SETUP AND INSTALLATION
Selectingthe AppropriateAntenna(s):
Three versions of the WA380 Half-Wave Antenna are
availablefor wireless frequency bands:
WA380A - 169to 185MHz
WA380B - 185to 200 MHz
WA380C - 200to 230 MHz
When multiple WA404's are used, select antennas for
eachWS404independently.When morethanonefrequen-
cy band is covered, select antennas asfollows:
If the frequencies span two adjacent bands, select
antennasfor the lowest frequency band.
If the frequencies span all three bands, use one
WA380A Antenna and one WA380C antenna.

The WA404 amplifies the wireless transmitter signals to
compensatefor insertionlossandfeeds the signalsto their
respectivewireless microphonereceivers.
Inaddition,four 15Vdc outputsontherearoftheWA404
providea combined current of 2 amps to power up to four
Shure diversity wireless microphone receivers, eliminating
the needfor external power supplies. The built-in, high-effi-
ciency switching power supply will accept mains voltages
from 100 V to 240 V (with the appropriate ac power cord).
TheWA404,for usewith 100to 120V, isfurnishedwithade-
tachable, 3-conductor power cord with a 3-pin grounded
U.S. type ac connector. The WA404E, for usewith 2201240
V, issuppliedwithapowercordthathasaSchukoconnector
at the mains end.
When planninga multiplemicrophoneinstallation,keep
in mind that each microphone must transmit on a different
frequency and that frequencies must be selected in accor-
dancewithsystemcharacteristics.ContactyourShuredeal-
er for further informationand assistance.
The WA404 is designed for use with Shure Model
WA380 Half-WaveAntennas and ModelWA420 Extension
Coaxial Cables or other high-quality 50 coaxial cables.

nassuppliedwith thewireless systems.
Mountingthe WA404 on a Flat Surface
To use the WA404 on a flat surface (table, shelf, work
bench,etc.), attachthe four suppliedadhesive-backed rub-
ber bumbersto the bottomcornersof the unit.
ConnectingAntennas to the WA404
1. ConnecteachantennatotheWA404 using6.1 m(20ft)
WA420 ExtensionCables.
2. IfWA380antennasareused,locateand mounttheanten-
nas remotely as described inthe instructionsheet. Use ei-
ther the mountingbracketssuppliedwith theWA420 exten-
sion cables for wall mounting, or a Shure Model WA440
Rack Mount Ki for rack mountingthe antennas, or Shure
ModelA57 Swivel Adapters (or equivalent) if standard mi-
crophone stands are
used to support the antennas.
3. Fullyextend all telescoping sections of the WA380 an-
tennas for optimum reception. Make sure that the ex-
tended antennasarevertical.
ConnectingReceiversto the WA404*
1. Connectthe Antenna Inputsof the receiversto the RF
Outputs of theWA404 with the supplied
rf cables.
2. Connectthe receiverstothe 15Vdc outputsonthe rear
panel of the WA404 using the Power Interconnect
cablesfurnished. Notethat the interconnectcables are
furnishedwith locking plugsthat matewith the WA404.
*Check power requirementsbeforeusingwith receiversmade by other
manufacturers.

Connecting Powerto the WA404
1. Connect the WA404 to the power mains, using the cor-
rect power cable. For a 100 to 120 V power source
(WA404),usethe standardthree-pronggrounded cable
supplied.Fora 2201240 V powersource (WA404E),use
the cord with the CEE 717 ("Schuko") connector at the
mainsend.
NOTE: For systems requiring other mains connectors,
procureapowercordhavinganIEC320typematingcon-
nectorto connect totheWA404and an appropriateplug
