IFB Receiver
Introduction
Wireless IFB (interruptible fold back) systems are used for talent cueing and crew communications in broadcast and motion picture production. In other cases, the IFB system is used by directors and other management to monitor program audio during a production. The IFBR1C receiver provides simplicity and flexibility in a package that is intuitive for untrained users to operate. In spite of its tiny size, the new IFBR1C receiver offers excellent performance on par with all of Lectrosonics' IFB products.
The design uses +/-20 kHz FM deviation for efficient use of the bandwidth, with compandor noise reduction circuitry for an excellent signal to noise ratio. A supersonic Pilot Tone signal controls the audio output squelch to keep the receiver silent when no transmitter signal is received. The incoming RF signal is filtered and amplified, then mixed down to the IF frequency with a microprocessor controlled synthesizer.
If a monaural earpiece is connected, this condition is automatically accommodated, with no loss of audio output power or battery life. Full output power is available with either type of connector, without the power losses that result from a resistive circuit design. The headphone cable doubles as the receiving antenna.
The receiver will drive a wide variety of earbuds, headphones and induction neck loops at substantial levels, with loads from 16 Ohms to 600 Ohms.
The IFBR1C operates on two (2) double A batteries. The LED indicator changes color from green to red as the battery voltage declines to provide plenty of warning before operation ceases. Inside the battery door is a USB port for firmware updates in the field.
The IFBR1C is housed in a rugged, injection molded ABS package. A belt clip is included and provides a secure mounting on a wide variety of belts, pockets and fabrics.
Frequency Presets
There are 10 presets available for programming in the IFBR1C. The stored frequencies remain in memory during power OFF and even with the battery removed. Use the UP and DOWN arrows to scroll through the previously selected frequencies stored in the IFBR1C and quickly change frequencies for quick communication.
Simplicity
The unique design in this receiver is not only tiny, but provides simple one knob operation for on/off and audio level and easy on-the-fly programming with simple frequency adjustments and 10 preset slots available. Basic operation is simply a matter of rotating the knob to turn power on and adjust the volume level.
General Technical Description
Frequency Agility
The frequency agile IFBR1C Receiver is designed to operate with the Lectrosonics IFB transmitters and compatible Digital Hybrid transmitters. Microprocessor control of frequencies within each frequency block provides the ability to work around interference problems quickly and simply.

Press the PRESET button to access aditional setup items or turn the unit off to leave the setup menu.
Firmware Updates
Use the free IFBlue Updater to install firmware updates. The Updater (for both Windows and macOS), firmware update files and change notes are available from the IFBlue website:
www.IFBlue.com.
1) Open the battery door and connect the IFBR1C to your Windows or macOS computer with a USB cable. The cable must have a micro-B male connector to mate with the USB jack in the IFBlR1C.
2) Turn the IFBR1C on. Use the IFBlue Firmware Update Wizard to open the firmware file and install the new firmware version.
Initially, "Ir n" is shown, meaning failure is assumed until a test passes. The battery status LED will show red at this time, even if the battery is good, to indicate failure.
To start a test, hold the unit being tested up to the tester so that the IR windows face each other and are within a few inches apart. Press the UP arrow button on the

Troubleshooting
Symptom
LED NOT LIT
Possible Cause
· Battery not installed or depleted. · Power not turned on.
NO SOUND IN HEADPHONE
· AUDIO LEVEL turned all the way down. · Headphone plug not inserted fully. · Defective headphone or connector · Transmitter not operating. (See separate transmitter manual.) · Receiver not on the same frequency as the transmitter.
DISTORTED SOUND
· Transmitter gain (audio level) is far too high. Refer to the operating instructions section in the transmitter manual for details on gain adjustment.
· Receiver output may be mismatched with the headset or earphone. Adjust audio level on receiver to the correct level for the headset or earphone.
HISS AND NOISE, AUDIBLE DROPOUTS SHORT RANGE
· Transmitter gain far too low.
· Receiver antenna missing or obstructed. (Headphone cable is the antenna.)
· Transmitter antenna missing or obstructed.
· Operating range too great.
· Transmitter antenna obstructed. Move transmitter antenna and/or receiver to a position with a line of sight between the transmitter antenna and the receiver.
· Receiver antenna (headset cord) may need to be repositioned for a line of sight to transmitter antenna
· Receiver headphone cable is also the antenna. Make sure the cable is not coiled or wound up or wrapped around the receiver case.
DECIMAL POINT IS BLINKING ON FREQUENCY
· It is normal to see the decimal point blink briefly when making large changes to frequency, as when wrapping around the band edges.
· Can also mean the receiver is currently tuned to an invalid frequency.
· Otherwise, a blinking decimal point is a sign that something is wrong with the hardware.

Service and Repair
If your system malfunctions, you should attempt to correct or isolate the trouble before concluding that the equipment needs repair. Make sure you have followed the setup procedure and operating instructions. Check the interconnecting cables and then go through the Troubleshooting section in this manual.
We strongly recommend that you do not try to repair the equipment yourself and do not have the local repair shop attempt anything other than the simplest repair. If the repair is more complicated than a broken wire or loose connection, send the unit to the factory for repair and service. Don't attempt to adjust any controls inside the units. Once set at the factory, the various controls and trimmers do not drift with age or vibration and never require readjustment. There are no adjustments inside that will make a malfunctioning unit start working.
LECTROSONICS' Service Department is equipped and staffed to quickly repair your equipment. In warranty repairs are made at no charge in accordance with the terms of the warranty. Out-of-warranty repairs are charged at a modest flat rate plus parts and shipping. Since it takes almost as much time and effort to determine what is wrong as it does to make the repair, there is a charge for an exact quotation. We will be happy to quote approximate charges by phone for out-of-warranty repairs.
Returning Units for Repair
For timely service, please follow the steps below:
A. DO NOT return equipment to the factory for repair without first contacting us by e-mail or by phone. We need to know the nature of the problem, the model number and the serial number of the equipment. We also need a phone number where you can be reached 8 A.M. to 4 P.M. (U.S. Mountain Standard Time).
B. After receiving your request, we will issue you a return authorization number (R.A.). This number will help speed your repair through our receiving and repair departments. The return authorization number must be clearly shown on the outside of the shipping container.
C. Pack the equipment carefully and ship to us, shipping costs prepaid. If necessary, we can provide you with the proper packing materials. UPS is usually the best way to ship the units. Heavy units should be "double-boxed" for safe transport.
D. We also strongly recommend that you insure the equipment, since we cannot be responsible for loss of or damage to equipment that you ship. Of course, we insure the equipment when we ship it back to you.
