Lectrosonics Long Ranger IV - Manual (Page 6)

Long Ranger 4
System Setup
This section includes some basic rules that will ensure 5)
trouble-free operation of your Long Ranger system:
1) Make sure the transmitter battery is good or new.
6)
2) Charge up the battery pack in the Long Ranger fully
before you use the system. Charge until the green 7)
charging lamp underneath the CHARGER jack on
the Long Ranger control panel goes out.
3) Set up the system so that the Long Ranger is as far
from large metal surfaces as possible. Metal sur­
faces under the unit (such as pickup truck cabs or
a car top) are generally no problem but large metal
surfaces alongside the Long Ranger may interfere 8)
with wireless reception.
4) If you have more than one transmitter on the same
frequency, turn on only one transmitter at a time.
You cannot use two transmitters at the same time
with a single Long Ranger. You will need to “al­
ternate” back and forth between the transmitters.
Failure to do so will result in an obnoxious whining
sound from the system, and the audio will probably
not be understandable. “Add-on” wireless mic sys­
tems are available separately to permit operation
of two transmitters simultaneously through a single
Long Ranger.
Initial Equipment Adjustments
This section covers the initial adjustments to the 7)
transmitter and Long Ranger that must be made before
the system is placed into operation. The step-by-step
procedures are listed in the order in which they should
be performed:
1) Turn Long Ranger power on - The POWER lamp
lights.
2) Rotate both volume controls counter-clockwise to
their minimum settings.
3) Position yourself behind the Long Ranger so that
the sound from the speaker will be directed away
from the microphone.
4) Plug your microphone into the transmitter. Make
sure the connector is screwed in snugly. 8)
5) Turn the transmitter power on and verify that the red
lamp on it lights. If the lamp is very dim or does not
light, replace the battery.
6) Observe that the green RF lamp on the Long Rang­
er control panel is lighted. This verifies that the unit
a)
is receiving a usable signal from the transmitter.
Use the minimum volume that will enable everyone
to hear. It doesn’t have to be loud to be heard.
Always turn the power off before connecting or
disconnecting external speakers.
The Long Ranger should be elevated for best
coverage. The unit should ideally be at least 2
feet higher than the audience. For example, with
an audience standing on flat ground, the number
of people that can hear clearly will double if you
raise the unit from 5 feet above the ground to 7 feet
above the ground.
During actual operation the Long Ranger should
be located at least 20 feet away from the person
using the microphone and aimed so that the sound
from the speaker is directed toward the audience
and away from the microphone. This will reduce
feedback problems. Feedback is a squealing sound
coming from the speaker when the volume is too
high or the microphone is too close to the Long
Ranger. Feedback is generally much more of a
problem when using lavalier (lapel) type micro­
phones. The headset models are recommended
for use with the Long Ranger system since they
place the microphone pickup much closer to
your mouth, which increases the volume of the
Long Ranger before feedback occurs.
Position the microphone on yourself (or other user)
in the location it will be during actual operation.
If you are using the single-band or dual-band
headset microphone, turn the white knob on the
headset fully clockwise (maximum). The HM162
over-ear microphone should be positioned so that
the pickup element is just to the left of the mouth,
so that breath pops do not strike the capsule. Lava­
lier microphones should be positioned high on the
chest or collar, as close to the mouth as possible
to minimize the possibility of feedback. A handheld
microphone with the H175DC plug-on transmitter
should be kept at a consistent distance from the
mouth during setup and use.
A small screwdriver is supplied with belt-back trans­
mitters to adjust the audio gain of the transmitter to
match your microphone and your voice. The plug-
on transmitter has a small knob for adjusting gain.
The adjustment is made while observing the MOD
LEVEL lamps on the Long Ranger control panel:
Speak at the voice level you will be using during
actual operation.
