Crossover (Crossover Frequency)

This setting is set automatically by the Audyssey 2EQ™ Room Correction and Speaker Setup function (see page 37).

This setting only applies to the speakers that you specified as “Small” in the “2-2. Sp Config (Speaker Configuration) (TX-SR507)” on page 66.

To get the best bass performance from your speaker system, you need to set the crossover frequency according to the size and frequency response of your speakers.

Use the diameter of the smallest speaker in your system when choosing the crossover frequency.

Speaker cone diameter	Crossover frequency
Over 8 in. (20 cm)	40/50/60Hz*
6-1/2 to 8 in. (16–20 cm)	80Hz
5-1/4 to 6-1/2 in. (13–16 cm)	100Hz (default)
3-1/2 to 5-1/4 in. (9–13 cm)	120Hz
Under 3-1/2 in. (9 cm)	150 /200Hz*

*Choose the setting suitable for the speaker.

Notes:

•For a more accurate setting, look up the frequency response in the manuals supplied with your speakers and set accordingly.

•Choose a higher crossover frequency if you want more sound from your subwoofer.

DoubleBass

This setting is not set automatically by the Audyssey 2EQ Room Correction and Speaker Setup function (see page 37).

With the Double Bass function, you can boost bass output by feeding bass sounds from the front left, right, and center to the subwoofer. This function can be set only if the “Subwoofer” setting is set to “Yes”, and the “Front” setting is set to “Large” in the “2-2. Sp Config (Speaker Configuration) (TX-SR507)” on page 66.

On: Double Bass function on. Bass from the front left and right channels is also fed to the subwoofer (default).

Off: Double Bass function off.
