The R400a is a high performance, triple-conversion, frequency synthesized,
UHF receiver fully compatible with all Lectrosonics 400 series transmitters,
and a number of analog models. The proprietary audio processing includes a DSP
(digital signal processor) for very low distortion and a superior signal to
noise ratio. The DSP eliminates a compandor and its artifacts to provide
exceptional audio quality when operating in its native hybrid mode. Special DSP
algorithms also provide compatibility modes for use with Lectrosonics 100 and
200 Series analog transmitters.
The R400a features a powerful menu-driven LCD graphic
display operated with a push-button switch and a dual function rotary encoder
control as a convenient means of viewing and altering settings. The LCD main
window displays the pilot tone indicator, diversity antenna activity, RF and
audio levels, operating frequency, transmitter frequency switch settings and
transmitter battery status. Settings can be changed using the MENU functions. A
built-in RF spectrum analyzer is included to conduct site surveys to find
interference-free operating frequencies. The analyzer quickly tunes the
receiver across its 256 frequencies and records a marker on the LCD indicating
the strength of any RF signals picked up. Within less than a minute, a complete
display is generated showing the RF activity across the entire tuning range of
the receiver. An area with little or no RF activity is then easy to locate and
select.
