PSC RF Multi SR Six Pack
The PSC RF Multi SR Six Pack contains two separate, active 1 x 4 RF splitters for use with up to
three slot style receivers. This compact, rugged device was developed using the latest super
low noise RF amplifiers and will operate over an extended frequency range of 470Mhz to
700Mhz.
Its two inputs are traditional BNC connectors for ease of use in interfacing with your external
antennas. Each of the SMA outputs offers a typical isolation factor of 24 to 28dB between
radio receivers. The PSC RF Multi SR Six Pack also has the ability to power external powered
antennas or remote line amplifiers. There are two front panel mounted switches on the unit.
One is marked “MAIN POWER” and this controls the overall power to the unit. The second
switch is marked “ANT PWR” and this switch controls the power being sent to an external
powered antenna or remote line amplifier. Both switches light up when in use. The entire
unit is powered from any source of external DC power of 12Vdc @ approximately 170 to
210mA. On the left side of the unit there are six TA3M mini XLR output connectors. These
provide audio output from the three slot receivers. In addition, there are two chassis

mounted SMA connectors on the left side panel of the unit. These offer two additional RF
outputs that can be used to feed another PSC RF Multi SR Six Pack or PSC RF Multi SMA or
other similar device.
The PSC RF Multi Six Pack is equipped with two mounting holes for use in mounting the Six
Pack to Sound Devices 664 and 688. These two screw holes line up with the factory screws on
the Sound Devices units. This allows you to mechanically secure the Six Pack to your Sound
Devices 664 or 688. See photo below.
