USB Powered 384kHz/24bit PCM and DSD-256 Galvanic Isolated Audio DAC Based on XMOS and Asahi KASEI New Generation Premium "VERITA" AK4490 chip. Main features:Only high quality components used, from the world known companies and reliable suppliers: Xmos, AKM, Silicon Labs, Texas Instrument, Analog Devices, Elna, Nichicon, Murata. Panasonic 0.1% thin film resistors in analogue circuit.
* - Phone
output is additional, for high quality sound use RCA with external head
amplifier. If use Phone output don't forget to enable the digital
volume control in your player. ** -
Using with cellular phone or tablet will quickly discharge it's
battery, so using external power supply is recommended. Also if you want
to use very long (>1.5m) USB cable. ATDAC-8A power consumption is about 0.55A, which is a little bit more then the regular USB port provides according to the standard. But I never seen USB port, not satisfied ATDAC-8A with it's current, at least with the short (<0.5m) USB cable. However, it is better to use USB cable as short as possible. Also do not use very thin USB cables ("Chinese no-name"). *** - External power supply requirements: 5VDC (+0.5, -0.2V), 0.6A at least. Pay attention - internal pin in the DC connector is "minus". Reminder - ATDAC-8A output is primary dedicated to amplifier connection. If
you want to use headphones, use external high quality headamp. Due to a
lack of power which can be consumed from USB, DAC's Phone Output sounds
good just at the low volume. ATDAC-8AM has better performance at headphone output, but as the power is limited - no way to use low impedance (16 Ohm) headphones! Also with high impedance (600 Ohm) headphones and low sensitivity, there may be a lack of volume. There is no problem with most 32-250 Ohm headphones. A new, ATDAC-8AX model is ready. AK4493 instead of AK4490. That's all. |
