JBL ESC550 setup guide Test Tone, Balance, Center Channel Volume

Test Tone

For proper Dolby Pro Logic operation, a test tone is used to calibrate the volume set- tings of the speakers. A noise will be heard cycling, in order, from the front left, center, right, and both surround speakers.

Tone Calibrate

Using the remote control, push “Tone.” Then adjust the Center and Surround levels until the volume of all the speakers is the same during the test. Note: 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 sub- stantial number of the effects are reproduced through the center channel.
