This allows the Receiver to process any surround sound digital source to exactly match your system and giveyou the ultimate surround sound experience.There are three pieces of vital information which are outlined in the sections: ‘Speaker Types’, ‘Speaker Distances’ and‘Speaker Levels’. The way you enter this information manually into the Receiver is given later in the ‘Setup Menus’ section.When calibrated using EZ Set EQ calibration app, the speaker levels and delays will NOT be established automatically whenthe equalization is turned on. The speaker size, speaker distance and speaker levels settings must be entered manually. It isimportant to understand why these speaker settings must be entered, which is why this section is presented before the sectionon equalization.SPEAKER TYPESYou need to set the type of speakers that you have connected to your Receiver:Large Capable of full frequency range reproduction.Small Not capable of full frequency range reproduction at the low frequency end.None Speaker not present in your configuration.The terms ‘Large’ and ‘Small’ do not necessarily relate to the physical size of your speakers. As a rule of thumb, if a speakercannot reproduce a flat frequency response down to about 40Hz (and very few can!) it is often better to consider them as‘Small’ for setup purposes of home cinema.When a speaker is set to ‘Small’, very low frequency sounds are redirected away from that speaker to a ‘Large’ speaker or asubwoofer, which are far better suited to reproducing these low frequency sounds. Many prefer to set even very full-rangespeakers to ‘Small’ to optimize the dynamic range of the system and to more fully utilize the EZ Set EQ with bassmanagement enabled to ensure smooth subwoofer to main loudspeaker blending.Note that it is not possible to set all speakers to ‘Small’ unless there is a subwoofer in your speaker configuration. If you do nothave a subwoofer, you will be forced to set your front speakers to ‘Large’. (Some users may wish to automatically override the‘Small’ speaker setting for purely stereo music listening when not watching movies. This can be achieved in the ‘Source Setup’menu ( see SOURCE SETUP)Speaker CrossoverIf you have set any speakers as being ‘Small’, then you will be required to set a value for the crossover frequency. This is thefrequency below which signals are filtered away from these Small speakers and redirected to the subwoofer. 80Hz is usuallythe best crossover frequency, since it sends non-directional low frequencies to the subwoofers which are best-suited to handlelow frequencies and can be placed optimally to reproduce only the lowest frequencies.Amp AssignIt is possible to assign your rear surround amplifier channels to Front Height or Top Middle for Dolby Atmos speakerconfiguration.In addition, the rear surround amplifier channels can be assigned to provide a stereo downmix of the Main zone to asecondary location of the home, called Party mode. You can also assign these channels to bi-amplify the front left/rightchannels.
