RadioPopper JR2 overview

  • 1Description

RadioPopper has put together this JR2 Studio Kit for Einstein with 1 Receiver to give photographers the benefit of wireless triggering and power control at distances from 300-1750' away. The kit includes 1 JR2 Transmitter and 1 Receiver.


The RadioPopper Jr2 Transmitter is a 16-channel, 4-group radio transmitter that operates on the 902-928 MHz ISM band and is capable of adjusting the output of the flash using the kit's Jr2 receiver for Einstein 640 flash units. Triggering and power control from distances of 300-1750' depending on conditions and environment is possible.

The transmitter's simplified, intuitive backlit display works on an easy to use button and dial design that indicates power levels, group selection, radio channel selection local or remote control, and remaining battery power. The transmitter gets 20 hours of run time on 2 AAA batteries and weighs 1.7 oz. Triggering at sync speeds up to 1/500 sec is possible with cameras that have leaf shutters. The Jr2 Transmitter will also trigger a wide variety of RadioPopper receivers besides the JR2 receiver but without power control.


This RadioPopper Radio Receiver for Einstein 640 Flash Head plugs into the body of the Paul C. Buff Einstein 640 allowing triggering of the flash from distances up to 1750'. The receiver works with virtually all RadioPopper systems and requires the kit's Jr2, or optional PX, JrX, or Nano transmitters for use. In addition to remote triggering, the Jr2 Transmitter is also capable of controlling the Einstein's power levels. Since the receiver draws its power from the flash head, no batteries are needed.
