JAM Systems Q10 :: 4 x 2500W amplifier

The JAM Systems Q10 is a high-performance professional switch-mode power amplifier delivering exceptional output from a compact 1U chassis. Designed for demanding touring, installation, and high-output subwoofer applications, it combines high power density, low weight, and robust real-world reliability.


  • Compact 1U design weighing just over 10 kg for reduced rack weight and easier handling
  • Fully modular four-channel architecture with a dedicated switched-mode power supply per channel
  • Consistent output and stability whether one channel is driven or all four simultaneously
  • Zero crosstalk between channels thanks to fully independent power stages
  • High-efficiency PWM output stage with high switching frequency and optimised dead-time for low distortion
  • High overall efficiency with reduced heat generation and improved thermal performance
  • Comprehensive protection systems for dependable operation under demanding conditions
  • Recessed stepped attenuators for accurate, repeatable gain matching

Per-channel power output : Power figures from independent laboratory testing under controlled conditions.

  • 2500 W into 2 ohms (EIAJ 8:32 burst, 1 kHz, 1% THD)
  • 2350 W into 4 ohms (1 kHz continuous) 1% THD
  • 2275 W into 4 ohms (100 Hz continuous) 1% THD
  • 1250 W into 8 ohms (1 kHz continuous) 1% THD
  • 1200 W into 8 ohms (100 Hz continuous) 1% THD

Power ratings note: EIAJ figures represent short-term burst power using signals with typical musical crest factor. Continuous low-frequency operation into low impedances will invoke current limiting as part of the amplifier’s protection system, with sustained clipping (>2 s) triggering automatic protection. During extended continuous tests (>10s), 2 ohm output is limited to a level similar to 8 ohm operation. With high crest-factor programme material, 2 ohm burst output is typically around 10% higher than 4 ohm, reflecting real-world music performance rather than continuous test conditions.
