I buy the Jensen JHT350 Home Theater System for use in a 8 ' x 10 ' exercise room and use it mainly to watch music and concert dvd while work out . the video quality be very good , although it be on occasion necessary to open and close the disk drawer two or three time before a dvd will load in the player . the audio can be easily hear over the noise of a treadmill and exercise bike , with plenty of volume leave to burn . the audio quality be acceptable , but can not compare with the near concert hall quality produce by more sophisticated home theater system . there be a distinct tinny sound in the upper register at high volume . the subwoofer be passive , which mean it lack its own amplifier and power supply and use instead the amplifier in the receiver . the unit perform Dolby Digital 5.1 decoding , but have no dt decoder . there be both digital coaxial and digital optical audio output , which make it possible to connect the dvd player to a better sound system , but there be no digital audio input . this make it impossible to obtain digital sound from a cable or satellite receiver . there be , however , leave and right analog stereo input and the prologic feature can use to obtain simulated surround sound from a external source , such as a tv or cable receiver , connect to these input . the FM receiver pull in a fair number of station , but the AM receiver pick up only two station , and I be located in a major metropolitan area which have numerous AM station . the button on the remote be not very intuitive and be poorly arrange . once the unit be turn off , it have no memory of any setting for a particular dvd , include the place in the dvd where playback be stop . the operator ' manual section deal with some of the audio setting be incomprehensible and my email to Audiovox and its agent request clarification have not yield any useful information . in summary , this item offer some feature find in better home theater system for a relatively low price , but it also have quite a few limitation .
