Nevertheless, operating this microphone system without a license is subject to certain restrictions: the system may not cause harmful interference; it must operate at a low power level (not in excess of 50 milliwatts); and it has no protection from interference received from any other device. Purchasers should also be aware that the FCC is currently evaluating use of wireless microphone systems, and these rules are subject to change. For more information, call the FCC at 1-888- CALL-FCC (TTY: 1-888-TELL-FCC) or visit the FCC’s wireless microphone website at www.fcc.gov/cgb/wirelessmicrophones. To operate wireless microphone systems at power greater than 50mW, you must qualify as a Part 74 user and be licensed. If you qualify and wish to apply for a license go to: http://www.fcc.gov/Forms/Form601/601.html Rio Rancho, NM IFBT4-VHF General Technical Description Introduction Audio Input Interface This version of the IFB “base station” transmitter operates in the television broadcast band from 174 to 216 MHz (US TV channels 7 through 13). It will tune across the entire band, so clear frequencies can be found almost anywhere. The standard 3 pin XLR connector on the rear panel handles all audio inputs. The four DIP switches allow setting the input sensitivity for low levels, such as microphone inputs, or for high level line inputs, balanced or unbalanced. The switches also offer special settings to provide the proper input configurations to match to Clear Com, RTS1, and RTS2 intercom systems. Pin 1 of the XLR input connector is normally connected to ground but an internal jumper can be moved if a floating input is desired. Phantom supplied microphones may be connected without the need for DC isolation at the input of the transmitter. The VHF spectrum has not been impacted by the spectrum auctions and re-packing as much as the UHF spectrum, so the idea behind this product design is to operate an IFB system in the VHF band and free up space for wireless microphones in the UHF band. The IFBT4 features a graphics type backlit LCD display with a menu system similar to those provided on other Lectrosonics receivers. The interface can be Locked to prevent a user from changing any settings but still allow browsing of the current settings. A user-selectable low frequency roll-off can be set for 35 Hz or 50 Hz as needed to suppress low frequency acoustic noise or to extend the frequency response. DSP-controlled Input Limiter The unit can be powered from any external DC source of 6 to 18 Volts at 200 mA or from the provided 12 Volt power supply with a locking power connector. The power inlet has an internal self-resetting fuse and reverse polarity protection. The transmitter employs a digitally-controlled analog audio limiter prior to the analog-to-digital converter. The limiter has a range greater than 30 dB for excellent overload protection. A dual release envelope makes the limiter acoustically transparent while maintaining low distortion. It can be thought of as two limiters in series, connected as a fast attack and release limiter followed by a slow attack and release limiter. The limiter recovers quickly from brief transients, so that its action is hidden from the listener, but recovers slowly from sustained high levels to keep audio distortion low and preserve short term dynamic changes in the audio. The housing is contructed of machined aluminum extrusion with a durable electrostatic powder coating. The front and rear panels are machined aluminum with an anodized finish and laser etched engraving. The included antenna is a right angle, ¼ wavelength whip with a BNC connector.

