I sent this query to B&W (distributors of Rotel in the UK).... "Can you comment on reports from the USA that this processor has a "double-bass" problem which Rotel have been unable to completely eradicate. This problem is described as the processor, in certain decoding conditions, sending low frequency effects (LFE's) to both the subwoofer and the front L/R speakers when the LFE's should be sent to the subwoofer only." I got this reply... "From what I have been told by Rotel, there is certainly no "doubling up". If you use the preferred method of connecting the digital output from the DVD player into the processor it will decode the 5.1 digital stream as par the specification set down by Dolby/DTS etc. If you are using the multi channel output from your DVD player into the RSP-1066, for example for DVD-A and SACD, which on almost all discs does not have a dedicated .1 channel for bass. It will take a signal from the front left and right speaker to feed to the subwoofer, as this was felt to be useful for people who wanted to make use of their subwoofer for these sources.
