The GB2R from Soundcraft offers 16 mono inputs to a stereo mix output, a pair of full-feature stereo inputs, 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. 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.
