for selecting the Lectrosonics frequency agile, narrowband, T4 IFB (Interruptible Foldback) transmitter. The T4 is the result of over 100 years of engineering experience with the very latest components, in a design that addresses the most demanding professional applications. The Lectrosonics T4 IFB Transmitter along with the companion R1 or R1a IFB Receivers allow on-air talent to monitor program audio and receive cues from directors and other production personnel. The T4 IFB Transmitter is a rugged, machined aluminum package. The input section is adjustable for Rio Rancho, NM virtually any microphone or line level audio source. The antenna is a detachable, locking 1/4 wavelength flexible bronze cable that connects to a 50 Ohm BNC connector on the transmitter. Only the T4 IFB Transmitter is covered in this manual. Companion receivers are covered in separate manuals. The T4 IFB Transmitter will operate with any Lectrosonics R1 or R1a IFB Receiver in the same frequency group. The T4 is also compatable with the Lectrosonics 100 Series, 200 Series, and 400 Series receivers as well as several other brand systems. T4 General Technical Description The T4 IFB Transmitter is comprised of a number of functional subsystems, including Audio Input Interface, DSP Audio Processor and Pilot Tone, Frequency Synthesizer, Microcontroller, Transmitter, Antenna System and Power Supply. (See block diagram.) The T4 is designed to operate primarily with the Lectrosonics R1 and R1A IFB receivers, and is also capabable of operating with the Lectrosonics 100 Series, 200 Series, 400 Series receivers. The T4 features microprocessor control of 256 operating frequencies within any one of at least nine UHF frequency bands and the 944MHz band. The T4 uses 20 kHz deviation in the IFB and 100 series modes for an efficient use of bandwidth. The 200 Series and 400 Series modes use 75kHz bandwidth for high signal to noise ratio. The transmitter circuits are all regulated for frequency stability and high audio performance. The input amplifier is a discreet differential circuit which can be adjusted to allow the use of many different input sources with robust overload capability without clipping. Audio Input Interface The input sensitivity and XLR pin functions can be customized using a DIP switch located on the back panel. Different combinations of gain and input configurations are possible without rewiring the mic connector. Pin 1 of the XLR input connector is normally connected directly to ground but an internal jumper can be moved if a floating input is desired. The Audio (+) and (–) are “dry” inputs and can each withstand +/- 50 VDC. Audio DSP and Noise Reduction The original Lectrosonics IFB system was designed with single band compand ing which is an audio device that processes (compresses) the input signal so that the large dynamic ranges of the input signals can be transmitted to the receiver without overload or noise. A complementary system in the receiver recovers (decompresses) the original dynamics of the signal for full audio quality. Compression and expansion ratios are complementary at 2:1. High frequency pre-emphasis is implemented in the transmitter to provide another 10 dB signal to noise improvement. Matching de-emphasis is provided in all receivers. The IFBT4 is designed with Audio Digital Signal Processor algorithms that digitally emulate the original compandor circuits in order to maintain compatability with the IFBR1/IFBR1a, 100 Series, and 200 Series receivers using the same analog FM links. This same DSP circuitry also provides an algorithm compatible with the Lectosonics Digital Hybrid Wireless™ 400 Series systems and eliminates the need for pre-emphasis and de-emphasis. T4 IFB Transmitter Block Diagram LECTROSONICS, INC. Multi-Frequency IFB Transmitter Pilot Tone The T4/R1A system uses an ultrasonic tone modulation of the carrier to operate the receiver squelch. This “pilot tone” consists of a 29.997 kHz signal in the DSP and is mixed with the audio signal to the FM modulator. The pilot tone controls the audio output muting of the receiver and is filtered out of the audio signal immediately after the detector in the receiver so that it does not influence the compandor or various gain stages. The benefit of the pilot tone squelch system is that the receiver will remain muted until it receives the pilot tone from the matching transmitter, even if a strong RF signal is present on the carrier frequency of the system. The T4 DSP also generates pilot tones to operate with the 200 Series and 400 Series receivers as well as several other popular system receivers. Frequency Synthesizer The transmitter uses a synthesized, frequency selectable main oscillator. The frequency is extremely stable over a wide temperature range and over time. The push-button switches, located on the front panel of the unit, provides the user access to set 256 frequencies in 100 kHz steps over a 25.5 MHz range. This significantly alleviates carrier interference problems in mobile or traveling applications. Microcontroller Frequency adjustment and display are handled by the microprocessor. Nonvolatile memory is provided for holding the last frequency used, even if power is removed from the unit for any length of time. Each time the transmitter is powered up, it will display the last frequency used. Transmitter The T4 transmitter operates at 250 mW, more powerful than most IFB systems on the market today. The higher power ensures a clean signal free of dropouts and noise. The transmitter circuits are buffered and filtered for exceptional spectral purity. The extra clean signal that results reduces the chances for interference between multiple transmitter installations. Antenna System The antenna on the T4 consists of a flexible 1/4 wavelength bronze cable, detachable via a BNC connector. The 50 ohm output connector works conveniently with a variety