Vehicle Sound for Pedestrians Amplifier Board (VSP)
Product Use
This Vehicle Sound for Pedestrians Amplifier Board Module (VSP) is especially developed for Automotive use.
This Amplifier Board satisfies all the requirements of Federal Motor Vehicle Safety Standard No. 141, Minimum Sound Requirements for Hybrid and Electric Vehicles.
The class-D Stereo Amplifier IC requires 10 VDC to 30 VDC power.
The VSP Amplifier Board uses the custom IC (MRXVSP2D).
The VSP Amplifier Board fully satisfies all the requirements of FMVSS#141.
Precision operation is assured by in IC oscillator.
Vcc Power Input Pin is connected to nominal +12 VDC that has a Common Ground with the IC sound Input and Output as well as Control lines.
The two Digital Control Inputs control the four distinct dB levels of the D Class amplifier gain, as if required by the FMVSS #141.
