Mix 2:1 Two-channel Summing mixer
Two-channel Audio Combiner & Mixer
The MIX 2:1? 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.
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
Combine two balanced mic or line-level signals
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 ?" 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.
MIX 2:1 Specifications
The MIX 2:1 uses a completely passive circuit that requires no power to operate and allows you to sum two signals together with minimal coloration or distortion. Either signal can be attenuated to create the desired blend between the two, or the level controls can be bypassed altogether, summing each input equally. The MIX 2:1 automatically compensates for the 6dB in voltage gain when summing two in-phase signals together, so you don’t overload the next device in your signal chain. Ground lift switches are provided to remove buzz and hum from ground loops, and the MIX 2:1 is housed in a rugged steel chassis to handle use in the studio and on the road.
