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.\u003c\/p\u003e\n\u003ch2\u003eCombine two balanced mic or line-level signals\u003c\/h2\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003ch2 class=\"title-1 small bold left\"\u003e\n\u003cspan\u003eMix 2:1\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003eApplications\u003c\/h2\u003e\n\u003cdiv class=\"slide-cards-wrapper equal\"\u003e\n\u003cdiv class=\"slide-cards-overflow app-slider\"\u003e\n\u003cdiv class=\"app-card\"\u003e\n\u003cdiv class=\"app-img slide-item\" data-slide=\"0\"\u003e\u003cimg width=\"2000\" height=\"1200\" src=\"https:\/\/www.radialeng.com\/wp-content\/uploads\/2018\/04\/mix-21-app-mix-preamps.jpg\" class=\"img-fluid\" alt=\"\" decoding=\"async\" srcset=\"https:\/\/www.radialeng.com\/wp-content\/uploads\/2018\/04\/mix-21-app-mix-preamps.jpg 2000w, https:\/\/www.radialeng.com\/wp-content\/uploads\/2018\/04\/mix-21-app-mix-preamps-300x180.jpg 300w, https:\/\/www.radialeng.com\/wp-content\/uploads\/2018\/04\/mix-21-app-mix-preamps-768x461.jpg 768w, https:\/\/www.radialeng.com\/wp-content\/uploads\/2018\/04\/mix-21-app-mix-preamps-1024x614.jpg 1024w\" sizes=\"(max-width: 2000px) 100vw, 2000px\"\u003e\u003c\/div\u003e\n\u003cdiv class=\"app-desc\"\u003e\n\u003ch3\u003eMix the output of two mic preamps to a single track\u003c\/h3\u003e\n\u003cp\u003eCombine two tracks to a single input on your audio interface.
