Applications

Consumer Audio to PA System
The Media-1 is perfect for interfacing consumer audio electronics with pro PA and recording equipment. The dual phone, RCA and 3.5mm inputs on the Media-1 sum the left and right stereo channels to a mono output.

Standard DI For Instruments
The Media-1 works just like standard direct boxes for active musical instruments like acoustic guitars, basses, and keyboards. You can thru-put the signal to an on-stage amp while transformer isolation keeps things quiet.

Using with a DJ setup
The Media-1 is well suited to handle the type of audio generated by CDs and digital audio files. By isolating the source with the PA system you also eliminate noisy ground loops.
