IFBlue IFBR1C - Compact Wireless IFB Bodypack Receiver (Block A1 / 470-538 MHz)

The IFBlue receiver provides simplicity and flexibility in a tough package that is intuitive for untrained users to operate. In spite of its small size, the receiver pack offers excellent performance and convenience. The dock charging feature and supplied rechargeable batteries make daily use a snap, while 10 programmable preset frequencies give you excellent flexibility on set or in the studio.

The IFBlue receiver pack is offered in five different frequency ranges to match existing T4 transmitters: VHF (174-216 MHz), A1 (470-537 MHz), B1 (537-614 MHz), C1 (614-692 MHz) and 941 (941-960 MHz).Transmitters available from Lectrosonics include the IFBT4, IFBT4-VHF, or any Digital Hybrid Wireless transmitter in IFB compatibility mode.

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 compandor 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.

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.
