or high end of the spectrum, i.e. channels 1,
2,3,4,5 or channels 65, 66, 67, 68. If there is
another 2.4 GHz source in the room, grouping
the channels reduces the chances of an overlap. Do not start by spreading your channels
throughout the 70 channel range of the system – you are more likely to encounter interference this way.
Be sure that all transmitters are off.

place. In the default factory setting, dynamic FBX filters will still
be held in reserve to catch and eliminate new feedback, regardless of how or when SETUP mode is exited. (See Section
14.3.2 for details on the differences between fixed and dynamic FBX filters and Section 13.4.2.1 for instructions on
changing the balance of fixed versus dynamic FBX filters using the Remote Control Software or Appendix D for
using the Dip Switches on the back of the receiver).
3.2.2. FBX Bypass
The BYPASS button (Fig. 3d) bypasses only the FBX filters, and
not the additional signal processing (de-essing, compression and
Mic SuperModelingTM) available on the True MobilityTM Wireless
Receiver. This is a useful button that allows comparison of the
sound quality when FBX filters are in place, to the sound with no
filters (the quality should be very similar). Before pressing BY-

COMPRESSOR/LIMITER
Vocal Settings
RAT IO A soft voice could be set to 2:1, whereas a loud voice might
require a ratio setting of 6:1.
THRESH The higher the threshold setting, the more signal is required to
initiate compression. Ideally this should be set to reign in peak
levels, and allow signals of lower gain to pass uncompressed.
Threshold settings will depend on the nature and variety of the
signal source.
ATTACK Short attack times usually work well for voice. However, too
strong a compression ratio, too low a threshold, and too fast an
attack may attenuate speech consonants, which provide important intelligibility cues to the audience, thus compromising
clarity.
Guitar Settings
RAT IO A high compression ratio (with gain makeup) will add sustain
to held notes and chords.
THRESH Moving the threshold will change the audible thick/thinness of
the guitar tone, but generally you want to compress all the notes
played.
ATTACK Be wary of too quick an attack, which may reduce the percus-
sive attack of the guitar notes.
In general, be wary of too much gain makeup, and too high a compression ratio, which may make a noisy guitar amplifier more objectionable.
Ratio settings might range from 6 to 19:1, threshold variable, slower
attack, soft knee, output gain boosted slightly to significantly depending
on amount of compression.

Antenna Placement Caution
As a general precaution, keep 2.4 GHz
cordless telephones, microwave ovens,
WLAN antennas and 2.4 GHz wireless
video camera transmitters twice the distance from your Sabine wireless microphone system antennas as that of your
Sabine 2.4 GHz transmitters.
Quick Setups
3.3. Tips for Good RF Performance
• It is best to keep the system’s channels c lose together at the low or high
end of the spectrum, i.e. channels 1, 2, 3, 4, 5 or channels 65, 66, 67, 68. If
there is another 2.4 GHz source in the room, grouping the channels reduces
the chances of an overlap. Do not start by spreading your channels throughout the 70 channel range of the system -- you are more likely to encounter
interference this way.
• Avoid potential sources of RF interference by performing a scan using
Sabine’s Remote Control Software., which will reveal the ambient RF level
in your area on each channel of your system. Please refer to Section 13.4.2.5.
for information on the RF Scan function, which will automatically determine
the best RF channels to use.
• If you cannot perform a scan then proceed to use your system, beginning
with Channel 1. If you hear any RF “hits” or dropouts, then move to another
of the 70 available channels. If you have multiple mics keep all your channels grouped together.
• For best results, maintain line-of-sight from transmitter to receiver. Use
either front or rear panel antenna mounting to maintain line-of-sight.
• Mount receiver antennas at 90 degrees to one another, leaning away at 45
degree angles, in the same plane.
• When using multiple receivers, try to maintain at least 1 foot (30 cm) distance between antennas from different units. When such antenna spacing
proves difficult or impossible, we recommend using Sabine’s SWA6SS
Antenna Distribution Amplifier. The SWA6SS works with up to six receivers,
or 12 channels.
• Maximize the distance between the receiver and light sources, such as
fluorescent bulbs or neon signs, which may emit very short-range, broadband interference.
• Maximize the distance between transmitters and receivers and potential
sources of RF interference.
• Maintain a minimum distance of at least 3 meters (10 feet) between transmitters and receivers or extension antennas. This can solve many anomalies.
• Turn on your system one component at a time, beginning with the first
receiver.
• Be careful not to set more than one transmitter to the same channel; each
paired transmitter and receiver should be set to unique corresponding
channels, until all channels are receiving clearly and cleanly.
3.4. Common Sources of RF Interference
• Microwave ovens: In the vast majority of situations, interference from
microwave ovens will not affect performance of your SWM7000 series microphone systems. Since barriers such as walls work to block interference, a microwave oven will likely present a problem only when located in
fairly close proximity within the same room as the wireless receiver (or
reception antenna). See caution at left.
• Wireless Local Area Networks (WLANS): These computer network devices allow computers to connect via wireless devices that act as both
receivers and transmitters. These low-powered transceivers often have
selectable channels and can utilize the entire 2.4 GHz band. In general,
Sabine microphones should not be affected by these WLANS because
their spread spectrum technology does not present a problem for the Sabine
Smart SpectrumTM system. The Sabine wireless system will not interfere
with the WLAN. See caution at left.
Sabine 2.4 GHz Smart Spectrum® Wireless

