Works great thanks

Great little audio mixer. Able to control audio from PC and Mini disc player into audio setup.

Works exactly as described. I used this to combine a drum trigger module with my iPhone and it works perfectly well. However, the attenuation of the signal is very, very high and therefore too quiet to use with earphones or headphones. Rather than spend additional money an a headphone amp, I decided to return this and buy a battery powered mixer which does exactly the same thing, albeit for twice the price; but still significantly cheaper than buying a headphone amp in addition to this.

It significantly lowers the volume even with the max volume. For some audio and devices it is simply not audible. But most mp3 and other devices works okay with max volume.

It only works with the ground loop isolator plugged into the output and it weakens the audio signals but apart from that i can not fault it
