GX9000 User manual Rev 2.1 Metering and the Display PPM Scale Display .FinePPM Normal -22dB +/-1 -20dB +/-1 -18dB +/-1 -16dB +/-1 Frames on/off Display .Frames Off On You can expand the PPM scale to cover just 2dB from the top to the bottom, for the purposes of calibration of internal and external ADC’s. The centre pixel can be programmed to represent either –16dBFS, -18dBFS, -20dBFS or -22dBFS. In Expand mode two pixels light for each PPM column until the incoming level is aligned. One pixel shows the incoming level and the centre pixel flashes until the incoming level matches the alignment level. If the incoming level is outside of the expanded range, the bottom or top pixel stays lit to indicate the direction of the error. Expand mode can be cancelled by selecting Normal. • Press the Setup button. • Use the Rotary Wheel and Parameter Up and Parameter Down buttons to select the Display | .FinePPM menu heading. • Press the Value Up and Value Down buttons to select one of the four scales. • Press the Enter button to enter Fine PPM mode. This heading allows the user to not display the frames segment of the Timecode display. Some users prefer to not display these characters to make the timecode more readable. Genex Audio Inc Page 60
