Product Research

Inputs and Outputs


Overview: The MAINstage HD is an all-in-one set-top box that houses the following: two 2" x 2-3/4" full-range speakers, one 4" subwoofer, and an internal amplifier that sends 20 watts to each of the main speakers and 40 watts to the subwoofer. This unit accepts input from digital and analog sources. The Zoran VMD algorithms allow the MAINstage HD to extract spatial information from mono, stereo, and Dolby encoded material, allowing you to enjoy convincing sound from just the two built-in high-quality drivers and built-in subwoofer.

Linear Magnetic Drive Technology: The speakers in the MAINstage HD use patented Linear Magnetic Drive technology and ultra-powerful neodymium-sandwich magnets that allow them to go deeper, play louder and cleaner than otherwise possible.

Angle Ease Leveling System: The AngleEase leveling system allows you to angle the MAINstage HD to suit its position, angled directly at you.

Speaker Protection: The MAINstage HD uses a state-of-the-art digital amplifier section that allows significantly higher music peaks to be heard cleanly. If the system is played at levels that might harm the speakers, the amplifiers will shut down to protect the speakers from damage.

Auto Turn-on/Turn-off: The MAINstage HD has an automatic turn-on/turn-off feature. It will turn off (standby mode) when the source equipment (TV, etc.) has no sound output for approximately one minute (immediate for digital inputs) and will immediately turn on again when a signal is present.

Rear Output: There is a 3.5mm mini-jack output for rear channel information. You can add a second MAINstage HD or another type of amplified speakers for a complete 5.1 surround experience.

Subwoofer Output: There is a 3.5mm mini-jack output for a subwoofer. You can add a Soundmatters SUBstage 100 or another brand powered sub.

Magnetically Shielded: The MAINstage HD is magnetically shielded, and can be placed close to a computer monitor or television without distorting the image on your screen.

Placement: For optimum performance and stereo imaging, the system should be placed directly in front of you. Mounting the system at or above ear level typically provides the best sound. Use the included AngleEase mounting hardware to angle the MAINstage HD so the front points directly at you. Make sure there is space above, behind, and ideally at either side of the system to allow bass to flow into the room.
