The DQ series professional power amplifiers by JL Audio mark a new milestone for Class D power amplifiers. Equipped with advanced Class D amplifier modules and high-efficiency SMPS power supply modules, the DQ series delivers exceptional efficiency, reliability and power density. It can output unprecedented high power within a standard cabinet that is just 1U in height and 9 inches in depth.

1. In terms of structure, it features a standard 19-inch rack width and a 1U×9-inch cabinet design. It is compact, lightweight and easy to install.

2. It adopts stable and efficient Class D amplifier modules with an efficiency of over 92%. This endows the DQ series power amplifiers with outstanding efficiency, reliability and superior power density.

3. The device is powered by a high-efficiency and stable R-SMPS power supply system integrated with an Active Power Factor Correction (PFC) circuit. The PFC enhances the reliability and controllability of the DQ series amplifiers. It can adjust the current waveform according to the AC voltage waveform, support global wide voltage operation ranging from 90V to 264V, and allow a single standard circuit breaker to carry higher power.

4. A comprehensive protection system effectively prevents damage caused by improper operation and further improves equipment reliability.

5. It is fitted with high-efficiency and stable Class D amplifier modules, high-efficiency and stable R-SMPS power supply system, and an efficient speaker back EMF absorption system.

6. It is equipped with a unique peak limiter and ripple elimination network.

7. The whole unit features an extremely light weight and minimal space occupation.

**Application Scenarioses**

1. Sound reinforcement applications requiring high power density and premium sound quality

2. Installation for KTVs, large and medium-sized bars, cafes and lounges

3. PA system applications for portable use and rental industries
