Radial Engineering MIX 2:1 2-Channel Passive Mixer

The MIX 2:1™ is an incredibly useful mixer. It passively combines two audio channels into one, allowing you to effortlessly convert stereo outputs from a console, recording interface, or portable playback device to mono, or mix any two signals and adjust their input levels. Whether you're using two microphones on a guitar amplifier or the stereo line outputs of a mixing console, this mixer makes signal summing a breeze. It offers both ¼' TRS and XLR connectors at the inputs, along with ground lift switches to get rid of buzz and hum from ground loops for noise - free operation. Each input has a trim control, so you can attenuate separate mono sources as needed to match output levels. After the signals are combined, they go to a single XLR output that can be connected to a powered speaker, console, or recording interface. Key features include mixing two channels to one mono output, the option to bypass individual level controls when not needed, balanced 1/4' TRS and XLR inputs, and it's completely passive, no power required.

Using the MIX 2:1 is straightforward. First, connect your audio sources to the inputs. You can use either the ¼' TRS or XLR connectors. If you notice any buzz or hum, use the ground lift switches to eliminate it. Adjust the trim controls on each input to match the levels of your sources. This is especially useful when you're using two different mono sources. Once your sources are connected and levels are set, the mixer will passively sum the signals and send them to the single XLR output. Connect this output to your powered speaker, console, or recording interface. As for maintenance, keep the mixer in a dry and clean place. Since it's passive, there are no internal power components to worry about. But make sure to check the connectors regularly for any signs of wear or damage. And when not in use, you can store it safely without having to worry about power consumption.
