The Ectron Model 778 Wideband Amplifier/Conditioner is an ac-line-powered, all-solid-state, high-performance, direct-coupled, wideband differential dc amplifier with transducer conditioning and filtering capabilities. Among its features are excellent linearity, stability, low noise, extremely fast overload recovery, and unique high-frequency common-mode rejection. Specifically designed to process wide band low-level signals, the Model 778 is ideally suited for use wherever wide bandwidth, high-frequency common-mode rejection, and outstanding overload recovery are required. Up to ten Model 778 Amplifiers mount in the Model R718 19-inch rack-mount enclosure. Each amplifier has quick-disconnect rear-panel connectors for all inputs, outputs, and power.
