This half-rack chassis supports up to 90 m (300 ft) of wireless operation and can be permanently mounted with a rackmount kit (sold separately). The receiver uses True Diversity to minimize dropouts, 1/4-wave antennas, and multi-segment LED meters for AF and RF levels. It provides balanced XLR and unbalanced 1/4" outputs with a Mic/Line level output switch. Supplied at 12 V ±10% and 160 mA.
