Description
When you’re out of channels or need to fold a stereo signal into mono, the Radial MIX 2:1 solves the problem with nothing more than passive circuitry — no wall wart, no batteries, no fuss. Feed it two balanced sources and it hands you back one combined signal, ready for a console, interface, or powered speaker.
- Combines two audio channels into a single mono output
- Balanced 1/4″ TRS and XLR inputs on each channel
- Per-channel trim controls, with a bypass option for unity-gain summing
- Ground lift switches on each input to knock out hum from ground loops
- Fully passive design — requires no external power
The flexibility here comes from the input trims. Feeding it two separate mono sources, like a pair of mic preamps? Dial each one in until the levels sit right at the output. Just need to sum a stereo pair — say, an aux send or a playback device’s L/R outs — down to a single mono feed? Bypass the trims and let both channels pass through at unity gain.
Because both mic and line-level connections are supported, the MIX 2:1 covers a wide range of real-world scenarios: blending two dynamic mics on a single guitar cab into one preamp channel, combining two tracked signals down to a single interface input with a phase-flip to keep things coherent, or freeing up a console channel by summing a stereo source before it ever reaches the board. One thing to remember when working with microphones — disengage phantom power first.
It’s a small box that solves a common problem: not enough channels, one signal too many. Simple to place in a signal chain, and simple to trust since there’s no power supply to fail.
