Lectrosonics R1a IFB Receiver
The frequency agile IFB R1a FM Receiver is designed to operate with the Lectrosonics IFB T1 Transmitter and features microprocessor control of 256 frequencies of
operation within each frequency block. Any one of nine different frequency blocks are factory available.
The unique microcontroller design in this receiver provides simple one knob and one LED operation for audio level, switching frequencies (channels), and easy
on-the-fly programming. The receiver frequency can be set by manually using the two rotary HEX switches on the side of the unit or by using the automatic scan and
store function, or both.
When powered ON, the receiver will default to the frequency set by the switches. A nonvolatile memory can store up to five additional frequencies accessible by pressing the knob. The memory remains during power OFF and even with the battery removed.
