The Blonder Tongue AM Series includes professional quality, agile audio/video modulators equipped with the Emergency Alert System (EAS) feature, which can also be used as an alternate IF input. These units provide audio and video modulated RF carrier on any channel in the 54 to 550/750 MHz frequency range. The Blonder Tongue AM Series is ideal for placing audio and video onto any unused channel (broadcast and CATV, including HRC and IRC assignments). Any standard audio/video source can be used, such as satellite receivers, television cameras, video tape recorders, or television demodulators. Agile channel selection permits on-the-fly channel changes and reduces the need for large inventories of channelized products. These modulators have a wide range of standard and optional features that make them very suitable for advanced CATV systems.
