Samson RT80 Two-Way Radio User Manual


 
Introduction
We know you don’t like reading owners manuals, but you’ve just purchased one of the most unique
wireless audio products around, and we want to tell you about it! So, before you plug in and start making
music, we’d like to suggest you take just a few moments out to scan these pages. We’ll make it as
painless as possible, we promise—and, who knows, you might just pick up a tip or two.
The Samson Wireless EarAmp® is designed to bring professional in-ear monitoring to a wide range of
users. By eliminating the need for loud onstage “wedge” monitors, it allows you to hear yourself better,
greatly reduces feedback problems, and makes the overall sound coming from the stage significantly
cleaner. You’ll find that this portable, lightweight system provides superlative audio quality and extensive
control at an extremely affordable price. Capable of operating in both stereo and dual mono “2-channel”
mode, the Wireless EarAmp® receiver provides individual volume and balance controls for the best
possible mix, separate bass and treble controls to fine-tune the signal, and a built-in adjustable limiter to
protect your ears. The Wireless EarAmp® transmitter also offers a host of advanced features, including
stereo/mono operation, dual stereo inputs with independent level controls and 15 dB attenuation pads,
dual headphone outputs with dedicated level control, “daisy-chain” input/outputs for routing signal to or
from external devices, a large backlit LCD display and a 5-segment audio VU meter—there’s even
provision for optional computer remote control! Operating in the 614 - 662 MHz range, the Wireless
EarAmp® system is extraordinarily frequency-agile, meaning that it can be used almost anywhere in the
United States, and a unique automatic programming feature allows the receiver to instantly be set to the
same radio frequency as the transmitter, with just the push of a single button.
In these pages, you’ll find an overview of Wireless EarAmp® features, a “Quickstart” (for those of you
with wireless experience), and a guided tour of its various controls. Then we’ll detail how to set up the
Wireless EarAmp® as well as how to adjust it for the best sound quality. Finally, we’ll wrap things up with
reference appendices and full specifications. You’ll also find a warranty card enclosed—please don’t for-
get to fill it out and mail it so that you can receive online technical support and so we can send you updat-
ed information about other Samson products in the future. Also, be sure to check out our website
