About Marsh Sound Design Products:
Simplicity: Marsh Sound Design products have simple controls on the outside-sophisticated, elegant circuitry on the inside Marsh Sound Design creates an intuitive design with clearly marked controls. Incorporated, are all the inputs and outputs you will need for ultimate flexibility for the future. Ease of setup comes naturally with Marsh Sound Design products, "Plug it in; Turn it on!"
Reliability: We start with robust construction and top-quality materials, the very seeds of reliability in performance. Then crash testing provides durability. Marsh Sound Design experience and expertise guarantee you years of excellent, music listening.
HT500s-Three Channel Amp:
300 watts,a high-end circuit with very low-noise FET's that are made even more linear by aa balanced, cascoded, complimentary differential input circuit.Servo-controlled, direct-coupled circuitry is used throughout for extremely high resolution.MSDŽ power amplifiers accept balanced(XLR) or unbalanced (RCA) Inputs, selectable via the rear panel. The output has two sets of 3-way binding posts for conveniently hooking up multiple speakers, or for bi-wiring certain high-end speakers.
