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.

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.

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.

IFBR1C Features

On/Off and Volume Knob
Turns unit on or off and controls headphone audio level. When the IFBR1C is first turned on, the firmware version will display briefly.

Battery Status LED
When the battery status LED glows green, the batteries are good. The color changes to red at a midpoint during the runtime. When the LED begins to blink red, only a few minutes remain.

The exact point at which the LED turns red will vary with battery brand and condition, temperature and power consumption. The LED is intended to simply catch your attention, not to be an exact indicator of remaining time.

NOTE: The LCD will also alert when the battery is critically low.

RF Link LED
When a valid RF signal from a transmitter is received,
this LED will light up blue.

Headphone Output
A 3.5 mm mini phone jack accommodates a standard mono or stereo type 3.5 mm plug. The unit will drive low or high impedance earphones. The jack is also the receiver antenna input with the earphone cord acting as the antenna. The cord length is not critical but must be at least 6 inches minimum.

USB Port
Firmware updates via the IFBlue Updater are made easy with the USB port in the battery compartment.

Installing the Batteries

IFBR1C functions with two (2) AA batteries (+1.5 VDC each); alkaline, lithium, or NiMH rechargeables (supplied).

Pinch the buttons on each side of the battery door, and pull the door toward you to open. Install the batteries according to the polarity diagram. Select either “primary” (non-rechargable) or “NiMH” (rechargeable) via the slide switch next to the USB connector. Press the battery door closed until you hear the retaining clasps snap.

WARNING! Do NOT select (NiMH) rechargeable if you are using Lithium or Alkaline batteries; these are primary cells and can be damaged by enabling recharging. Use the NiMH only with rechargeable Nickel Metal Hydride NiMH) batteries.

Battery Setup
Use the arrows to select A for alkaline, L for lithium. The default is alkaline.

Troubleshooting

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.
