We have completed the new design. Amplifier a professional IC, the sound quality has improved so much, while power consumption are greatly reduced.Power Supply part of the revised rechargeable Ni-MH battery. Easy to replace.
Portable Wireless Headphone Amplifier & DAC
The transmitter, the receives digitized (USB and S/PDIF)stereo audio and analog stereo audio as input, Support uncompressed (16bit,48KHz)digital wireless transmission, DSSS digital modulation and demodulation, 2.4GHz ISM Band (Default frequency: 2412MHz, 2437 MHz, 2462MHz).
The Receiver (headphone Amp),Output stereo audio, The built-in lithium-ion battery is rechargeable(12V,2600mAh),All field-effect transistor (JFET+MOSFET) Class A amplifier,Operating distance is more than 100meter(328feet)
Test results:
THD at 5 V peak: 0.003%(300ohm load 1kHz)
S/N : >90dB
Separation: >80dB
If a good lossless wireless Headphone amplifier & wireless DAC, we are interested in? Thank you!
