System Configuration
Speaker Output Adjustments Adjustments and calibration of the speaker output levels is important to proper surround operation. During this process, the unit is adjusted so that the output levels from each channel is set so that all channels have a reference level that is as close to one another as possible. A small amount of time spent to properly calibrate the AVR55�s output levels will enable the unit to deliver all the performance it is capable of within the environment of your specific listening room. IMPORTANT NOTE: Many listeners are often confused about the operation of the rear (surround) channels. While some assume that sound should always be coming from each speaker, most of the time there will be little or no sound in the surround channels. This is because they are only used when a movie director or sound mixer specifically places sound there to create ambiance, an effect or to continue action from the front of the room to the rear. When the output levels are properly set it is normal for rear/ surround speakers to operate only occasionally. Artificially increasing the volume to the rear speakers may destroy the illusion of an enveloping sound field that duplicates the way you hear sound in a movie theater or concert hall.
Before beginning the adjustment process make certain that all speaker connections have be properly made. The system volume should be set to the level that you will use during a typical listening session. Finally, make certain that the is set to the center Balance Control � �12 O�clock� position. 1. Press the Test Tone button k on the remote to begin the adjustment process. A test noise will circulate from one speaker channel to the next, as indicated in the Information Display F. 2. Take a minute to listen to the test noise from each speaker as the location indicated in the display changes. Check to make certain that, for example, when the display reads TEST-FRONT L, that the test noise is coming from the front left speaker. If the test tone�s location does not match the display for any channel, press the Test Tone button k to end the adjustment and turn the unit off using the Main Power Switch 1. Check all connections to maker certain the Speaker Outputs � are connected to the proper speaker. Installation Hint: While the test tone is circulating among the channels, make a note if it sounds reasonably equal in volume, or if one channel or more channels seems significantly louder than the others.
3. When you have verified that all channels are properly connected, press the Channel Select button l to begin the adjustment process. 4. The Test Tone will stop circulating and be heard through the center channel only. If the center channel appeared to be at a level above or below the front left/right channels while the tone was circulating, press the Speaker Level Adjust buttons m to raise or lower the volume so that the tone is the same level as the other channels. When the adjustment is complete, press the Channel Select button l to move to the next channel. 5. The Test Tone will now be heard through the right surround speaker. As with the center channel speaker, use the Speaker Level Adjust buttons m to adjust the level as required so that the tone is the same level as the other channels. When the adjustment is complete, press the Channel Select button l to move to the next channel. 6. The Test Tone will now be heard through the left surround speaker. As with the previous channels, use the Speaker Level Adjust buttons m to adjust the level as required so that the test tone is the same level as the other channels. When the adjustment is complete press the Test Tone button k twice so that the tone momentarily stops, and then begins to circulate.
