A: The specs on the ART HeadAmp 6 show 150mw with headphones of 8 or 600 ohms. It also states much higher power (500mw) with 32 ohm headphones.

Q: 10. HI! Since Windows 7 and 10 do not have multichannel output (only 2 channels can be heard), I decided to work 2 8 channel sound cards simultaneously. I am a composer and want to compartmentalize the orchestra into 16 distinct channels using software that would let me do that. Sound source will be taken from their analog outputs. This is why I am looking for 2 8 channel amplifiers. Can this be done with the Pyle? Thank you, John

A: If your audio interface or sound card has 16 outputs outputs, you can then connect them to the 8 unbalanced RCA stereo pairs on two of these amplifiers, and then send the signals out to passive speakers.
