PTM series

PTM1323 is a 2.1 channel power amplifier designed specifically for Party K speaker systems. Adopting R-SMPS+Class I™ technology, provides a maximum of 2* 2500W@2.7Ω + 1*3900W@4Ω huge power output in a 2U height standard chassis, which is easily to drive 4pcs 15″ full range speakers and 2pcs dual 18″ subwoofers. In extreme cases, it can drive 8pcs 15 “full range speakers and 3pcs dual 18” subwoofers. With the efforts, we create a high-performance and high cost-effective Party K audio system, while reducing unnecessary connecting cables of power amplifiers, making the system more concise with higher performance.
