6.1 Speakers

The SPACE PR350 B contains extensive bass management adjustments, so that the bass signal can be re-routed to those loudspeakers capable of handling the low frequency information.

The following selections can be made in the config.speaker menu by using navigation keys described above:

Left speaker (L): Right speaker (R): Center speaker (C): Surround left speaker (SL): Surround right speaker (SR): Subwoofer (SUB):

SMALL or LARGE SMALL or LARGE SMALL or LARGE or OFF SMALL or LARGE or OFF SMALL or LARGE or OFF ON or OFF

The bass signal directed to speakers selected as SMALL, will be re-routed to the - subwoofer, or the L,R speakers (bass management).

If a speaker is turned off, the sound signal will be sent to the remaining speakers, which are selected as active (down mixing).

Special attention should be given to the subwoofer management:

For Dolby Digital 3/2 and DTS input stream a special low frequency channel (LFE) is normally included, which is indicated with a “.1” after the input stream indication, e.g. 3/2 .1 . The LFE channel produces an output at the subwoofer. That means even if all speakers are chosen LARGE, where no signal is send to the subwoofer by the bass management, signal will be send to the Subwoofer from the LFE input channel. For Stereo and ProLogic II no LFE channel is present. And if all speakers are chosen LARGE, the bass management does not send any signal to the subwoofer. In this case to have a subwoofer signal, the user can select the subwoofer – max bass ON option under the config.cross freq menu. In this case PR250 B takes the summed full range signal from the L and R channels and send to the subwoofer.

In case of using subwoofer (subwoofer is activated) in Stereo and Pro Logic mode, the user should therefore decide:

a ) Select L and R (or L,R,C,SL,SR in Pro Logic) to be SMALL. Then the low frequencies will be send to the subwoofer by the bassmanagement. The crossover frequency is set in the config.cross freq menu.

or

b)Select L and R (or L,R,C,SL,SR in Pro Logic) to be LARGE and then select Subwoofer – max bass ON in the config.cross freq menu. In this case the full range summed mono signal from the other channels, will be send to the subwoofer.

The implication of b) is that “double bass” is present in the system. That means the user should eventually chose a lower gain setting for the subwoofer, e.g. –4 to –8 dB depending on the sensitivity of the subwoofer relative to the other speakers.
