General
The TRX900 ( /AA) has an unbalanced microphone input accessed through a 3-pin micro-LEMO connector. You
can use an unbalanced dynamic microphone or a powered lavaliere. It is recommended that you use 3-wire
lavalieres with separate pins for ground, audio and power.
When using a Line-level input, an inline pad is required on the standard dynamic microphone input cable (XLR-3 to
3-pin micro-LEMO).
When using a phantom powered microphone with the TRX900 ( /AA), you must use an external 48 VDC power
supply. The TRX700 and TRX992 are the only Zaxcom transmitters that include a 48 VDC phantom power
supply.
NOTE: Once upon a time, the Denecke 48V power supply could damage the now discontinued Goldline
transmitter‟s preamp. This is NOT the case with the TRX900 ( /AA).

Chapter 1_______________________________________Zaxcom Digital Wireless System User’s Manual
Battery Installation
Each unit may require one to four batteries.
CAUTION: Always observe the correct battery polarity. The negative contact on the battery is always
connected to the spring contact.
Never use any battery that is missing insulation on its body. If you do, it can cause a short circuit in the battery
compartment, causing damage to the unit.
Battery Life
IMPORTANT: If operating using internal batteries, it is recommended that you use only Lithium or
rechargeable NiMH. Any other battery chemistry including Alkaline and Ultra batteries have a substantially
reduced runtime compared to Lithium or NiMH cells. This is true for all Zaxcom units.
External Power
Some of the units can be powered from an external power source. The external power connection is a 2.5 mm
(0.1”) barrel connector. The center pin is positive. The connector for the receiver (761K) is longer than the
connector for the STAxxx and IFB100 (760K). The 760K will not work in any of the receivers.

Table 1-4 Audio Frequency Block Information
IMPORTANT: As of 12 June 2009, the USA has phased out analog television. As a result, frequencies between
698.0 and 806.0 MHz are no longer available for use in the USA.
Only the frequencies in one specific block are available to a particular transmitter and its associated receiver.
Coordinate with your dealer or Zaxcom to determine which block(s) are the best to use in your area(s).
Remote Control, Timecode and IFB Feed
If the optional IFB feed and IFB remote control options are included, their frequency range is:
Current model for use Worldwide: 2.403 to 2.475 GHz
Antenna Cable Selection
When selecting a cable to use, it should be as short as possible. When using standard cable, the recommended
length should not exceed 10 feet. However, if greater than 10 feet is needed, a very low loss cable should be used.
For maximum performance, use only high quality 50-ohm coax cable and only as much as is required, otherwise
the receiver‟s sensitivity may suffer.
When permanently installing cables, use ½” Andrew heliax (http://awapps.commscope.com/catalog). Using
heliax cable, a run of 100 feet (~ 30.5 meters) can be achieved without significant power loss.

Mix Ratio
This fader controls the ratio between the audio coming directly from the mic and audio coming from the IFB feed
and is enabled when you set Earpiece Source page {p.28} to IFB MIX ALL.
NOTE: If you choose to mix the audio with the IFB return audio you will hear phasing. The reason is the slight
delay in the transmission process before it gets to your headphone. That delayed IFB audio, in concert with
the audio coming directly from the mic, is what causes this phasing, and is totally normal.
Headphone Fader
This fader controls the volume level to the 1/8” headphone jack. Before putting your headphones on, be sure to
turn „OFF‟ (full counter-clockwise) the headphone volume.
Media Slot
This slot holds a MiniSD card for local recording and is protected from accidental ejection by a guard bar. To
insert a card, with the screen facing you, turn the card so the finger contacts are facing you and down toward the
slot. Insert it into the slot and press it down until you here a slight click. To remove it, press it in until you hear
the same click again.
Transmitter Antenna
The transmitter has a gold plated SMA connector. You should periodically check that the connector is still
securely tightened.
Unit Power Switch
This switch is not as low profile as those on the TRX900 ( /AA). Since this unit is not being used on talent, it
should not be a problem.
IFB Antennas
CAUTION: These antennas are located behind the Zaxcom label on the front face. Don‟t place anything in
front of this area that could block reception. Also, don‟t allow anything to press in on this area, the antenna
and/or receivers could be damaged.
Battery Slot
The VPX battery slides into the battery opening in the bottom of the unit. The battery can only seat in one
direction, with the red latch away from the XLR connector. Be sure to press it in far enough that it clicks (locks)
into place. To remove the battery, press the red edge inward and gently pull the battery out.
Phantom Power Switch & Mic/Line Switch
See Fig 2-3 to get your bearings. Looking inside the opening for the battery, behind the XLR-3F, you will see a red
base and two black switches sticking up from it. The closest switch is for phantom power. Pushing it away from
the bottom is „ON‟. The farthest switch is for Mic/Line-level selection. The closest position is for Line-level.

