Audio Power Amplifier

Product name: Power amplifier

Product model: SVLab 233

Manufacturer brand: SVLab

The SVLab 233 audio power amplifier is a professional equipment specifically used for measuring building sound insulation, material sound insulation, and exterior wall sound insulation.

The SVLab 233 power amplifier is equipped with built-in white noise and pink noise generators, and supports external sound source input. In addition, it can also receive dual channel outputs from two undirected sound sources simultaneously.

Our power amplifier is also equipped with a distance wireless remote control, which can be used for wireless control across multiple floors in the sound insulation measurement laboratory.

Standards

  • GB/T 19889 Acoustics - Measurement of Sound Insulation in Buildings and Building Components
  • GB 50118 Code for Design of Sound Insulation in Civil Building
  • GB 50121 Standard for assessment of building sound insulation
 

Functional Characteristics
