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.
KEY FEATURES
• 2 or 4 inputs (selectable), 4 outputs
• MILAN or AES/EBU input
• 96kHz sample rate (48kHz in 4-input mode)
• Unparalleled audio quality
• State-of-the-art digital processing
• Programmable User Interface
• Monitoring and permanent logging of key parameters such as temperature, signal level and gain reduction
• 600 FIR taps per output
• 250 presets
• Optional Dante and AES67 module available
• Multiple display and GPI / GPO support
• Optional Tilt Sensor
• 2 DC inputs for potentiometers
• Optional 4 current measurement AC inputs
• 2 temperature sensor inputs
• 100Mbit LAN
• Plug-and-Play compatibility with Pascal, Powersoft, ICEpower and Hypex amplifier modules
