Also, the center speaker can not be set more that 5 feet (1.5 meters) closer than the front speakers. Likewise, the rear speakers can not be set farther away than from the listening position than the front speakers. And they can be no more than 15 feet (4.5 meters) closer. This is because incorrect speaker placement is not conducive to the enjoyment of surround sound. Please note that, setting the speaker distance closer than the actual location of the speakers will cause a delay in the output of the sound from that speaker. In other words, the speaker will sound like it is farther away. For example, setting the center speaker distance 3~6 feet (1~2 m) closer than the actual speaker position will create a fairly realistic sensation of being “inside” the screen. If you cannot obtain a satisfactory surround effect because the rear speakers are too close, setting the rear speaker distance closer (shorter) than the actual distance will create a larger soundstage. Adjusting these parameter while listening to the sound often results in much better surround sound. Give it a try! p Distance unit (DIST. UNIT) Initial setting : FEET Lets you select either feet or meters as the unit of measure for setting distances. 1 foot corresponds to a 1 ms difference. 16 Adjusting the speaker volume Use the remote while seated in your listening position to adjust the volume of each speaker. Note This unit incorporates a new test tone with a frequency centered at 800 Hz for easier speaker volume adjustment. 1 Press 1/u to turn on the receiver. 2 Press TEST TONE on the supplied remote. You will hear the test tone from each speaker in sequence. 3 Adjust the volume level so that the volume of the test tone from each speaker sounds the same when you are in your main listening position. • To adjust the balance of the front right and front left speakers, use the BALANCE control on the front of the receiver. • To adjust the balance of the rear right and rear left speakers, use the REAR BALANCE parameters in the SURROUND cursor mode (see pages 31 and 32). (The rear balance can also be adjusted from the remote.) • To adjust the volume level of the center speaker, press the LEVEL CENTER +/– buttons on the remote. • To adjust the volume level of the rear speakers, press the LEVEL REAR +/– buttons on the remote. 4 Press TEST TONE on the remote again to turn off the test tone. z You can adjust the volume level of all speakers at the same time Rotate MASTER VOLUME on the main unit or press MASTER VOLUME +/– on the remote. Notes • The rear balance, center level, and rear level are shown in the display during adjustment. • Although these adjustments can also be made via the front panel using the CURSOR MODE menu SURROUND parameters (when the test tone is output, the CURSOR MODE switches to the SURROUND parameters automatically), we recommend you follow the procedure described above and adjust the speaker levels from your listening position using the remote control. z When setting the volume levels for each speaker Let’s assume that you have matched the sound levels of all the speakers using the test tone. Although this lays the foundation for high quality surround sound, it may be necessary to make further adjustments while listening to playback of actual software. This is because most software contains center and rear channels recorded at slightly lower levels than the two front channels. When you actually playback software recorded in multi channel surround you will notice that increasing the center and rear speaker levels produces a better blend between the front and center speakers and greater cohesion between the front and rear speakers. Increasing the level of the center speaker about 1 dB, and the rear speakers about 1~2 dB is likely to produce better results. In other words, in order to create a more cohesive soundstage with balanced dialog, we recommend that you make some adjustments while playing your software. Changes of only 1 dB can make a huge difference in the character of the soundstage. Hooking 17 Before You Use Your Receiver Before turning on the receiver Make sure that you have: • Turned MASTER VOLUME to the leftmost position (0). • Selected the appropriate front speakers (see “8 SPEAKERS selector” on page 21). • Set BALANCE to the center position. Clearing the receiver’s memory Before you use your receiver for the first time or when you want to clear the receiver’s memory, do the following. 1/u Hooking Up and Setting Up the Speaker SystemSOUND FIELD ON/OFF DISPLAY EQ ON/OFF INPUT MODE DIRECT TUNING BASS BOOST SOUND FIELD GENRE MODE MUTING BALANCE L R 5 0 1 3 9 7 4 6 2 8 10 ••• • • • • • • • • • • • •• • • • • • • • • • • • ••• • PHONES SPEAKERS SET UP SURROUND EQUALIZER CURSOR MODE MEMORY PRESET – TUNING + AOFF A+B B gMASTER VOLUME DISPLAY FM/AMFM MODE – TUNING + SLEEP INDEX SOUND FIELD BASS BOOST EQ SOUND FIELD ON/OFFFUNCTION MULTI CHANNEL DECODING SHIFT 1 6 2 7 3 8 4 9 5 0 VIDEO 1 VIDEO 2 DVD/LD TV/DBS TAPE/MD CD TUNER PHONO...
