The Switchcraft SC600 Dual Adapter Box combines many of the most commonly used audio adapters into one, easy to use device. Each side of the box functions separately, and features a 3.5mm (1/8") stereo jack, a 1/4" stereo jack, two 1/4" mono jacks, and two RCA jacks.Any of the connections on the SC600 can be used as inputs or outputs, enabling you to adapt audio from one device to another. The SC600 can also be used as a passive splitter to send audio from one device to up to three devices with different connections. For example, plug the audio output of your laptop into the 3.5mm (1/8") jack, then access the stereo signal from the two 1/4" mono jacks and the two RCA jacks. This would enable you to run audio from your laptop into a mixing console or house sound system and a cd recorder at the same time.
