Which device can be powered by an external power supply?

• A. BP325
• B. Model 210 Announcer's Console
• C. Model 41 Interface
• D. Studer Vista Console

Answer: (B)

External power supply capability means the device is designed to run from a separate power unit rather than inside the chassis itself. The Model 210 Announcer's Console is built to be powered by an external power supply, a setup common in broadcast environments where the console sits at the desk while the power supply stays in a rack or separate cabinet for stability and heat management. This design lets the console operate from a robust, dedicated PSU outside the main unit. The other devices usually come with their own internal power supplies or rely on a direct AC input, so they aren’t intended to be powered from an external supply in the same way.
