B&K AVR505 SERIES 2 - Manual (Page 22)

AVR507 Series2 BACK CHANNEL AMPLIFICATION CONVERSION
If both zones of the AVR507 Series2 are being used, you have the option of either using an external amplifier
(see
page 19 ) or converting the surround back channels to supply the amplification for Zone B. The main
theater zone would then become a 5.1 surround system. This modification can be ordered directly from the
factory, or you may contact you local B & K dealer. If you any questions about converting the AVR507 Series2
receiver for Zone B amplification, please contact customer service at 716-656-0026 M-F 8:30 - 5:30 EST.
