The document describes the features and characteristics of a power amplifier product called fP 3400, including power output, compact design, lightweight, unique power matching function, multiple positions gain switch, efficient cooling system, improved low-end power bandwidth, etc.
The Lab.gruppen fP 3400 is a lightweight and space-saving power amplifier designed for high-quality touring sound systems and demanding permanent installations. It utilizes the company's patented Class TD technology, which combines the efficiency of Class D amplifiers with the sonic quality of traditional Class AB designs by avoiding the need for a recovery filter.
Key features include a regulated switch-mode power supply capable of handling significant variations in mains voltage, an Intercooler cooling system, and multiple gain positions selectable via DIP switches. The unit offers bridged mono outputs, sophisticated protection circuitry against DC, VHF, thermal, AC, and clipping issues, and front-to-rear airflow with accessible dust filters.