Synthesized VHF IFB Transmitter Digital Hybrid Wireless® Technology The design is based upon the patented Lectrosonics Digital Hybrid Wireless® system.* While at the time of the first release of the product, there is only a companion analog receiver, the Digital Hybrid Wireless system is included for compatibility with future products. Audio Signal Processing Lectrosonics IFB systems use a single band compandor and pre-emphasis/de-emphasis to reduce noise. This signal processing is generated and applied by the DSP for accuracy and clean handling of signal dynamics. The DSP also provides the ability to employ compatibility modes for use with other wireless equipment in the VHF spectrum that may come along in the future. Pilot Tone Squelch System Lectrosonics IFB systems use a supersonic “pilot tone” to control the squelch activity in the receiver. A valid RF signal will include the pilot to signal the audio output to open. Even strong interference on the same frequency cannot open the audio output if the pilot tone is not present. During normal operation, an IFB receiver will listen for the distinctive pilot tone, remaining silent (squelched) until the pilot tone is detected. The pilot tone is located well above audio frequencies and is never passed through to the receiver’s audio output. Power Delay When powering the transmitter on and off, and when switching between the XMIT and TUNE modes, intelligent circuitry adds brief delays in order to allow time for circuits to stabilize, both locally and in the matching receiver. These delays prevent clicks, thumps and other noise in the audio. Microcontroller The microcontroller oversees most system operations, including RF frequency and output, DSP audio functions, buttons and display, and more. User settings are stored in non-volatile memory, so they are retained even when the power is turned off. Transmitter The transmitter operates at the maximum allowed RF power level to ensure a clean signal free of dropouts and noise. All transmitter circuits are buffered and filtered for excellent spectral purity. The clean transmitted signal reduces the chances for interference in multiple transmitter installations. Antenna Port The 50 Ohm BNC output connector will work with standard coaxial cabling and remote antennas. Frequency Agility The IFBT4 transmitter uses a synthesized, frequency selectable main oscillator. The frequency is extremely stable over a wide temperature range and over time. The transmitter’s standard tuning range covers 239 frequencies from 174 to 216 MHz in 175 kHz steps. to alleviate interference problems in mobile applications. Rio Rancho, NM IFBT4-VHF Front Panel Controls and Functions IFBT4 Front Panel the Main window navigates to the Frequency window. The Frequency window displays the current operating frequency in MHz, as well as the standard Lectrosonics hex code. Also displayed is the UHF television channel to which the selected frequency belongs. In XMIT mode, it is not possible to change the operating frequency. In TUNE mode, the Up and Down buttons may be used to select a new frequency. OFF/TUNE/XMIT Switch OFF Turns the unit off. TUNE Allows all functions of the transmitter to be set up, without transmitting. The operating frequency may only be selected in this mode. XMIT Normal operating position. The operating frequency may not be changed in this mode, though other settings may be changed, so long as the unit isn’t “Locked.” Power Up Sequence When power is first turned on, the front panel LCD display steps through the following sequence. 1. Displays Model and the firmware verson (e.g. IFBT4VHF and V1.0). 2. Displays the current compatibility mode setting (e.g. COMPAT IFB). 3. Displays the Main Window. Main Window The Main window is dominated by an audio level meter, which displays the current audio modulation level in real time. In TUNE mode, a blinking capital “T” is displayed in the lower left corner to remind the user that the unit is not yet transmitting. In XMIT mode, the blinking “T” is replaced by an antenna icon. Audio limiting is indicated when the audio bargraph extends all the way to the right and widens somewhat. Clipping is indicated when the zero in the lower right corner changes to a capital “C”. The Up and Down buttons are disabled in this Window. Frequency Window Pressing the MENU button once from The UP and DOWN buttons navigate in 175 kHz increments. Holding the MENU butto+Up and MENU+Down move 2.8 MHz at a time. In any of the various group tuning modes, the currently selected group identifier is displayed to the left of the hex code, and the Up and Down buttons navigate among the frequencies in the group. In factory group tuning modes A thru D, MENU+Up and MENU+Down jump to the highest and lowest frequencies in the group. In user group tuning modes U and V, MENU+Up and MENU+Down permit access to frequencies not currently in the group. Pressing and holding the Up or Down button invokes an autorepeat function, for faster tuning. Audio Input Gain Window Pressing the MENU button once from the Frequency window navigates to the Audio Input Gain window. This window greatly resembles the Main window, with the exception that the current audio input gain setting is displayed in the upper left corner. The Up and Down buttons may be used to alter the setting while reading the realtime audio meter to determine what setting works best. The gain range is -18 dB to +24 dB with 0 dB nominal center. 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. Setup Window Pressing the MENU button once from the Audio Input Gain window navigates to the Setup window. This window provides access to a menu for various setup screens. Initially the active menu item is EXIT. Pressing the Up and Down keys permits navigation to the menu items: COMPAT and ROLLOFF. Pressing the MENU button selects the current menu item. Selecting EXIT navigates back to the Main window. Selecting any other item navigates to the associated setup screen. ROLLOFF Setup Screen The ROLLOFF setup screen controls the low frequency audio response of the IFBT4 by moving the 3 dB corner LECTROSONICS, INC. Synthesized VHF IFB Transmitter of a 4 pole lowpass digital filter.

