Digital Hybrid Wireless technology provides superb, compandor-free audio quality and compatibility with other wireless systems. The RF performance is extreme- ly stable over a very wide temperature range, making the receiver perfectly suited to the rough environmental conditions found in field production.
A DSP compatibility mode allows the receiver to be used with a variety of Lectrosonics and other brands of wire- less systems and with Lectrosonics IFB transmitters.
The front panel features a menu-driven LCD interface and four membrane switches which are used to view and alter settings. The main LCD window displays the pilot tone indicator, diversity activity, RF level, audio level and transmitter battery status for both receivers. To find clear operating frequencies, a built-in spectrum analyzer scans across the tuning range of the receiver and dis- plays a histogram of RF activity within the tuning range. Areas of little or no RF activity are easily recognizable.
The two internal receivers can be operated separately, each using switching, antenna combining diversity, or in tandem with ratio diversity reception. The audio outputs of the receivers can be mixed internally, or left separated for discrete recording tracks or external mixing.
A variety of output adapters and mounting options are available for camera slot operation. On the SRb5P, a 5-pin connector next to the control panel provides audio output from both channels in addition to the camera slot outputs. The unit is powered from an external 6 to 18 volt DC source.
Digital Hybrid Wireless is a revolutionary design that combines digital audio with an analog FM radio link to provide both outstanding audio quality and exemplary, noise-free RF performance.
Using a patented algorithm to encode 24-bit digital audio information in the transmitter into an analog format, the encoded signal is then transmitted over an analog FM wireless link.
At the receiver, the signal is then decoded to restore the original digital audio. This process eliminates compandor artifacts and produces an audio frequency response flat to 20 kHz.
Tuning range A1: 470.100 - 537.575 MHz
Tuning range B1: 537.600 - 614.375 MHz
Tuning range C1: 614.400 - 691.175 MHz
Adapter kit for SR receiver, two TA3 audio output jacks, locking power connector, includes 6' power cord. Has spare mounting screws in dummy holes in adapter.
LT (B1: 537.600 - 614.375 MHz, BLOCKS 21, 22, 23)
LT transmitter is compatible with all Digital Hybrid Wireless receivers and even some from other manufacturers, making it comfortable in a wide variety of applications from video production to theater, stage and house of worship.
The LT can be configured to operate as a "one touch" device with a single power on/off switch on the top panel, or with full access to all operational parameters using the side panel membrane switches and LCD interface. The top panel switch can also be configured to provide a mute or talkback function.
