Portable Wireless Sound System
Rio Rancho, NM 3
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
batteries. 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.)
Rechargable Batteries and External Power Sources
The standard Long Ranger Portable Wireless Sound
System consists of a combination wireless receiver/
amplifier/speaker with a rechargeable battery pack, a
belt-pack or plug-on transmitter and a microphone.
Optional microphones, extension speakers and add-on
equipment 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
selectivity 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.
General Technical Description
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
continuous. 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 to-
gether to provide even greater area coverage.
The DCR15/2A charger is capable of charging the
batteries 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

Controls and Functions
Control Panel
Wireless Microphone Volume
Turns unit power on and off and also functions as the
volume control for the internal wireless receiver.
POWER A red LED that lights when unit power is on.
RF
A green LED that lights when the companion transmit-
ter is turned on and there is sufficient signal for good
system operation. Internal circuits monitor both signal
level and interference levels and decide if the transmit-
ted signal is strong and “clean” enough for satisfactory
operation. If not, the green RF LED will go out and the
receiver will mute the audio (“squelch”), turning off the
sound output. This action is automatic and requires no
user adjustment.
Mod Level
The red and green MOD LEVEL LEDs continuously
indicate the modulation level (audio level) of the re-
ceived signal from the transmitter and are used when
making initial adjustments to the transmitter.
MIC
This connector is a standard 1/4" phone jack and is
used for plugging in the cord from a low impedance
dynamic microphone.
Line
This mini jack is used for connecting high level, high
impedance outputs from tape decks or other amplifiers.
It also may be used for connecting the “earphone”
output from portable cassette players.
Auxiliary Input Volume
Adjusts the volume of the MIC and LINE inputs.
Aux In/Out
An RCA phono jack that functions both as a line level
input and line level output. This “omnibus” jack is
primarily used for interconnecting several Long Rangers
together for simultaneous operation. This jack can also
be used with a tape deck to either record from or play
back into the Long Ranger. When used with a tape
deck or other audio source, the sound output level must
be controlled by the volume control on the tape deck
since there is no volume control on the Long Ranger for
the AUX IN/OUT jack. When an external device is
connected to this jack, the loudness of the Long Ranger
will usually be reduced.
DCR15/2AU Charger
A special jack used for connecting the charger when
charging the battery pack. The green LED located
under the jack lights when the batteries are charging.
This LED automatically goes out when the batteries are
almost fully charged.
12V DC Output
A special jack used to supply power to the Add-On
receiver when that option is installed.

12V DC Ext Power
A special jack used to connect an external 12 Volt DC
source to the unit to substitute for the “on-board” battery
pack. It is most commonly used for connecting the
Long Ranger to a vehicle cigarette lighter or 12V DC
auxiliary receptacle. When an external power source is
connected to this jack, the on-board battery pack is
automatically disconnected.
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
External 8 Ohm Speakers
Two jacks which are used to connect external 8 ohm
loudspeakers such as the Lectrosonics H300 re-entrant
horn. This jack can also be used to power other brands
of loudspeakers, but be sure that the speaker has a
rated impedance of 8 ohms. The left-hand jack discon-
nects the built-in horn when the plug is inserted. The
right-hand jack will operate the internal horn along with
the external speaker. The efficiency of different makes
and models of speakers varies significantly. Even
though two different speakers are both rated at 8 ohms,
their loudness could be quite a bit different. The other
specification to compare when considering the use of
another speaker is the efficiency rating. The horn built
into the Long Ranger is rated at 107 dB SPL (sound
pressure level) at one meter with a one watt input.
Check this specification on the speaker you are consid-
ering. A speaker with a lower “dB’ number will not be as
loud as the horn built into the Long Ranger.

