E1DA Power DAC V2.1 Headphone Amplifier PEQ DSP BLE DAC with 2.5/3.5 Adapter, Type B to A Cable
【Small But Powerful-Upgraded Version】
PowerDAC V2.1 is the newest version and is pretty much the same as the Power DAC V2,except that the V2.1 version can now also handle unbalanced headphones.In addition, PowerDACv2.1 received a new USB audio bridge CT7601 Comtrue, instead of Cmedia, which was far from ideal.
【Three Output Modes】
The HPToy iOS / Android app has been modified to provide a switch for 3 output modes:
1) balanced - same asPowerDACbalanced 2.5mm TRRS up to 600mW / channel output
2) unbalanced - you can use this mode with E1DA 2. 5 / 3.5mm adapter in order to drive your unbalanced headphones, however, the power in lower mode vs balanced mode
3) unbalanced charge - the same as unbalanced with 600mW full power, but with some cross-feed effect. This price is to help create one 2.5mm TRRS output
【Soft Start Function】
PowerDAC 2.1 has a soft start function to avoid high current, in fact, PowerDACcan works with any Android phone without a y-splitter if you want to use such a power-hungry device with your phone.
【Easy Operation】
The PowerDAC V2.1does not require drivers to convert PCM stream up to 24/192 from PC / Mac. iOS, Android, or Linux, however, if you want full control over the built-in DSP, you need to install the iOS or Android app. With the app, you can get volume slider with classic Fletcher-Munson volume curves and familiar HiFi bass / triple sliders.
【High Sound Performance】
With the app,PowerDACowns intuitive filters, i.e. 7 parametric EQs and the compressor /limiter,which is really useful for an open backboard to "compensate" for ambient noise. And the limiter keeps the sound without distortion at high volumes, also you can see the cutout indication on the output in the app.
