Stereo Mixing Keyboard Amplifier

The Ultimate Amplifier for Keyboards and Organ.

  • COSM

The Ultimate Amplifier for Keyboards and Organ.

The KC-1000 is our most powerful keyboard amp ever. This 5-channel tower uses DSP technology and a 310-watt/7-speaker system to accurately reproduce the full frequency range of organs, synthesizers and other electronic musical instruments. Onboard RSS and COSM effects create realistic tone cabinet reverberation when used with VK-Series organs, while unique ambient effects, split-frequency compression and 3-band EQ make the KC-1000 perfect for performance.

  • - Flagship keyboard amplifier with 310-watt output and 7-speaker design
  • - Four input channels available: Organ, Orchestral, Aux, Mic
  • - Ambient effect with RSS, split-frequency compression/limiting, 3-band EQ
  • - Organ input uses RSS and COSM for realistic tone cabinet reverberation
  • - Accurately reproduces the “Virtual Tone Wheel” sound of Roland VK-Series Combo Organs
  • - Stereo Link feature for chaining two KC-1000’s on stage

Revolutionary 7-Speaker Design

The KC-1000’s five-channel amplification system delivers 310 watts of power to fill virtually any space—from living rooms to small live venues—with rich, reverberant stereo sound. The secret is a radical new cabinet design using a total of seven speakers: two 1-inch tweeters, two 6.3-inch midrange speakers, two 6.3-inch side speakers and a 15-inch woofer. So now a single keyboard amplifier can cover the entire spectrum of sound from rich strings to deep pedal bass.

RSS and COSM Technology Inside

Created with organ players in mind, the KC-1000 features a dedicated Organ input for easy connection of Roland and Rodgers organs. This special input channel uses proprietary RSS and COSM technology to reproduce natural tone cabinet reverberation—essential to creating realistic organ sounds. In addition, the KC-1000 is the only keyboard amplifier designed to complement the Virtual Tone Wheel sound found in the VK-8 and VK-88 Combo Organs. Regardless of what type of organ you play, the KC-1000 will make it sound even better.

4-Channel Mixing with Ambient Effect

The KC-1000 features four input channels with built-in mixing capabilities, so you can connect anything from a VK-8 Combo Organ to a RD-700 Expandable Keyboard—even a microphone. And all of these input channels are processed with an exclusive Ambient effect using RSS technology, a split-frequency compressor/ limiter, and a three-band equalizer to bring your instruments to life.

Roadworthy Construction

Every aspect of the KC-1000—from its heavy-duty cabinet to the casters and individual knobs—was engineered to provide years of reliable operation. Whether you use the KC-1000 at home or on stage, this rugged keyboard amplifier can keep up with whatever demands you place on it.
