Rolls

The ROLLS HR78 is a PLL synthesized digital AM/FM tuner in a feature-packed half-rack chassis. The unit is ideal for replacing analog tuners, and where a small digital tuner is desired. The unit ships with FM and AM antennas, and the 1/8" output has sufficient levels to drive a pair of headphones. Up to two HR78 units may be rack mounted in a single standard 1U rack space, the Rolls URT5 (Universal Rack Tray), or the RMS270 Rack Module System.
