I have a Norcent DP1800, but no manuel or remote. Need user info. For radio I'm using a 75ohm coax connector & an indoor Dipole FM antenna. Poor reception and no AM. Unable to get Surround sound. Need instructions for set-up,placement and connections of speakers. How to connect to TV with comcast digital box as well as a multi-disc CD player if possible. Unable to program comcast universal remote to use with system.
