Motion Sound KBRM Twin Mono Amp With PRO3T Speaker

Product Description

The sound of the organ is back in style. There are those who say it never left, but this is a grand time for the king of instruments. The synth guys have done a great job at making basic organ sounds, and there are a few incredible dedicated organ keyboards and modules. But reproducing the grinding sound of the rotating speaker has been a different kettle of fish entirely. All the digital multi-effects boxes boast rotary simulations, but they only hint at the real thing. Until recently, if you wanted the authentic vintage sound of rotating speakers, it meant dealing with dodgy electronics, fat cables, and big wooden boxes that weigh a ton. And you'll pay a premium price for that misery if you go the vintage route.

Motion Sound thought about this and found an answer. The vintage boxes had 2 elements, a "bass" rotor and a spinning horn, an internal crossover sent the proper frequencies to the proper elements, and voila, that unmistakable sound. Motion Sound learned that the bass rotor can be digitally simulated quite well, but nothing can take the place of the horn. So they built a box called the PRO3R, which was a spinning horn by itself and took the keyboard world by storm. It sounded like the real thing, was easy to hook up and carry, and was priced affordably. But you still had to have an amp to hear the digital bass rotor, not to mention the other keyboards that didn't have to go through the rotary system.

The KBRM is an integrated keyboard amp with 100 watts of power going into a 12 in. speaker and a 4 x 4 dynamic horn. And mounted in the top of the surprisingly small and lightweight cabinet is a full blown PRO3R spinning horn! An innovative 3-channel mixer is also included onboard.

The first channel is the "Rotary channel." A real 12AX7 tube preamp makes the tone warm, and the pre and post gain controls let you add the right amount of tube crunch to the signal. A tonal contour dial lets you adjust the overall characteristics from mellow vintage to sharp modern sounds, and you can modify the low rotor simulator's level and effect depth. A provided footswitch with a blissfully long cord lets you choose between fast, slow, and stop. And YES it does speed up and slow down in the vintage way. Don't worry about miking up the rotor, because a mic is already built in, and the signal goes out the XLR jack in the back, combined with whatever else you have plugged in the front of the mixer.

The second channel is labeled "Channel One," and it can be used for a keyboard that doesn't need the rotor, or it can be used for a monitor signal from a PA board. A switch disengages this channel from the XLR connector on the back. The third or "Channel Two" input sends the signal through level, treble, and bass controls, and through the amp and speakers and XLR jack in the back.

The cabinet is fashioned in a way to lean back like a monitor, if so desired, or it can sit straight up.

Anybody who plays organ or organ samples needs this rig, guitarists who are looking for a new sound (although it's been used for years) can also use it. Electronic accordion players, this is for you, too! It's the best alternative to the big wooden box yet, and beats the pants off of the digital simulators. This product is USA designed and built, just like the vintage. zZounds is an authorized dealer of Motion Sound products.
