Chapter 1
Introduction
The Zaxcom IFB100 is a 100 mW RF transmitter designed to be used with the Zaxcom TRX900 series
wireless microphones. The IFB100 uses a spread spectrum signal to send and receive IFB audio, timecode,
and remote control signals. By using spread spectrum techniques, the IFB is immune to interference.
In locations where multiple IFB100 units are used, you can set the Zaxcom TRX900 to a specific IFB100
unit.
What’s in the Box
The Zaxcom IFB100 contains the following items:
o IFB100 Transmitter
o Antenna
o Power Connector
o Manual on CD-ROM
Options
Zaxcom offers the following options:
Antennas
o 2.4 GHz 6 dB gain omni-directional
This antenna is recommended for indoor or studio use where it can placed in the center of the studio.
o 2.4 GHz 15 dB gain directional
This antenna is recommended when placed against a wall, or when a directional transmission is desired.
o 10 foot cable (~3 m) from IFB100 to 2.4 GHz antenna
Cable Selection
When selecting a cable to use between the IFB100 and the antenna, it should be as short as possible since
the IFB100 is using a 2.4 GHz signal. When using standard cabling, the recommended length should not
exceed 10 feet. However, a very low loss cable can be used if a cable longer than 10 feet is needed.
Permanent Installations
When permanently installing cables, use 1/2-in. Andrew heliax. Using heliax cabling, a run of 100 feet
(~ 30.5 metres) can be achieved without significant power loss.

Setting Up the IFB100
The IFB100 uses a series of menus to configure the unit. The following sections describe setting up the
IFB100 for the first time.
Power Requirements
The IFB100 requires an external 8 to 18 VDC power source. Ideally, the source should be 12 VDC, which
draws 125 mA current from a 12 VDC source. You need a power supply capable of supplying at least 1 amp
to operate the IFB100.
Audio Input
The two channel balanced audio input on the IFB100 uses a TA5 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.
Adjusting the Input Audio Level
The input audio is preset by Zaxcom at +4 dBu. However, this level can be adjusted. The following sections
describe how to adjust the input audio level depending on which model IFB100 you own.

Early units
o Remove the rear cover on the IFB100
o Adjust the input adjustment potentiometer located on the audio input connector board.
There is an adjustment potentiometer for each input channel shown below.
Trim pots

Currently Shipping Units
Currently shipping IFB100 units have the trim pots located on the outside of the unit. These are shown in
Figure 2.
Trim Pots
Figure 2 IFB100 Trim Pot Location (Current Units)
Time Code
Unless an external time code source is present, the IFB100 runs free time code. When connected to an
external time code source, the time code syncs with the external source.
Important: A stereo plug is required for external time code sync. The ring on the plug should be unconnected.
You cannot use a mono plug.

Configuration Menus
The Zaxcom IFB100 uses a series of menus for configuration. These menus are similar to other Zaxcom
wireless devices and behave the same way. To go from menu to menu, press the Menu button until the
appropriate menu appears.
There are two different sets of configuration menus. More commonly used features are placed in the
standard menu, features that do not have to be changed often are placed in the extended menu.

Main Menu
When you power on the IFB100, the main menu appears. This menu displays the following information:
o Transmitter frequency
o DC power indicator
o Audio level meter
o Status of the IFB100 transport remote control.
Starting and Stopping Recording
When in the main menu, pressing the increment or decrement keys generates a record or stop command
to all TRX900 units in the same group as the IFB100.
When setting the audio level, it should peak at -20 dB level.

TRX Transmitter Gain
The gain control function allows you to adjust the gain on the TRX900 series transmitters.
o Transmitter Gain Range: 0 to 38 dB
Setting the Transmitter Gain
1.
Set the Unit code on the IFB100 to match that of the TRX900 unit.
2.
Press the menu button until Gain appears on the LCD.
3.
Press the increment or decrement button to change the gain.
Note: If the TRX900 is not in range of the IFB or is on the fringe of coverage the gain control command may have to be
repeated.
Monitor the reception of the TRX900 unit being adjusted to verify the change to the gain setting. Each time
the gain setting is changed, the TRX900 changes its gain by 2 dB.
Remote Control
The Remote Control setting sets the group you control when you use any of the remote settings.
o Remote Control Range: All, or 0 to 200
You can set this to all or any of the unit numbers.
Setting the Remote Control Group
1.
Press the menu button until Remote Control appears.
2.
Press increment or decrement button to select the remote group’s ID code.
Remote Power Mode
The Remote Power Mode sets power mode each remote transmitter is set to.
o Remote Power Mode: On, Low1, Low2
On - Turns on all remote units.
Low1 - disables the RF Power Amplifier in remote units.
Low2 - disables the RF Power Amplifier and RF Board. In most cases you want to use Low2 if you are
using the remote power mode. When using the low2 mode, the TRX900 draws half the
current as the full power mode, saving you battery life.

Setting the Remote Power Mode
1.
Set the Unit code on the IFB100 to match that of the TRX900 unit.
2.
Press the menu button until Remote Powermode appears.
3.
Press increment or decrement button to enable (Low1 or Low2) or disable the power mode (on).
To verify the standby mode, monitor the reception of the TRX900 units. All TRX900 transmitters with the
same group code will be affected by the power command.
Time code menu
The time code generator on the IFB100 is in the free run mode unless it is connected to a time code
source.
Time Code Options: 23.98, 24, 25, 29.97 Non-Drop Frame (NDF), 29.97 Drop Frame (DF), 30 NDF,
30 DF
Setting the IFB Time Code
1.
Press the menu button until the Time Code generator menu appears.
The current generator time is displayed.
2.
Press increment or decrement button to change the time code rate to the appropriate frame rate.
If connected, the time code is in sync with the external code feeding the IFB100. If a TRX900 unit is in the
autoload mode, it goes into the record/stop mode when the time code is received by the IFB100.
IFB Frequency Selection
The IFB frequency menu is indicated on the LCD screen of the IFB100 by IFB FREQ.
o Frequency Range: 2.403 GHz to 2.475 GHz
The IFB100 can be adjusted in 1 MHz steps within the frequency range (2.4 GHz - 2.47 GHz) with a
minimum separation of 2 MHz between channels. However, it is recommended to use 8 MHz of channel
separation. This separation is recommended because of the Zaxcom TRX900 voting system.
If the TRX900 voting system is used, you need to use four adjacent 2 MHz channels to operate. For
example with the voting system, you would use 2.403 GHz, 2.405 GHz, 2.407 GHz, and 2.409 GHz. This
makes 2.411 GHz the next available free channel.
Using 2 MHz spacing the IFB100 support 36 IFB channels simultaneously.
To select the frequency
o Press the Menu button until the IFB FREQ menu appears.
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.

wireless devices are in the same area, since any device on the same group code as you can affect your
TRX900 unit. To avoid this, coordinate with others in the area and ensure everybody is on a separate
group code.
Once the group code is set, multiple TRX900 units can be controlled remotely.
Remote Control Unit Code
The Unit code allows you to set a unique identifier for a single TRX900 unit, and remotely control the unit.
