Function Overview

Y
our QUADX 3000 is a versatile and powerful photographic generator
.
Flash Power
The pack has four head sockets which can deliver a total power of 3000Ws in various ways.
At all
times, the pack will indicate the available power at any socket.
This is scaled such that 3000Ws is
represented as 10 on the display
. Lower power levels are proportional and adjustable in steps of 0.1
stops. e.g.
A
value of 9.0 represents half the power
, 1500Ws.
The pack is divided into two channels,
A
&
B.
These channels are further split across two sockets each,
A1/A2 & B1/B2.
The energy available from each socket is displayed. Switching of
f a socket will cause
the unit to dump the energy in order to maintain the remaining channel/socket.
There is no need to
manually accommodate these changes.
With Channel
A
in use only
, the full pack power is available to share between sockets
A1 and
A2.
Therefore a single head in
A1 can discharge the full 3000Ws.
With a head switched of
f in either of the Channel B sockets B1/B2, the pack automatically becomes
asymmetric. In this mode, a maximum of 2000Ws is available across channel
A
and a maximum of
1000Ws across channel B.
As you become familiar with operating the pack, you will notice short pauses in the unit returning to
ready during power adjustments.
This is because the unit always adjusts the power level to match the
displayed value for each socket.
T
urning a socket of
f, for example, requires the energy to be dumped,
hence the delay
.
A
further reason is that for any given power level, the unit will automatically optimise
the internal capacitor usage to minimise the flash duration.
Modelling Power
Modelling On/Of
f is controlled by a single button. Modelling control to each head can be set to On/Of
f
or Intermittent. (Intermittent extinguishes the lamps when the unit is not ready)
There are three modelling modes, Full, Proportional and automatic 100%.
The Full and
Automatic 100% modes also provide a bias control allowing all lamps to be controlled in
ratio.
Main Selection Controls
The commonly required adjustments are grouped under the “Main” selection menu.
This allows control over the following;-
1.
Modelling.
2.
Speaker
.
3.
IR Channel.
4.

This classic lighting accessory gives a unique full-
frontal lighting ef
fect that makes it popular among
fashion photographers.
The camera mounts to the centre of an opening
that is surrounded by two semicircular 1500Ws
flash tubes to achieve amazing results.
T
o
ensure
short, freeze-action flash duration, the flash tubes
have three, rather than two, electrodes and each
has a separate cable.
The Ringflash can be used
with any QUAD generator and its integral
mounting bracket adjusts for use with virtually all
medium format, and 35mm camera.

For refined lighting ef
fects, two quite dif
ferent
reflectors are available.
Ringflash High-Intensity Reflector
This reflector increases the overall size of the light
source, intensifying the light output.
BW2310
Ringflash Diffuser
For a softer lighting ef
fect, this opal dif
fuser can
be used with the Ringflash.
This will soften the
shadows and is perfect for most direct lighting
applications.

The fan-cooled QUADX flash head is capable of
handling up to 3000Ws and is fitted with 650W
modelling lamp.
The user changeable flash tube features a
three-electrode design to deliver the fastest
possible flash duration.
