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.

Three stereo analog inputs feature individual volume controls to balance levels, and each can be sent to a shared effects loop to add reverb or delay in an instant using a dedicated footswitch. A USB connection allows laptop computers to be integrated into the setup for control of soft-synths, and a built-in sustain footswitch and connections for a stereo volume pedal provide additional ways to control your performance.\u003c\/p\u003e\n\u003ch2\u003eHigh headroom, low noise\u003c\/h2\u003e\n\u003cp\u003eA switch-mode power supply inside the Key-Largo elevates the rail voltage to 24 volts for extra headroom to handle the most dynamic digital keyboards and the hottest analog synths without fear of overload or distortion. This is paired with 24bit\/192kHz digital audio converters for high quality audio over USB when playing soft-synths or pre-recorded tracks. To eliminate noise when connecting multiple devices on stage, the main outputs are transformer-isolated to eliminate hum and buzz from ground loops, and all outputs are equipped with ground lift switches to further reduce noise.\u003c\/p\u003e\n\u003ch2 class=\"title-1 small bold left\"\u003e\n\u003cspan\u003eKey-Largo\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=\"1180\" src=\"https:\/\/www.radialeng.com\/wp-content\/uploads\/2018\/03\/key-largo-app-1-1.jpg\" class=\"img-fluid\" alt=\"\" decoding=\"async\" srcset=\"https:\/\/www.radialeng.com\/wp-content\/uploads\/2018\/03\/key-largo-app-1-1.jpg 2000w, https:\/\/www.radialeng.com\/wp-content\/uploads\/2018\/03\/key-largo-app-1-1-300x177.jpg 300w, https:\/\/www.radialeng.com\/wp-content\/uploads\/2018\/03\/key-largo-app-1-1-768x453.jpg 768w, https:\/\/www.radialeng.com\/wp-content\/uploads\/2018\/03\/key-largo-app-1-1-1024x604.jpg 1024w\" sizes=\"(max-width: 2000px) 100vw, 2000px\"\u003e\u003c\/div\u003e\n\u003cdiv class=\"app-desc\"\u003e\n\u003ch3\u003eManage a multi-keyboard setup with ease\u003c\/h3\u003e\n\u003cp\u003eThe Key-Largo effortlessly mixes multiple keyboard outputs down to a stereo feed for the PA system over XLRs.

A stereo aux send\/receive is available to feed rackmount reverbs and delays and effects pedals, or it can be used as an additional input for a fifth keyboard. MIDI and USB connections make it easy to control a laptop soft-synth, utilizing high quality 24bit\/192kHz digital audio converters.
