Lectrosonics R400A-19


UHF Table-Top Receiver, Venue-400 Series Block 25

BSW PART: R400A-19

Lectrosonics R400A-19
The R400A is a high performance, triple-conversion, frequency synthesized tabletop UHF receiver fully compatible with all Lectrosonics 400 Series Digital Hybrid Wireless* transmitters, 200 Series and 100 Series analog transmitters and IFB transmitters, plus some analog transmitters from other manufacturers. It features 256 user selectable frequencies, and its proprietary audio processing includes a digital signal processor (DSP) for very low distortion, a superior signal to noise ratio and two independent audio outputs, one balanced XLR and one unbalanced 1/4-inch jack.

It boasts 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.

The R400A is available in various frequency blocks. This is Block 25 (640-665 MHz).

*Digital Hybrid Wireless is a revolutionary new design that combines digital audio with an analog FM radio link to provide outstanding audio quality and the exemplary RF performance of the finest analog wireless systems. This overcomes channel noise in a dramatically new way, digitally encoding the audio in the transmitter and decoding it in the receiver, yet still sending the encoded information via an analog FM wireless link. This proprietary algorithm is not a digital implementation of an analog compandor. Instead, it is a technique that can be accomplished only in the digital domain. The process eliminates compandor artifacts, expanding the applications to include test and measurement of acoustic spaces and musical instruments.

CONSUMER ALERT

Most users do not need a license to operate this wireless microphone system. Nevertheless, operating this microphone system without a license is subject to certain restrictions: the system may not cause harmful interference; it must operate at a low power level (not in excess of 50 milliwatts); and it has no protection from interference received from any other device.

Purchasers should also be aware that the FCC is currently evaluating use of wireless microphone systems, and these rules are subject to change. For more information, call the FCC at 1-888-CALL-FCC (TTY: 1-888-TELL-FCC) or visit the FCC’s wireless microphone website at www.fcc.gov/cgb/wirelessmicrophones
