Each channel contains a low distortion, high level, wide bandwidth, nickel-core output transformer, with individual Common points. [. . . ] Assembly is simple: remove the top cover, install the board in place, and secure with the supplied mounting screws. The Option 44 can also be used as an inexpensive transformer assembly without the FLT 22. When rack space is not available, the Option 44 can be attached almost anywhere using screws and standoffs.

FLT 22 LINE TRANSFORMERS Professional Audio Products Data Sheet Rear Panel Block Diagram Application Information The FLT 22 fills the need of adding output isolation balancing transformers to any line-level equipment. It is a convenient alternative to the expense and clutter of adding loose or in-line transformers. Mounting The FLT 22 is packaged in a standard Rane Flex chassis which is compatible with all HR products and accessories. When used with other Flex products, the FLT 22 may be mounted in the FVR 10 Vertical Rack. Alternatively, choose one of the horizontal mounting kits to mount one or two units side-by-side into a standard 19" rack. Note that two units equipped with OPTION-44s and mounted horizontally provide 8 channels of transformer output isolation in only one rack space. Chassis Grounding A tapped hole for a #6-32 screw is provided for chassis grounding purposes. If the grounding integrity of the rack screws is in doubt, then run a wire from this tapped hole to a known good ground. Use high-quality wire and choose the grounding method appropriate for the application. [. . . ] W. , Mukilteo, WA 98275-5098 TEL(206) 355-6000 FAX(206) 347-7757 Printed in the U. S.
