Lectrosonics DSR4 Portable 4-channel Digital Slot Receiver
IMPORTANT!! While we are all very excited about the announcement of the latest technology from Lectrosonics, these units are slowly being shipped out to retail partners.
The DSR4 digital receiver provides the highest level of RF and audio performance available with a versatile feature-set in a compact design for field and location production. Settings can be made from the front panel with tactile buttons and color LCD interface, making the unit ideal for use in portable bag systems and on sound carts. An RF spectrum analyzer and SmartTune are built into the receiver to alleviate interference problems in an increasingly congested RF spectrum.
The mechanical design of the receiver fits into the Super-Slot ecosystem and combines field-proven features developed over many years of experience in motion picture and television production. To decrease weight, the DSR4 provides a four-channel receiver in one unit powered by external DC. The receiver is also equipped with an IR port for data transfer between units. 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 RF gain stages in the front end use a newly developed design to provide low noise RF amplification, excellent sensitivity and extremely low susceptibility to intermodulation and de-sensitization.
The DSR4 offers compatibility with the D-Squared and Duet digital transmitters, including the DBu, DHu, DPr, DBSM, DCHT, and M2T, and backward compatibility with any Digital Hybrid Wireless® transmitters including the SM and SMWB series, WM, HM Series, MM400 Series, HH Series, LT, LMb, UM400 Series, and SSM.
An ideal diversity system constructively combines all the energy available at both antennas. The DSR4 offers two diversity options: for 4-channel operation, each channel combines signals from both antennas in or out of phase, depending on field strength at each antenna and which combination yields the best results. For 2-channel operation, receivers can be paired for Vector Diversity operation. The Vector subsystem smoothly and continuously combines RF signals from both channels, with differing phase angles in order to obtain maximum energy. The four receivers in the DSR4 can be used separately or combined in pairs.
Operating Frequencies (MHz):
- Model A1B1: 470.100 - 614.375
- Model B1C1: 537.600 - 691.175
- 941: 941.525 - 959.825
- 961: 961.100 - 1014.900
- (UK Only)
- Both antenna phase diversity (4 channel operation) or Vector Diversity (2 channel operation) are available for flexibility. It is possible also to have one Vector pair (say, channels 1 & 2) and then two independent antenna phase channels (say, 3 and 4) for a total of 3 channels of independent operation.
- Extremely high IP3 of +15 dBm for high performance in tough RF environments
- Built-in TA5M connector on faceplate for channels 3 & 4 external audio outputs
- Color display
- Tactile buttons
