StudioTech 233 manual Configuration, Pushbutton Labeling

Pushbutton Labeling

The three pushbutton switches used in the Model 233 were selected for several reasons. Foremost was the fact that they are highly reliable, using gold-plated con- tacts for long life in less-than-ideal environ- ments. A second reason was that applying customized labels to the button caps would be very simple. The labels, text printed on clear material, are placed under the clear caps on the top of the buttons.

From the factory the left button is labeled COUGH, the center button is labeled TALKBACK 1, and the right button is labeled TALKBACK 2. This was selected to be appropriate for many on-air applica- tions in English-speaking locations. But it’s expected that these may need to be changed to meet the needs of specific applications.

As a “head start” for some applications, a clear sheet with a number of commonly used button designations printed on it is included in the shipping carton. These were created at the factory using a stan- dard personal computer graphics program and laser printed onto 3M CG3300 trans- parency film. The desired button labels can be cut out with a pair of scissors, fol- lowing the printed guide lines that indicate the required size.

The clear lens on top of each button cap can be removed with a fingernail or small screwdriver. Be certain not to scratch the button if a screwdriver or other small tool is used. The clear label can be removed and replaced. The button cap is then snapped back into the top of the button housing using finger-pressure only. No tool is required to replace the button cap.

If you need to make your own labels the process is quite simple. Use a personal

computer to create the desired text. The finished label size should be 0.625-inches (15.8 mm) square. The completed artwork can then be printed on transparency film sheets using a laser or inkjet printer. These sheets are readily available from most office supply stores. A pair of scissors or an X-ACTO® knife will complete the task.

Configuration

For the Model 233 to support the needs of specific applications a number of operating parameters must be configured. These include microphone preamplifier gain, phantom power on/off, headphone source and output mode selection, and operating modes. One 12-position and three 8-position DIP-type switch assemblies are used to establish the desired configura- tion. These switch assemblies are referred to as SW1 through SW4, with individual switches designated as SW1-1, SW1-2, etc. The switch assemblies are accessed through openings in the bottom of the Model 233’s enclosure. The enclosure does not have to be disassembled to gain access to the switches.

To prevent unauthorized personnel from changing the configuration settings, a se- curity plate is attached to the bottom of the Model 233’s enclosure. For convenience, attached to the security plate is a configura- tion settings label. It provides a summary of the configurable parameters and related information. Refer to Appendix A for a representative view of the label. The secu- rity plate is held in place by means of four rubber bumpers (“feet”) that have built-in screws. Using your fingers, remove the four bumpers so that the plate can be removed. Refer to Figure 3 for a detailed view of the configuration switch assemblies.
