The UMCWB-D provides a mechanical rack mount with power and RF signal distribution for any four DCR822, DSR, DSR4, UC411, or SR units compact receivers in a single rack space. No audio connections are provided – these would come from the backs of the receivers using “EXT” type back plates (not included). External antenna lines are connected via standard 50 ohm BNC. The UMCWBD-L does not provide antenna power nor does it offer antenna loop-through connectors. A thread locking DC jack accepts power in from the included DCR15/4AU power supply.
Interchangable insert flanges (available as separate kits) allow you to use any combination of recievers and easily change them out as necessary.
The RF multicoupler preserves the sensitivity and overload performance of the finest receivers. Selective filtering in the front end attenuates RF signals above and below the passband to suppress intermodulation and noise. Following the filters is a low noise RF amplifier with gain matched to compensate for the losses in the splitter that follows.
A precision strip line splitter/isolator divides the RF signal into four isolated signals preventing spurious RF coupling between receivers. The splitter/isolator is termination independent which prevents mismatched or disconnected RF outputs from affecting the other receivers.
The assembly is powered from an external source of 11 to 18 VDC with individual auto-reset fuses for each receiver in the RF/power distribution module. This architecture eliminates ground loops and AC hum that can occur when the receiver outputs are connected to other audio equipment operating from a different AC source.
