JVC RX-D411S Turning the frequency optimizing function off, Unplug the earphone-type microphones

6Unplug the earphone-type microphones.

•When unplugging the microphones, pull on the plug, not the cord itself.

NOTES

•Do not press any buttons on the remote control or the front panel of the receiver during Precise Surround Setup; otherwise, the receiver stops setting and returns to the normal operation mode.

–After “COMPLETE” is displayed, the Precise Surround Setup results are applied to the speaker settings.

•The speaker size measured by Precise Surround Setup may be different from that of the manual setting recommendation (see page 30). Precise Surround Setup measures the speaker size not only by the cone speaker size but also by the other speaker features.

•There may be a case that the receiver fails to detect subwoofer and does not activate it (no optimized test tone comes out of the subwoofer).

In such a case, set the volume level of the subwoofer higher and perform Precise Surround Setup again.

•When you change your listening environment, such as speakers, speaker position, your listening position or so, perform Precise Surround Setup again to optimize the speaker settings.

•Depending on the listening environment, Precise Surround Setup may not measure the speaker settings accurately. In such a case, adjust the settings manually. See pages 29 to 32.

•The supplied earphone-type microphones cannot be used as headphones.

7 Turning the frequency optimizing function off

After performing Precise Surround Setup, the receiver optimizes the frequency response for each speaker. You can turn the frequency optimizing function off.

Press PSS to turn the frequency optimizing function off.

7 Checking the frequency responses corrected by Precise Surround Setup

You can check the current settings of the frequency responses with test tones from speakers and the indications on the display when the frequency optimizing function is activated.

From the remote control ONLY:

1Press TEST to check the frequency response of each speaker on the display.

TEST

•A test tone also comes from each speaker in the following order:

FL (Left front speaker) = C (Center speaker) = FR (Right front speaker) = SR (Right surround speaker) = SBR (Right surround back speaker)* = SBL (Left surround back speaker)* = SL (Left surround speaker) = SW (Subwoofer) * When using a single speaker for the surround back

speaker, the test tone comes out of “SB (Surround back speaker)” instead of “SBR” and “SBL.”

•The frequency response of each speaker appears on the display as follows:

EX. 1: When a test tone comes from the left front speaker

• Each time you press the button, the frequency optimizing	Current speaker			Frequency response
function alternates between on and off.						+9 dB
When the function is activated, the PSS indicator is lit.

						–9 dB
This function is not available:		Low		Frequency

– Until Precise Surround Setup has been completed at least once;
otherwise, “NO PSS” appears on the display.	EX. 2: When a test tone comes from the subwoofer
– When selecting “A MULTI” for the audio input setting (see page 12).
– When multi-channel PCM signals (see page 41) are coming in with							Crossover
selecting “HDMI” for the audio input setting (see page 12).
							frequency
			80 Hz		200 Hz

2 Press TEST again to stop the test tone.

NOTE

While the PSS indicator is off, pressing TEST generates test tones without showing frequency responses. See page 36.
