DESCRIPTION

The Shure PA821SWB Antenna Combiners actively combine antenna
outputs from up to eight PSM wireless transmitters to a single antenna, im­proving RF performance and reducing rack clutter.

INSTALLATION

Set the power switch on the front panel to OFF before installing. Connect
the unit to an AC power source using the supplied power cable. Switch the
power ON to use the device. The power light will illuminate. Power the unit
OFF when not in use or before disconnecting the unit from the AC power
source.

8-TO-1 COMBINING:

1. Using the supplied BNC-BNC cables, connect the ANTENNA

OUTPUT of each transmitter to the ANTENNA INPUTS of the

PA821SWB (Figure 2).

2. Attach an antenna to the MAIN OUT of PA821SWB. For wideband

applications, use PA805SWB directional antenna (Figure 1).

3. Connect the PA821SWB to a power outlet using one of the supplied

power cables. The PA821SWB contains a universal power supply to
operate anywhere in the world.

NOTE: When the PA821SWB is powered on, the input signal
indicators (1-8) on the front panel will illuminate if an active
transmitter is connected to the corresponding input (1-8) on the
back panel (Figure 1).
