204.600 MHzDiversity Signal Indicators for A and B Antennas.
These lights glow amber
when A, B, or both antennas are receiving usable RF (radio frequency) signals.
RF Level Indicators.
Five lights per antenna glow to indicate RF signal strength.
The more lights that glow, the stronger the received signal. If none of these lights
glows, no signal is being received.
Audio Level Indicators.
Five lights glow to indicate audio signal strength. Green
lights indicate normal operation. An amber light indicates approaching overload
condition. A red light indicates excessive audio levels.
Sets the point at which the receiver "mutes" when the transmitter
signal becomes noisy, weak or fails. This control is factory-set at the 12 o'clock
position to provide optimal operation in most applications.
Audio Output Level Control.
Lets you adjust output level to match the input level
requirements of a mixer or amplifier. In most situations, this control should be set
Power On Indicator.
This green light glows to indicate that the Power switch is on
and power is applied to the receiver.
Power On/Off Button.
Turns the receiver on and off.
UHF-type connectors provide connection to the supplied
1/4-wave antennas or to coax cable used with remote antennas. They also provide
connection to the optional Shure WA421 remote antenna cable kit used with
optional WA380 telescoping and WA490 cable-type 1/2-wave antennas.
XLR connector provides balanced low-impedance mic level
or line-level output. Quarter-inch phone jack provides unbalanced auxiliary level
Mic/Line Slide Switch:
Controls output of balanced XLR connector. It can be set
for microphone (-20 dBV maximum) or line-level (+0 dBV maximum).
Power Jack:Accepts power from the supplied ac adapter, or from any filtered 15
to 18 Vdc (400 mA minimum) supply. It will also accept the dc power cord from a
Shure WA405 Antenna Power/Distribution System.