10
• 2.4 GHz Cordless phones: These home telephones broadcast at very low power and
should not present interference problems for your Sabine wireless. This is especially
true if the telephone uses spread spectrum technology. See caution at left.
• Wireless Video Cameras: Certain wireless video cameras (X10, for example) use the
2.4 GHz band. These devices are also very low power and, in general, should not
present a problem when using the SWM7000 system. See Section 5 Receiver
Operation for methods of optimizing clear reception and minimizing interference. See
caution at left.
In the event problems still arise, see Section 5 Receiver Operation for methods of optimizing clear reception and minimizing interference.

4. TRANSMITTER OPERA TION
4.1. First step
Before you begin, let’s look at a few basics regarding your transmitters. The
handheld mic is ready to go — the microphone and transmitter are combined in one unit. To use the belt pack transmitter, however, you will have to
connect a lavalier or headworn microphone (or instrument pickup) to its
input. Sabine lavalier and headworn mics, and Sabine’s guitar/instrument
connector (SW70G-TA4) come equipped with the proper TA4F connector,
and are ready to plug right in. Be sure to line up the pins properly — do not
force the connector into the belt pack.
If you are using a different microphone with the Sabine belt pack, please
refer to the Appendix A for the required wiring plan. Failure to use the
proper wiring scheme may damage your mic or the belt pack, and void your
warranty.
Use the clip on the back of the belt pack transmitter to attach it to your belt or
clothing. The spring clip can be removed and reversed, to allow the transmitter and antenna to point either up or down in its clipped-on position. You
can also remove the clip if you choose to keep the transmitter in your pocket.
NOTE: it is essential that transmitters retain a line-of-sight relationship with
the receiver antennas.
4.2. Displays and Settings
Your Sabine 2.4 GHz Smar t Spectrum handheld microphone and belt pack
transmitter have many powerful features, all of which are easily monitored
(using the transmitter LCD display) and adjusted. The controls and displays for both handheld and belt pack transmitters are almost identical in
function, though positioning differs (compare figures 4b & 4c). The LCD
display and one control switch are located on the exterior of the transmitters.
A more powerful set of recessed controls is located under the hinged access
panel, to prevent accidental or inappropriate alteration of settings.
4.2.1. LCD Display
When the transmitter is first turned on, it shows an initial test screen (Fig.
4f), followed by the default screen (Fig. 4g). The LCD also reverts to this
default display within a few seconds after any programming changes are
made with the recessed controls. The default LCD display always shows
transmission channel, audio level, and battery voltage level; additional
information will appear to indicate important changes caused either by
user adjustments, or automatically as transmitter status changes.

PAD Settings
Your new Sabine wireless handheld microphone is designed to accept a wide range of
input levels, from spoken word all the way
up to screaming vocals. In order to accommodate this broad range of inputs, the transmitter has a PAD setting. Handheld mics are
set to a factory default of -14 dB, which is
the preferred setting for concert vocal performance.
If you need more output out of a microphone
(the receiver LCD audio meter shows the mic
output level) then change the PAD settings
as described below. When any level of attenuation is programmed, the default screen
will illuminate P AD.
Transmitter PAD Adjustment

