Dual-mode operation provides flexibility: engage PBTL mode for full-frequency mono amplification of passive speakers, or switch to SUB mode for dedicated subwoofer control with integrated 20-300Hz low-pass filtering and adjustable crossover frequency. The compact aluminum chassis houses efficient Class D circuitry optimized for transparent bass reproduction and minimal distortion. Ideal for audiophiles seeking versatile mono amplification in a space-conscious form factor.
