Description: UPATED DESIGN: This is a blank PCB plus front and rear case panels to build a "Sound Card Interface / AC RMS Voltmeter". This is a device that connects to your PC sound card, and (used with available FFT and other audio analysis software) enables it to be used as a high-quality audio test system. For full details on the design, including pictures, measurements, schematics, bill of materials, etc. refer to my web site. eBay will not allow me to post the link here any longer, so you will need to do a web search. The interface performs a number of functions, including: Provides a high impedance (100k ohms), floating input to connect to the device under test (audio amp, etc.) Protects your sound card input from excessive voltage (up to 200VAC & 400VDC!) Allows scaling or amplifying the input, from 200mV to 200V full-scale Amplifies and buffers the sound card output to use as a source (both balanced and unbalanced) Provides an accurate AC RMS voltmeter This auction is for is the PCB, front, and rear panels only, nothing else is included.
