The Lectrosonics DSR is a lightweight two-channel digital slot receiver engineered for mobile sound production, sports video, reality TV, and anywhere a wireless system must provide mission-critical signal stability and clear, transparent 24-bit / 48 kHz sound. It is compatible with the company's mono digital transmitters (DBSM, DBu, DHu, DPR, DPR-A) and stereo digital transmitters (DCHT, M2T), and backward compatible with any Digital Hybrid Wireless transmitter.

The DSR provides two independent receiver channels at the highest level of RF and audio performance available—versatile field-proven feature set, selectable AES3 or analog mic-/line-level outputs, and next-generation capabilities in the Unislot/Superslot form factor—for ENG, field, and location production. Settings can be made from the front panel with tactile buttons and a color LCD interface, making the unit ideal for use in portable bag systems, mounted in or on cameras, and on sound carts. The built-in RF spectrum analyzer and SmartTune function help you quickly find a clean frequency to alleviate interference problems in an increasingly congested RF spectrum.

• The mechanical design of the DSR fits into the Superslot ecosystem and combines field-proven features developed over many years of experience in motion picture and television production. To decrease weight, the DSR packs two channel receivers in one unit powered by external DC.
• The 2-way IR sync makes quick work of setting up matching transmitters.
• The machined aluminum housing and panels are surfaced with a hard-anodized finish with laser etched markings to withstand the rigors of field production.

• The DSR's Vector Diversity subsystem smoothly and continuously combines RF signals from two receiver front ends per channel, with differing phase angles in order to obtain maximum energy. Not only does this method deliver clean, artifact-free performance in all modes, it is actually able to take two signals compromised by multipath interference and reassemble them into a usable signal.
• The two RF gain stages in the front end of each audio channel provide low-noise RF amplification, excellent sensitivity, and extremely low susceptibility to intermodulation and desensitization.

• The DSR offers one of the highest Third-Order (IP3) performances at +11 dBm, compared with +5 to +8 dBm provided by typical audio RF receivers. High IP3 performance allows the receiver to better eliminate the negative impact caused by third-order intermodulation artifacts and have a better signal-to-noise ratio, more reliably in today's tough RF environments.

• SmartTune is the easiest and fastest way to scan the local RF spectrum and find clear operating frequencies. The receiver scans through its tuning bandwidth and automatically finds empty areas within the tuning range that have little or no RF energy. The receiver will then set itself to a frequency within an empty area and prompt you to continue or use the IR function to sync to a transmitter.

• With a noise floor at -120 dBV and a frequency response up to 20 kHz, high-frequency noise in the source audio is more apparent than in conventional wireless systems. The SmartNR algorithm has three modes. When Off, no noise reduction is performed. When Normal is selected, enough noise reduction is applied to remove most of the hiss from the mic preamp and some of the hiss from lavalier microphones. When Full is selected, enough noise reduction is applied to remove most of the hiss from nearly any signal source of reasonable quality, assuming levels are set correctly at the transmitter.

• The DSR offers compatibility with the D-Squared and Duet digital transmitters, including the DBu, DHu, DPr, DCHT, DBSM, and M2T.
• There is backward compatibility with any Digital Hybrid wireless transmitters including the SM and SMWB series, WM, HM Series, MM400 Series, HHSeries, LT, LMb, UM400 Series, and SSM.

Related Questions and Answers

Q: 1. Does this work for both channels in a Sony X400 camera?

A: Hi Tom, Yes. Thanks, Erin

Q: 2. What alternatives do i have to power this unit when in a sound bag?

A: The Sony URX-S03D UWP-D Dual-Channel Slot-In Wireless Receiver requires 7V DC 200mA from a camcorder or wireless power adapter such as the Sony DWA-F01D Digital Wireless Adapter (B&H # SODWAF01D). For mixer-bag use with battery systems, centralized management for the DWA-F01D can be achieved using the Hirose 4-pin or BP jack. For AC powering, you can use an InfoLITHIUM battery charger as an AC adapter or use a conventional AC adapter with the BP jack.

Q: 3. Does this receiver fit the F5 Documentary Dock?

A: Yes it matches the 15-pin Sub-D connector.

Q: 4. Will the URX-S03D fit into the PXW-X320 XDCAM? if so, do you need a mounting adapter? thx

A: Based on Sony's website, this device should fit right into the PXW-X320's slot without any additional adapters.

Q: 5. Is this compatible with older Lectro transmitters (e.g. UM400a)?

A: Yes, the Lectrosonics SRc Dual-Channel Slot-Mount ENG Receiver can be used with older Lectrosonics transmitters that operate on the same frequency band. The receiver has different compatibility mode settings for use with transmitters other than those from the Lectrosonics Digital Hybrid Wireless series.

Q: 6. What is the power input? What kind of cable could I use to go from an NP-1 or BDS into the SRc?

A: The receiver accepts from 6-18V d.c. @1.4W, so it is compatible with most any battery or DC supply system. The connector is an LZR threaded locking plug. Our PS200 cable goes from a Hirose to LZR so that might help. (You didn't state what type of connector is at the supply side). Also - and very important: you must order with the receiver a bottom plate that is suitable to your application. If the receiver is not being used in a camera the most commonly used plate is the SREXT. This gives you both audio channels out on TA3 connectors and the LZR power input port.

Q: 7. Is this transmitter SuperSlot compatible?

A: No, the Sony URX-S03D UWP-D Dual-Channel Slot-In Wireless Receiver does not use a SuperSlot compatible form factor. The URX-S03D provides a two-channel digital connection to XDCAM camcorders, or a single-channel connection to HDCAM camcorders via a D-sub 15-pin interface.

Q: 8. Will this connect to my old UM200C transmitter?

A: No, this receiver is not compatible with the UM200C transmitter. The UM200C can be used with any 200 Series Lectrosonics receiver that operates within the same frequency group. The DCR822 receiver is compatible with D-Squared and Duet digital transmitters, including the DBu, DHu, DPr, DCHT, and M2T. There is backward compatibility with any Digital Hybrid wireless transmitters including the SM and SMWB series, WM, HM Series, MM400 Series, HHSeries, LT, LMb, UM400 Series, and SSM.

Q: 9. Would this receiver work with a Sennhesier SK500 transmitter in thr Aw+ band (470-558Mhz)?

A: No it would not work with Sennheiser transmitters. It can be used to capture audio when paired with the SONY UTX-B03HR beltpack transmitter & microphone (sold separately)

Q: 10. Can the URX-S03D receiver work with the UTX-B40 or UTX-B03 transmitters? Thank you

A: This is compatible with the UTX-B03HR, not the UTX-B03
