The IFBR1a-VHF from Lectrosonics is a multi-frequency wireless beltpack IFB (Interruptible Fold Back) receiver that can be used for talent cueing and crew communication in broadcast and motion picture production. In addition, the IFB receiver provides simplicity and flexibility in a package that is intuitive for untrained users to operate.
Featuring two rotary-control switches on the side panel, the IFBR1a-VHF receiver can be programmed with up to five additional frequencies, and stored in the memory using the scan mode. If more than one frequency is stored in the receiver, the operator can scroll through all stored frequencies by simply pressing the volume knob.
Furthermore, it is built durable in a machined aluminum housing, and has a battery door that stays permanently attached when opened. It is powered by a single 9V alkaline battery, and will run for 8 hours, or up to 20 hours using a 9V lithium battery.
Finally, the receiver will drive a wide variety of earbuds, headphones and induction neck loops at substantial levels with loads from 16 to 600 ohms. An Allen wrench is included to adjust the frequencies manually, and a leather carrying case is also included.
