The ST-FS6 is used in applications where an excessive RF level is induced in the audio cables producing audio interference in the system. It is not necessary to use all 6 input/ output channels, and wiring configurations may vary according to the application. For example, INPUTS 1 and 2 may be used to suppress a single pair while the shield for that pair is connected to ground. In other installations, it may be desired to also ferrite suppress the shield. In this instance, 1 and 2 may be used for signal and INPUT 3 used for the shield. The ST-FS6 may be used with shielded or unshielded audio cables. With shielded cables, the best RF suppression is often achieved by suppressing the signal conductors while tying the shield to ground (either earth or rack). For such installations, the ST-FS6 provides two ground screw terminals for shield connection. These two terminals are not internally connected in the module. They serve as a tie point for connecting shields to ground. These terminals are not used when unshielded cable is being suppressed.

The ST-FS6 module is a passive device with six identical channels. All inputs are fed through a series of ferrite RF suppressors to their respective outputs. All channels are isolated from each other so that any connection scheme may be used to suit an installation.

STICK-ON SERIES

STICK-ONs are the original application-specific modules for the A/V, recording and broadcast industries. Module functions include signal detection, switching, pre-amplification, format conversion, line driving, power amplification, mixing, distribution, gain control, equalization, routing and more. Each STICK-ON is an ultra-compact module engineered to provide higher performance and longer life than other industry products. STICK-ON modules are solid encapsulated hybrid circuits in durable industrial black plastic enclosures (1.55", 3.94 cm x 3", 7.62 cm x 0.65", 1.65 cm) with clear bold white lettering for the terminal block connections, recessed trimming controls and switches.

Since RDL first originated application-specific modules, STICK-ONs have led the industry in economical, high-performance and cost-effective long life solutions in system designs. Multiple STICK-ON modules can be interconnected to form all or part of an A/V system. A single STICK-ON module may be mounted right where its function is needed, often to add an input, output, or gain adjustment to existing equipment. STICK-ON modules allow customizing an A/V system to precisely match users’ needs. Adding STICK-ONs to an existing system can extend system life by adding updated features, resulting in considerable cost savings. A complete range of backboard and rack mounting options is available for systems comprised of multiple STICK-ON modules.

The technology used in STICK-ON modules has been regularly updated over the years to insure industry-leading performance. Functions and features provided by STICK-ONs, since their introduction, are still available today. This continuity in product offering and support makes STICK-ON modules the preferred long-term resource for system design solutions. STICK-ON SERIES modules are designed and manufactured in the U.S.A.
