Alcad Masthead Amplifier – 2 inputs – 20dB Gain

The series of AM amplifiers 2 input broadband home amplifiers. Individual inputs have separate output level regulation. The +12V amplifier is powered remotely via a coaxial cable through the output. The original power supplies are AL-105 or AL-205, which include a power bypass and have an integrated broadband splitter. Amplifiers produced by SMT technology are placed in a Zamac casting, which is protected against weather conditions by a new, more durable plastic cover. Inputs and outputs are on F-connectors. The plastic cover of the amplifier is suitable for both mounting on a mast (using the included clamp) and on a wall. For selected inputs, +12V/50 mA is supplied via the power switch for the preamplifiers.
