Denon AVR-5800 Setting the Surround Back channel, Assignment of low frequency signal range

NOTES:

— Assignment of low frequency signal range —

•The only 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 menu. The low frequency signal range of channels set to “LARGE” are produced from those channels.

— 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 page 19).

•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 - THX” 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. THX is recommended in this play mode so that bass interference is less likely to occur in the room.

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

Enter the setting.

The System Setup Menu reappears.

THX surround EX/DTS ES Auto Flag Detect Mode (AFDM) setting

OFF	Set the “OFF” mode to perform 6.1-channel playback with conventional 5.1-channel sources or sources on which the
	identification signal described below is not recorded.
ON	This function only works with software on which a special identification signal is recorded. This software is scheduled to go
	on sale in the future.
	This is a function for automatically playing in the 6.1-channel mode using the surround back speakers if the software is recorded
	in THX Surround EX or DTS-ES or in the normal 5.1-channel mode without using the surround back speakers when the software
	is not recorded in THX Surround EX or DTS-ES.
Non-Flag Source SB ch Output setting
OFF	Playback is conducted without using the surround back speaker.
Non MTRX	Playback is conducted using the surround back speaker. The same signals as those of the surround channels are output from
	the surround back channel.
THX surround EX/DTS ES		..........Playback is conducted using the surround back speaker.
		Surround back channel is reproduced using digital matrix processing.

NOTES:

•The “SB CH Auto Flag Detect” setting screen is displayed when the surround back speaker is set to “Large” or “Small” at “Speaker Configuration”.

•The surround back speakers can also be turned on and off using the “SB CH OUT” surround parameter. (See pages 51.) Select the setting according to the program source to be played.
