System Speaker the Up Setting and Up Hooking
Multi Channel Surround Setup
xFront speaker size (FRONT)
Initial setting : LARGE
• If you connect large speakers that will effectively reproduce bass frequencies, select “LARGE”. Normally, select “LARGE”.
• If the sound is distorted, or you feel a lack of surround effects when using multi channel surround sound, select “SMALL” to activate the bass redirection circuitry and output the front channel bass frequencies from the sub woofer.
• When the front speaker is set to “SMALL”, the center, surround and surround back speakers are also automatically set to “SMALL” (unless previously set to “NO”).
pCenter speaker size (CENTER)
Initial setting : LARGE
• If you connect a large speaker that will effectively reproduce bass frequencies, select “LARGE”. Normally, select “LARGE”. However, if the front speakers are set to “SMALL”, you cannot set the center speaker to “LARGE”.
• If the sound is distorted, or you feel a lack of surround effects when using multi channel surround sound, select “SMALL” to activate the bass redirection circuitry and output the center channel bass frequencies from the front speakers (if set to “LARGE”) or sub woofer. *1
• If you do not connect the center speaker, select “NO”. The sound of the center channel will be output from the front speakers.*2
pSurround speaker size (SURROUND)
Initial setting : LARGE
•If you connect large speakers that will effectively reproduce bass frequencies, select “LARGE”. Normally, select “LARGE”. However, if the front speakers are set to “SMALL”, you cannot set the surround speakers to “LARGE”.
•If the sound is distorted, or you feel a lack of surround effects when using multi channel surround sound, select “SMALL” to activate the bass redirection circuitry and output the surround channel bass frequencies from the sub woofer or other “LARGE” speakers.
•If you do not connect surround speakers, select “NO”.*3
z*1~*3 correspond to the following Dolby Pro Logic modes
*1 NORMAL *2 PHANTOM *3 3 STEREO
xSurround back speaker size (SURR BACK)**
Initial setting : NO
This parameter can be set when the center speaker is set to “NO” and the surround speakers are set to “LARGE” or “SMALL”.
• If you connect a large speaker that will effectively reproduce bass frequencies, select “LARGE”. Normally, select “LARGE”. However, if the front speakers are set to “SMALL”, you cannot set the surround back speaker to “LARGE”.
• If the sound is distorted, or you feel a lack of surround effects when using multi channel surround sound, select “SMALL” to activate the bass redirection circuitry and output the center channel bass frequencies from the front speakers (if set to “LARGE”) or sub woofer. However, if the surround speakers are set to “SMALL”, the surround back speaker is automatically set to “SMALL”.
• If you do not connect a surround back speaker, select “NO”.
**This parameter is not available when “Surround speaker size (SURROUND)” is set to “NO”.
zAbout speaker sizes (LARGE and SMALL)
Internally, the LARGE and SMALL settings for each speaker determine whether or not the internal sound processor will cut the bass signal from that channel. When the bass is cut from a channel the bass redirection circuitry sends the corresponding bass frequencies to the sub woofer or other “LARGE” speaker. However, since bass sounds have a certain amount of directionality it best not to cut them, if possible. Therefore, even when using small speakers, you can set them to “LARGE” if you want to output the bass frequencies from that speaker. On the other hand, if you are using a large speaker, but prefer not to have bass frequencies output from that speaker, set it to “SMALL”.
If the overall sound level is lower than you prefer, set all speakers to “LARGE”. If there is not enough bass, you can use the equalizer to boost the bass levels. To adjust the equalizer see page 38.
xSub woofer selection (SUB WOOFER)
Initial setting : YES
• If you connect a sub woofer, select “YES”.
• If you do not connect a sub woofer, select “NO”. This activates the bass redirection circuitry and outputs the LFE signals from other speakers.
• In order to take full advantage of the Dolby Digital bass redirection circuitry, we recommend setting the sub woofer’s cut off frequency as high as possible.
