This Soundcraft GB2R 12.2 mixer offers 12 mono inputs, 2 full-feature stereo inputs, and 2 group busses, and 6 auxiliary sends. It’s a 19”, rack-mountable mixer intended for smaller-scale installations including houses of worship, performance venues, portable PA systems, and broadcasting studios.
The difference between the two GB2R models is the inputs and outputs. This 12.2 model offers stereo inputs for both Mic and Line. Mic signals can be routed to the local channel while the Line inputs are available as stereo returns on the main mix bus. Enjoy up to 26 inputs in a more compact build using the 12.2’s pair of stereo returns and a 2-track input. Every input boasts a pre/post switchable direct output so you can interconnect recording or effects gear.
The GB2R also features a GB30 Mic Preamplifier and Equalizer that enables high-resolution adjustment over a wide gain range of 55 dB. An internal universal voltage PSU dispenses with the need for power supply connections. Compact and easy to integrate into setups of myriad sizes, shapes, and styles, this mixer offers a connector section in a rotatable pod so you can gain cable access to the top of the mixer or the rear—perfect for positioning on a table or desktop or mounting it in a 19” rack.