Rio Rancho, NM IFBT4-VHF Rear Panel Controls and Functions IFBT4 Rear Panel Input Configuration (Mode Switches) The MODE switches allow the IFBT4 to accommodate a variety of input source levels 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. Name XLR Jack A standard XLR female jack accepts a variety of input sources depending on the setting of the rear panel MODE switches. 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. Power Input Connector The IFBT4 is designed to be used with the CH20 external (or equivalent) power source. 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. External power sources must be able to supply 200 mA continuously.

LECTROSONICS, INC. Synthesized VHF IFB Transmitter Frequency Selection The R1A-VHF receiver provides two 16-position rotary switches to select the frequency, adjusted with a small screwdriver inserted in the slot in the middle of the switches. The left-hand switch makes 2.8 MHz steps and the right-hand switch in 175 kHz steps, with the switch positions marked in hexadecimal numerals 0 through F. Frequencies are designated by two characters, such as B5, where first character is the left-and switch position and the second character the right-hand switch position. Thus, in this example, B5 would indicate 205.775 MHz, as shown in the table below. The front panel LCD on the IFBT4-VHF transmitter displays frequency in MHz and in the two character hexadecimal method.

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. For floating input, open the unit and move the Ground Lift Jumper to the outermost contacts. Location of Ground Lift Jumper: 10) Once the transmitter audio gain has been set, the receiver and other components of the system can be turned on and their audio levels adjusted. Set the power switch on the IFBT4 transmitter to 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 the actual appearance of audio at the receiver output. This intentional delay eliminates turn-on thumps, and is controlled by the pilot tone squelch system. Adjust Audio Input Level The AUDIO LEVEL control adjusts the gain applied to the incoming audio signal. This gain adjustment is used to match the input level to the incoming signal from the sound source to provide full modulation and the maximum signal to noise ratio, not to set the volume of the associated receiver. Jumper placed toward PCB as shown connects pin 1 to ground. Move jumper to outside contacts to lift ground. If the audio level is too high, compression or distortion may occur. The audio level meter will reach the 0 dB level (full scale) frequently or remain indicating full scale. Input limiting begins when a vertical line appears at the right end of the level indicator. Input limiting indicator 2) Set the MODE switches on the rear panel to match the specific input source to be used. See Inpout Configuration (Mode Switches). 3) Insert the power supply plug into the 6-18 VDC jack on the rear panel. 4) Insert the microphone or other audio source XLR plug into the input jack. Ensure that the pins are aligned and that the connector locks into place. 5) Attach the antenna (or antenna cable) to the BNC connector on the rear panel. 6) Set the OFF/TUNE/XMIT switch to TUNE. 7) Press the MENU button to display the Frequency Window and adjust the transmitter to the desired frequency with the front panel Up and Down buttons. 8) Position the microphone. The microphone should be placed where it will be located during actual use. If the audio level is too low, the audio level meter will continuously indicate a low level. This condition may cause hiss and noise in the audio, or pumping and breathing in the background noise. Low input level The input limiter will handle peaks up to 30 dB above full modulation, regardless of the gain control setting. Occasional limiting is often deemed 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 audio input gain settings, 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 9) Use the MENU button to navigate to the Audio Input Gain Window. While speaking at the same voice level that will be present during actual use, observe the audio meter display. Use the Up and Down buttons to adjust the audio input gain so that the meter reads close to 0 dB, but only rarely exceeds 0 dB (limiting). 10 LECTROSONICS, INC.
