The PR-72b Companion receiver is a high performance miniature receiver. And due to its excellent performance and many available options, this versatile receiver may be used for many applications — IFB and professional studio communications, personal cueing, industrial communications, and individual auditory assistance, to name a few. Also, because of its extended frequency response and low noise level, the PR-72b is a convenient receiver to use with portable tape recorders.
The PR-72b incorporates the latest state-of-the-art technology offering low power consumption for longer battery life (up to 40 hours). Special features include an LED battery condition indicator, automatic on/off power switch, battery charging access through the output jack, slide-open battery compartment, and no external antenna — only the output cable extends from the receiver.
The following options are also available: plug-in channel selector, external microphone input for specialty applications, switch for two-channel operation and an independent on/off switch. Moreover, the PR-72's small size and light weight make it easy to carry in a pocket or pouch.
