Rated 4 out of 5 by from Good valueVery versatile DAC. Decent SQ. Defiantly better than the audio output that comes with the MacBook Air. RCA out from this DAC is weak though. I wound not use it for my main source of audio but it is what it is and it makes me happy. Thank you PE.

DAC Digital to Analog Audio Converter Optical / Coaxial / USB

So can i plug the sound from my ps3 or ps4 to my old amplifier with the dac?

Asked by: Anthony39
Yes, you would likely need to use an optical output on the PlayStation, and it would convert to analog for the receiver.

Does the headphone amplifier only route through the headphone out? If not is it okay to use this DAC in a stereo speaker set up with an external amp as opposed to using it with just headphones?

Asked by: Rohit12789
Yes. This is an Digital to analog converter and the RCA connections can be used as inputs to your amp. It signal can be monitored through the headphone out.

Would this work if I connected it to my BOSE Sound Dock2?  It only has an Aux In.  So in essence I would be going from my television (optical) to the BOSE speaker (AUX). Thank-you.

Asked by: dirk784
Yes this will work for that application, as long as the output on the TV is set to PCM.
