This greatly compresses the dynamic range and lets you view movies late at night at low volumes. Unlike analog limiters, the levels are predetermined and provide a very natural compression. Amplifier Operations LEVEL menu parameters x T. TONE (Test tone) Lets you adjust the speaker levels and balance while listening to the test tone from your listening position. For details, see "8: Adjusting the speaker levels and balance (TEST TONE)" (page 31). x FRT BAL (Front speaker balance) Lets you adjust the balance between front left and right speakers. x CNT LVL (Center speaker level) x SL LVL (Surround left speaker level) x SR LVL (Surround right speaker level) x SW LVL (Sub woofer level) 39GB Adjusting the tone (TONE menu) You can use the TONE menu to adjust the tonal quality (bass/treble level) of the front speakers. For details on adjusting the parameters, see "Navigating through menus" (page 36) and "Overview of the menus" (page 37). Settings for the surround sound (SUR menu) You can use the SUR menu to select the sound field you want for your listening pleasure. For details on adjusting the parameters, see "Navigating through menus" (page 36) and "Overview of the menus" (page 37). TONE menu parameters x BASS LVL (Front speaker bass level) x TRE LVL (Front speaker treble level) SUR menu parameters x S. F. SELCT (Sound field selection) Lets you select the sound field you want. Note The receiver lets you apply the last selected sound field to an input whenever it is selected (Sound Field Link). For example, if you select "HALL" for the SA-CD/CD input, then change to a different input and then return to SA-CD/CD, "HALL" will automatically be applied again. x EFFECT (Effect level) Lets you adjust the "presence" of the surround effect for sound fields selected with the MOVIE or MUSIC buttons and for "HP THEA" sound field. MAX The surround effect is maximum. 40GB Settings for the tuner (TUNER menu) You can use the TUNER menu to set the FM station receiving mode and to name preset stations. When the sub woofer is set to "NO", the front speakers are automatically set to "LARGE". · SMALL 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 speakers are set to "SMALL", the center and surround speakers are also automatically set to "SMALL" (unless previously set to "NO"). x SUR SPK (Surround speakers) · LARGE If you connect large speakers that will effectively reproduce bass frequencies, select "LARGE". However, if the front speakers are set to "SMALL", you cannot set the surround speakers to "LARGE". · SMALL 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. · NO If you have not connected surround speakers, select "NO". Tip The "LARGE" and "SMALL" settings for each speaker determine whether 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" speakers. However, since bass sounds have a certain amount of directionality, it is 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". [. . . ] Additional Information The source image input to the HDMI jack on the receiver is not output from the TV. · Depending on the playback component, you may need to set up the component. · Select the source component using the input buttons. continued 65GB Tuner The FM reception is poor. · Use a 75-ohm coaxial cable (not supplied) to connect the receiver to an outdoor FM antenna (aerial) as shown below.
