The LAB.GRUPPEN C28:4 is a robust 4‑channel installation amplifier delivering up to 700 W per channel at 4 ohms in a compact 2U chassis. Its proven Class‑TD topology pairs the sonic quality of Class‑A/B with the efficiency of Class‑D, while the regulated switch mode power supply (R.SMPS) ensures consistent output under demanding loads. Flexible configuration includes selectable gain, scalable Voltage Peak Limiter (VPL), and bridge‑mode operation, with support for low‑impedance and high‑impedance 70 V/100 V distributed systems. NomadLink networking enables monitoring and control via intuitive DeviceControl software, streamlining large‑scale installations. Comprehensive protection covers current, voltage, DC, temperature, short circuit and open load conditions for dependable operation. Practical install features include four balanced analogue inputs on 3‑pin Phoenix connectors, four 2‑pole screw terminal outputs, efficient front‑to‑rear cooling with a copper heat‑sink design, and a removable dust filter to maintain airflow and performance over time. Housed in a durable 2U rackmount chassis, the C28:4 is engineered for reliability and ease of integration. Ideal for performance venues, houses of worship, corporate AV, and distributed audio systems requiring clean power and rock‑solid control.
