KA-1100

Maximise Performance

The KA-1100 subwoofer amplifier was designed in-house from the ground up. This dual-mono subwoofer amplifier offers pre-configured DSP modes that are optimised to drive and maximise the performance of Krix passive subwoofers, ensuring movie soundtracks play with high output and incredibly low distortion.

DSP modes are set for Krix MX-5, MX-10, Cyclonix 11 and Cyclonix 12 subwoofers. Each mode is specifically tailored to accurately amplify the input signal to full power without compression or loss of dynamics. A third pre-set mode is for general subwoofer use. If an input signal is applied beyond the subwoofer maximum capacity, soft limiting will minimise distortion and protect the loudspeaker driver.

The KA-1100 is based on Class D amplification from ICEpower™ and includes a Krix custom-designed 24-bit signal processor board. Engineered with home cinema enthusiasts in mind, the amplifier features a fan-less design for ultra-quiet operation, 12V trigger for easy power-on and both balanced and unbalanced connection options.

The sleek and modern design allows the unit to blend in with any furniture and cabinetry, or stylishly sit amongst other electronic equipment within a rack (rack ears are included). The brushed aluminium fascia can be easily removed for access to all controls.

For the ultimate sound experience at home, play it through Krix.

Signal Processor

The KA-1100 incorporates a custom 24‑bit signal processor board designed and developed by Krix to maximise the performance from your Krix subwoofer. It includes three user selectable modes that optimise high pass filter and limiter settings to suit Krix MX-5, MX-10, Cyclonix 11 and Cyclonix 12 subwoofers.

Limiter settings are specifically tailored to accurately amplify the input signal to full power without compression or loss of dynamics. If an input signal is applied beyond the subwoofer maximum capacity, soft limiting will minimise distortion and protect the loudspeaker drivers from damage. The KA-1100 features limit LEDs for each channel to indicate when the output is being limited, protecting the subwoofer.

ICEpower® Amplification

The KA-1100 is based on a Class D amplifier module from ICE power®. These amplifiers are a high efficiency design and therefore generate far less heat than conventional Class AB amplifiers. As such, fan cooling is not needed, minimising power consumption and making it completely silent when in operation.

A high-current, switch-mode power supply ensures full power can be delivered for sustained periods, producing maximum dynamics and impact from your subwoofers.
