Wireless EarAmp® System Features
The Samson Wireless EarAmp® system utilizes state-of-the-art technology in personal monitoring.
Its main features include:
Excellent audio quality, with superior frequency response and low distortion.
An extraordinary degree of frequency agility. The operating frequency can be selected either by
Group and Channel (there are 8 Groups of 16 Channels each) or by direct frequency selection (in
25 kHz increments between 614.35 and 662.0 MHz). This makes the Wireless EarAmp® eminently
suitable for traveling performances and allows it to be used in even the most “RF-hostile” urban
environments.
Group numbers correspond to U.S. TV channel numbers so it is easy to select a known vacant
channel.
Any number of receivers can be used with a single transmitter.
Unique automatic receiver program function allows RF resetting at the push of a single button.
PLL synthesized technology minimizes spurious emissions and provides solid, stable performance.
Convenient belt clip for and flesh-colored ear buds for unobtrusive, nearly “invisible” usage.
Receiver offers dedicated volume and center detented balance controls, along with independent bass
and treble controls allow each user to set up the optimum in-ear mix. There’s even a Loudness
switch for improved legibility when operating at low signal levels.
Receiver provides stereo and dual mono (“2 CH”) modes for maximum flexibility. In “2 CH” mode, the
balance control enables you to adjust the blend of the two incoming signals, which are mixed internal-
ly to mono and routed to both ear buds.
Receiver has a high-powered 200 mW 1/8" (Walkman-type) headphone output, while the transmitter
offers dual 1/4" and 1/8" (Walkman-type) headphone jacks.
Built-in adjustable limiter helps protect your ears from transients and signal overloads.
Receiver utilizes microprocessor true diversity for maximum range, tone key squelch for rejection of
spurious signals, and noise reduction for crystal-clear sound.
Receiver operates on a standard 9-volt battery, with battery life of four hours or more.*
Battery LED indicator shows you when the receiver battery needs to be replaced.
Unique “daisy-chain” parallel inputs/outputs allow a third signal source to be input or external
monitoring of incoming audio signal to the transmitter.
Transmitter operates in stereo or mono mode, and provides dual inputs (Main and Aux), with
independently adjustable input level for each, as well as a five-segment input level VU meter to allow
optimum gain settings. In addition, a large back-lit LCD display also shows the currently selected
Group/Channel and radio frequency.
Switchable 15 dB pad for main and auxiliary inputs allows the Wireless EarAmp® system to be used
with a wide variety of signal sources.
Transmitter is rack-mountable in any standard 19" rack (taking only a single space) for portability and
easy integration into existing systems.
Computer interface allows optional remote control of all transmitter functions via software.
Rugged construction of all components makes the Wireless EarAmp® eminently roadworthy.
* Typical usage. Actual battery life may vary depending upon headphone output level.