4.2.3. Adjusting T ransmitter Settings
DEFAULT/CHANNEL: Press the Select button to enter Edit Mode, and repeat
until the CHANNEL indicator flashes. In this mode, the Up/Down buttons will
adjust Transmission Channel (1-70 available).
INPUT: (SW75-T Beltpack T ransmitter only) Either “MIC” or “INSTR” for microphone or instrument. Y ou are required to choose the input in order to progr am
both the transmitter and the receiver to optimize the input settings. Choosing
MIC automatically selects the 75 Hz roll-off filter. You can choose to remove
that but the extended low frequency response of the SW75-T may reproduce
too much low energy for your system, so beware. Choosing INSTR automatically removes the 75 Hz roll off filter for that added bottom end in your instruments. NOTE: You can manually change that filter setting as needed.
Electric Guitar/Bass & FBX: For best results, when using the SW75-T
Beltpack Transmitter for electric guitar or bass, put your receiver’s FBX
Feedback Exterminator into BYPASS mode. FBX BYPASS is acces-
NOTENOTE
sible via the receiver front panel or Remote Software control.
Guitar Cord Simulator
(Beltpack Transmitter Only)
This feature allows you to fine tune the sound of your instrument while it
is patched into your Sabine wireless beltpack. For instructions please
refer to page 22.
PAD: Transmitter PAD setting. Press the Select button until the PAD indicator flashes. The Up/Down buttons will adjust attenuation (SW70-H1: 0, -6,
-14, -20 dB; SW75-T: 0, -3, -6, -10, -14, -17, -20, -23, -26, -30, -34, -37, -40 dB).
When any level of attenuation is programmed, the default screen will illuminate PAD. See margin notes on this page and p.15 for settings instructions.
TIME: Battery Run-Time Hours. Selecting this option changes the display to
indicate the length of power-on time (hours and minutes) since the last
battery change or recharge.
NOTE: Battery run-time hours will reset when the transmitter (with battery in
place) is connected to a charger. In the case of the charger, run-time hours
will not start again until the charger is disconnected. You can manually reset
the run-time hours by pressing both the up and down arrows. Use this to
count hours when you use alkaline batteries.
LOW FREQUENCY ROLL-OFF: Selecting this option adds a 12 dB/octave
low frequency roll-off filter, starting at 75 Hz, to the audio output of the transmitter. A roll-off filter may help reduce microphone handling noise, or other
unwanted low frequency content. Pressing the Up or Down button toggles
between the conditions of no filter (indicated in the display as L 0) or low rolloff (indicated by L 75).
INTERNAL CONTROL OF EXTERNAL SWITCH: The recessed controls include a 3-position switch, which in turn determines how the transmitter’s
external two-position switch behaves (see figures 4a, 4b & 4h). From left-toright, the 3 positions of the internal switch correspond to the following external switch operations:
Sabine 2.4 GHz Smart Spectrum® Wireless

