The Heart of the QUADX System.
The QUADX is a powerful, four-channel pack with precise power adjustments and dependable repeatability. With a maximum power of 3000Ws and a minimum of just 31Ws with one head - a power range of 7.6 f/stops! The QUADX offers a wide range of lighting control options with precision adjustments and a user-friendly control panel that lets you know exactly how much power is coming out of each head, the flash duration and a host of other vital statistics, all at the press of a button.

Precision Power Controls and Repeatable Performance.
Digital capturing devices require a much greater degree of exposure accuracy than film materials. The QUADX lets you control the flash output of each head in 1/10-stop increments and offers repeatable output flash after flash, which is ideal for multi-shot camera backs.

Consistent Colour and Short Flash Durations.
The unique power-management system of the QUADX constantly monitors and adjusts capacitor performance to ensure complete output accuracy and consistency, retaining a colour temperature of 5800 K, ±2%. The units capacitor switching delivers greater colour consistency over the entire power range in addition to providing flash durations as short as 1/1430 sec. with a single head at full power (1/7100 sec. with two heads at 250Ws).

Most Efficient Charging System.
The QUADX features an advanced charging system that is extremely efficient and extends the life of the pack’s capacitors. The automatic mode provides a slow initial charge when the unit is switched on and then, by monitoring the temperature of the capacitors, offers the fastest possible recharging times.

The QUADX Control Panel.
The control panel of the QUADX is simple and intuitive to use. Power is divided into two independent channels, A and B, one having a maximum power of 2000Ws (A), the other (B) 1000Ws. Each channel controls two flash-head outlets in 1/10-stop increments. When more than one head is used in the same channel, the power of that channel will be divided equally between those two heads. When a head is connected to Channel B, the pack automatically becomes asymmetric. Once lighting ratio or contrast levels are set, power level adjustments can be made to acheive perfect exposures.

Advanced QUADX Features
With its sophisticated circuitry, the QUADX gives the photographer access to many advanced features including trigger delay, flash counter, joules/percentage display, multi-flash mode, memory function and more. Other features offered by the QUADX include:

Auto Bracketing
Bracketing flash exposures is easy with the QUADX. You can set up to three bracketing intervals from 1/10 to 9/10-stop and monitor the bracketing sequence and see what each power level will be on the LCD display.
Infrared Remote

The QUADX features an IR remote control system that allows the photographer full control of the pack from up to 10m (30').
Head Failure Indication

Special Effect Modes
Choose from trigger delay, trigger skip and multi-trigger setup to fire up to nine packs at different intervals or sequentially.
