Overview
  • 1Description

The Lectrosonics SRb5P Dual-Channel Slot Mount ENG Receiver Kit with Top Mount BATTSLED from B&H delivers all the standard operating features of the SRb5P with the added convenience of the BATTSLED battery and audio output adapter kit. The BATTSLED installs onto the SRb5P receiver, and allows the receiver to be powered with an NP-F570 slim L series battery for up to 12 hours or two 9 volt batteries for up 5 hours with the optional SR9VBP 9 volt battery adapter (not included).

There are top and bottom mount versions of the BATTSLED, and this version is designed to mount on top of the SRb5P receiver. There are two TA3-M balanced audio outputs at the base.

The receiver itself features two independent digital hybrid wireless UHF receivers in a single lightweight body. The SRb5P provides an additional audio output next to the front panel for use with cameras that have only one audio input in the mounting slot. One channel can feed the connector in the camera slot, and the second channel can be connected to the external audio jack on the camera with a cable. An optional accessory enables you to power the SRb5P Receiver with L and M type rechargeable batteries. With a pair of Lectrosonics transmitters, the SRb5P makes for a formidable wireless solution for the discerning production professional who needs to reliably capture broadcast ready audio.

  • Lectrosonics SRb5P Camera Slot UHF Receiver (Block 19)

    The Lectrosonics SRb5P Camera Slot UHF Receiver (Block 19) is a two-channel slot-mount Digital Hybrid Wireless diversity receiver that supports 486.400 - 511.900 MHz operating frequencies. The SRb5P receiver offers two independent channels and fits into the standard video camera slots found on professional cameras. The two audio channels can feed separate inputs or can be mixed internally to feed a single input. Plus, a DSP compatibility mode allows the SRb5P to be used with Lectrosonics IFB transmitters.

    What makes the SRb5P version different than the SRb is that the SRb5P is intended for use with cameras that do not have both audio channels enabled in the camera slot. So, in addition to the SRb's audio outputs on the rear panel, the SRb5P also features a second set of outputs that are provided through a 5-pin connector on an adapter next to the control panel. This provides audio output from both channels in addition to the camera slot outputs.

    The device's RF performance is extremely stable over a very wide temperature range, making the receiver well suited for the rough environmental conditions found in field production. 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.

    Other features include SmartSquelch for noiseless muting and a built-in spectrum analyzer scans across the tuning range of the receiver to locate RF signals in the vicinity find clear operating frequencies. The two internal receivers can be operated separately, each using switching, antenna combining diversity, or in tandem with ratio diversity reception. Clear frequencies are easily found with the built-in RF spectrum scanner and graphical LCD. The audio outputs of the receivers can be mixed internally, or left separated for discrete recording tracks or external mixing.

    Digital Hybrid Wireless
    Digital Hybrid Wireless is a design that combines digital audio with an analog FM radio link to provide both high audio quality and 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.
    Two Additional Audio Outputs (SRb5P Only)
    The SRb5P is intended for use with cameras that do not have both audio channels enabled in the camera slot. So, in addition to the standard SRb's audio outputs on the rear panel, the SRb5P also features a second set of outputs that are provided through a 5-pin connector on an adapter next to the control panel. This provides audio output from both channels in addition to the camera slot outputs.
    RF Front-End & Mixer
    Each antenna signal is first passed through a high quality SAW filter to reject high power RF signals above and below the operating frequency. A high current amplifier follows the SAW filters and passes the signal to an internal splitter so that both antenna signals are available to both receivers for SmartDiversity reception.
    Smart Noise Reduction (SmartNR)
    The wide dynamic range of digital hybrid technology with a flat response to 20 kHz makes it possible to hear the -120 dBV noise floor in the mic preamp, or the (usually) greater noise from the microphone itself. To put this in perspective, the noise generated by the recommended 4k bias resistor of many electret lavaliere mics is -119 dBV and the noise level of the microphone's electronics is even higher. In order to reduce this noise a Smart Noise Reduction algorithm is used to remove hiss without sacrificing audio high frequency response. The SmartNR algorithm preserves the transparency of the audio signal. Plus, desired high frequency signals are not affected. The SmartNR algorithm has three modes, selectable from a user setup screen. The optimal setting for each application is subjective and selected while simply listening.
    SAW Filters
    The first IF stage at 244 MHz employs two state-of-the-art SAW (surface acoustic wave) filters that increase depth of filtering while preserving sharp skirts, constant group delay and wide bandwidth. This type of filter allows early primary filtering at a high frequency, before high gain is applied, to deliver maximum image rejection. The filters are made of quartz as well, which makes them very temperature stable.
    IF Amplifiers
    After the SAW filter, the 244 MHz IF signal is converted to 250 kHz in receiver 1 and 350 kHz in receiver 2. Only then is the majority of the gain applied, just before the signal is converted to audio. Although these IF frequencies are unconventional in a wide deviation (±75 kHz) system, they offer outstanding AM rejection over a wide range of signal strengths and they support noise improvement at low signal strengths.
    Digital Pulse Counting Detector
    The SRb5P Series receivers use a simple, yet effective digital pulse detector to demodulate the FM signal rather than a conventional quadrature detector. This eliminates thermal drift, improves AM rejection and provides very low audio distortion.
    Supersonic Noise-Based Dynamic Filter & Squelch
    In addition to SmartNR, all hybrid receivers are equipped with a supersonic noise-based dynamic filter and squelch system. The incoming audio is monitored for energy above 22 kHz, pilot tone excepted. Excessive high frequency energy indicates that the received signal is too weak to achieve an acceptable signal-to-noise ratio. Under marginal conditions, a variable low pass filter is rolled in dynamically, masking the noise while preserving as much of the transmitted signal as possible. When the channel is too noisy even for the filter, the audio is squelched. Plus, unlike analog squelching, this noise-based system requires no calibration and there is no better way to track the signal-to-noise ratio than to measure it directly.
    Smart Squelch
    The SRb5P Series receivers are designed to remove distracting noise without the squelching action itself becoming a distraction. They use a technique that waits for a word or syllable to be completed before squelching. Another technique incorporates recent squelching history and recent signal strength, adjusting squelching behavior dynamically for the most serviceable result under variable conditions. Using these and other techniques, the receivers can deliver acceptable audio quality from otherwise unusable signals.
    Talkback Function
    The Talkback function provides a second audio channel separate from the main audio channel to allow the user to communicate with staff and crew. When the button on the housing is pressed, the audio output on the receiver is switched to a different output jack. When the button is released, the audio output returns to the main output jack on the receiver.
    Automatic Power State Restoration
    The firmware "remembers" whether it was turned on or off when power is disconnected and returns to that state when power is restored.
