Cadence QRS Series Amplifiers

City of Industry, CA. 07/01/2017, Cadence is proud to introduce its new line of Class GH amplifiers.

The all new QRS Series of amplifiers from Cadence bring back Sound Quality and Dynamics in one package with a Class G/H design. Class G/H amplifiers offer the best of all possible characteristics. Power output, distortion, efficiency, heat, noise, and size are all class leading specs with this design.  Why does this type of amplifier perform so well? It’s built for sound quality, not test tones or SPL burps. Class G/H works with the dynamics of the music, not against it. When an amplifier is playing music even at full volume, due to its dynamic nature, it is working at 1/2 power about 100% of the time, not utilizing full power until a strong passage like the impact of drums or deep bass notes need it.

Fully protected from all types of faults with Microprocessor Real-Time Monitoring, which includes short circuit, low voltage, over voltage, low impedance protection, thermal protection, and thermal rollback. The QRS Series also features a sleek new chassis design with the custom engraved logo and LED Cadence “wings”. The new modern, elegant design, high performance, full features and very attractive price points will make the QRS amplifiers the “go to” amps for Cadence Dealers worldwide.

The QRS Series will consist of 9 models:

  • 180GH: 180 Watts x 2 @ 4 OHM RMS
  • 300GH: 300 Watts X2 @ 4 OHM RMS
