LB Series Tracking Class-D Power Amplifier

Class-A sound quality with Class-H efficiency — 300W to 2300W per channel, 2U

Tracking Class-D2U7 models300W–2300W/ch

T-D (Tracking Class-D) design combines Class-A sonic quality with Class-H efficiency, power and low heat
Power utilisation above 95%, output efficiency above 91% — minimal heat under continuous full load
DC protection, relay soft-start, clipping limiter, short-circuit, over-heat, over-current and open-circuit protection keep speakers safe
JRC5532D input stage, 50V/µs slew rate, no self-oscillation — fast, clean transient response
Amplifier devices pressed directly onto waved copper heatsinks for zero-gap heat transfer; 30% better than aluminium
2.0mm steel chassis, 2.5mm aluminium panel — built for touring racks and fixed installs alike

91%+Output efficiency — low heat, all-night shows
