You should always perform System Setup after first installing your processor and after adding/changing speakers 
or sources or rearranging your listening area. Check that the remote is in B&K mode.

The speaker’s menu lets you tell your processor how many speakers you have in your system, the relative size of 
the speakers, and their location in the room. This is the most important setup procedure you will perform. The 
processor comes from the factory setup for 7 small speakers and a subwoofer. If this does not match your 
speakers then audio information will be lost. For example, if you do not currently have a center channel speaker 
and you do not perform this setup procedure, the center channel information will be lost. If you perform this setup 
correctly, the processor will know that you have no center channel speaker and send this information to your front 
left and right speakers (along with the normal front left and right information) so no audio information is lost.  

 

Speaker size generally refers to the size of your speakers. Audio material, particularly Dolby Digital and DTS 
movies, often contain large amounts of bass. If this bass information is sent to small speakers that are incapable 
of reproducing so much bass, then the bass information will be lost or distorted. TOO MUCH BASS MAY 
DAMAGE MANY SMALL SPEAKERS. By telling your processor the size of your speakers, it will be able to 
intelligently route the bass to speakers that can reproduce it correctly. Typically, all bookshelf or satellite speakers 
are considered small. Smaller floor standing speakers with single woofers 8” or less should also be considered 
small. Floor standing speakers with 10” or larger woofers or multiple smaller woofers may be considered large. 
These are general guidelines only - if you are unsure consult your speaker manufacturer or check with the dealer 
if they are unsure. If you have all small speakers we strongly recommend use of a subwoofer. If your front left and 
right speakers (or more) are large then you may not require a subwoofer, but you may still get better results using 
a subwoofer, especially with Dolby Digital and DTS movies. All THX certified speakers are small, regardless of 
their physical size, and should be used in audio systems along with a subwoofer.
