  • Owner's Manual
Power Meets Precision

The QS Series Amplifier delivers full-range sound with high efficiency, maximizing power without breaking the budget. Its regulated power supply ensures consistent performance at 80–90% efficiency, housed in a compact aluminum heatsink. The QS3000 1Ω offers 4 x 100 Watts TRUE RMS with digital Class D Brazilian technology, stable at 2 Ohms for versatile multi-speaker setups, all within a space-saving design measuring just 4″ × 5.40″ × 2″.

Maximum Power, Superior Sound

Experience doubled output with 2-channel bridged mode, delivering 2 x 200 Watts RMS at 4 Ohms per bridged channel. Enjoy wide frequency compatibility across subwoofers, midbass, midrange, full-range speakers, and tweeters, while the compact heatsink ensures precise midbass punch and crystal-clear highs. Advanced heat dissipation keeps the amplifier running cool, even under the most demanding playlists.

Versatile Power with Reliable Performance

The QS Series offers multiple options, including QS400.4, QS800.4, and QS1200.4 4-channel amplifiers, all tested for power accuracy at 100Hz–1kHz with THD ≤ 1%. Built for music applications, performance may vary slightly due to manufacturing tolerances. Enjoy peace of mind with a ONE (1) YEAR warranty covering defects in materials and workmanship under normal use.
