Speaker setup Level Setting 3 2 Level setting • This function is to set the level balance of each speaker. EN • The level range is from -6dB to +6dB. 3 Test tone • This function is available in DVD mode only. • When setting TEST TONE on, the unit will provide signals to each speaker respectively, so you can decide if any fine-tuning is needed for that speaker. • The test tone function can be activated even when there is no disc in the tray. Dynamic range setting In many listening situations, it is not recommended to set the volume too high, and thus the loudest sound must be compressed downwards in level. Likewise, the very quiet sounds would be inaudible and must be brought upwards in level to be heard. Dolby Digital satisfies these needs through the dynamic range controlling. Selects the dynamic range compression to fit the individual listening situation. The options are Softer, Soft and OFF. • Softer: Audio with highly compressed dynamic range. • Soft: Audio with partially compressed dynamic range. • OFF: Audio without compressed dynamic range. Note: Dynamic range is only applicable on Dolby Digital soundtrack. 1 Distance setup In order to make the surround sound more effective and suit the acoustic conditions in your listening room, you may need to delay the signal coming from some of the speakers by setting the distance between the speakers and your listening position. • This function is to set the distance of the front speaker, center speaker and rear speaker. (Only available when downmix function is OFF) • The distance range is from 5 feet to 30 feet 9
