Portable Wireless Sound System
General Technical Description
The standard Long Ranger Portable Wireless Sound
System consists of a combination wireless receiver/am­
plifier/speaker with a rechargeable battery pack, a belt-
pack or plug-on transmitter and a microphone. Optional
microphones, extension speakers and add-on equip­
ment for a second wireless channel are available.
The Long Ranger features a VHF wireless microphone
system with a transmitter-to-receiver operating range of
up to 750 feet. The receiver is designed for high selec­
tivity to prevent interference from other transmitted radio
signals. The system is designed and constructed for
rigorous portable use with the antenna integrated into
the horn speaker to eliminate damage.
The Long Ranger will operate from 8 to 12 hours
from the “on-board” rechargeable battery pack before
recharging is necessary. The actual operating time is
dependent upon the type of usage... intermittent or con­
tinuous. The unit can also be operated from an external
12 Volt DC source or an AC wall outlet.
The amplifier produces 33 Watts, RMS, into the 8 Ohm
horn speaker. The sound output will cover an area the
size of a football field under average outdoor conditions.
Several Long Rangers can be easily connected togeth­
er to provide even greater area coverage.
Rechargeable Batteries and External Power Sources
The built-in battery pack in the Long Ranger is charged
by plugging the DCR15/2AU charger into the jack
labeled DCR15/2AU CHARGER on the control panel.
Connect the charger into a standard 110 or 220 Volt AC
outlet. (The DCR15/2AU charger can be operated from
110/220V, 50/60Hz.) The green lamp beneath the jack
will light as long as the batteries are charging. When
the batteries are almost completely charged the green
charging light will go out. You may leave the charger
plugged in after the green light has gone out with no
danger of damage to the system. In fact, we recom­
mend charging the system whenever it is not in use,
then the system will always be “ready to go.”
The DCR15/2AU charger can charge the batteries in as
little as 2 1/2 hours. If the unit is completely run down, it
may require as much as 6 hours to fully charge the bat­
teries. Leave the charger plugged in at least until the
green lamp below the CHARGER jack goes out.
(NOTE: In the case of severely discharged batteries
(this can happen if the Long Ranger has been left on
constantly for several months), it may be necessary to
charge the unit for a much longer time. Up to 10 days
charge time is not uncommon in these circumstances.)
The DCR15/2A charger is capable of charging the bat­
teries and running the Long Ranger in normal operation
at the same time. The time required to fully recharge
that batteries will be longer if the unit is being used
while charging the battery pack.
CAUTION : USE ONLY THE SUPPLIED
DCR15/2A CHARGER. DO NOT USE THE
OLDER CH40 CHARGER IN THE NEW LONG
RANGER 4. THE CH40 WILL NOT CHARGE THE
BATTERIES IN THE LONG RANGER 4 AND WILL
BE DAMAGED IF USED.
The Long Ranger can be operated from an external 12
Volt DC source such as an automobile battery or, most
commonly, from the cigarette lighter receptacle in your
vehicle. To use an external power source it must be
connected into the 12V DC POWER INPUT jack on the
Long Ranger front panel.
CAUTION: Make sure you comply with the polarity
markings on the jack. The correct plug for making
the co nnection is a Radio Shack 274-1567 size K
coaxial DC power plug. Radio Shack also stocks
cigarette lighter plugs (with built-in fuse) and cords
to construct a suitable assembly
