Rotel's excellent preamp processor from a few years ago. Has Dolby Digital 5.1 or DD EX, Dolby Pro Logic IIx, DTS 501 and DTS ES Matrix, DTS ES Discrete 6.1, DTS Neo 6 and many DSP music playback modes for simulating surround sound with 2 channel source material. Does not have HDMI ins and outs, but does have component video, S-video, composite video, optical and coax digital inputs and outputs. 7.1 surround capable (has surround and back channel outputs!) If your older 5.1 or 7.1 preamp died and you're not ready to spend $2000-5000 on a new one yet, this one will fill the part nicely and look and sound great! Can also be used as just an excellent stereo preamp if your system isn't a surround sound one too! Included is the original programmable remote and owner's manual. Paypal included in the price. Would like to sell this quickly so will accept the best offer I get over the next 30 days of the ad! NEW, LOWER PRICE FOR QUICK SALE!!
