EZset Operation
EZset Studio
– EZset Studio enables the ability to adjust the power levels of Alien Bees, White Lightning and Zeus
brand lights from a JrX (or PX) Transmitter. After setting the appropriate option switches (see option switches section),
the three dials on the side of a JrX transmitter can control the output power of up to three groups of lights. Note that
turning the dial of the JrX transmitter is directly proportional to adjusting the power slider on the back of the light. For
example, a half turn of the dial is the same as putting the light’s slider half-way to full.
To properly set up the EZset Studio system with a JrX Receiver, please follow the correct installation procedure.
1. Ensure that the JrX Receiver and the studio light are both turned OFF.
2. Attach the JrX Receiver to the studio light with the supplied “telephone” data cable.
3. Disable the optical slave function of the light by inserting the supplied 3.5mm plug into the light’s sync port.
4. Power on the studio light.
5. Power on the JrX Receiver. JrX Receiver must be powered on after the studio light to enable proper tracking.
6. When the JrX Receiver is turned on, the modeling lamp should quickly ramp up then down and then trigger once.
EZset Strobe – EZset Strobe enables the ability to adjust the power levels of TTL / “Dedicated” flashes compatible with
Canon or Nikon Cameras. The RPcube Canon is required for Canon compatible strobes and the RPcube Nikon is required
for Nikon compatible strobes. Use the supplied 3.5mm stereo cable to connect the sync connector of the JrX Receiver
to the matching 3.5mm jack provided on the RPcube.
After setting the appropriate option switches (see option switches section), the three dials on the side of a JrX
transmitter can control the output power of up to three groups of strobes. Note that EZset Strobe can control roughly 8
stops of flash power. Each 1/8th turn of the dial on the JrX Transmitter will represent 1 stop of flash power. Note that
due to the wide variety of flashes available, each 1/8th turn may be slightly greater or slightly less than 1 stop of flash
power.
The EZset Strobe function has been approximately calibrated for stop accurate light output from a Nikon SB-800 Speed
Light. Though smaller or larger strobes may put out more or less power, a 1/8 turn of the dial will still roughly equal
one stop of power adjustment regardless of the make, model, or size of strobe used.
NOTE: It is possible to mix both EZset Studio and EZset Strobe functionality within the same lighting system. For
example, placing studio strobes (EZset Studio) on one group and placing hand held strobes (EZset Strobe) on
another group. It is also possible to mix the above functionality with proper ETTL/iTTL functionality when used with
a RadioPopper PX Transmitter. The ETTL/iTTL pre-flash and calculations are all performed before activating lights
attached to JrX Receiver units, thus the lights attached to JrX Receiver units will not alter the ETTL/iTTL exposure. All
ETTL/iTTL groups, ratios, and power levels are maintained.