This section covers the initial adjustments to the
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.
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
Ranger control panel is lighted. This verifies that
the unit is receiving a usable signal from the
transmitter.
Initial Equipment Adjustments
This section includes some basic rules that will ensure
trouble-free operation of your Long Ranger system:
1) Make sure the transmitter battery is good or new.
2) Charge up the battery pack in the Long Ranger fully
before you use the system. Charge until the green
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
surfaces 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 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 “alter-
nate” 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
systems are available separately to permit opera-
tion of two transmitters simultaneously through a
single Long Ranger.
System Setup
5) Use the minimum volume that will enable everyone
to hear. It doesn’t have to be loud to be heard.
6) Always turn the power off before connecting or
disconnecting external speakers.
7) 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.
8) 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 feed-
back 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.
7) 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.
Lavalier microphones should be positioned high on
the chest or collar, as close to the mouth as pos-
sible 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.
8) A small screwdriver is supplied with belt-back
transmitters to adjust the audio gain of the transmit-
ter 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:

Rio Rancho, NM 7
a) Speak at the voice level you will be using during
actual operation.
b) While speaking, adjust the transmitter gain until the
green MOD LEVEL lamp on the Long Ranger
control panel is lighted or flickers and the red MOD
LEVEL lamp blinks on the loudest words. Raise
and lower your voice while observing the lamps.
The red lamp should blink occasionally.
9) Now adjust the WIRELESS MICROPHONE VOL-
UME control on the control panel to a level where
everyone can hear. You will probably have to do
this in several steps. If you attempt to adjust the
volume yourself while standing and just behind the
Figure 3 - Transmitter Gain Adjustment
Green
LED

LED
unit, you will likely have a “feedback” problem. It is
convenient to have another person adjust the
volume while you transmit from a position 20 feet or
more behind the unit.
REMEMBER--the transmitter gain control is used only
to adjust for proper MOD LEVEL lamp indications. DO
NOT use it to adjust the output volume of the Long
Ranger speaker. Different voices and different micro-
phones will usually require readjustment of the transmit-
ter gain control, so check the adjustment frequently. If
several different people will be using the system and
there is not time to make the adjustment for each
individual, adjust it for the loudest voice.
While speaking, adjust the transmitter as you observe
the LEDs on the receiver.

MIC JACK
The MIC JACK is a locking micro jack that supplies
“phantom power” for electret microphones such as the
Lectrosonics M119, M140 Lavalier and the HM142V,
HM152V and HM162 headset models. Insert the
microphone cord plug into the jack and rotate it clock-
wise to lock it . It is important that the plug be securely
locked, since the microphone cord serves as the
antenna for the transmitter.
POWER ON/OFF
The POWER ON/OFF switch turns the power on and
off. The switch should be left in the OFF position when
the transmitter is not in use. When the switch is in the
ON position, the battery will be drained even though the
transmitter is not being used.
BATTERY INDICATOR LAMP
The BATTERY INDICATOR LAMP will light when the
transmitter is turned on and will stay lit as long as the
battery is good. As the battery voltage drops, the lamp
will grow dim and finally go out.
MIC LEVEL ADJUST
The MIC LEVEL adjust is a recessed screwdriver
adjustment used to match the gain of the transmitter to
different microphones, individual voices or other audio
inputs such as tape deck outputs.
M175 Battery Replacement
The battery you use in the M175 Series transmitter
should be a 9 Volt lithium or alkaline, available almost
everywhere. A lithium 9 Volt battery will provide the
best performance with over 30 hours of operation. An
alkaline battery will provide up to 15 hours of operation,
and carbon zinc batteries, even if marked “heavy duty”
will only provide about 4 hours of operation. Recharge-
able batteries made to look like 9 Volt batteries typically
only produce 7.2 Volts at full charge, which will only
operate the transmitter for an hour or less. Make sure
your batteries are marked “alkaline.” Short battery life is
almost always caused by weak batteries or batteries of
the wrong type.
The BATTERY LAMP will light when the transmitter is
turned on and will stay lit as long as the battery is good.
As the battery voltage drops, the lamp will grow dim
and finally go out. Even after the lamp goes out, there
may still be up to an hour or more of operating time
remaining. When the battery voltage is too low for
proper transmitter operation, the sound from the
wireless system may be distorted, intermittent or totally
absent. When the transmitter is first turned on, the
lamp may light for a short while even with a bad battery.
It is good practice to check the brightness of the lamp
after the transmitter has been on for several minutes
and to note the brightness occasionally during use.
AUDIO SWITCH
The AUDIO SWITCH (M175-LS only) is a toggle type
on-off switch used to shut off the audio signal without
shutting off the RF carrier of the transmitter.
(Note: The M175DC, Digital Code Squelch version
is operationally identical to the standard M175.)
M175 Controls and Functions
To replace the battery, open the bottom battery door
cover with your thumb, rotate the door until it is perpen-
dicular with the case and allow the battery to fall out of
the compartment into your hand. It is difficult to install
the battery backwards. Observe the large and small
holes in the battery contact pad before inserting a new
battery. Insert the contact end of the battery first,
making sure the contacts are aligned with the holes in
the contact pad, and then swing the door closed. You
will feel it snap into place when it is fully closed.

