The PPA R19 is a narrow-band, two channel receiver that operates on the 72-76 MHz bandwidth. The narrow
frequency makes it less susceptible to radio interference. And with good fidelity, the R19 is perfect for voice
applications. The PPA R19’s superior dual conversion technology lets you use up to 10 channels simultaneously
with multiple transmitters. The PPA R19 will operate up to 1000 feet coverage (when used with a T35 transmit­ter), and can be used with a variety of earphone, headphone or neckloop options.
