- DI-2014 had built in ultra high performance power supplies, include 5 groups class A PSUs, the class A PSUs had ultra high input impedance and low output impedance can block the disturb through power supplies effect the sound quality.
- DI-2014 had applied 3 groups PSUs supply the USB-32 DSD chip, separate power supply for the core, I/O, PLL and clock. These processes made the performance and sound quality had much improved. Especial the clock and PLL power supplies, applied the negative-feedback power supply (PSU chips or some Linear PSUs) or power supply common with other circuits will make the phase noise increase to large level and much degrade on sound quality. Our all class A PSUs are non-feedback design.
SPDIF input controller chip had separate class A power supply. The Power supply is the source of anythings in audio world!
Not connect the +5V line for less interrupt from computer USB.
Ultra short signal journey design, all the signal through only one stage high speed and strong drive ability logic chips, can avoid signal delay and the digital wave smooth off.
- Ultra fast Audio USB Class 2 compatible with Windows / Mac / Linux
- USB - chip VIA Vinyl VT1731 ( PCM 32bit/384kHZ i DSD/DXD)
- USB conversion to I2S output support 16 / 24 / 32-Bit ， 44.1kHz, 48kHz, 88.2kHz, 96kHz, 176.4kHz, 192kHz , 352kHz , 384kHz
Support DSD64 / 128 from I2S output
Two model coaxial outputs * :
BNC (Applied Current Conveyor Technology,support up to 16 / 24-Bit ， 44.1kHz, 48kHz, 88.2kHz, 96kHz, 176.4kHz, 192kHz)*
RCA (Transformer Transmit insulate ,support up to 16 / 24-Bit ， 44.1kHz, 48kHz, 88.2kHz, 96kHz, 176.4kHz, 192kHz with most DACs except the Master 7 support up to 96K)
- The Current conveyor output can cooperate with most standard design DACs in world but some DACs can't cooperate . The transmit insulate model output can cooperate with all standard design DACs.
- Interface/converter USB 32bit/384kHz (PC/Mac) to S/PDIF Coaxial.
- SPDIF coaxial/optical Input for for revitalization digital signal from other source with SPDIF Output
- S/PDIF Output: Coaxial RCA and BNC with I2S on RJ45

Please note: Don't hot push / pull of the I2S cable. Any time must power off the units then push or pull the I2S cable.
3.3V level can't guarantee the I2S input can cooperate with all I2S output devices.
The I2S transmit want to cooperate with the ethernet transmit cable.
