FUNCTIONS:A.

1 X 8 ACTIVE SPLITTERS

The PSC RF Multi Dual 1 x 8 contains two independent 1 x 8 active splitters. Each ofthese 1 x 8 active splitters contain a very low noise amplifier, a high pass filter and an 8way splitter providing a low noise signal splitting function without loss and with a highdegree of isolation between the signals of your wireless receivers. Because the devices
are active, they cannot be used as combiners. You must only feed an RF signal into thesingle BNC connector labeled with a letter such as “A” or “B”, This signal will then be
amplified and split up 8-ways and feed to the corresponding 8 output BNC connectors.
These connectors are then connected to the wireless receivers. The 1 x 8 active
splitters can be daisy-chained for special applications.

A. DC POWER, 4PIN XLRThe PSC RF Multi Dual 1 x 8 can be powered from DC for ease of use in the field. TheRF Multi Dual 1 x 8 Is designed to operate off any DC voltage within the range of 9 to 18
VDC. To power the RF Multi Dual 1 x 8 in this way, you simply have to plug in a 4-pin
XLR power cable from your battery. In keeping with industry standards, Pin 1 is Groundand Pin 4 is Positive. Because the RF Multi Dual 1 x 8 is reverse-polarity protected, if
you inadvertently miss-wire your power cable, no damage will be done, the RF Multi
Dual 1 x 8 simply will not power up. The PSC RF Multi Dual 1 x 8 contains a DC to DC
converter that allows it to operate over wide range of input voltage without difficulty. At acommon voltage of 12Vdc, the RF Multi Dual 1 x 8 consumes approximately 160mA..
Current is inversely proportional to the operating voltage. For example: at 10Vdc thecurrent consumption is 230mA, at 18Vdc the current consumption is 115mA.

B. AC POWER, MAINS
The PSC RF Multi Dual 1 x 8 can also be operated from AC mains. The AC input
voltage range is 100Vac to 240 Vac, 50 to 60Hz. This allows the RF Multi Dual 1 x 8 tooperate worldwide without adjustment or jumper setting. Power consumption isapproximately 15 watts when operated from AC mains.

CONSTRUCTIONA.

CHASSISThe chassis of the RF Multi Dual 1 x 8 is made from formed steel and an aluminum faceplate. The chassis is painted with a textured finish black paint and the aluminum front
panel is anodized black for a professional appearance. The case occupies two rack
spaces and can be installed in all standard racks.
B.

ELECTRONIC TOPOLOGY

The circuitry within the RF Multi Dual 1 x 8 has been designed to provide years oftrouble free use under normal operating conditions. The DC power supply is reverse
polarity protected and the AC supply is designed for wide input range use. The internal
voltage regulation is designed for quite, trouble free operation and all of the BNC inputs
and outputs are DC protected.
C.

ENVIRONMENTAL OPERATIONThe PSC RF Multi Dual 1 x 8 can operate over a temperature range of –4F to +158 F (20C to +70C).
