Setting bass sound
7 Setting subwoofer output�SUBWOOFER OUT
You can select the type of the signal which can be transmitted through the subwoofer. In other words, you can determine whether or not the bass elements of the front speaker channels are transmitted through the subwoofer regardless of the front speaker size setting (either �SMALL� or �LARGE�). SUBWFR OUT: LFE Select to emit only the LFE signals (while playing Dolby Digital and DTS software) or the bass elements of the �SMALL� front speakers (while playing any source other than above). SUBWFR OUT: LFE+MAIN Select to always emit the bass elements of the front speaker channels (MAIN). While playing Dolby Digital and DTS software, the bass elements and the LFE signals are both emitted. Initial setting: SUBWFR OUT: LFE NOTE When �SUBWOOFER� is set to �SUBWOOFER: NO� (see page 21), this function is not available.

Using the Midnight mode �MIDNIGHT MODE
You can enjoy a powerful sound at night using the Midnight mode. � Once you have made an adjustment, it is memorized for each source. MIDNIGHT MODE: OFF Select when you want to enjoy surround with its full dynamic range. (No effect applied.) MIDNIGHT MODE: 1 Select when you want to reduce the dynamic range a little. MIDNIGHT MODE: 2 Select when you want to apply the compression effect fully (useful at night). Initial setting: MIDNIGHT MODE: OFF

From the remote control
You can also make adjustments the following way from the remote control. Set the mode selector to �AUDIO/TV/VCR/STB.� Press SOUND, then press MIDNIGHT repeatedly to select either one of the above. NOTE After pressing SOUND, the numeric buttons work for sound adjustments. To use the numeric buttons to operate your target source, press the corresponding source selecting button before operation; otherwise, the remote control may not work as you intend.

7 Setting the crossover frequency�CROSSOVER
Small speakers cannot reproduce the bass sounds efficiently. If you use a small speaker in any position, this receiver automatically reallocates the bass sound elements assigned to the small speaker to the large speakers. To use this function properly, set this crossover frequency level according to the size of the small speaker connected. � If you have selected �LARGE� for all speakers (see page 21), this function will not take effect (�CROSSOVER: OFF� appears). CROSSOVER: 80Hz Select when the cone speaker unit built in the speaker is about 12 cm.

CROSSOVER: 100Hz Select when the cone speaker unit built in the speaker is about 10 cm. CROSSOVER: 120Hz Select when the cone speaker unit built in the speaker is about 8 cm. CROSSOVER: 150Hz Select when the cone speaker unit built in the speaker is about 6 cm. CROSSOVER: 200Hz Select when the cone speaker unit built in the speaker is less than 5 cm. Initial setting: CROSSOVER: 150Hz NOTE Crossover frequency is not valid for the HEADPHONE and 3D HEADPHONE modes.

7 Setting the low frequency effect attenuator �LFE ATT
If the bass sound is distorted while playing back software encoded with Dolby Digital or DTS, set the LFE level to eliminate distortion. � This function takes effect only when the LFE signals come in. LFE ATT: 0dB LFE ATT: �10dB Normally select this. Select when the bass sound is distorted.

Initial setting: LFE ATT: 0dB
