ZERO DBV TONES
Calibrated sine waves @ 0 dbv (1 Volt RMS)
Zero DBV Tones by Cristoforo Bonissone - Italy Zero DBV Tones is a calibrated 1 Volt audio signal recorded with a RME Firface soundcard. I've used a Rigol Calibrated oscilloscope to measure the XLR balanced line output, The sine was genterated by a calibrated Spectraplus application for Windows, for get a maximum quality signal. (https://www.spectraplus.com/) The picked up signal is a real 'cable loopback' made by a Fireface XLR output to Fireface XLR input, the cable is a XLR 'Reference Cable' made by ROLAND (RMC-GQ10 Gold). The input was measured with digital handhled calibrated multimeter (Agilent). All devices was calibrated by rispective productors during the earlier year. Use this application to setup any audio device with the correct input gain level. Checked by VirusTotal (https://www.virustotal.com) |