Transmitter Operation
1. ON/OFF. In internal position #1, the external switch acts as a typical on/
off switch. Use this setting if you trust the microphone user to switch the
microphone on and off as needed, and/or wish to conserve transmitter
battery life during down times. In the ON position the transmitter LCD
will display ON. Both audio and RF are on. In the OFF position the LCD
ON is no longer illuminated. Both RF and audio are off, and the battery
run-time hours meter is off. Note that Sabine’s squelch system prevents any “popping” when switching the transmitter on and off. However, this protection causes a very shor t “power-on” delay in the reactivation of the audio when the external switch is turned from OFF to ON.
2. ON/MUTE. In internal position #2, the external switch acts as a typical
mute switch. Use this setting if you trust the microphone user to switch
the microphone audio output on and off as needed; it will not conserve
battery life in MUTE condition, but will allow the receiver to monitor and
display the RF signal strength in either switch position. In the on position the default LCD will display ON. Both audio and RF are on. In the off
position the word MUTE is displayed in the LCD. The audio is muted
but the transmitter is still transmitting the RF signal, and the battery runtime meter is running. There are no audible pops when switching the
transmitter between MUTE and ON. Switching from MUTE to ON will
instantaneously pass audio signal (there will be NO delay as with internal position #1).
3. ON/ON. In internal position #3, the external switch is disabled. The
transmitter (both RF and audio) is always on, and the word ON is always displayed in the transmitter LCD screen. Use this setting if you do
not want to allow the speaker or performer to turn off the transmitter, or
are worried that a transmitter may be accidentally turned off. Caution:
When your program is over we suggest you move this switch to another
setting so you can turn off the transmitter and save your battery. You may
also elect to remove the battery (though replacing the same one will
restart the run-time meter and affect its accuracy accordingly).
Once you have completed the transmitter setup, you are ready to work with your
receiver (see Section 5). First, however, let’s talk about the issues and solutions concerning the source of transmitter power: the battery.
4.2.4. T ransmitter Battery Management
4.2.4.1. Battery problems and Sabine solutions
Rechargeable Battery memory . Batteries that are repeatedly recharged
prior to a complete discharge may fail more quickly in subsequent uses.
This problem is usually referred to as “battery memory.” Fortunately,
Sabine’s innovative Tireless Wireless™ Charger takes steps to avoid
this problem, by automatically reconditioning the battery whenever its
intelligent diagnostics determine this is appropriate. Sabine’s Tireless
Wireless™ Charger will insure maximum life per battery charge, and
also prolong the useful multiple-charge life span of rechargeable batteries.
Battery life. Both handheld and beltpack transmitters can work with
disposable alkaline, disposable heavy-duty (manganese dioxide-carbon zinc), or rechargeable Nickel Metal Hydride (NiMH) batteries. We
specifically caution against using NiCad rechargeables due to wellknown battery memory problems, and specifically recommend using
the Sabine-supplied SWBAA2 (AA for the H1 Series handhelds and
beltpack) batteries. The rechargeable SWBAA2 batteries will last about
8 hours per recharge (typically, alkaline AA batteries will last about 10
hours). NOTE: Heavy-duty batteries will fall somewhere in the middle,
between rechargeables and alkalines.
Beltpack Transmitter
PAD Settings
The SW75-T beltpack transmitter has a broad
range of PAD settings, which allow you to
use it with almost any microphone or instrument. As in all audio equipment, the setting of
the input level is crucial to achieving the best
sound quality. Setting minimal PAD levels (-3,
-6, or -10 dB) may produce a distorted sound
if you are using a high output microphone or
instrument. Conversely, setting a more extreme PAD level (-40, -37, or -34 dB) may
require you to raise your system gain unnecessarily, resulting in a noisier output. Watch
the input meter on either the transmitter or
the receiver (see illustrations) and set your
level so there are at least three indicators
illuminated for normal program level, with an
occasional move to the fourth indicator. The
fifth and biggest indicator denotes clipping –
watch out! If you see clipping, choose a lower
pad setting (for example, from -10 to -14 dB).
Transmitter PAD Adjustment
(See Fig. 4c, 4f & 4g)
1. Use the Transmitter Select button to scroll
through functions until PAD flashes in the
Transmitter LCD.
2. Use the Up or Down buttons to select the
desired setting. Selection is stored after 3
seconds of inactivity.
3. Check to see if the receiver’s Audio Level
Meter stays out of the Clipping Zone.

FIRST-TIME BATTERY CHARGING
Your Sabine Tr ue Mobility® transmitter
comes with one or more rechargeable
NiMH batteries. For best results, charge
the battery for at least 8 hours before
using it for the first time. Please note
that the full charging potential of the battery will be achieved after the first 5
charging cycles have been completed.
NiMH rechargeable batteries are highly
resistant to “memory effect,” which affects some other rechargeable batteries. The included NiMH batteries will provide more lifetime charges and longer
battery life for each charge than many
other rechargeable batteries.
Sabine rechargeable battery advantages. Here are several more good
reasons why you can feel more confident about using rechargeable
batteries:
1. All transmitters report two types of battery status information. The
first report is the all-important voltage the battery is supplying. Second, you’ll know how long the battery has been in use (battery run
time hours). Each receiver channel also receives telemetry information from its associated transmitter, regarding the battery voltage, and displays the information in the receiver LCD (see figure
5b). When the voltage reaches a level indicating an estimated 30
remaining minutes of useful battery life, both transmitter and receiver automatically flash warnings in their LCD displays. As an
alternative means of anticipating battery depletion, you can check
the number of hours of use, by checking the transmitter LCD display (see Section 4.2.2 and figure 4g), or the Remote Control Software.
2. The handheld microphone clip that we provide with each handheld
transmitter not only holds the microphone — it also can double as
an unobtrusive charger housing. Anytime the mic is parked in the
clip (and the clip is connected to the charger power supply), the mic
is being charged. As an additional safety margin against battery
failure, the mic placed in the powered clip gets its power from the
charger, not the battery, so it will work perfectly even if the battery is
completely dead.
3. Sabine’s intelligent charger circuitry detects the type of battery in
place within the battery compartment, and automatically turns off
the charger if the battery is not compatible with the charger.
4. The Tireless Wireless™ Charger detects when a battery is fully
charged, and turns off the charging cycle.
5. The Tireless Wireless™ Charger prevents futile attempts to resuscitate dead batteries — if the battery is unresponsive, the charging
cycle is stopped.
6. Beltpack and handheld batteries can be recharged without removing them from the transmitters. Just connect charger plug to the
transmitter jack (see Fig. 4l).
NOTE: In the “most discharged” battery condition, a full recharge may
take up 8 to 12 hours depending on the mA value of the AA batteries
used with the handheld and beltpack transmitter. The charging system
will charge a batteries with a mA value of up to 2400. When in doubt,
charge the batteries overnight. Sabine’s battery-protection circuit will
shut the charger down when charging is completed.

