audio, sound, power
A power amplifier designed to power sound sources in building and room acoustic field measurements.
Compact, lightweight and built into a robust flight case, the power amplifier is easy and safe to carry to the measurement location. All connectors and controls are on the front for easy access, and the amplifier can stand horizontally or vertically as required for convenient operation.
With its calibrated controls and level indicator lamps, getting the output level right and reproducing previous settings is simple. For flexibility, the amplifier has XLR, jack and BNC input sockets. A sensitivity selector in 10 dB steps adapts the amplifier to a variety of source-signal levels and sound sources. Maximum output power is 500 W with a frequency response of 20 Hz – 20000 Hz within ± 1 dB.
