IFBlue IFBR1C Belt-Pack IFB Receiver
The IFBlue IFBR1C is a belt-pack IFB receiver that gives talent, directors, producers, and crew a simple way to hear cues and monitor the location sound mix. It works with the Lectrosonics IFBT4 and IFBT4-VHF, and with any Digital Hybrid Wireless transmitter in IFB compatibility mode.
The IFBR1C is built to be easy for untrained users, with a single top knob for power and level, an LCD for frequency selection, and 10 presets for storing frequencies. It uses ±20 kHz FM deviation and compandor noise reduction, and an ultrasonic pilot tone keeps the output silent when no transmitter signal is present.
The headphone cable doubles as the antenna. The receiver drives earbuds, headphones, and induction neck loops with loads from 16 to 600 ohms, and a mono earpiece works with no loss of output power or battery life.
Two AA batteries run it for more than 10 hours on alkaline, 12 on NiMH, and 20 on lithium, and the LED changes from green to red as the voltage falls. The supplied NiMH cells charge in the receiver on the IFBlue CHSIFBR1C charging station. A USB port inside the battery door handles firmware updates, and the housing is injection-molded ABS with an attached belt clip.
You are responsible for selecting the approved frequencies for the region where the transmitter is operating.
