ENGLISH System Setup 5 Press the CURSOR F or G button to set the distance from the surround R speakers to the listening position, then press the ENTER or CURSOR H button to switch to the surround back L speaker setting. 6 Press the CURSOR F or G button to set the distance from the surround back L speakers to the listening position, then press the ENTER or CURSOR H button to switch to the surround back R speaker setting. 7 Press the CURSOR F or G button to set the distance from the surround back R speakers to the listening position, then press the ENTER or CURSOR H button to switch to the subwoofer setting. 8 Press the CURSOR F or G button to set the distance from the subwoofer to the listening position, then press the ENTER or CURSOR H button to enter the setting and switch to the Subwoofer Mode setting. • The number changes in units of 1 foot each time one of the buttons is pressed. Select the value closest to the measured distance. • The difference in distance for the various speaker settings must not be greater than 20 ft. Setting the Subwoofer Mode and Crossover Frequency Set the subwoofer mode and crossover frequency mode according to the speaker system being used. 1 Press the CURSOR F or G button to select the subwoofer mode, then press the ENTER or CURSOR H button to enter the setting and switch to the crossover frequency setting. *SW Mode Norm Norm +Main 2 Press the CURSOR F or G button to select the crossover frequency, then press the ENTER or CURSOR H button to enter the setting and switch to the Test Tone setting. 60Hz *Cr.Over 80Hz 80Hz 100Hz 120Hz 135Hz 200Hz 180Hz 150Hz 2 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. System Setup 2 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. (• When "Subwoofer" is set to "No", the bass sound is output from the speakers set as "Large".) 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 higher frequency may improve frequency response for frequencies near the crossover frequency. 2 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 "Setting the Speaker Configuration" ( page 12, 13). • When the "LFE+MAIN" playback mode is selected, the low frequency signal range of channels set to "Large" is produced simultaneously from those channels and the subwoofer channel. In this playback mode, the low frequency range expands 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. • Selection of the "LFE" play mode will play the low frequency signal range of the channel selected with "Large" from that channel only. Therefore, the low frequency signal range that is played from the subwoofer channel is only the low frequency signal range of LFE (only during Dolby Digital or DTS signal playback) and the channels specified as "Small" in the setup menu. • Select the play mode that offers the fullest bass. • When the subwoofer is set to "Yes", bass sound is output from the subwoofer regardless of the subwoofer mode setting in surround modes other than Dolby/DTS. • In surround modes other than Dolby Digital and DTS, if the subwoofer is set to "Yes", the low frequency portion is always output to the subwoofer channel. For details, refer to "Surround modes and parameters" ( page 43). 14 ENGLISH
