest 4 years) , and if in this term if the
computer have to running larger software or game cause the CPU
working too busy or stop response maybe cause the audio drop off .
If want to restart the DI, after power off , least 10 seconds for
the TE8802 reset is necessary .
What's different between DSP1 and DSP-3.1:
Both DSP1 and DSP-3.1 are based on the Altera Cyclone II chip, but we apply different software to perform
different functions. Both have data synchronization to reduce jitter.
DSP1 has a built-in high performance digital filter, it is only used
The DSP-3.1 is especially designed for
DI only, not
designed especially for DAC. It has built-in upsampling which allows
output up to 96KHz or 192KHz (In default setting, its output is the
original sampling), and designed for high speed SPDIF output, without
What's benefit of the coaxial input:
The coaxial input can improve on SQ
from some low/mid rang coaxial output source. Like some DVD player, PC
sound card, low/mid rang CDP like the Marantz CD67, ect. If the coaxial
output source already quite Hi-end, don't expect the DI
can improve on SQ.
