A client approached us who had a large number of amplifiers and speaker cabinets needed a speaker switch to allow him to patch any amp to any cabinet. He had done some research but the best offerings feel short of his requirements. The $389 Cabbone 1×4 from Tonebone (Radial Engineering) switches a single amp to two cabinets, or much more economical is the de Lisle 4×4 switcher at $289
Since neither of these came close we designed a 16×8 speaker selector. A single encoder knob with a push to select function in conjunction with an LCD display is all that is need to operate the device so making a very clean interface. It also includes built in dummy loads for tube type amplifiers and is housing in a 2U rack mount cabinet.
The switch matrix is expandable in blocks of 4×4 with a maximum of 16×8. Switching is performed using relays to ensure maximum signal fidelity.
