The SRb5P and SRb consists of two separate receivers built into a single, ultra compact housing with adapters for video camera receiver slots and for stand-alone use.
Digital Hybrid Wireless® technology provides superb, compandor-free audio quality and compatibility with other wireless systems. The RF performance is extremely 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 wireless systems and with Lectrosonics IFB transmitters.
Below is a link to the current firmware version for the SRb receiver with the SuperSlot upgrade. This is a zip file, after downloading extract it into a temporary folder. This firmware can only be installed using the SRUSB Firmware Update Adapter accessory item. Use the Wireless Designer program to update firmware. Instructions are found in the SRUSB technical data sheet (coming soon).
Firmware History: SRb Series with SuperSlot
The 5.x firmware series is for SRb units with field modification SRB001 installed (the SuperSlot upgrade).
The SRUSB Firmware Update Adapter is required to update the SRb receiver with the SuperSlot upgrade.
SRb v5.4 – 10 June 2019
- Add new compatibility modes: NU Hybrid, EU Hybrid and 300 Series.
- Add support for frequency block 606 RF boards.
- Improve user interface for selecting compatibility modes and controlling the talkback feature.
SRb v5.3 – 25 January 2016
Added support for new RF boards using LMX2485 PLL (Rev. P). The RF board type is detected at power-on.
SRb v5.2 – 01 October 2015
- Corrected a bug wherein a change to the diversity mode via the UART (slot) caused the LCD to show jumbled pixels until the LCD was refreshed in response to keypad navigation. Now the LCD is refreshed automatically whenever the diversity mode is changed.
- The LCD no longer displays a status message in response to a change to the “locked” parameter via the serial port.
SRb v5.1 – 29 June 2015
Corrected slot power-on voltage threshold.
SRb v5.0 – 05 February 2015
Initial production release.
