Rolls HR78 AM/FM Digital Tuner (Discontinued)

Description

Details

The Rolls HR78 has been replaced with the Rolls HR78X.

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.
