Electro-Voice 749 is a high-quality AM tuner designed for background music systems and installations requiring a separate AM tuner. It features a built-in Hi-Q Ferrite loopstick antenna for most locations, but an external antenna can be connected if needed. The Selectivity switch allows for adjustment in areas with inter-station interference. The tuner has a cathode follower, enabling it to be placed at extended distances from the amplifier. Installation is simple, with connections for audio output, external antenna, and ground provided on the rear panel.
