Application
The CA-311 amplifier is used to amplify and distribute TV and FM radio signals. It is a brand-name device designed for the use in small and medium size community installations. The CA-311 is equipped with two band inputs and two outputs. This model fills up the gap among CA-210, CA-215, AI-200 and CF-512 amplifiers.
Installation and security notice for amplifier's users
The amplifier is fed from its internal stabilized power supply, which is powered directly from the mains. It is not designed for the use in open spaces. It cannot be installed in wet conditions or near heaters and similar equipment. The unit requires natural ventilation, so it must not be covered by any objects. It ought not to be connected to the mains until all connections within an antenna installation have been properly made. The amplifier has the option of feeding preamplifiers with 24 V voltage, and maximum current of 50 mA through the UHF input. Preamplifier's feeding is switched on automatically as soon as the preamp is detected.
The unused main output must be closed with a 75 ohm resistor, such as R66200.
