Lectrosonics DSR4 Four Channel digital receiver 537.600-691.175 MHz
Lectrosonics DSR4 Four Channel digital receiver 537.600-691.175 MHz
The DSR4 digital receiver ( DSR4-B1C1 ) 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.

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: +15 dBm
Diversity method: Antenna phase switching (4 channel operation)
Vector diversity (2 channel operation)
Antenna inputs: 50 Ohm; SMA female connectors
Audio output connectors: • Interchangeable D connector adapters
or camera slot interfaces
• Dual TA5 male (mini XLR) balanced
output adapter
• Battery sled adapters with TA5 male
outputs.
• Front panel TA5 male for AES3 outputs or
. analog output channels 3 and 4.
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.