H175DC Controls and Functions
The H175DC may be used with a wide variety of
microphones. The 3-pin XLR type connector on the
H175DC allows the transmitter to be used with any
dynamic microphone, as well as many two wire positive
bias lavalier systems (such as those systems supplied
by Lectrosonics.)
INPUT JACK
Standard 3-pin XLR type. Pin 2 is signal, pin 3 is signal
ground, and pin 1 is case ground. The H175DC locks
onto a standard microphone. The XLR connector is
permanently bonded to the locking assembly, and is not
normally replaceable. The electret bias is 5 Volts at
1mA or less. The bias is connected in a “phantom”
manner and will not interfere with any standard bal-
anced microphone. If severe noise is experienced
when the microphone is wiggled, the cause is an
unbalanced condition between pins 2 and 3 of the
microphone.

BATTERY POWER LED
Glows brightly when battery is good. A weak or dim
power LED means that the battery is weak, and has
about an hour of operation left. If the LED fails to light,
the battery should be replaced. The POWER LED is
connected to a precision battery test circuit that con-
tinuously monitors battery voltage. The LED is at full
brightness with a new 9 Volt alkaline. As the battery
voltage drops during use, the LED brightness will also
decrease. After 12 to 15 hours the battery voltage will
be about 7 Volts. The LED will be completely extin-
guished. Since the internal circuits are all tightly
regulated and the RF output stage has a separate
discrete regulator, the transmitter will continue to
operate to a battery voltage of 6.5 Volts. From 6.5 Volts
to 6 Volts, the transmitter will still operate, but with
degraded performance. Please note that a weak
battery will sometimes light the POWER LED immedi-
ately after turn on, but soon will discharge to the point
where the LED will extinguish.
The combination of an accurate battery condition
indicator and regulation of all internal circuits guaran-
tees much longer battery life, as well as consistent
performance over the life of the battery.
LEVEL CONTROL
Used to adjust the audio input volume for the proper
modulation level. Rotate knob until the LEVEL LED on
the receiver flickers when there is an input signal. The
LIMIT LED on the receiver should light occasionally.
(Note: The H175DC, Digital Code Squelch version
is operationally identical to the standard H175.)

1) Install the Microphone onto the transmitter.
a. Unscrew the collar by turning it fully clockwise until
it stops.
b. Turn the collar two turns counter-clockwise to
extend the locking tab
c. Press the mic onto the XLR connector until you
hear a “click.” The click indicates the mic has
locked into place.
d. Pull on mic to ensure that it is secure.
e. Tighten the collar by turning it counter-clockwise.
Warning: Worn mics may not “click” and may
not properly lock.

2) Turn on the receiver and adjust the Long Ranger
volume to minimum.
3) Turn on the transmitter. The RF LED on the re-
ceiver should come on.
4) Hold the microphone as you will when you will be
using it.
5) While speaking, adjust the transmitter gain until the
green MOD LEVEL lamp on the Long Ranger
control panel is lighted or flickers and the red MOD
LEVEL lamp blinks on the loudest words. Raise
and lower your voice while observing the lamps.
The red lamp should blink occasionally.
Occasional lighting of the LIMIT LED (about 10-15% of the
time) indicates proper operation
and optimum signal-to-noise ratio.
Even when the transmitter is limiting, little distortion is
produced because of the high linearity of the gain
control circuit in the H175.
6) Adjust the Long Ranger volume level as necessary.
NOTES: The LEVEL control on the transmitter
should not be used to control the volume of your
sound system. This should be done using the
level control on the Long Ranger.
If the mic level is too high - the Red LED on the
Long Ranger will light frequently or stay on. This
condition may cause distortion.
If the mic level is too low — neither LED will light,
or the Red LED will light dimly. This condition will
cause hiss and noise. You may experience severe
reduction in apparent range if the transmitter gain
is too low. It may sound as if you are getting
dropouts. What is actually happening is that you
are hitting your noise floor because the S/N ratio
has been reduced by the low modulation.
The input limiter operates over a full 30dB range
regardless of the gain control setting. The Red
LED should flicker occasionally during operation.

