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.
Dolby Pro Logic, Hall and Concert Modes
1. Push the Test button on the remote control.
2. When the test tone is heard from the center speaker, push the +
or – Ctr/Rear Level button to match the volume of the center
channel to the front left and right channels.
3. When the test tone is heard from the surround speakers, push
the + or – Ctr/Rear Level button to match the volume of the
rear channels to the front.
6-Channel Input
1. Push the Test button on the remote control. The test tone
will cycle through all channels.
2. When the test tone is heard from the center speaker,
push the + or – Ctr/Rear Level button to match the volume
of the center channel to the front left and right channels.
3. When the test tone is heard from one of the surround
speakers, push the + or – Ctr/Rear Level button to match
the volume of that surround speaker to the front, left and
right channels.
4. Repeat step (3) when the test tone is heard from the other
surround speaker.
Please note that the 6-channel direct input mode has its own
level settings that are independent of the other modes.
