Configuration DIP Switches

Studio Technologies is sorry to report that the 8 configuration DIP switches had to be placed on the front panel. We tried to place them on the back panel where they’d be hard to reach, or inside the unit where you’d never find them, but we just couldn’t find the space—just kidding! The 8 configuration DIP switches are located on the front panel where you can easily get at them. These switches allow impor- tant operating parameters to be easily configured, and then quickly changed “on-the-fly” as operating requirements dictate. The factory default is to have all 8 switches set to the up position.

A clear plastic “security” cover can be used to prevent access to the configura-

tion DIP switches. One is shipped with each Model 750, being attached to the front panel by means of two screws.

Where the Model 750 is physically located, and who will be operating the unit, will dictate whether the security cover remains in place or is permanently removed. In a facility where many operators have access to the unit, it may be best to set the con- figuration DIP switches to match the needs of most operators, then replace the cover. In a facility where only a few operators have access, such as an SNG vehicle, the cover can stay off to allow quick access to the features.

A brief description of the function of each configuration DIP switch is contained on the front panel, directly above the DIP switches. A more detailed description is provided here:

1. REC/TB AUDIO SOURCE: EXT / INT

This switch selects which audio source will be used by the voice record and talk back sections. In the down position the external audio source is selected. In the up position the internal micro- phone will be used.

Be careful with this switch! In most cases an external audio source will not be connected and the internal microphone needs to be selected for use. It’s easy to accidentally set DIP switch 1 to the down position and have no source of record and talk back audio.

2. REC L+R: DISABLE / ENABLE

This switch selects whether the setup section’s L+R voice segment can be recorded. In the down position recording cannot take place. In the up position recording can take place.

This feature can prove useful where a “semi- permanent” L+R voice segment needs to be re- corded. By placing the switch to the down position, the L+R voice segment cannot be changed.
