IFBlue IFBR1C Bodypack IFB Monitoring Receiver for Lectrosonics (A1: 470 to 537 MHz) 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 IFBlue IFBR1C BodypackReceiver for Lectrosonics 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.
Reliable, Professional Performance
The IFBR1C uses ±20 kHz FM deviation for efficient use of the bandwidth. The compandor noise-reduction circuitry delivers 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 using a microprocessor-controlled synthesizer.
The receiver's high-sensitivity design provides extended operating range both indoors and outdoors.
One-Knob Operation for Simplicity of Use
The IFBR1C provides simple, one-knob operation for on/off and audio level, and easy, on-the-fly programming with fast frequency adjustments. Basic operation is simply a matter of rotating the knob to turn power on and adjust the volume level.
On the side panel, membrane switches and a backlit LCD interface let you quickly select frequencies and save/recall presets.
10 Frequency Presets
There are 10 presets available for programming 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.