Audio Gain page
GAIN 20dB
Page purpose: This page adjusts the mic gain, using the INC or DEC key.
Parameters: (Valid range:
0 to 52, Value step: 2)
When audio is applied to the microphone input, the LCD indicates the signal strength using a bar graph displayed
horizontally from left to right (-40 to 0 dBFS). The gain should be set so that the meter is peaking between -20
and -10 dBFS. This is about half way between the -20 and 0 dBFS markings below the meter. If no microphone is
connected, the bar graph remains blank.
The transmitter features a digitally controlled analog limiter that is situated before the A/D converter. This
prevents the A/D convertor from clipping by automatically attenuating the mic gain when excessive audio is
detected.
The limiter engages before the signal exceeds the digital capabilities of the signal path. The limiter activates at -6
dBFS. The gain level should be set low enough to prevent it from engaging, even when talent is screaming.
Audio Transmitter Frequency page
TXFREQ 581.6
Page purpose: This page sets the audio transmitter‟s center frequency.
Parameters: (Valid range: (see Table 1.4 {p.14}), Value step:
.1)
The transmitter can operate on any frequency between 518.0 and 870.0 MHz but your unit can only operate in its
assigned block within this frequency range.
There is a one-second delay while moving to a new frequency. If the frequency is changed quickly, the transmitter
remains quiet until the desired frequency has been selected.
When operating multiple transmitters in the same area, it is recommended that you use at least 1 MHz separation
between radios. If audio frequencies are difficult to obtain, the minimum spacing can be as low as 0.6 MHz while
using US modulation, or 0.5 MHz while using European modulation. Using a large frequency separation between
each transmitter aids in their clear reception. Maintaining a distance of 20 feet or more between transmitter and
receiver also aids in reception when several transmitters are used at the same time. This will prevent any
transmitter from de-sensing any of the receivers.
Frequency planning programs, which are used to prevent intermodulation problems, are not needed when using
the Zaxcom Digital Wireless system. However, if regular FM wireless mics are being used near the Zaxcom
system, you must plan your frequency assignments to prevent intermodulation. When two FM transmitters come
close to each other, they can produce interference on adjacent frequencies. Since this interference is transmitted
over the air, there is no way for a Zaxcom receiver to reject it. However, Zaxcom transmitters do not suffer
from this problem.

Limiter page
LIMITER: OFF
Page purpose: This page enables/disables the limiter function.
Parameters: [OFF] \ [ON]
NOTE: This page applies to the mic input only. It does not come into play for the STAxxx.
When the input signal is too high for the gain setting, it is clipped and results in distortion and popping. The limiter
is used to prevent clipping by beginning to engage around -10 dBFS. When using a microphone, normally you
would enable the limiter. However, if the input signal is coming from a mixer that is using a limiter, you should
disable this limiter.
Since it is implemented in the digital domain, the automatic limiter may engage even when you don‟t hear any
substantial audio. The purpose of the limiter is to prevent the mic preamp from over-driving the A/D converter,
30
Zaxcom Digital Wireless System User’s Manual_______________________________________Chapter 2
so the limiter operates on audio before it has been processed by the highpass filter. If there is a massive amount
of low frequency audio content being filtered out, such as wind noise, you may hear the effects of the limiter
without hearing the audio that caused the limiter to engage. If this occurs, the gain is set too high and you must
reduce it to below the level that triggers the limiter.

Parameters: [NORMAL
(OFF)] / [2 TXERS (ON)]
To use this function, you will need a second IFB100 that is also connected by audio cable to your cart and placed
some distance away in the direction you expect Talent to travel. Set the frequency of this second IFB to 2 MHz
(+ 0.002 GHz on the IFB Frequency page {p.62}) above the first unit. Also be sure to set the IFB Frequency
page {p.32} on the Audio Transmitter(s) (i.e. TRX900) to the lowest frequency assigned to the two IFB100s.
In operation, the first IFB100 will be closer to (or on) your cart and the second IFB100 will be some distance away
to cover the area you anticipate using. While the audio transmitter(s) (i.e. TRX900) is within range of the first
IFB100, it will be receiving IFB audio on that lower IFB frequency. Once the TRX900 has gone out-of-range of the
first IFB and gone into-range of the second IFB, the TRX900 IFB receiver will switch to receiving on the frequency
assigned to the second IFB. If over time, the unit moves out-of-range of the second IFB and back into-range of the
first IFB, the TRX900 will once again start receiving on the first IFB‟s assigned frequency.

Dynamics comprises both a compressor and an expander, which operate jointly.
The compressor in Dynamics can perform mild or extreme compression and features a soft knee for more
transparent operation. The expander in Dynamics can perform subtle or extreme noise reduction.
Note that the Dynamics processing is done before the existing Expander (which is still functional). Thus, the
expander can be used as a stand-alone noise gate while the dynamics can shape the sound as desired.

Security Code Part 1 (ID1) and Security Code Part 0 (ID0)
On this page, 2 three-digit numbers are entered. These two numbers are formed into a single six-digit security
code. This code is your security key for this transmitter. An identical code must be entered into the associated
receiver for the audio to be properly decoded.
Enabling this function is useful when sensitive information must not be made public. Standard FM wireless
transmitters can be picked up using scanners and other electronic devices. Unless a Zaxcom receiver is used, even
an uncoded transmitter signal cannot be picked up using a scanner.
The six-digit security code provides a total of 16,777,216 possible choices.
If a Zaxcom receiver has been programmed with a security code, it will also continue to receive an uncoded
transmitter (both ID#0 and ID#1 set to 000). Since the receiver has to check for two possible code situations, a
slight performance penalty may be incurred during long-range reception. To avoid this, it is highly recommended
that both the transmitter and receiver codes be set to 000:000 (uncoded) when high security communication is
not required.

