Embodiments of systems and methods are described for providing backwards compatibility for legacy devices that are unable to natively render non-channel based audio objects. The power take-off unit and the rear drive module can each be equipped with a two-speed range shift unit which, under the control of the control system, permits establishment of high and low speed drive connections. The inlets direct the gasses from the reaction chamber into the conduit, and the outlet exhausts the gasses from the conduit. A film scanner adapted to this method has a digitizing device and also a device for controllable correction of the converted image data.