CAUTION! ALWAYS TURN THE LONG RANGER
POWER OFF BEFORE PLUGGING IN OR
UNPLUGGING EXTERNAL SPEAKERS
In some cases, the proper coverage of an audience
requires a second speaker. The optional H300 is
identical to the Long Ranger speaker and can be used
to spread the sound over a broader area.
The output jacks for external speakers are located on
the Long Ranger front panel. The left and right jacks
operate differently. The right jack does not disconnect
the built-in speaker when a plug is inserted into it. This
means that the built-in speaker and the external
speaker will both operate together. The left output jack
disconnects the built-in speaker and powers only the
external speaker. Internal circuits and switching net-
works keep track of the number of speakers hooked up
and select the amplifier impedance so that the full
power of the amplifier is always available. It is impor-
tant that you use only an 8 Ohm speaker in these jacks.
If you are not using Lectrosonics extension speakers,
check the speaker for the proper rating before connect-
ing to the Long Ranger.

To open the battery compartment,
press outward on the cover door in
the direction of the arrow as shown
in the drawing. Only slight, sliding
pressure is needed to open and
close the battery door.
H175DC Battery Replacement
Swing the door open and take note of the polarity
marked inside showing the location of the positive (+)
and negative (-) terminals. Insert the battery and close
the cover by pressing in and across, reversing the
opening procedure. Note that the battery door will NOT
close if the battery is inserted incorrectly, since the
terminals will hit a protective polarity barrier.
speakers are both rated at 8 ohms, their loudness could
be quite a bit different. The other specification to
compare when considering the use of another speaker
is the efficiency rating. The horn built into the Long
Ranger is rated at 107 dB SPL (sound pressure level)
at one meter with a one watt input. Check this specifi-
cation on the speaker you are considering. A speaker
with a lower “dB’ number will not be as loud as the horn
built into the Long Ranger.
The H300 speaker is typically used in conjunction with
the built-in speaker to increase the sound coverage
area. This is done by plugging the H300 into the right
speaker jack, so that both speakers will work together.
In a large area, such as a football field, try to arrange
the speakers so that the listeners are not in the direct
sound field of both speakers. If a listener can hear two
speakers located at different distances, a distracting
“echo effect” occurs. Put the speakers close to one
another in a central location and aim them in opposite
directions to broaden the coverage pattern.
When using two external speakers simultaneously, the
built-in speaker will be automatically disconnected to
prevent overload of the amplifier since a plug has been
inserted into the left-hand jack.

Figure 4 - Add-on Receiver Antenna Connections
Adding a Second Wireless Channel to your Long Ranger
A very popular feature of the Long Ranger is the ability
to add a second wireless channel to an existing system
in the field. The Lectrosonics Add-On Receiver system
was expressly designed for that purpose. The standard
system consists of an Add-On receiver, a transmitter
and a microphone.
The Add-On receiver is supplied with velcro attaching
strips and is equipped with the necessary cabling for
making the connections to the Long Ranger. The
receiver is installed on the Long Ranger by performing
the following steps as shown in Figure 4:
1) The antenna cable for the Add-On is packed
together with screws, lock washers and the velcro
strips. The antenna cable is terminated with two
ring lugs. Feed the lug end of this cable through
the hole in the Long Ranger rear panel upright.
Dress the cable along the top of the battery pack
along with the speaker wires as shown in Figure 4.
2) Remove and discard the two black Phillips head
screws from the bottom of the antenna strip on the
right-hand side of the speaker and from the speaker
mounting block. Using the supplied bright screws
and lockwashers, connect the shield ring lug (the
black wire) to the speaker mounting block. Connect
the centerconductor ring lug (the clear/white wire)
to the antenna. Tighten both screws securely.
3) The Add-On receiver is to be mounted on the Long
Ranger upright with velcro. The receiver should be
positioned, control panel up, between the horn
mounting screw and the screw which secures the
battery pack to the upright. Remove the paper
backing from one side of the velcro and affix it to
the back of the receiver. Remove the remaining
paper backing and affix the receiver to the upright.
4) Route the antenna cable through the hole in the
rear upright panel, above the battery pack so that
the black and white wires reach the speaker
mounting block. Connect the remaining two cables
to the 12V DC OUTPUT jack and the LINE input
jack on the control panel.