Chapter 3 – Recording Audio using the Digital Wireless System Transmitters
The ability to record audio at the transmitter is an optional feature, which must be configured by Zaxcom when
purchased. If the necessary configuration steps have not been performed, none of the recording features will be
available. It is possible to have this capability added to an existing unit for a nominal charge. Contact Zaxcom for
addition information.
Recording Format
The MiniSD card is formatted using the FAT32 file system. While recording, the transmitter places all recorded
audio in a single file on the media.
The FAT32 file system can be read on both Windows and Mac OS computers. However, the single file generated
by the recorder can only be understood by the Zaxcom Transfer and Conversion utility {p.68}. It converts the
file into a format (Broadcast Wave Format = BWF), that is useable in Post. This utility is available to anyone for
free from the Zaxcom website.
Recording Mode
The audio can be recorded in Loop Recording mode or Non-Loop Recording mode.
In Loop Recording mode (indicated by LREC in the Pacifier page {p.26}), as the card fills-up, it eventually
loops back to the beginning of the card and records over the oldest material. To prevent audio from being erased,
do not exceed the recording length of the media (see Table 3.1 – Available Recording Time {p.40}).
In Non-Loop Recording mode (indicated by REC in the Pacifier page {p.26}), as soon as the card is full,
recording ceases and the screen displays FULL.
Battery Life
While recording audio, a slight decrease in battery life occurs. The battery drains about 5% faster while recording,
than a non-recording transmitter. Under typical situations, the unit‟s battery life will be reduced from
approximately 5 hours to 4 hours & 45 minutes.
Media Capacity
You can use MiniSD cards ranging in size from 128 MB to 16 GB. The 16 GB MiniSD card records a single track of
audio for 96 hours without erasing any recorded audio on the card. Available recording times are as follows:
MiniSD Size

IMPORTANT: The unit will NOT record onto the card if it was not present when the transmitter was
powered up, if it was removed while the power was „ON‟ or if the LOW BATTERY page is being displayed. If
the card was ejected while the power was „ON‟, the card must be reinserted before its power is cycled, in
order to resume recording.

Table 3-2 Recorder LED Indications
Transmitter Recording Operation
This section describes the steps necessary to record on the transmitter.
Formatting the MiniSD Card
Many MiniSD cards are sold preformatted; however, you must reformat it in the recorder prior to recording on it.
Only cards formatted in the transmitter will work correctly.
To prepare a MiniSD for use, or to erase the contents before reuse, perform the format procedure on the Media
Erase & Format page {p.32}.
Upon completion of the formatting process, the following files remain on the card (example based on a 2GB card):
SN01752
ZBLK0000.ZAX
ZBLK0001.ZAX
ZDIR.ZZZ
DELETE.ME
(This folder‟s name initially defaults to the transmitter's serial #, thereafter
it is the Track Name {p.37} entered in the Extended Menu.)
(size = 1,048,576 KB)
(size = 932,684 KB)
(size = 538 KB)
(size = 512 KB)
The ZBLK****.ZAX files store the recording segments, and the ZDIR.ZZZ file stores metadata about each
segment (i.e.: pointer into the .ZAX file, associated start timecode, transmitter name, etc.)
The DELETE.ME file can in fact be deleted. Doing this frees up enough room for a copy of the firmware.
CAUTION: Do not delete any other files from the card. Doing so will prevent it from working correctly. If for
some reason you proceed to delete the wrapper files, follow the instructions To recreate the wrapper files
{p.33}.
NOTE: If you move a transmitter to another actor and enter the new actor/character name, the folder name will
remain the same and any audio from the new actor will be stored in the same folder. The metadata will
contain the correct name.
IMPORTANT: If it is important to you that the Track Name folder is correct, prepare a card for each
actor/character and have it follow each actor. This does not eliminate the need to change the track name, so
the correct name appears in the metadata.
Current Timecode and Frame-rate Display
The current timecode generator value and frame-rate appear on the Timecode Frame-rate page {p.28}.
Jamming Timecode into the Transmitter
While the transmitter is being jammed, it identifies the timecode rate and type, and sets itself to that rate.
NOTE: The transmitter‟s timecode accuracy is approximately 1 frame in 6 hours (1.54 PPM).
Jamming timecode on the transmitter starts a new recording file. The Zaxcom conversion utility starts the
transfer and conversion process at the point where the transmitter‟s timecode was jammed.
NOTE: The transmitter does NOT continue to keep timecode when it is powered down. Every time its power
is cycled, it will be necessary to jam its TC generator.
41
Chapter 3_______________________________________Zaxcom Digital Wireless System User’s Manual
Manually Jamming TC with a Cable
Timecode can be jammed into the transmitter by connecting the timecode source to the microphone input or
using the stereo adapter. When timecode is connected, it takes the transmitter approximately three (3) seconds
to recognize the TC input. The screen display TIME CODE followed shortly by JAMMED when it is
recognized. When the word JAMMED disappears, the timecode input source can be disconnected and normal
operation can be resumed.
When using the mic input connector with a Mic-level source, the audio level of the timecode needs to be between
-30 and -10 dBFS on the transmitter‟s meter. Any level above -10 may cause clipping, which will prevent proper
reading of timecode.
When using the mic input connector with a Line-level source, a Line-level to Mic-level cable should be used to
attenuate the timecode signal out of a generator to the correct audio level.
When using the Line-level input connector (STAxxx/TCA100) with a Line-level source, a non-attenuating cable
should be used.
In the transmitter {TRX9xx}, (Extended Menu) or recorder {ZFR100}, (Standard Menu):

