Soundcraft GB2R-12.2 - 12-Channel Rackmount Analog Mixing Console with 2 Stereo Inputs and 10 Busses in Dark Blue Finish

The Soundcraft GB2R-12.2 is a professional-grade, rackmountable 12-channel analog mixing console designed for smaller installations in churches, performance venues, broadcast environments, or portable PA systems. With its compact 19-inch frame, this console offers a remarkable blend of high-quality sound performance, versatility, and ease of use, making it ideal for both fixed installations and on-the-go setups. Featuring 12 mono inputs and 2 full-feature stereo inputs, the GB2R-12.2 provides a wide range of connectivity and functionality, all within a durable, space-saving design.

One of the standout features of the GB2R-12.2 is its use of Soundcraft's renowned GB30 mic preamp and precision EQ design, which deliver exceptional audio clarity and transparency across all input channels. The GB30 mic preamps provide up to +22dB of headroom, ensuring distortion-free performance, even under demanding conditions. Each input channel includes a 3-band EQ with a sweepable mid-range for precise tonal control, along with a high-pass filter at 100Hz to eliminate unwanted low-frequency noise. Phantom power is available on all mic inputs, making the GB2R-12.2 compatible with a wide variety of condenser microphones.

The GB2R-12.2 offers a flexible range of routing and mixing options with its 10-bus architecture, which includes a stereo sub-group, mix outputs, and a mono sum output. Each input channel features a direct output, providing seamless integration with multi-track recording systems or external effects processors. The direct outputs can be switched pre or post-fader, offering users additional control over their signal flow. The console's six auxiliary sends provide ample flexibility for creating custom monitor mixes, effects sends, or routing audio to external devices.

To enhance its usability in various setups, the GB2R-12.2 features a rotatable connector pod, allowing for top or rear cable entry, depending on whether the console is rack-mounted or placed on a table. This clever design minimizes cable clutter and optimizes workspace organization. The console also includes 100mm high-quality faders, which provide smooth and accurate level control, along with intuitive solo and mute functions on each channel. Comprehensive metering is provided through 12-segment tri-color LED bargraphs, ensuring accurate monitoring of signal levels at all times.

The stereo inputs on the GB2R-12.2 are equipped with both mic and line connectors, offering additional versatility. When mic inputs are used on the stereo channels, the line inputs act as stereo returns routed to the main mix bus, enabling up to 26 inputs to be mixed in this compact console. For added convenience, two stereo returns and a dedicated 2-track input are available, perfect for connecting playback devices such as CD players or digital audio sources.

With its rugged construction, high-quality components, and comprehensive feature set, the Soundcraft GB2R-12.2 is built to withstand the demands of both live and studio environments. Its compact design, combined with the precision of Soundcraft engineering, makes it an excellent choice for any situation where space is at a premium, but performance and reliability cannot be compromised.
