RTA
The 31-band RTA (Real-Time Analyzer) allows you to monitor the sound system’s frequency response. A bulit-in signal
generator is also available in the RTA menu. The signal generator and RTA can be used to manually fine-tune and troubleshoot
the system or to help identify system feedback and resonant frequencies. Since the signal generator can be steered to each of
the direct inputs, it can also be used to verify signal routing in a preset configuration.
The following section provides a description of each of the RTA parameters and how to edit them.
To access and use the RTA and signal generator:
1. Press the RTA button.
2. Use the SELECT wheel and UP/
DOWN buttons to navigate the
menu and edit parameters.
