Note It is not recommended to use VO preset level unless this is desired
globally for the VO. This is because each input bunch to the voice-
over is used to represent four input channels, whereas each output
bunch is used to represent two channels.
Test Mixfiles
The test mixfiles are useful during audio trouble-shooting and system
configuration. They should not be used when on-air.
test_eply.mix
This mixfile is designed to play the current Easyplay file out of the first eight
channels of embedded program outputs, preview outputs, and AES channels.
testtone_all.mix
This mixfile is designed to emit a 1 kHz sine wave onto all possible output
channels (program, preview and AES). There is no input source for this
mixfile.
Please note that the testtone will play out at 0 dBFS (+18 dBu) which is
considerably louder than normal program levels. To avoid damage to
loudspeakers it is advised to back them off a little before using this mixfile.
