Towards the end of last year, MidiLand released a revised version of their S4 7100 surround sound system, touted as the S4 7100 Plus. The primary change to the system is the addition of a Dolby Digital decoder that replaces the external control box that had been included with the original system. The original system required the user to already have the capabilities to decode the surround info, such as with a 5.1 channel sound card; now, it is offered as a complete package that will provide full Dolby Digital right out of the box.
Now that the system is a full package, it’s worth taking another look at. The subwoofer has changed some, as all of the audio processing (including crossover) is now in the decoder box. The system includes the decoder, remote, sub, five identical satellites, and cabling for the system. MidiLand has moved away from the small control module that could be mounted in a drive bay and was included with the older system. Here’s what MidiLand says about their system:
