9Test Mode and Level Adjustments

Test Tone

The test tone is used to calibrate the level settings of the speakers. A static noise will be heard cycling, in order, from the front left, center, right and both surround speakers. Using the remote control, adjust the Center and Surround levels until the volume of all the speakers is the same during the test. The test tone is used to calibrate the performance of the system. When listening to an actual recording, the volume level of the surround channels is generally much lower than that of the front channels. In fact, when listening to a movie, virtually all of the dialogue and a substantial number of effects are reproduced through the center channel.
