Onkyo Comprehensive Guide to Level Calibration, LFE Settings and Speaker Calibration for Receivers

■Surround Back Ch

`1ch:

Select if only one surround back speaker L is connected.

`2ch:

Select if two (left and right) surround back speakers are connected.

Note

•If the “Surround Back” setting is set to “None”, this setting cannot be selected.

•If the “Powered Zone 2” setting is set to “Yes” and Zone 2 is turned on, this setting cannot be selected.

■LPF of LFE

(Low-Pass Filter for the LFE Channel)

`80Hz, 90Hz, 100Hz, 120Hz

`Off:

Low-Pass Filter is not applied.

With this setting, you can specify the cutoff frequency of the LFE channel’s low-pass filter (LPF), which can be used to filter out unwanted hum. The LPF only applies to sources that use the LFE channel.

Note

• If you’re using THX-certified speakers, select “80Hz”.

■Double Bass

This setting is NOT set automatically by

Audyssey 2EQ® Room Correction and Speaker Setup (➔ page 34).

`On

`Off(THX)

Turn this setting on to boost bass output by feeding bass sounds from the front left, right, and center channels to the subwoofer.

Note

•When the “Subwoofer” setting is set to “No” or the “Front” setting to anything other than “Full Band”, this setting is fixed to “- - -”.

•This setting is set to “On” automatically when the “Subwoofer” and “Front” settings are set for the first time to “Yes” and “Full Band” respectively.

•If you’re using THX-certified speakers, select “Off(THX)”.

Speaker Distance

This setting is set automatically by Audyssey 2EQ Room Correction and Speaker Setup (➔ page 34).

Here you can specify the distance from each speaker to the listening position so that the sound from each speaker arrives at the listener’s ears as the sound designer intended.

■Unit

`feet:

Distances can be set in feet. Range: 1.0ft to 30.0ft in

1.0foot steps.

`meters:

Distances can be set in meters. Range: 0.30m to 9.00m in 0.30 meter steps.

(The default setting varies from country to country.)

■Left, Front High Left, Center, Front High Right, Right, Surround Right, Surround Back Right, Surround Back Left, Surround Left, Subwoofer

`Specify the distance from each speaker to your listening position.

Note

•Speakers that you set to “No” or “None” in

“Speaker Configuration” cannot be selected (➔ page 54).

•When the “Powered Zone 2” setting is set to “Yes” and Zone 2 is turned on, the surround back and front high speakers cannot be used.

Advanced Operations

Level Calibration

This setting is set automatically by Audyssey 2EQ Room Correction and Speaker Setup (➔ page 34).

Here you can adjust the level of each speaker with the built-in test tone so that the volume of each speaker is the same at the listening position.

Note

•These settings cannot be calibrated in either of the following cases:

–The “Audio TV Out” setting is set to “On” (➔ page 66).

–“HDMI Control(RIHD)” is set to “On” (➔ page 65) and you’re listening through your TV speakers.

–The AV receiver is muted.

■Left, Front High Left, Center*1, Front High Right,

Right, Surround Right, Surround Back Right, Surround Back Left, Surround Left

`–12dBto 0dB to +12dB in 1 dB steps.

■Subwoofer*1

`–15dBto 0dB to +12dB in 1 dB steps.

Note

•Speakers that you set to “No” or “None” in

“Speaker Configuration” cannot be selected (➔ page 54).

•When the “Powered Zone 2” setting is set to “Yes” and Zone 2 is turned on, the surround back and front high speakers cannot be used.

•The test tone is output at the standard level for THX, which is 0 dB (absolute volume setting 82). If you normally listen at volume settings below this, be careful because the test tone will be much louder.

*1 For the center speaker and subwoofer, the level settings made by using the Quick Setup are saved in this menu (➔ page 48).

Tip

•If you’re using a handheld sound level meter, adjust the level of each speaker so that it reads 75 dB SPL at the listening position, measured with C-weighting and slow reading.
