1800B

The 1800B 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: Z01941
The 1800B is a fully integrated two input, four output Digital Signal Processor (DSP) intended for use in active loudspeakers for professional audio or high end home audio. Available in two performance levels and using only the best sounding components available, its unrivalled audio quality and feature set match the highest standards.

The 1800B is set up to be directly mounted to the rear panel of a loudspeaker. To connect to an amplifier module, a range of interface options is available for various models. See “Accessories” for details.

By setting a solder jumper, 1800B can be used with two analog inputs, or with one input and one link out.
