Real rotary horn channels and stereo/Hi Fidelity channels. Plug an organ into the rotary horn channel, and a Keyboard or sound module into the Stereo/Hi-Fidelity channel and get both sounds at the same time from one amplifier!

The KBR-3D's real rotary horn channel with stereo low rotor simulator completes the sound of your digital Organ, the rotary sound you have been searching for. The 3D stereo inputs will amplify a synthesizer, electronic piano, or sound module in incredible true expanded stereo, the way the manufacturer intended. Use both channels simultaneously-- a true dual sound amplifier in one cabinet!

Real rotary horn, 800 Hz crossover, low rotor simulator for organ, and 3D Hi-Fi stereo for keyboards in one amplifier!

The KBR-3D's rotary horn channel features a 12AX7 tube and accepts two Organ sound sources. The stereo 3D channel features a spatial expander and accepts two stereo sound sources.

Comments about Motion Sound KBR-3D Twin Keyboard Amp:

This is my 2nd KBR-3D, and my 4th Motion Sound product. The concept is great: an amp that will accept two (even 3) keyboards and give one board a true rotary channel. In that respect, it is supurb. Absolutely tremendous. Where it falls short is the volume output. The claimed 240 watt rating is SIMPLY NOT THERE. I also have a Peavey KB300BW with a claimed 160 watts, and two of these KBR-3D's could not match one Peavey. The build quality is no better or worse than other amps I've owned. The 3D expander channel is fantastic, it makes anything you put through it sound lush and full. The overall sound of the amp, both rotary and stationary channels, is acceptable, it just needs more power. The XLR outputs on the back that mix everything down for p.a. applications have been bad mouthed by every sound tech that has used them, for live performances this amp must be miked, and it takes 4 (YES!) to mic this amp properly, exactly like a real Leslie. Just putting 1 or 2 mikes in front of it and hoping that you get it all won't work. With 2 people lifting the amp by the handles, it will want to roll forward on you, it's top heavy. The angled cabinet makes stereo separation really nice sounding, but there's no subwoofer output, and there's a hiss at moderate to high knob settings. The concept is there, it just needs more honest power and the bugs worked out.
