Shure L 11 Manual

GENERAL
Shure L Series wireless microphone systems are single-channel
systems operating in the VHF band between 169.445 MHz and
216.100 MHz. Each system consists of a hand-held L2 Microphone-
Transmitter or an L11 Body-Pack Transmitter with a lavalier micro-
phone or instrument adapter cable, and an L3 or L4 Receiver. Each
component is briefly described below.
L2 Hand-Held Microphone-Transmitter. The L2 is a hand-held
microphone with a built-in transmitter. It features superb frequency
response, extended dynamic range, a batterytest light, and heavy-
duty grille with built-in pop filter. The L2 is supplied in four models:
L2/58, which includes the world-famous Shure SM58 cardioid
l
dynamic microphone
L2/BETA58®, which includes the Shure BETA58 supercar-
l
dioid dynamic microphone
L2/87, which includes the Shure SM87 supercardioid condens-
l
er microphone
L2/BETA87, which includes the Shure BETA87 supercardioid
l
condenser microphone
L11 Body-Pack Transmitter. The L11 features extended dy-
namic range, a battery test light, noiseless muting, and a rugged
case.
Lavalier Microphone. A lavalier electret condenser microphone
plugs into the L11 Body-Pack Transmitter. Five microphone models
are available with the L Series body-pack systems: the WL83A,
WL84A, and WL93 lavalier type microphones, the WM98 instru-
ment microphone, and the WCM16 headworn microphone. Each
microphone features optimized frequency response, low distortion
and low RF susceptibility.
WA302 Instrument Adapter Cable. The WA302 instrument
adapter cable is used with electric guitars and other electric instru-
ments instead of a lavalier microphone. The WA302 plugs into the
microphone input on the L11 Body-Pack Transmitter.

L3 Receiver. The L3 offers interference-free operation, superior
quieting, and highly effective noise reduction. It has a removable
¼-wave antenna and is rack-mountable with an optional mounting
kit.
L4 Diversity Receiver. The L4 includes all of the features of the
L3 receiver plus Shure's exclusive MARCAD® circuitry. MARCAD
(MAximum Ratio Combining Audio Diversity) goes beyond stan-
dard switching RF diversity. It constantly monitors the two signals
and combines them when both signals are usable. The result is in-
creased RF gain, improved reception, and exceptional freedom
from dropouts.
PERFORMANCE CHARACTERISTICS
Operating Frequencies. A total of 28 frequencies, computer-se-
lected for interference-free operation, are readily available. Other fre-
quencies can be ordered on a special basis.
Multiple Miking. Up to ten L Series systems can be operated in a
single sound installation, simultaneously and without intermodula-
tion problems. However, each system must operate at a different
frequency.
Transmitter Range. The maximum operating range for any L Series
system is normally 100 meters (330 feet), although operation at 300
meters (1000 feet) is often possible. Conditions at the installation site
(reflective surfaces, obstacles, radio interference, etc.) will ultimately
dictate a system's limits. For best results, keep the distance between
the transmitter and the receiver as short as possible.
Power Requirements. The L3 and L4 receivers are supplied
with separate PS20 adapter for 120 VAC, 60 Hz power or a PS20E
adapter for 220/240 VAC, 50 Hz power. The receivers can also be
powered by any filtered 12.5 - 18 VDC power source. The L2 and
L11 transmitters operate on a 9-volt alkaline or 8.4-volt nicad bat-
tery. Battery life depends on the type and brand of battery.
