The Quantum Qflash TRIO QF8 combines a Qflash head with built-in FreeXwire
TTL radio and QTTL adapter for your digital camera. Slip it onto the camera
hot-shoe, connect a Turbo and go. TRIO's radio sends TTL commands to other
remote Qflash TRIO's. Configure distinct modes and settings of remote Qflash
TRIO's from the on-camera TRIO. And, the on-camera TRIO controls older Qflash
models mated to FreeXwire receivers. Control an unlimited number of remote
Radio QTTL signals from TRIO do not require line-of-site like camera optical
links. With a Qflash TRIO master flash on the camera hot shoe and Quantum TRIO's
or QFlash 5d-R's as remote flashes there is no need to worry about where to
mount a radio transmitter or receivers, worry about loss of battery power, or
whether a sync cord will fail at an inappropriate moment. Quantum's FreeXwire
radios are either built-in or directly attached to their Qflash. When your Turbo
powers up a Qflash, power is also supplied to the built-in or attached FreeXwire.
There is no other radio controlled flash system that can transmit wireless
camera TTL information to remote flashes up to 600 feet away.
