NOTES:
— Assignment of low frequency signal range —
• The signals produced from the subwoofer channel are LFE signals (during playback of Dolby Digital or DTS signals) and the low frequency
signal range of channels set to “SMALL” in the setup. The low frequency signal range of channels set to “LARGE” are produced from
those channels.
— Crossover Frequency —
• When “Subwoofer” is set to “Yes” at the “Speaker Configuration Setting”, set the frequency (Hz) below which the bass sound of the
various speakers is to be output from the subwoofer (the crossover frequency).
• For speakers set to “Small”, sound with a frequency below the crossover frequency is cut, and the cut bass sound is output from the
subwoofer instead.
NOTE: For ordinary speaker systems, we recommend setting the crossover frequency to 80 Hz. When using small speakers, however,
setting the crossover frequency to a high frequency may improve frequency response for frequencies near the crossover
frequency.
— Subwoofer mode —
• The subwoofer mode setting is only valid when “LARGE” is set for the front speakers and “YES” is set for the subwoofer in the
“Speaker Configuration” settings (see pages 19, 20).
If “SMALL” is set for the front speakers or “NO” is set for the subwoofer, the subwoofer mode setting does not affect playback of low
frequency signal range.
• When the “+MAIN” playback mode is selected, the low frequency signal range of channels set to “LARGE” are produced
simultaneously from those channels and the subwoofer channel.
In this playback mode, the low frequency range expand more uniformly through the room, but depending on the size and shape of the
room, interference may result in a decrease of the actual volume of the low frequency range.
• When the “NORM” playback mode is selected, the low frequency signal range of channels set to “LARGE” are only produced from
those channels. In this playback mode there tends to be little interference of the low frequency range in the room.
• Try playing the music or movie source and select the playback mode providing the stronger low frequency range sound.
