Q5i - Professional Class D Amplifier


Professional Class D Amplifier

The new developed Q series amplifier is the best power solution for professional sound system requiring maximum performance and portability. It is Beta Three evolutional integration of Class D amplification, switching power supply and DSP core in a rugged 2U chassis. With reliable extended power, light weight, smart signal display and advanced protection circuitry, Q series provides unmatched performance at real value. 


  • Housed in a rugged, all-steel 2U chassis.
  • Easy to configure in stereo / mono / bridge modes at the back
  • Switched mode power supply ensures an improved amplifier performance at high output levels
  • High efficient Class D amplification, low weight, low distortion and fast response.
  • Minimum load impedance (stereo / mono): 2Ω
  • Built-in DSP for the most flexible use in live sound or permanently installed sound
  • The simple front panel controls and a LCD screen give you all of your sound’s vital signs at a glance
  • Electronically balanced XLR inputs
  • Touch proof binding post and Speakon output
  • Variable fan speed is automatically adjusted by temperature with front to back air flow to keep amplifier cooling
  • Amplifier protection includes short circuit, overload, excessive temperature, DC on outputs
