Speaker Configuration

This setting is set automatically by

Audyssey MultEQ® XT32 Room Correction and Speaker Setup (➔ page 37).

With these settings, you can specify which speakers are connected and a crossover frequency for each speaker. Specify “Full Band” for speakers that can output low frequency bass sounds adequately, for example, speakers with a good sized woofer. For smaller speakers, specify a crossover frequency. Sounds below the crossover frequency will be output by the subwoofer instead of the speaker. Refer to your speaker’s manuals to determine the optimum crossover frequencies. If you set up your speakers using Audyssey MultEQ XT32 Room Correction and Speaker Setup, please make sure manually that any THX speakers are set to “80Hz(THX)” crossover.