Long Ranger 4
LECTROSONICS, INC.14
If you are only using one of the two wireless systems, it
is best to use the wireless system built into the Long
Ranger and leave the Add-On receiver turned off. This
will prevent unwanted noise, hiss or static that could
occur in the unused receiver from entering the Long
Ranger.
Special Note to Dual Channel Users
1) Set up the Long Ranger system according to the
Initial Equipment Adjustments on page 6.
2) Leave the Long Ranger power turned on. Set both
volume controls on the Long Ranger control panel
tominimum.
3) Turn the Add-On receiver power switch to “ON.”
Check to see that the power lamp comes on.
4) Plug the microphone into the transmitter that is on
the same frequency as the Add-On receiver. The
plug on the microphone is a twist-lock connector.
Make sure there is a good connection. If you are
using the head set microphone, turn the white level
control knob on the headset fully clockwise (maxi-
mum).
5) Install the 9 Volt battery into the transmitter, turn the
transmitter on and make sure the red LED on the
transmitter glows brightly.
6) Check to see that the green “RF” LED on the Add-
On receiver glows steadily. This verifies that the
receiver is picking up a good radio signal from the
transmitter.
Initial Adjustments to the Add-On Receiver System
7) This is the most important step in the set up
procedure. Place the microphone in the exact
position where you will be using it. Speak at the
same voice level that you will use during actual
operation. While you speak, use the supplied
screwdriver to adjust the gain control on the trans-
mitter side panel (see pages 5 & 7) while you
observe the MODULATION LEDs on the Add-On
receiver front panel. The green LEVEL lamp should
flicker or stay lit as you speak. The red LIMIT lamp
should blink only on louder words.
8) Adjust the AUXILIARY INPUT VOLUME control on
the Long Ranger control panel for the necessary
loudness. If the transmitter gain controls have been
correctly set on both the Longer Ranger 4 and the
Add-On system, both volume control knobs on the
Longer Ranger 4 panel will be in about the same
position for equal loudness on both systems. It is
not unusual, however, that one of the volume
controls may need to be set higher or lower than
the other one in normal use. Adjust the controls
separately for adequate sound levels for each
microphone.
If it is necessary to use the Add-On receiver by itself,
turn the WIRELESS MICROPHONE VOLUME control
knob on the Long Ranger control panel to minimum.
Then set the AUXILIARY INPUT VOLUME for the
necessary loudness of the Add-On system.

Connect two
Long Rangers
together using
the AUX IN/OUT
jacks.
AUX IN/OUT AUX IN/OUT
Figure 5 - Connecting Two Long Ranger Systems
Multiple Long Ranger Systems
A unique use of the AUX IN/OUT jack is for connecting
two Long Ranger systems together for simultaneous
use. When connected in this manner, they will operate
like a single system. It is best to use two different Long
Ranger units that operate on different frequencies. Any
input on either Long Ranger will appear at both speak-
ers. If the Long Ranger systems are on the same
frequency, only one transmitter can be used at any
given moment.
Second channel (add-on) wireless systems on either (or
both) Long Ranger systems will work fine, as long as
they are all on different frequencies. Each wireless
microphone will have its own volume control. The built-
in wireless in each Long Ranger will be controlled by
the left-hand knob on the matching unit. The volume of
each add-on wireless system will be controlled by the
right-hand knob on the matching unit. All sound from all
wireless microphones will appear on all loudspeakers,
both built-in or external.
Connect the Long Ranger systems together with a
standard RCA (phono) patch cord, male plug to male
plug. It is best to use cords 10 to 12 ft. in length (or
less) to minimize noise that can occur with long cables.
If any of the Long Rangers or add-on wireless system
are on the same frequency, only one transmitter can be
used at a time on that frequency. REMEMBER that if
two transmitters on the same frequency are turned on
at the same time, the receiver will not receive either of
them properly. You will need to “alternate” the use of
the transmitters.
The INITIAL EQUIPMENT ADJUSTMENTS (see page
6) should be performed on each system individually
before the AUX IN/OUT interconnection is made. After
the units are connected together, adjust the volume on
each Long Ranger for the loudness level needed.