Tighten the two screws, alternating between them, until the adapter and transmitter are tightly connected.
CAUTION: Do not over-tighten the screws.
Connect a Line-level source to the TA-5M connector. The Line-level input needs to be between -6 and +8 dBu.
Adjusting the Input Level
Output tone from a mixer and adjust the 2 input pots so the meter on the LCD screen is at a level of -20 dBFS.
The stereo adapter does not have a limiter function so it is important not to overdrive or clip the input of the
stereo adapter.
43
Chapter 4_______________________________________Zaxcom Digital Wireless System User’s Manual
Powering the STAxxx
Connection of 12 VDC power to the stereo adapter is optional. If no power source is connected to the STAxxx,
it operates from the transmitter‟s internal battery.
Using an External Power Source
When the 12 VDC input is connected to a power source, it supplies power to the transmitter when its power
switch is in the „OFF‟ position.
If batteries are installed in the transmitter and external power is connected, the unit will not be able to power
down unless an external power switch is available to remove the external power.
Using the STAxxx to Power the Transmitter
The adapter can be used to power the transmitter while it is in Mono mode and using a Mic-level input.
The Audio/Timecode Output Connection
The audio output connection is used to monitor the audio functions of its host unit or to allow timecode to pass
through the STAxxx. The transmitter‟s output setting (Timecode Output Enable page {p.34}) determines if
audio or timecode is sent through the output.
Timecode Input
The timecode input is used to jam the transmitter‟s timecode generator. If the auto-load function (Timecode Jam
Mode page {p.33}) is enabled, the timecode input of the stereo adapter can be used.
Operation of the STAxxx
For the stereo adapter to operate, the transmitter must select the stereo setting (Audio Transmission Format
page {p.31}) and external ADC (ADC Location page {p.36}) must be selected.
Host Unit functions
Selecting the stereo setting causes the transmitter to combine the two input signals together and transmit them on
one frequency. The ADC selection: INTERNAL – selects the internal mic input, EXTERNAL – selects the
stereo adapter audio.

Powering the Receiver
The ENG Diversity Receiver can be powered by batteries installed in the unit or using an external 9 to 18 VDC
source.
Use the front panel power switch to select: internal power, external power or no power.
Internal Batteries
Four AA batteries are used to power the receiver. Use either Lithium or Nickel Metal Hydride (NiMH) AA
batteries. While alkaline batteries may be used, they will only power the unit for a short time (~30 to 60 minutes).
NiMHs will last up to 6 hours, while Lithiums will last about 10 hours.
To use internal batteries, set the power switch to the INT position.
The 4 AA batteries are accessed by pressing on the battery door while sliding the door away from the center of
the unit.
External Power Source
An external 12 VDC source can be used to power the receiver for an extended time. Set the front panel power
switch to the EXT position while using an external power source. The receiver does not automatically switch to
an internal power source if the external power source is lost. You must manually change the front panel power
switch from EXT to INT, to power the unit from the internal AA batteries.
The receiver external power can range from 9 to 18 VDC. However, if the voltage drops below 10 VDC, the
audio quality will degrade.
Connections
This section describes the physical connectors on the receiver. The power connector was described in the
previous section.

Chapter 5_______________________________________Zaxcom Digital Wireless System User’s Manual
Audio Output Connector
The XLR connector provides the receiver‟s output. A stereo receiver has an XLR-5M connector; the mono
receiver has an XLR-3M connector. You can select either Line-level or Mic-level output using the switches on the
rear of the receiver. In the MIC position, the output level is -42 dB. In the LINE position, the output level is -2
dB. There is 20 dB of system headroom.

Antenna Connectors
The front of the receiver has two SMA connectors, intended to connect to external 50-ohm log-periodic (“Sharkfin”) or whip antennas. For best performance, keep any transmitters at least 3 feet (1 meter) away from the
antennas. This is because strong radio frequency sources reduce the receiver‟s sensitivity. The receiver is
optimized for properly tuned external log-periodic antennas. When whip antennas are used, there is a noticeable
reduction in the receiver‟s range. You should periodically check that the connector is still securely tightened.

Powering the Receiver
An external 12 VDC source can be used to power the receiver. This power source can range from 9 to 18 VDC.
However, if the voltage drops below 10 VDC, the audio quality will degrade.
Connections
This section describes the physical connectors on the receiver.
Audio Output Connector
The XLR-3M connector provides the receiver‟s output. Each receiver has two, one for each channel, and they
output at Line-level (+4 dBm). There is 20 dB of system headroom.

Antenna Connectors
The rear of each receiver has two BNC connectors, intended to connect to external 50-ohm log-periodic (“Sharkfin”) or whip antennas. For best performance, keep any transmitters at least 3 feet (1 meter) from the antennas.
This is because strong radio frequency sources reduce the receiver‟s sensitivity. The receiver is optimized for
properly tuned external log-periodic antennas. When whip antennas are used, there is a noticeable reduction in
the receiver‟s range. You should periodically check that the connector is still securely tightened.

Page purpose: When you power up the unit, this page appears and displays the following information:
 antenna being used,
• signal strength,
• audio level
 transmitter limiter status
• receiver reception format
• receiver battery capacity
 transmitter recorder status
• transmitter battery capacity
Parameters:
Character 1 – Antenna
Displays which antenna is being used. This character is always either an
A or B.
Characters 2 and 3 – Signal Strength
Two vertical bar graphs are displayed representing the signal strength at the antennas. A strong RF input level
is shown using a checkered pattern. This is the ideal signal strength.
Character 4 – Audio Level
When this character turns into a checkered pattern, the transmitter‟s limiter is engaging due to excessive audio
input levels. If this occurs, reduce the audio gain on the transmitter. This ensures the highest level of
unprocessed audio quality.
Characters 5 and 6 – Receiver Information
The meaning of these characters changes based on when you look at them. If you turn „ON‟ the receiver after
the transmitter, it will display the Reception Format for about one second before it starts displaying the
Receiver‟s Battery Level. At all other times, only the Receiver‟s Battery Level is displayed.
Reception Format
 us – US mono format #0
 eu – European narrow-band format #1
 st – US stereo format #2
Receiver Battery Level
This ranges from R9 down to R0. When the level reaches R0, the receiver has only a few minutes
before its battery is depleted.
Characters 7 and 8 – Transmitter Information
Character 7 indicates the recording status of the transmitter ( R or S).
is not recording (stopped).
R means it is recording and S means it
Character 8 indicates the transmitter battery‟s level of charge and ranges from 9 to 0. When the level reaches

Parameters:
The screen initially displays Scan1234, where 1234 is the currently selected frequency (xxx.x MHz).
Starting a Scan
Press the INC key to start a scan. The receiver searches every possible channel.
A full scan takes about 10 seconds and the receiver displays the quietest frequency once the scan has
completed.
Accepting the Frequency
Press the DEC key to load the selected frequency into the receiver.
Discarding the Frequency
Press the MENU key to discard the selected frequency. The receiver exits to the Pacifier page {p.52} after
discarding the frequency.
Blocking Frequencies with RF Interference
Press the INC key to restart the scan. However, when the scan restarts, instead of performing an entirely
new scan, it averages the current and previous scans. Frequencies that are temporarily occupied are
remembered in the final selection, allowing the receiver to block frequencies that contain intermittent RF
interference.
Starting a New Scan
Repeatedly press the MENU key until you have stepped all the way around the menu back to the Audio
Receiver Frequency Scan page {p.53}.
Best Practice: Scanning for a Low Noise Frequency
The easiest way to remember the proper way to scan is to push the keys from right to left:
1. Repeatedly press the MENU key until SCAN is displayed.
2. Press the INC key to start the scanning process. Ensure the transmitter is „OFF‟ before starting the scan.
3. Press the DEC key to load the selected frequency into the receiver. The menu advances to the next item.

Turn all transmitters „OFF‟ and perform a couple of scans.
Accept the quiet channel by pressing the DEC key.
Turn „ON‟ the first transmitter and tune it to this channel.
Place the transmitter at least 20 feet (6 meters) away from the scanning receiver.
Using the next receiver, perform another pair of scans.
Repeat steps 2 thru 5 for each addition transmitter/receiver pair.
NOTE: At any time in this page, the MENU key may be pressed to exit. This will also clear out any change and
revert to the previous selection.
Since the most recently selected frequency is now occupied, the next receiver to perform a scan finds the next
quietest frequency. Repeat this procedure for each additional transmitter. This procedure assumes that all of the
transmitters will be operating in the same block.

If a Zaxcom receiver has been programmed with a security code, it will also continue to receive an uncoded
transmitter (both ID#0 and ID#1 set to 000). Since the receiver has to check for two possible code situations, a
slight performance penalty may be incurred during long-range reception. To avoid this, it is highly recommended
that both the transmitter and receiver codes be set to 000:000 (uncoded) when high security communication is
not required.

Chapter 6 – IFB100 IFB Transmitter
This chapter is intended to quickly familiarize you with the functions of the Zaxcom IFB100 IFB transmitter and
was written based on firmware version 6.08.
Getting to Know Your IFB Transmitter
It is a 100 mW RF transmitter designed to be used with the Zaxcom Digital wireless system. The IFB100 uses a
digital spread spectrum signal to send and receive IFB audio, timecode and remote control signals. By using spread
spectrum technology, the IFB is immune to interference. IFB audio has a range of approximately 150 feet,
timecode and remote control commands have a range of approximately 500 feet.
In locations where multiple IFB100 units are used, you can set each TRX9xx or ZFR100 to a specific IFB100 unit.
The IFB100 contains a simple menu driven interface with minimal physical keys and connectors.

Zaxcom Digital Wireless System User’s Manual_______________________________________Chapter 6
Setting Up the IFB100
This section describes setting up the IFB100 for the first time.
Power Requirements
The IFB100 requires an external power source (8 to 18 VDC). Ideally, the source should be 12 VDC. Normal
current draw is 125 mA at 12 VDC but a power supply needs to be capable of supplying at least 1 amp.
Audio Input
The two channel balanced audio input on the IFB100 has a TA-5M connector. The input audio range is -8 dBu to
+4 dBu. You can configure the IFB100 to transmit a single channel or a mix of the two input channels.
IMPORTANT: When using the IFB100 for IFB audio transmission, an external 2.4 GHz antenna is strongly
recommended. When using the supplied antenna directly mounted to the transmitter, it is possible the RF
signal will interfere with the audio connected to it. The result being a 1kHz tone added to the audio being
sent out. The supplied antenna is recommended for timecode and remote control transmission only.
Adjusting the Input Audio Level
The input audio level is preset by Zaxcom at +4 dBu. However, this level can be adjusted using the trim pots
located on the outside of the unit. See the Side View in Fig 6-1 {p.58}.
Timecode
Unless an external timecode source is present, the IFB100 outputs free-run timecode. When connected to an
external timecode source, the timecode generator syncs with it.
IMPORTANT: A stereo plug is required for external timecode sync. Do NOT connect to the ring on the plug.
You cannot use a mono plug. A mono plug will not destroy any components but it will short out the signal.
IFB100 Configuration Menus
The IFB100 uses a series of menus for configuration. These menus are similar to other Zaxcom wireless devices
and behave in a similar fashion.
There are nine Standard and thirteen Extended menu pages, as follows:

Page purpose: This page sets the transmit frequency for the specified TRX9xx.
Parameters: (Valid range: (see Table 1.4 {p.14}), Value step: .1) The frequency range is based on the
frequency range selected in TV Channel Minimum page {p.65} and TV Channel Maximum page {p.65}.
The top example is what you should normally see. The bottom example is what you see if you have selected the
ALL choice for Unit Code. Since it‟s a really BAD idea to command all transmitters to start using the same
frequency, this warning basically reminds you to choose a specific transmitter.
While you are changing the frequency on the display, the command is not sent to the selected TRX9xx transmitter
until you stop on a specific frequency for longer then 1.5 sec. This prevents the TRX9xx unit from transmitting on
all channels between the old and new frequencies. The transmit counter, bottom line right three digits, will
increment and an asterisk (*) will blink, for each message sent (several will be sent each time you press the INC or
DEC button). If you are at the extreme edge of your range, you may need to take additional actions to get the
change to take place (i.e. re-orient your antenna, have talent move closer, etc.).

separation between channels is necessary when using the Zaxcom Voting System (ZVS).
If the ZVS is enabled, you need to allocate four adjacent channels, 2 MHz apart, for the IFB100s. For example, the
ZVS would use 2.403 GHz, 2.405 GHz, 2.407 GHz and 2.409 GHz. This makes 2.411 GHz the next channel
available for another ZVS group.
Using 2 MHz spacing, the IFB100 can simultaneously support 36 IFB channels.
Selecting the frequency
If interference is encountered, the range of the system is affected. If the range is less than 150 ft., go to a different
channel at least 30 MHz away from the interfered channel.
There are many devices that use the 2.4 GHz band. The IFB100 should be able to operate interference free while
other devices share the band. It is suggested that when operating in a new location that a range test be conducted
before the unit is used for a production.

30 to 220Hz, Value step: 10)
Limiter page
LIMITER: OFF
Page purpose: This page enables/disables the limiter function.
Parameters: [OFF] / [ON]
Since it is implemented in the digital domain, the automatic limiter may engage even when you don‟t hear any
substantial audio. The purpose of the limiter is to prevent the mic preamp (connected to the TA-5M) from overdriving the A/D converter, so the limiter operates on audio before it has been processed by the highpass filter. If
there is a massive amount of low frequency audio content being filtered out, such as wind noise, you may hear the
effects of the limiter without hearing the audio that caused the limiter to engage. If this occurs, the gain is set too
high and you must reduce it to below the level that triggers the limiter.
IFB Format page
IFB FORMAT:
LOW Q
Page purpose: This page controls the quality of the transmitted IFB signal.

Chapter 10 – Wiring Diagrams
NOTE: All of the diagrams in this chapter show the solder side of each connector.
NOTE: The following 3-pin micro-LEMO connectors mate with the microphone connector:
 FGB.00.303.CLAD.22
 FVB.00.303.NLA
– has a latch with a pull release. (HIGHLY recommended for RFI prevention)
– has a latch with a twist release.
IMPORTANT: The reason for the break on serial #, transmitters before #1315 do not have a bias resister
installed. To have a mic work with them it is necessary to include it.
CAUTION: When wiring a microphone for the TRX900 ( /AA), the microphone shield/ground must be
connected to the LEMO shell as well as the correct pin on the microphone connector itself.
This connection stops RF energy from entering the body pack through the shield of the microphone cable. If this
happens, the user can experience RF dropouts at any distance from the receiver. Routing the microphone
cable away from the TRX900 antenna is a temporary fix if this effect is noticed.
Use of the push-in type LEMO connector, rather than the screw in type, is advised as it is easier to make the
ground connection to the connector shell.
TRX900 ( /AA) Microphone Cables (after serial # 1314)
NOTE: Before building cable(s) using these diagrams, PLEASE REVIEW the information at the top of this
chapter.