of remote antennas for installation in studios and production trucks & vans. Power Delay There is a five second power-ON/OFF delay to prevent audio thumps when switching from XMIT to TUNE or from TUNE to OFF. This delay also gives the Frequency Synthesizer time to fully stabilize. When the transmitter is powered OFF, the Pilot Tone is first turned off muting the audio at the receiver before the rest of the transmitter is powered down. This prevents clicks, thumps or feedback from entering the sound system. Rio Rancho, NM T4 Front Panel Controls and Functions T4 Front Panel icon to indicate transmit (XMIT) mode. The MENU button is then used to navigate to the other function windows, see page..7? indicates the channel (or operating) frequency of the unit to the nearest 0.1 MHz (100 kHz). The LED display also indicates low input power by blinking continuously when the input voltage drops below 11.0 Volts. Select Buttons (Up and Down) OFF/TUNE/XMIT Switch OFF Turns the unit off. TUNE Mutes the transmitter RF output section while enabling all of the menus as well as the up and down select buttons for setting the operating frequency and all other functions of the transmitter. XMIT Normal operating position. With the switch the XMIT position, the unit is transmitting a modulated signal to the corresponding receiver except the ability to change frequency is locked out. The switch must be set to TUNE position in order to change the frequency. In XMIT position the buttons allow to display the transmitter HEX switch settings, the operating frequency and the TV channel and also allow the use of the menus to adjust the Audio Level and Rolloff . Power Up Sequence When the OFF/TUNE/XMIT switch is first turned on, the front panel LCD display cycles through the following sequences: 1. Displays Model and frequency block number: IFBT4 BLK 25 (example) 2. Displays installed firmware version number: VERSION 1.0 (example) 3. Displays the current compatibility mode setting: COMPAT IFB (example) 1. “TEST MODE” momentarily illuminating all display segments (8.8.8.8.) 2. Momentarily displays firmware version number, (i.e. 4.0) After stepping to a window using the MENU button the UP and DOWN and MENU buttons are used to further navigate to a selection choice. When the selection is made the choice is entered into the processor by pressing the MENU again. For example, from the MAIN window press the MENU button once to display the Audio Input level set window. Pressing the UP button increases the input gain and pressing the DOWN button decreases the input gain. Likewise, press the MENU button twice from the main window to display the Frequency window. The transmitter frequency is then changed by pressing the UP or DOWN button. Each push will change the frequency, up or down, in 100 kHz increments, or one channel at a time. The FREQ buttons are enabled when the OFF/TUNE/XMIT switch is in the TUNE position. The frequency can be stepped a single frequency channel at a time by a momentary push or if a selected FREQ button is pressed for more than two seconds, the speed of change increases to about five channels per second. Also, large increment steps can be made by holding in the MENU button while momentarily pressing the UP or DOWN button. The T4 will “remember” the last channel selected when the unit is turned off, and it will set itself to that frequency when the unit is reenergized. When the switch is in the XMIT mode, pressing the FREQ up/down buttons will not disturb the frequency or the transmitter signal output. Note: When the highest or lowest frequency is reached, the unit will wrap around and continue in the same direction at the other end of the range. Rolloff The low frequency rolloff is normally 3dB down at 35 Hz. The rolloff can be changed to 50 Hz by navigating to the ROLLOFF window and using the UP or DOWN button to select the desired rolloff. Pressing MENU then enters the setting into the processor. 3. Displays operating frequency in MHz. LCD Display The LCD is a backlit graphic type liquid crystal display that is used to monitor the unit operation and to configure the IFBT4 for desired settings. Upon initial power up, the display defaults to the MAIN window that displays an active audio VU meter and an icon in the shape of a “T” to indicate TUNE mode or an antenna Audio Level Control The Audio Level Control is used to adjust the audio input level for proper modulation. The gain range is +24dB to -18dB. The reference for this control can be changed with the rear panel MODE switches. See the INSTALLATION AND OPERATION section for more information on the MODE switches. LECTROSONICS, INC. Multi-Frequency IFB Transmitter T4 Menu Diagram Rio Rancho, NM T4 Rear Panel Controls and Functions T4 Rear Panel 12 VDC (Power Input Connector) The T4 is designed to be used with the CH20 external (or equivalent) power source, which is plugged into the 6-18 VDC external power input connector. The nominal voltage to operate the unit is 12 VDC; although it will operate at voltages as low as 6 VDC and as high as 18 VDC. A suitable alternate power source must be able to handle 200 mA continuous consumption. Antenna XLR Jack A standard XLR female jack accepts a variety of input sources depending on the setting of the MODE dip switch. XLR pin functions can be changed to suit the source depending on the positions of the individual switches. For detailed information on the setting of these switches see the INSTALLATION AND OPERATION section. The T4’s ANTENNA connector is a standard 50 ohm BNC configuration, which can accept an integral whip or a cable to a remote antenna. Mode Switches Name Switch Positions 1 2 3 4 CC TTTS MIC Balanced Input Sensitivity 3 = Audio 1 = Common No -10 dBu SSST 2 = Hi 3 = Lo 1 = Common Yes -42 dBu LINE SSTT 2 = Hi 3 = Lo 1 = Common Yes 0 dBu RTS1 STTT 2 = Hi 1 = Common No 0 dBu RTS2 TTTT 3 = Hi 1 = Common No 0 dBu