Speaker Setup

•After you have installed this receiver and connected all the components, you should adjust the speaker settings for the optimum sound acoustics according to your environment and speaker layout.

•Even when you change speakers, speaker positions, or the layout of your listening environment, you should adjust the speaker settings, too.

■About the speaker size

The composition of the signals output from the different channels and the frequency response are adjusted automatically according to the combination of speakers actually being used.

•Select “Large” or “Small” not according to the actual size of the speaker but according to the speaker’s capacity for playing low frequency (bass sound below frequency set for the Crossover Frequency mode and below) signals.

Large : Select this when connecting speakers that can fully reproduce

sounds below crossover frequency(*) of your speaker.

Small : Select this when connecting speakers that cannot fully reproduce sounds below crossover frequency.

When this setting is selected, sounds below crossover frequency are sent to the subwoofer or speakers which are set to “Large”(when not using a subwoofer).

None : Select this when no speakers are connected.

When this is selected, sounds are sent to the speakers which are not set to None.

Yes / None : Select the desired depending on whether a subwoofer is connected or not.

•(*) : Crossover frequency is the frequency (Hz) below which the bass sound of each main speakers is to output from the subwoofer or from speakers which are set to “Large” (when not using a subwoofer).

•Refer to the operating instructions of the speakers to be connected. If the frequency range of your speaker is 100 Hz ~ 20 kHz, the crossover frequency have to be set to 100 Hz(or slightly higher).

•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.

•Depending or relationship between speakers, settings possible for each speaker are as follows:

Front L/R Center		Surr. L/R	Surr. Back	Subwoofer

■About the speaker distance

When enjoying multi-channel surround playback with Dolby Digital and DTS sources, etc., it is ideal that the center and surround speakers, etc. should be the same distance from the main listening position as the front speakers. By entering the distance between the listening position and each speaker, the delay times of center and surround speakers are automatically adjusted to create an ideal listening environment virtually as if the center and surround speakers were at their ideal locations respectively as below:
