    I have my Denon3802 setup - Front spkers - Large
    Sub - LFE

    so that (as it says in the manual) my sub should only work when playing the .1 bit of 5.1 Dvds, (stereo should just use the two front speakers)

    But, if I play a Cd in Stereo,there is still bass going down the LFE from the subwoofer output to my subwoofer.

    Why is this happening?
    Does anybody know.

    If you don't want the sub to work during cd playback either switch the sub off or adjust your sw to off in the Channel volume menu on the amp for the cd source. Using direct mode uses the players dac's whereas if you use stero mode on the amp the amps dacs are being used.

    Its coz i'm setting my amp up with a Rel, which takes its bass for stereo off the right and left front speaker channels, rather than the LFE

    Direct mode bypasses the processors so no sub out.

    Just to clear things up a bit about the DENON. DIRECT mode bypasses any Bass Management and sends full range signals to the front left & right channels regardless of what you have selected in the speaker setup menu (small/large etc).

    DIRECT also has subwoofer output which can be switched OFF if need be.

    DIRECT will also use the amps DAC's when the source input is DIGITAL. These are bypassed with an ANALOGUE signal.

    STEREO mode uses bass management and takes into account the speaker setup that you have selected (small/large etc).

    There is still output from the subwoofer output whether the Amp is on Direct or Stereo. I have all speakers set to large, and I am using the anaolgueCD inputs.
    This seems inconsistent with the instructions that says there should be no output from sub/LFE/.1 channel from a stereo source when setup this way. (All base to the fronts).
    Also
    when i connect to my Rel with both the LFE and the other connecter concurently (like it says in the instructions) I seem to be getting Mid range as well as bass coming from the subwoofer.

    What is going on?

    I've followed the manual for the 3802 and the REL.

    What could I be doing wrong?

    It's because you are using BOTH the High Level and Low Level connections on the REL. Disconnect the High Level (neutrik) and you shouldn't get any signal going to the sub.

    With the High Level connected the sub is receiving a signal from the front left and right channels of the amp (which are set to Large).

    With your REL you can have the best of both worlds if you want i.e all speakers set to Small, all bass to Sub for movies and then for music use the DIRECT mode and you retain full range signals for the front speakers (with or without sub output via low level). You would need to use Mode 2 on the REL (if your model has this Mode switch) as this ignores the sub crossover at low level as the crossover frequency will be set by the amp e.g 80hz.

    If you use the High Level connector as well then just adjust the crossover and volume on the sub to blend with your front speakers e.g 50hz.