XLR Pins These dip switches configure the XLR input jack to accommodate a variety of audio sources. The rear panel is marked with the most common switch combinations. The MODE switches allow the T4 to accommodate a variety of input sources by changing the input sensitivity and the pin functions of the input XLR jack. Marked on the rear panel are the most common settings. Each setting is detailed below. Switches 1 and 2 adjust the XLR pin functions while switches 3 and 4 adjust the input sensitivity. (mode switch chart here) LECTROSONICS, INC. Multi-Frequency IFB Transmitter Installation and Operation 1) The T4 transmitter is shipped with pin 1 of the XLR input connector tied directly to ground. If a floating input is desired, a Ground Lift Jumper is provided. This jumper is located inside the unit on the PC board near the rear panel XLR jack. If a floating connection is desired, open the unit and move the Ground Lift Jumper to the desired location. 5) Attach the antenna (or antenna cable) to the BNC connector on the rear panel. Location of Ground Lift Jumper: 9) Position the microphone. The microphone should be placed in the position in which it will be used during the program. 6) Mute the sound source connected to the T4. 7) Set the OFF/TUNE/XMIT switch to TUNE. 8) Step MENU to the frequency/channel window and adjust the transmitter to the desired frequency with the front panel FREQ up/down buttons. 10) Step the MENU button to the LEVEL window. While speaking at the same voice level that will be used during the program, observe the display audio meter. Using the DOWN button, set the AUDIO LEVEL gain to a low level, -10 or -18 so that the audio peaks are well below 0dB limiting on the scale. Then gradually adjust the AUDIO LEVEL gain with the UP button until the audio meter occasionally peaks at the maximum of 0dB on the scale“. -There is over 15 dB of limiting range without overload above the “0” indication. It is desirable that the audio peaks at or slightly above 0dB about 5-10 percent of the time during use. 2) Set the MODE switches on the rear panel to match the specific input source to be used. (See Mode Switches.) 3) Insert the power supply plug into the 6-18 VDC jack on the rear panel. 4) Insert the microphone XLR plug into the input jack. Ensure the pins are aligned and that the connector locks in. Rio Rancho, NM 11) Once the transmitter audio gain has been set, the receiver and other components of the system can be energized and their audio levels adjusted. Set the power switch on the T4 transmitter to the XMIT and adjust the associated receiver and sound system level as required. Note: There will be a delay between the moment the transmitter is energized and when audio will actually appear at the receiver output. This intentional delay eliminates turn on thumps, and is controlled by the pilot tone squelch control. T4 Operating Notes The AUDIO LEVEL control should not be used to control the volume of the associated receiver. This gain adjustment is used to match the T4 input level to the incoming signal from the sound source to provide full modulation and maximum dynamic range. If the audio level is too high — the audio metering will exceed the 0dB level too frequently. This condition may reduce the dynamic range of the audio signal. If the audio level is too low — the audio metering will be too far below the 0dB level. This condition may cause hiss and noise in the audio, or pumping and breathing in the background noise. Accessories CH20 The input limiter will handle peaks over 15 dB above full modulation, regardless of the gain control setting. The limiter uses a true absolute value circuit to detect both positive and negative peaks. The attack time is 5 milliseconds and the release time is 200 milliseconds. Occasional limiting is desirable, indicating that the gain is correctly set and the transmitter is fully modulated for optimum signal to noise ratio. Different voices will usually require different settings of the AUDIO LEVEL control, so check this adjustment as each new person uses the system. If several different people will be using the transmitter and there is not time to make the adjustment for each individual, adjust it for the loudest voice.

Rio Rancho, NM 11 T4 Frequency Blocks and Ranges The table below lists the factory designated frequency ranges available for the T4 IFB Transmitter. Each T4 transmitter is built to cover a pre-selected range of frequencies (a “block”) as shown below. The transmitter will tune to any of 256 different frequencies within this factory assigned block. The block number is determined by this formula: 25.6 × Freq. (MHz) = Lowest freq. (MHz) in the block To determine a block number from a frequency: Freq. (MHz) divided by 25.6 = Block number It is handy to remember these formulas, in case you do not have a copy of the table. For example, suppose you need to know which block covers 685.500 MHz, which is in the middle of the Block 26 frequency range. 685.500 divided by 25.6 = 26.77734375 The first two digits left of the decimal are the block number. In this case, 685.500 MHz falls within block 26. Block 944 is an exception to this block numbering system and depicts the actual frequency of the block since it is only a 6MHz band with 78 frequency channels. The T4 IFB transmitter antennas are color coded to indicate the frequency block that they operate within. The length of the antenna varies with the frequency block. The actual length of the antenna is not as critical as it might appear in the table below. The usable bandwidth of the detachable antenna is +/- 50 MHz from the block’s center frequency, so it is acceptable to use an antenna from an adjacent block above or below the operating frequency if some loss in range can be tolerated. Part of block 23 is not used since it covers a 608 to 614 MHz band that is illegal for use with wireless microphones.
