Description

You can rely on the Lectrosonics UMCWB 537-768MHz UHF Antenna Multi Coupler, a high-quality and durable solution designed to enhance the performance of your UCR195D/UCR200D/UCR205D/UCR210D/UCR211/UCR300/UCR310/UCR411A receivers. This advanced and innovative device is specifically engineered to deal with changing RF environments and is ideal for mobile productions spanning broad geographic areas.The UMCWB Multi Coupler features a robust mechanical rack mount that conveniently houses four diversity compact receivers in a single rack space. It offers a wide frequency coverage, with the standard version covering frequency blocks from 21 through 29, and the wideband low version covering frequency blocks from 470 through 26. This reliable multi coupler is designed to preserve the sensitivity and overload performance of top-tier receivers. It incorporates selective filtering in the front end to attenuate RF signals above and below the passband, effectively suppressing intermodulation and noise. Following the filters, a low noise RF amplifier with gain is included to compensate for the losses in the splitter. The precision strip line splitter/isolator then divides the RF signal into four isolated signals, preventing any spurious RF coupling between receivers. This termination-independent design ensures that mismatched or disconnected RF outputs won't affect the performance of other receivers. The UMCWB Multi Coupler operates on an external power source of 11 to 18 VDC, with individual auto-reset fuses for each receiver in the RF/power distribution module. This design eliminates potential ground loops and AC hum that can occur when the receiver outputs are connected to other audio equipment operating from a different AC source. The antenna input features standard 50 ohm BNC connectors for both the antenna inputs and signal distribution. The RF signals are fed to the receivers via coaxial cables that loop through the front panel to the receiver inputs. The leads are labeled as "A" and "B" and routed so that each receiver has one of each connected for diversity reception. The multi-coupler is powered by an external 12 VDC (11 to 18 VDC is acceptable), with the power supply capable of handling up to 2 amps of current. DC power is distributed to the receivers via rear panel pigtail connectors. The Lectrosonics PS70 is a switching power supply with a coaxial connector matched to the 12VDC power jack on the multicoupler. The AC receptacle is a standard, grounded IEC 60320 C14 inlet socket that will accept common cords like those used on computer equipment (AC cord is not included). The output cable is 6' long. In summary, the Lectrosonics UMCWB 537-768MHz UHF Antenna Multi Coupler is a reliable, high-quality solution that ensures optimal performance and compatibility with your UCR series receivers.
