OVERVIEW
The LINUS-V1804 is a four-channel touring-grade power amplifier developed using CODA Audio’s latest amplifier topology. In a compact 2U enclosure, it combines high output capability with very low distortion characteristics for professional sound reinforcement applications.
The V1804 delivers 3000 W per channel into a minimum 4 ohm load, providing sufficient power for demanding portable and small touring systems. Its output capability, sonic accuracy and system flexibility allow it to drive any CODA loudspeaker up to APS-Pro.
The amplifier features a new DSP architecture, enabling future firmware updates and long-term system adaptability. Dual high-efficiency SMPS with PFC support universal 100–240 V mains operation.
Analogue and LiNET inputs are standard, with Dante available on the V1804-D model.
Integrated loudspeaker presets—excluding sensor-controlled subwoofers and large-format line arrays—are stored onboard and accessed through the 320 × 240 pixel touchscreen.
Amplifier control is available via the LINUS Control App, or through networked operation using LINUS Control Software for complete system management.
Designed for professional touring environments, the LINUS-V1804 is backed by a five-year guarantee. Firmware updates ensure the amplifier remains current with new presets and specialist functionality.
Power that punches above its size. Control that fits in your pocket.
