1800i Signature

The 1800i Signature is a two-input, four-output Digital Signal Processor (DSP) intended for use in active loudspeakers for professional audio or high-end home audio.

SKU: Z07310
The 1800i is a two input, four output Digital Signal Processor (DSP) intended for use in active loudspeakers for professional audio or high end home audio. Available in four performance levels and using only the best sounding components available, its unrivalled audio quality and feature set match the highest standards.

All connections on 1800i are internal multi-pin connectors. To build a full product, additional PCBs are needed with external connectors. See “Accessories” for details.
