Setting the speaker distance
�FRNT D (front speaker distance), CNTR D (center speaker distance), SURR D (surround speaker distance), BACK D (surround back speaker distance)
The distance from your listening point to the speakers is another important element to obtain the best possible sound from the Surround and DSP modes. You need to set the distance from your listening point to the speakers. By referring to the speaker distance setting, this system automatically sets the delay time of the sound through each speaker so that sounds through all the speakers can reach you at the same time. Set the distance from the listening point to each speaker with the range of 0.3 m to 9.0 m (in 0.3 m intervals).
NOTE: If you have selected �NO� for �BACK SP� (see page 24), you cannot set the speaker distance for the surround back speaker.

Setting the crossover frequency�CROSS
Small speakers cannot reproduce the bass sounds efficiently.
