QUANTUM
RADIO SLAVE 4i
Radio Slave System for Remote Flashes and Motor Drives
Quantum’s Radio Slave 4i system allows you to
synchronize any number of remote flashes without
long sync cords, or use it to trip motor drives at
great distances. It uses digitally coded radio signals
that work indoors, outdoors, around corners and
through walls. This superior interference-free
operation permits many Radio Slaves to operate in
the same area. And, unlike other slaves, it cannot
be overpowered by the light of a flash.
The Radio Slave 4i system syncs up to 1/500 sec.
with focal plane shutters, 1/1000 with leaf shutters.
Faster than other wireless sync, Radio Slave 4i is
virtually indistinguishable from “wired” sync. And,
there is no waiting between triggers as with infra-
red slaves. When mounted on a camera with a hot shoe, the Sender (transmitter) unit connects directly without a cord. The
Remote (receiver) connects directly to the flash using the flash sync cord. Adapters are not needed. Confirmation of radio
signal is assured by Radio Slave’s status light. It also warns hours in advance of low battery. Each Radio Slave has 4 channels
of operation and is available in 4 discrete frequencies, to avoid interference from other shooters.
◆ Trigger any number of remote flashes
without a sync cord. Or you can trip a
motor drive camera, or a remote power
pack at great distances.
◆ Instant re-triggering for multiple flash
bursts. Faster than any motor drive
sequence.
◆ Range is up 350´ (110m), or 200´ (60m)
with the antenna down
◆ Hot shoe
mount for the
Sender allows
attachment to a
camera shoe,
and sync cord is
not required.
◆ Or use the supplied sync cord to connect
to camera sync. Can also be mounted to
brackets, dead shoes, etc. with velcro (sup-
plied).
◆ The 4i Remote operates up to 400 hours
on 4 AA batteries and 800 hours with 4 AA
lithium batteries. Also runs on AC power
with optional AC adapters.
