The TR-611 for Canon and TR-612 for Nikon appear to likely provide a HSS function when used with respective TTL and HSS enabled speedlites.
Though likely of more interest for many Flashpoint RoveLight / Jinbei HD600 II, HSS portable studio light owners, is the possibility of the TR-611 / 612 providing a badly needed alternative transmitter unit for these otherwise great lights.
UPDATE – January 1st 2015 – Jinbei have contacted us to say the TR-611 and TR-612 will NOT be produced.
The good news is that Jinbei cancelled the production because they are making major changes / upgrades to the trigger, and the new trigger should be available in the 1st half of 2015.
UPDATE – March 12 2015 – Jinbei have provided an image of an engineering sample of the coming TR-A6 transmitter, which at this time is expected to be available around mid year 2015.
If you look closely the TR-611 / 612 also provide UP and DOWN remote power adjustment buttons, as well as a remote modeling light button, which very much appear to correspond with the RoveLight / HD600 II (and current TRS transmitter). As well as providing the HSS signal needed for HSS use with these strobes.
What is also interesting about the TR-611 / 612 is that they now provide 3 groups: A / B / C.
The only problem here still is that the current RoveLight / HD600 II do not currently support any groups.
For those that may not be familiar with the RoveLight / HD600 II, the current 2.4GHz TRS radio transmitter used with these lights provides a basic method of remote power control via simple UP and DOWN power level buttons.
There is no group control on the strobes or TRS transmitter though. So this power adjustment works fine for just one strobe, though adjusting a number of strobes individually generally means using a number of transmitter units set to different channels (one transmitter for each light), and another just to fire all of the lights.
The coming TR-611 / 612 provide 3 groups, though the problem still remains that the current RoveLight / HD600 II do not currently support any groups.
There is still some hope that these groups may actually be able to function with the RoveLight / HD600 II though. Because Jinbei actually appear to have fudged together a method of using channels as a type of group control on another of their transmitter units previously.
Setting a certain channel on a strobe would link to a certain group on the transmitter unit. This could provide an individual group control for the remote power adjustment, and the transmitter could then be set to fire all channels (so it can still fire all of the strobes).
The example below uses ID:3, which would be like Group C.
We don’t know if this Group / Channel interaction will actually be enabled in the coming TR-611 / 612 transmitter or not (as its hard to get any information from Jinbei at all).
Though Jinbei do have a LOT of current mains powered studio strobe models which also use the current TRS transmitter for remote power control, and do not have any group support either.
So it would greatly improve the usability of all of these strobes if Jinbei did provide a new transmitter which makes the most of channels as a group function for now, and hopefully they will do that.
Without any LCD screen indicating power levels, the TR-611 / 612 may not be the transmitter unit many RoveLight owners were hoping for (though any improvement on the TRS would certainly be welcomed).
We really don’t know if Jinbei may possibly still have another more sophisticated transmitter in the works as well though (as a Jinbei have at least asked about a suitable transmitter unit previously).
Sorry we do not have much information on a new TRS transmitter at this stage otherwise. A number of RoveLight owners have been eagerly after any information possible though, and the TR-611 / 612 certainly do appear to have a connection, as Jinbei do intend to have their own HSS enabled transmitter units for the RovelLight / HD600 II eventually.
PRICE AND AVAILABILITY
The Jinbei TR-611 and TR-612 price and availability are currently unknown (they were listed in a 2014 Jinbei catalog).
