  • Mix Two Channels to a Single Mono Output
  • Individual Level Controls
  • Balanced 1/4″ TRS and XLR Inputs
  • Completely Passive, No Need for Power


The Radial MIX 2:1 Two Channel Audio Combiner and Mixer is a simple yet highly useful mixer that passively sums two audio channels down to one. This enables you to easily sum the stereo outputs of a console, recording interface, or portable playback device down to mono, or to mix any two signals together and balance their relative input levels.

The MIX 2:1 makes it easy to sum together any two signals, whether it's two microphones on a single guitar amplifier, or the stereo line outputs of a mixing console. At the inputs of the MIX 2:1, both ¼" TRS and XLR connectors are available, with ground lift switches to eliminate buzz and hum from ground loops and ensure noise-free operation. A trim control is also featured on each input, so if you are connecting two separate mono sources such as the outputs of two mic preamps, they can each be attenuated as needed to match their levels at the output. After both signals are passively summed together, they feed a single XLR output that can be connected to a powered speaker, or the input of a console or recording interface.

Key Features:

  • Mix two channels to a single mono output
  • Individual level controls can be bypassed when not in use
  • Balanced 1/4″ TRS and XLR inputs
  • Completely passive, no need for power
