Bluetooth 5.0 LDAC Transmission
D90LE has the certification of Hi-Res Audio Wireless and LDAC, which uses CSR8675 chipset to support LDACIAAC/ SBCIAPTX/ APTX LL/ APTX HD protocol. To get even better sound quality from Bluetooth, we abandon the built-in DAC of CSR8675 but connect its digital signal to ES9038PRO to decode.
Flagship ESS9038PRO Chip & 2nd gen XMOS
D90LE features flagship ESS9038PRO chip and 2nd generation XMOs, meaning USB can support up to PCM32bit768kHz and DSD512 native. With the help of customized Thesycon ASIO driver (for Win 10 and above), your PC will serve as HIFI source. Besides, IIS input can also support up to PCM32bit768kHz and DSD512 native. When there is a better interface, you can use the HDMI cable to directly send the IIS signal into the D90LE's EsS9038PRO for better decode. The IIS input provides phase settings, DSD channel settings, and DSD indicator pin selection settings, which are compatible with most digital interfaces on the market that use the HDMI interface to output IIs signals.
XLR 4V/5V & RCA 2V/2.5V Selectable Output
D9OLE characterizes balanced XLR output and single ended RCA output. There are three outputs, including "XLR only" "RCA only" or "XLR+RCA" to for different applications. In addition to the more versatile XLR 4Vand RCA 2V outputs,there are also extensive needs for XLR 5V and RCA 2.5V.D90LE adds options to set this to meet more needs. When XLR 4V and RCA 2V are selected,it can adapte more devices; when choosing XLR 5V and RCA 2.5V ,the performance will get from extreme to more extreme.
DAC Mode & DAC + Preamplifier Mode
ln addition to the DAC mode with a fixed output level, the D90LE also has a DAC+preamplifier mode, which you can control the output volume on the front panel or remote control. It will facilitate you when connected to a power amplifier or monitor speakers. And also help you leave the budget for a preamplifier.
Designed to associate with A90
A90 is a fully balanced discrete NFCA module, which is recently launched by Topping, featuring ultra-high output capability, 0.000055%ultra low THD+N. 0.1-ohm output impedance, wide gain setting, high output voltage, almost suitable for driving all kinds of headphones.
