These are solid, great-sounding boards that are durable, feature-rich and well-built; mature analog technology and knob-per-function usability make them particularly well-suited for education, house of worship, corporate, entertainment and other applications where multiple users with a wide range of skill sets can make full and immediate use of every function with little to no learning curve.
The GA24/12 provides 20 monaural and 2 stereo input modules in a compact, user-friendly knob-heavy analog desk. The Stereo Main outputs, 10 Mix Bus outputs, and two Matrix outputs support a wide range of applications; its 10 direct-access submixes and two Matrices make it well suited for FOH or Monitor applications in a variety of sound reinforcement settings. A separate ¼” balanced TRS Input B on each channel offers repro channel playback for recording applications as well.
• Each monaural input channel features a -26 dB pad, HPF, phase switch, 4-band EQ (HI-MID and LO-MID frequencies are variable), and 100mm long full-stroke fader.
• 48V Phantom power switching per group of four inputs.
• Four stereo AUX returns and TAPE IN jacks are provided as standard.
