Overview The Rolls MX22s is a small 2-channel audio mixer. It has two inputs, channel 1 is a mini-plug stereo input, and channel 2 is a stereo RCA input. Both inputs are for line-level sources (not microphone inputs). There are level controls for both channels, and two separate outputs, one being a stereo mini-plug and the other a stereo RCA. The MX22s is a great problem solver in many different applications. It can help when you connect devices to a home entertainment system, and you have more devices than inputs to your A/V receiver. You can connect a CD player and the output of an MP3 player on the MX22s, and mix them into a single input on the home entertainment system. With the Hosa HPE-310 cable, it has sturdy molded connectors and a durable outer jacket for long-term use.
