Features of the processor: Dolby Prologic, Dolby Digital & DTS Digital Decoder Total of 4 digital inputs, 2 optical and 2 coaxial 6-channel analog input facilities enable external decoder connection for throughput to a receiver. Speaker selector lets you match output to your speaker configuration and the presence or absence of a subwoofer. Dynamic range compression on/off switch lets you keep the full range of sound audible when listening at low volume, for natural results during night-time entertainment. Center/rear channel delay time control. Test tone, muting, and dimmer functions. Master volume control knob, Wireless remote. This is a used, but in good condition processor. It does have a few small scratches on the top. I do not have the original box, but do have the manual and remote. I am selling the processor as I have upgraded my receiver and no longer need the processor. I am asking $120 plus actual shipping. Thanks for looking.
