IFBlue Receiver Kit with Charging Dock (Freq. Band A1: 470.100 - 537.575)

About: IFBlue Receiver Kit with Charging Dock (Freq. Band A1: 470.100 - 537.575)

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. The design uses +/-20 kHz FM deviation for efficient use of the bandwidth, with a compander noise reduction circuitry for an excellent signal to noise ratio. A ultrasonic Pilot Tone signal controls the audio output squelch to keep the receiver silent when no transmitter signal is being 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 audio 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.

Full audio 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 receiver operates on AA batteries that will provide more than 12 hours of operation. 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 durable, injection molded package. An attached belt clip is included and provides a secure mounting on a wide variety of belts, pockets and fabrics.

FBR1C functions with two (2) AA batteries; 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-re- chargable) or “NiMH” (rechargeable) via the slide switch next to the USB connector. Press the battery door closed until you hear the retaining clasps snap.

Receiver Battery Charging Station

This battery charging station provides a convenient and organized means of recharging 4 IFBlue receivers at once.

The CHSIFBR1C charging station features an individual LED on each charging module. When a IFBR1C is being charged, the LED next to it will glow GREEN. When the battery is fully charged, the LED will be OFF. If a fault oc- curs, the power to the slot will be disabled and the LED will BLINK GREEN. A timer keeps track of the charging activity and turns the LED off if the battery cannot be charged after a period of approximately 2.5 hours.

Each charging module is reverse polarity protected and individually fused (10A one-time fuse).

• Each module charges up to 4 IFBR1C receivers (with rechargeable NiMH batteries)
• Connect multiple CHSIFBR1Cs mechanically for convenience
• Individual charging circuits and status indicators
