Analog Input to Analog
Output Gain Accuracy
Over Frequency
This test measures the Analog Audio Output level accuracy over the audio
frequency range, when using an Analog Input as the audio source.
Typical Operation Check. This test checks for typical operation. Typical values
are not guaranteed characteristics and are listed in the test record as Pass / fail.
1. Press FACTORY.
2. Press CONFIG to display the CONFIG menu.
