Lectrosonics DSR Two Channel Digital Slot Receiver Band 941 covers Frequency 941.525 - 959.825

The DSR and DSR5P digital receivers provide the highest level of RF and audio performance available with a versatile feature set in a compact design for camera mounted applications. Settings can be made from the front panel, making the unit ideal for use in camera hop configurations, in bags and on sound carts. An RF spectrum analyzer and SmartTune are built into the receivers to alleviate interference problems in an increasingly congested RF spectrum.

The mechanical design of the receivers 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/DSR5P provide a two channel receiver in one unit powered by external DC. The receivers are 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.