Transmitter Operation
4.2.4.2. Charging Your Batteries
Equipment Connections. Each SW75T or SW70H1 transmitter comes
equipped with an SWC-POWR Tireless Wireless™ plug-in charger (see
Fig. 4l). In addition, each SW70H1 comes with its own battery-charging
mic clip (SWC70-CL). The SWC-POWR charger can be plugged directly
into either the transmitter or into the clip. A Sabine rechargeable battery
(SWBC1) will charge whenever the mic clip is connected to the Sabine
SWC-POWR charger and the handheld is properly placed within the
mic clip.
Charging Indicators. Much like your cell phone, the transmitters will let
you know the charging status of the battery. When the battery is charging, the battery meter will flash to indicate the relative level of the charge
— one, two, three or four elements will flash (see Fig. 4i).
Once the battery is fully charged, all four elements in the battery meter
will flash. This indicates that the charging circuit is no longer on (see
Fig. 4j).
NOTE: The right-side indicator segment will flash for several minutes
when charging is first attempted (see Fig. 4h). The lower the battery
level, the longer this initial “testing/not charging” flashing sequence will
continue. During this time, the Tireless Wireless battery circuit is evaluating the suitability and charge status of the battery in place. When it has
completed its evaluation, it will either commence the progressive flashing depicted in figure 4i (CHARGING), or continue to flash (TESTING/
NOT CHARGING). All segments flashing in unison signifies that the
battery is fully charged (see Fig. 4j).
These same indications will also be displayed on the receiver LCD,
and on the Remote Control Software screen.
NOTE: The Tireless Wireless battery charger will only charge NiMH
rechargeable batteries. If you place any other kind of battery in the
transmitter, and then attempt to charge it by connecting the charger, the
Tireless Wireless circuit will detect the type of battery and
will not begin
charging. Again, the battery indicator on the transmitter will flash the
right-side element indicating testing/no charging (see Fig. 4h).
Fig. 4h: TESTING/NOT
CHARGING
Right-side battery indicator
segment will flash to indicate
that the battery is being
tested. This occurs prior to
charging a NiMH battery and whenever a nonrechargeable battery is placed on charge.
Charging is not occuring when indicator lights
in this fashion.
Fig. 4i: CHARGING
Battery indicator segments
will flash progressively starting from the relative charge
state of the battery. This example depicts a fully discharged battery being charged. As the charge
progresses, left-side segments will remain visible as right side segments continue to flash,
until all segments are visible. At that point, all
segments will flash on and off in unison (see
Fig. 4j).
Fig. 4j: FULL CHARGE
Battery indicator segments
will flash in unison to indicate that the battery is fully
charged.
NOTE: Battery can be left
connected to the charger and will receive periodic maintenance charging.
Battery Warnings. When the transmitter battery voltage drops below a
critical threshold, the battery icon (which normally displays the voltage
level) will begin to flash. This will occur on the transmitter and receiver
and is an indication that you need to replace the battery, or charge it by
placing the handheld mic in the charger clip. NOTE: Microphone will still
transmit audio when placed in clip. Alter natively, you can connect the
charger directly to the transmitter using the built-in charger jack located
on the side of the beltpack transmitter and near the antenna on the
handheld transmitter (see Fig. 4l). If the battery is not changed or recharged, the transmitter will eventually turn off (see Fig. 4k).
NOTE: When the battery has reached
a specific discharge level, the transmitter will automatically
turn off, and the transmitter LCD will display
the message at right.
