KC Series

The KC series of amplifiers are suitable for any playing environment. The rugged frames and heavy duty speaker grills keep the speaker protected from impact when on the road. The KC amplifiers’ large range of ports allow you to connect your keyboard, microphone and phone. The loud volume outputs can reach comfortable gigging volume, whilst each model’s EQ settings let you tweak to your preference. This series has become the industry standard for musicians who need a reliable amplifier for any venue.

Road Ready Design

All KC amplifiers are built to be taken on the road. The outer frame is made of a thick, heavy duty material that can withstand bumps from being in transit. The drivers are protected using a thick, steel grill. This series’ controls are specifically designed to offer quick solutions to your live sound. The master volume control keeps your overall level appropriately compressed, whilst the individual level volumes allow you to balance each input yourself. No matter what venue, you can achieve the correct frequency balance by using the on-board equaliser. For over 20 years gigging musicians have trusted the KC series.
