Denon ADV-M51 manual Parameters, Subwoofer SW FREQ. frequency, Assignment of low frequencies

NOTE:

•Select the speaker size not by the physical size of the speaker but by the speaker’s capacity to reproduce low frequencies of 100 Hz or less. If you do not know, determine the best setting by comparing the sound when the setting is set to “Small” and “Large”, keeping the volume low enough to prevent damage to the speaker.

NOTE:

•Select “Large” or “Small” not according to the actual size of the speaker but according to the speaker’s capacity for playing low frequency (approximately 100 Hz and below) signals. If you do not know, try comparing the sound at both settings (setting the volume to a level low enough so as not to damage the speakers) to determine the proper setting.

Parameters

Large…… Select this when using speakers that can fully reproduce

low sounds of below 100 Hz.

Small…… Select this when using speakers that do not provide

sufficient volume for playing low frequencies of 100 Hz and less. When this setting is made, frequencies below the frequency set at the subwoofer frequency setting are assigned to the subwoofer.

Yes/No…. Select “Yes” when a subwoofer is installed, “No” when a subwoofer is not installed.

If the subwoofer has sufficient low frequency playback capacity, good sound can be achieved even when “Small” is set for the front, speakers.

For the majority of speaker system configurations, using the SMALL setting for main speakers and Subwoofer On with a connected subwoofer will yield the best results.

ENGLISH

Subwoofer (SW FREQ.) frequency

•For the subwoofer frequency at the speaker setting screen, set the bass crossover frequency for playback from the subwoofer.

•Select “80 Hz”, “120 Hz”, “150 Hz” or “180 Hz” (-6 dB for each). Bass sound below these frequencies is played from the subwoofer.

(This is set to “150 Hz” by factory default.)

Assignment of low frequencies

•In the Dolby Digital, Dolby Pro Logic II, DTS, and virtual surround modes, the low frequency signals for channels whose speaker settings are set to “Small” are assigned to the subwoofer. The low frequencies of channels set to “Large” are played from those channels.

(If set to “120 Hz”, channels set to “Small” play sounds of 120 Hz and greater, while bass frequencies of under 120 Hz are played from the subwoofer.)

•In surround modes other than the ones listed above, low frequencies below the frequency set at the subwoofer frequency setting are played from the subwoofer regardless of whether the speakers are set to “Large” or “Small”.

•Set the subwoofer frequency according to the low frequency playback abilities of your speakers and subwoofer.

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.

•When the “LFE+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.

•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 are played from the subwoofer channel are only the low frequency signal range of LFE (only during Dolby Digital or DTS signal playback) and the channel specified as “SMALL” in the setup menu.

•Select the play mode that provides bass reproduction with body.

•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.