Chapter 11 – Firmware Information
Firmware
Each unit is shipped with the latest firmware version installed. For the TRX900, TRX900AA, TRX992, TRX700,
TRX800 and IFB100, as newer firmware becomes available, it can be downloaded from the Zaxcom website
(http://zaxcom.com/software_up dates.htm). For the RX900 (M/S) and RX4900, the unit must be returned to
Zaxcom, Inc to upgrade its firmware.
Each time a unit is powered up, the firmware version number is displayed briefly on the LCD screen.
Advantages to Upgrading the Firmware
By upgrading the software, the range and feature set have and will continue to dramatically increase over time.
Zaxcom has a reputation for constantly adding additional features and user suggestions during the product‟s
lifetime. This ensures that your wireless system will perform better and better, the longer you own it.
Upgrading the firmware in each unit

Significant Change Reminders
Using Remote Control and Timecode while in HQ Mode (2009-06-03)
TX Version 6.08+
This version now allows receiving Timecode and the using Remote Control while High Quality Audio mode is
selected.
Using High Capacity SD Cards (2009-03-03)
TX Version 5.98+
A problem with using 4GB, 8GB and 16GB cards has been fixed. This change could possibly cause some older
cards to stop working. If you upgrade to this version and find that your brand of SD card no longer works, you
may need to use another brand of SD card to downgrade to an older version.
Note: large cards take longer to start up.
New IFB High Quality Mode in TRX992 (2009-01-29)
TX Version 5.92T+ IFB Version 5.92+
The user may select between high quality audio mode and normal mode.
Note: while in high quality mode, the wireless timecode and remote control features are not available.
New Receiver LCD module (2008-12-04)
RX x80+
A new LCD module has been incorporated into all of the receiver configurations.
NOTE: effective with serial # 1517.
Independent TRX992 Firmware version (2008-11-29)
TX Version 5.70T+
The TRX992 requires special software to make its enhanced IFB circuitry work properly. Make sure the firmware
program you load into the TRX992 always has a "T" suffix.
Left/Right Switch Mode (2008-11-24)
TX Version 5.68+
RX Version x83 or x78+
This new functionality allows the user to cause the audio to switch from the left to the right output channel on a
stereo receiver when a button is pressed on the transmitter. This allows the talent to talk to the sound mixer
without it being heard on air.
New IFB Audio Codec (2008-05-21)
TX & IFB Version 5.50a+
The IFB audio transmission format has changed. To maintain IFB audio compatibility, both the IFB transmitter(s)
and the audio transmitter(s) must be loaded with this version or higher.
Know Firmware Problems
Transmitters
 PROBLEM: Naming your transmitter “ZAXCOMSD” in the Track Name page {p.37}, will cause the Format
function in the Media Erase & Format page {p.32} to fail.
WORKAROUND: Don‟t do that.
 PROBLEM: The first audio segment is always timecode stamped with 00:00:00.
WORKAROUND: Go into record mode for a few seconds, after the card has been initialized. Any
recording after this point will have the correct timecode recorded in the file.

Modified
Low Power mode triggers a new experimental Low Power mode.
This mode is triggered if:
LED mode = "LOW POWER MODE"
TX Format = US (MONO)
IFBMODE = "OFF"
Timecode, IFB and Recording features are turned „OFF‟ in this mode
To change to Low Power mode:
1.
2.
3.
4.
5.
Added
Go to Extended Menu (hold MENU while powering up the unit)
Change IFBMODE to „OFF‟ (if you have that option)
Go to the LEDREVERSE screen (one of the last menu pages). The LEDREVERSE setting allows you to change the default color of
the LED. The LED should usually be green.
Change the setting to LED LOW PWR MODE while keeping the LEDREVERSE setting the same digit as it was previously.
If the conditions have been met, the unit will display LOW POWER MODE, IFB IS OFF when the unit boots up again and the LED
turns „OFF‟ when not in use. This setting should increase the battery life by over 15% depending on the chemistry of the batteries
you are using.

Zaxcom Digital Wireless System User’s Manual______________________________________Chapter 11
Version 5.00d: UNKNOWN
Added
Timecode wrap at 24 hours for non-jammed timecode setting using last recorded segment as TCjam
Fixed
a serious record bug that prevented the unit from going into record if the timecode had wrapped around the 24-hour mark.
===================================================================================================================
Version 5.00b: UNKNOWN
Added
Special super Low Power operating mode: It is triggered if:
LED mode = LOW POWER MODE
TX Format = US (MONO)
(NOTE: no timecode, IFB or recording is available in this mode)
Changed
battery meter table

===================================================================================================================
Version 4.99a: UNKNOWN
Fixed
IFB side autoload (would not go into STOP because it never really went into RECORD)
===================================================================================================================
Version 4.99: 2007-10-04
Added
support for RCR dual mic side adapter
Changed
stereo to always be ISO
Changed
FORMAT_EUNB to FORMAT_MONO_R
===================================================================================================================
Version 4.98: 2007-09-25
Fixed
IFB Autoload function (remote transport commands TXifb.NS_RemoteTPmode not being set)
===================================================================================================================
Version 4.97a: 2007-09-25
Changed
sector size from 32k to 16k (or less) for Digital Foci PhotoSafe (FAT16 vs. FAT32 problem)
===================================================================================================================
Version 4.97: 2007-08-31
Fixed
a serious bug regarding the RecoverOpenSegment feature. If the unit is powered down while in record, the next recorded segment could
begin at the start of the card, which would overwrite previous audio and make only that last recorded segment available.
The new ZaxConvert software (v5-97) fixes a minor problem with the RecoverOpenSegment feature and now appends the segment number (in decimal) to the end
of each generated WAV or MP3 file.
===================================================================================================================
Version 4.95: 2007-08-10
Added
IFB VOTING screen. Turn „ON‟ voting only if you have two IFB transmitters transmitting 2MHz apart from each other. If a receiver has
voting turned „ON‟ and it loses its IFB signal it will try to acquire an IFB signal on a channel that is 2MHz higher than its current RX frequency.
For example: set the IFB to receive on 2.403GHz and set up two IFB transmitters (far apart from each other) one at 2.403GHz and one at
2.405 GHz. The IFB receiver(s) will switch from one channel to the other if the IFB signal degrades. This feature dramatically increases the
IFB range when using two or more IFB transmitters.
Added
Safe Boot Mode feature. If the unit crashes after boot (and the battery is OK), hold the MENU and DEC keys while powering up. This will
turn „OFF‟ the IFB. An older unit may crash if IFB and STEREO are both enabled. There is a modification to the power supply board that will
fix this.

