High gain MOSFETs transistors and systematic use of state of the art manufacturing methods, have helped us to find effective solutions for the design this new equipment. The amplifier, of simple and rugged construction, is able to satisfy the requests of all those end-users looking for top-quality equipment at reasonable prices. Main features Weights only 32 Kg, for easy moving and maintenance. Better operation temperature of the equipment, thanks to the air filter placed on the front panel and to the optional air convey to be placed in the rear part of unit. Impressive number of utilities, controls and data, with local or remote record facility. Hi quality/price ratio. Locating main parts and connectors Please make reference of the following pictures in order to locate the main parts of the VHF amplifier. Front Mains part and connectors (front) AC Mains power switch. Allows to switch on/off the whole amplifier Control panel - It’s composed by an alpha LCD display, 5 status LEDs as well as a keypad. The LCD display normally shows the amplifier’s status and another parameter (e.g. power, time, date etc.). The combination between the keypad and the LCD makes easy to provide settings,check measurements etc. Vent grid – from this grid the cooling air is taken in order to keep the proper working temperature. Left front handles – use it in combination to the right handle to move the amplifier Right front handles