Specifications
Operating frequency: 169 to 186 MHz
Audio power output: 33 Watts, RMS, into 8 Ohms
Distortion: less than 1%

Max. audio output (SPL): Over 120 dB at 3 feet
M119 - This is a very small, omni-directional mic used
only as a lavalier (“lapel”) microphone. It may be
prone to feedback since it is usually placed so far
away from the users mouth; however it has a very
flat response and excellent tone quality. The M119
generally works best with the Long Ranger and an
ES300 column speaker indoors at a lower volume
setting. As is true of most omni-directional type
microphones, the M119 is very free from wind noise
and clothing “rattle”.
M140 - A cardioid (directional) microphone for lavalier
(“lapel”) use. Due to the directional pickup pattern,
this model will generally provide more gain (loud-
ness) before feedback than the M119 omni-direc-
tional model. The M140 has a “brighter” sound than
the M119 (the treble is boosted). This crisper
sound normally improves the clarity that is some-
times lost with lavalier type microphones. The
M140 is subject to wind noise and generally works
best indoors, however it is supplied with a foam
windscreen which helps to prevent noise caused by
wind.
HM142V - This single-band headset microphone is
normally worn on the head, but can also be worn
around the neck for hands-free operation. It
provides maximum gain before feedback since the
microphone is very close to the user’s mouth. The
built-in volume control helps control feedback in
difficult environments, such as when the user must
be close to the Long Ranger. Worn on the head,
the microphone will remain at a constant distance
from the user’s mouth, which keeps the volume of
the sound system constant as your head moves.
Microphone Choices
HM152V - A double-band headset microphone intended
to be worn on the head. The pickup element and
tonal characteristics are the same as the single-
band HM142V, but it is more securely mounted and
in most cases, more comfortable, due to the fully
adjustable dual headband. The same volume
control is provided to help control feedback.
HM162 - A “over the ears” noise cancelling microphone
that uses a dual-element design to minimize
feedback when the microphone is close to the
speaker.
Other brands of microphones may be used, provided
they are the correct type, with an appropriate connector.
Consult the factory or your dealer if you are not sure. A
mis-matched microphone will generally cause back-
ground noise (hiss) or feedback problems, or may not
work at all.

Service and Repair
If your system malfunctions, you should attempt to correct or isolate the trouble before concluding that the equipment
needs repair. Make sure you have followed the setup procedure and operating instructions. Check the interconnect-
ing cables and then go through the TROUBLESHOOTING section in this manual.
We strongly recommend that you do not try to repair the equipment yourself and do not have the local repair shop
attempt anything other than the simplest repair. If the repair is more complicated than a broken wire or loose connec-
tion, send the unit to the factory for repair and service. Don’t attempt to adjust any controls inside the units. Once set
at the factory, the various controls and trimmers do not drift with age or vibration and never require readjustment.
There are no adjustments inside that will make a malfunctioning unit start working.
LECTROSONICS’ Service Department is equipped and staffed to quickly repair your equipment. In warranty repairs
are made at no charge in accordance with the terms of the warranty. Out-of-warranty repairs are charged at a modest
flat rate plus parts and shipping. Since it takes almost as much time and effort to determine what is wrong as it does
to make the repair, there is a charge for an exact quotation. We will be happy to quote approximate charges by phone
for out-of-warranty repairs.
Returning Units for Repair
For timely service, please follow the steps below:
A. DO NOT return equipment to the factory for repair without first contacting us by letter or by phone. We need to
know the nature of the problem, the model number and the serial number of the equipment. We also need a
phone number where you can be reached 8 A.M. to 4 P.M. (U.S. Mountain Standard Time).
B. After receiving your request, we will issue you a return authorization number (R.A.). This number will help speed
your repair through our receiving and repair departments. The return authorization number must be clearly shown
on the outside of the shipping container.
C. Pack the equipment carefully and ship to us, shipping costs prepaid. If necessary, we can provide you with the
proper packing materials. UPS is usually the best way to ship the units. Heavy units should be “double-boxed” for
safe transport.
D. We also strongly recommend that you insure the equipment, since we cannot be responsible for loss of or dam-
age to equipment that you ship. Of course, we insure the equipment when we ship it back to you.