Added
LRSWitch mode – DO NOT USE WITH STEREO MODE. When used with TRX version 5-86 and higher, holding a (user selectable)
button on the transmitter causes the receiver‟s audio to move from the left channel to the right channel. This is useful for times when the
talent wants to say something private to the sound mixer without the audio being heard by an audience.

Chapter 14______________________________________Zaxcom Digital Wireless System User’s Manual
Chapter 14 – Zaxcom Warranty Policy and Limitations
Zaxcom Inc. values your business and always attempts to provide you with the very best service.
No limited warranty is provided by Zaxcom unless your Zaxcom Digital Wireless System Component (“Product”) was purchased from an
authorized distributer or authorized reseller. Distributers may sell Product to resellers who then sell Product to end users. Please see below
for warranty information or obtaining service. No warranty service is provided unless the Product is returned to Zaxcom Inc. or a Zaxcom
dealer in the region where the Product was first shipped by Zaxcom.
Warranty Policy
Zaxcom Product carries a Standard Warranty Period of one (1) year.
NOTE: The warranty period commences from the date of delivery from the Zaxcom dealer or reseller to the end user.
There are no warranties which extend beyond the face of the Zaxcom limited warranty. Zaxcom disclaims all other warranties, express or
implied, regarding the Product, including any implied warranties of merchantability, fitness for a particular purpose or non-infringement. In the
United States, some laws do not allow the exclusion of the implied warranties.
Return Material Authorization (RMA)
No Product may be returned directly to Zaxcom without first contacting Zaxcom for a Return Material Authorization (“RMA”) number. If it is
determined that the Product may be defective, you will be given an RMA number and instructions for Product return. An unauthorized return,
i.e. one for which an RMA number has not been issued, will be returned to you at your expense. Authorized returns are to be shipped prepaid
and insured to the address on the RMA in an approved shipping container. Your original box and packaging materials should be kept for storing
or shipping your Product. To request an RMA, please contact Zaxcom by telephone. There is an RMA form on the Zaxcom website. Please
fill out the form and return it with the Product for repair. Zaxcom will return the warranty repair via 2nd day UPS or FedEx at their discretion.
If overnight service is required, a FedEx or UPS account number must be provided to Zaxcom to cover the shipping expenses.
Warranty Limitations
Zaxcom‟s limited warranty provides that, subject to the following limitations, each Product will be free from defects in material and
workmanship and will conform to Zaxcom‟s specification for the particular Product.
Limitation of Remedies
Your exclusive remedy for any defective Product is limited to the repair or replacement of the defective Product.
Zaxcom may elect which remedy or combination of remedies to provide in its sole discretion. Zaxcom shall have a reasonable time after
determining that a defective Product exists to repair or replace a defective Product. Zaxcom‟s replacement Product under its limited warranty
will be manufactured from new and serviceable used parts. Zaxcom‟s warranty applies to repaired or replaced Product for the balance of the
applicable period of the original warranty or thirty days from the date of shipment of a repaired or replaced Product, whichever is longer.
Limitation of Damages
Zaxcom‟s entire liability for any defective Product shall, in no event, exceed the purchase price for the defective Product. This limitation
applies even if Zaxcom cannot or does not repair or replace any defective Product and your exclusive remedy fails of its essential purpose.
No Consequential or Other Damages
Zaxcom has no liability for general, consequential, incidental or special damages. These include loss of recorded data, the cost of recovery of
lost data, lost profits and the cost of the installation or removal of any Product, the installation of replacement Product, and any inspection,
testing or redesign caused by any defect or by the repair or replacement of Product arising from a defect in any Product.
In the United States, some states do not allow exclusion or limitation of incidental or consequential damages, so the limitations above may not
apply to you. This warranty gives you specific legal rights and you may also have other rights, which vary from state to state.
Your Use of the Product
Zaxcom will have no liability for any Product returned if Zaxcom determines that:

The Product was stolen.

The asserted defect:
1. Is not present,
2. Cannot reasonably be fixed because of damage occurring when the Product is in the possession of someone other than Zaxcom, or
3. Is attributable to misuse, improper installation, alteration, including removing or obliterating labels and opening or removing external
covers (unless authorized to do so by Zaxcom or an authorized Service Center), accident or mishandling while in the possession of
someone other than Zaxcom.

The Product was not sold to you as new.
Additional Limitations on Warranty
Zaxcom‟s warranty does not cover Product, which has been received improperly packaged, altered or physically abused.
