LECTROSONICS R1A IFB RECEIVER B21
Lectrosonics R1A Ifb Receiver B21
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 Lectrosonics IFB R1A Receiver provides simplicity and flexibility in a package that is intuitive for untrained users to operate.
The default frequency of the receiver is set by two rotary switches on the side panel. Up to five additional frequencies can also be programmed into the receiver 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.
A special button push sequence is required to set the receiver into the scanning mode to prevent accidental changes to the receiver memory. Simplified instructions are laser engraved into the housing of the receiver.
The receiver operates on a single 9 volt alkaline or lithium battery. Alkaline battery life is up to 8 hours. Lithium battery life is well over 20 hours. The LED indicator changes color from green, to yellow, to red as the battery voltage declines to provide plenty of warning before operation ceases.
An internal relay in the receiver will automatically detect a monaural plug connected to the output jack and switch accordingly. Full output power is available with either type of connector, without the power losses that result from a resistive circuit design. The antenna input is provided by the shield of the cable and headset or earphone connected to the output jack.
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 is housed in a rugged machined aluminum package. A spring- loaded belt clip is available as an accessory which provides a secure mounting on a wide variety of belts, pockets and fabrics.
The Lectrosoincs IFBR1A21 is tuned to Frequency Block 21 and comes with Australian Standard Compliance.
