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.
