External Power - PSC Active RF Matrix Rack Manual

EXTERNAL POWER:

This unit can be powered from AC Line Voltage (90 to 240Vac) or from low voltage DC such as
rechargeable batteries, DC power supplies or other sources. The DC input has a voltage range
of 10 to 18Vdc. The unit draws approximately 800mA of current @ 12Vdc with no active
antennas powered up. When operated with the maximum of eight (8) active, powered
antennas, the unit will draw approximately 2 Amps @12Vdc.
DC Input on 4 Pin XLR, AC Input
RF CIRCUITY DECRIPTION:
Your new PSC Active RF Matrix Rack contains RF distribution designed to provide proper, clean
RF distribution to your receivers. Each of the four (4) diversity RF inputs contains a built in DC
bias circuit designed to be able to power external remote powered antennas and/or remote RF
amplifiers and also super high quality RF switches that allow those individual RF input pairs to be
assigned or not assigned to the RF mix. These high-quality RF switches provide more than 50dB
of RF isolation when switched off. Each diversity RF section is summed using high quality RF
combiners with typical rejection ratios of better than 27dB. An RF bandpass filter (various
frequency ranges available) follows the RF combiner and is then followed by an RF limiter to help
guard against RF overload. Two, very low noise, high current RF Amplifiers, and two RF splitters.
Are used to feed the 16 SMA RF outputs. Each part of the RF circuitry also contains its own,
dedicated power regulation circuit for better RF cross talk specifications. The circuit boards used
in this product are special, 4-layer RF PCBs for maximum performance.
