Setting the Reference Level
 
You can set the reference level for the master volume output. By default the reference level is -20 dB, which means a tone of -20dB is displayed as -20dB. If you change the reference level to -10, a tone of -20dB is displayed as -10dB.
To set the reference level:
1. Click the pane menu button and select Set Reference Level.
The Reference Level dialog box is displayed.
2. Type a dB (decibel) level from -50 through -1.
3. Click OK.
