Features

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 hardanodized 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.

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

NOTE: It’s the user’s responsibility to select the approved frequencies for the region where the transmitter
is operating.

  • Frequency Selection Steps: 25 kHz
  • Frequency Stability: ±0.001 %
  • Front end bandwidth: ±5.5 MHz, @ -3 dB
  • Sensitivity: 20 dB Sinad: 0.9 uV(-108 dBm), A weighted
  • 60 dB Quieting: 1.12 uV (-105 dBm), A weighted
  • AM rejection: >60 dB, 2 uV to 1 Volt
  • Modulation acceptance: 85 kHz
  • Spurious rejection: 85 dB
  • Third order intercept: +11 dBm
  • Diversity method: Vector diversity
  • Antenna inputs: 50 Ohm; SMA female connectors

Audio output connectors:

  • Interchangeable D connector adapters or camera slot interfaces
  • Dual TA3 male (mini XLR) balanced output adapter
  • Battery sled adapters with TA3 male outputs

Front panel output:

  • Control panel TA5M with two balanced outputs (5P model) (either analog or AES3)

Audio Performance (overall system):

  • Frequency Response: 25 Hz to 20 kHz (+0/-3 dB)
  • THD: 0.2% (typical)

SNR at receiver output (dB):

Note: The dual envelope “soft” limiter provides exceptionally good handling of transients using variable attack and release time constants. Once activated, the limiter compresses 30+ dB of transmitter input range into 4.5 dB of receiver output range, thus reducing the measured figure for SNR without limiting by 4.5 dB.

SmartNR No Limiting w/Limiting
