This 19" rack-mountable mixer is designed specifically for smaller installations in churches and performance venues, or for small portable PA systems. It will also find friends in broadcast where its high quality and feature set will be very appealing.

The GB2R model is available in a 16 channel configuration and this 12+2 channel configuration. This 12+2 model of the GB2R offers 12 mono inputs, two full-feature stereo inputs and 2 group busses. Both models have 6 auxiliary sends.

As with all Soundcraft consoles, emphasis was placed on operational simplicity, clear and intuitive layout and the highest possible audio performance. The Soundcraft GB2R inherits both the GB30 Mic preamplifier and GB30 Equaliser designs from the GB4 and GB8.

For ease of installation, the connector section is contained in a rotatable pod, allowing cable access from the top of the mixer if sat on a table-top, or from the rear when mounted in a 19" rack.

On the stereo inputs on this 12+2 model, connectors are provided for both Mic and Line inputs. With Mic signals routed to the local channel, the Line inputs are available as stereo returns to the main mix bus. Two stereo returns and a 2-track (for example CD replay) input are provided, which means that the GB2R-12+2 model can offer up to 26 inputs to mix in a mixer just 19" (485mm) wide.

Every input has a pre/post switchable direct output for recording or effects sends, while an internal universal voltage PSU avoids external power supply connections.
