|Audiophile sound anywhere you are .......|
The second generation portable USB/SPDIF DAC has R-2R resistor ladder multibit multiplying current-output DAC chip LTC2753 from Linear Technology Corporation and for today in spite of it small size 65/85/14 mm appear a top of more microdetails (resolution) and sound fidelity from DAC's made and make on this planet.
Operational of DAC
An available SPDIF (20-100KHz auto) TOSLINK or wire (RCA) as source for signal for DAC. If source of spdif is PC or laptop as can to adjust the volume from PC or laptop in application window or/and bottem bar.
If source of spdif is CD/DVD Players or Portable players, as some Players has a volume adjust and some not. You need for adjust possibility. For use spdif source you need powered the DAC by "USB mini PWR power jack".
An available USB (48K/16b) from PC or laptop. Plug USB cable to DAC, either mini or micro. No need a special driver because all major OS has reliese USB Audio 1. In general USB of PC or laptop has a sufficient power for powered of DAC, therefore to add additional power by "USB mini PWR power jack" is senseless. For USB release the volume can to adjust by open application window(for WIN10). Unfortunately some sites in internet has incorrect volume behavior or unadjust volume ... sad .
USB On-The-Go (OTG):
Almost all TABLETs has USB On-The-Go. Unfortunately not all smartphones has USB On-The-Go. For instance: LG has a model LG X power 2 that is support USB On-The-Go. For SAMSUNG here is list of support USB On-The-Go. This DAC is a more 100 mA power consuption, therefore some USB-OTG devices can to support it self and some can't. In any cases you can to connect to PWR power jack additional power for solver it problem. (Please note: USB-OTG protocol exchange a bit complicated then standard protocol exchange of USB, plus old version drivers can to appear to stall of USB bus. For avoid this situation we recomend to us next 2 rules. 1) Do not plug or unplug USB and USB PWR power cable when the DAC in power ON. 2) Do not switch OFF the DAC before you pause/stop or close application on source device. ........ If you anywere enter to stall as you need to stop an aplication on source device and close it. Start aplication again)
