ADJUSTING THE SPEAKER OUTPUT LEVELS This section explains how to adjust the speaker output levels by using the test tone generator. When this adjustment is made, the output level heard at the listening position will be the same from each speaker. This is important for the best performance of the digital sound field processor, the Dolby Pro Logic decoder, Dolby Digital decoder and DTS decoder. Note • Since this unit cannot enter the test mode while headphones are connected to this unit, be sure to unplug the headphones from the PHONES jack when using the test tone. Before You Begin 1 Using the Test Tone (TEST DOLBY SUR.) Use the test tone to balance the output levels of the 5 speakers required for a surround sound system. The adjustment of each speaker output level should be made at your listening position with the remote control. After completing the adjustments, use VOLUME +/- at your listening position to check if the adjustments are satisfactory. 2,6 1 5 4 STANDBY /ON SPEAKERS A B BASS PROCESSOR EXTENSION DIRECT ON OFF D I G I TA L INPUT MODE INPUT D I G I TA L SURROUND VOLUME 6CH INPUT TUNER DSP A/B/C/D/E PRESET/ TUNING EFFECT PROGRAM PRESET TUNING /TUNING FM/AM MEMORY MODE EDIT MAN'L/AUTO FM AUTO/MAN'L MONO PHONES S VIDEO VIDEO L AUDIO R OPTICAL SILENT VIDEO AUX BASS TREBLE - + - + 23 1 Press STANDBY/ON to turn on the power.
