Testermeter- H233 Industrial quality control Audio Power Amplifier
Product name: Power amplifier Product model: H233 The H233 audio power amplifier is a professional equipment specifically used for measuring building sound insulation, material sound insulation, and exterior wall sound insulation. The H233 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 50121 Standard for assessment of building sound insulation GB 50118 Code for Design of Sound Insulation in Civil Building Functional Characteristics |
Dual Channel Output
The H233 audio power amplifier has dual channel output and can simultaneously connect two undirected sound sources for measurement. Internal and external sound source input There are two ways to input sound sources, internal and external, to meet various scenarios. Wireless Remote Control Our power amplifier adopts a 433 MHz remote control, which has strong wall piercing ability and can remotely control up to 200 meters in a free field. Lightweight Housing The excellent structural design not only ensures the equipment is sturdy and reliable, but also achieves lightweight, convenient transportation and portability. |
