DESCRIPTION

The Shure PA821A 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 PA821A
(Figure 2).

2. Attach an antenna to the MAIN Out of PA821A. For wideband
applications, use PA805SWB directional antenna (Figure 1).

3. Connect the PA821A to a power outlet using one of the supplied
power cables. The PA821A contains a universal power supply to
operate anywhere in the world.

NOTE: When the PA821A 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).
