Test Tones
Test Tones – Multiple setup tones are available to calibrate the AERO.qc and other
downstream equipment. The Level control is self-explanatory, and is set at the standard –
20 dBFS reference level and adjusts the overall level of the test signals. On/Off turns the
selected test signal on or off while Cycle determines which channels will reproduce the
selected test signal. It can be adjusted to cycle through all channels, all channels of just the
main program (default), and individual channels.The available test signals are:
•
Sine – 1 kHz sine wave
•
Voice – Voice ID of all selected channels
•
Pink Noise – Equal energy-per-octave noise
•
White Noise – Equal level-per-octave noise
•
Brown Noise – Low-pass-filtered noise
•
Brown Nose – Try it (because broadcast audio is a funny business)
•
BLITS – Black and Lane Identification Test Signal (multichannel identification tones)
