DO NOT ATTEMPT TO LOCATE AND REPLACE THE INTERNAL FUSE YOURSELF. • Control Panel Lights Up But Ready Indicator Does Not Light Up If this happens, first confirm that the AC-line voltage is adequate and within the prescribed limits. Confirm that the Flash Thermal Reset Button on the Rear Panel is pushed in. Under exceptional conditions of use, this may trip. Switch the unit off, wait a minute, push the button in and then switch power on again. • Modelling Lamps Are Not Working If all of the modelling lamps are not working, first check to see if the Modelling Thermal Reset Button on the Rear Panel is out. If this is the case, DO NOT RESET IT until you have checked the head(s) for blown bulbs and/or fuses. • Power Pack Triggers Erratically Check to see if the power pack is being triggered by another flash source by turning the photocell off. 4 9 Getting Started Control Panel Before first using your power checked for basic operation as 1. Remove the packaging and ensure 2. Set up a flash head. Be sure the protective on. 3. Plug the head into the socket of Channel A. 4. Set the Overall Power Selector to Symmetric/2400 5. Set the Modelling Mode Selector to Intermittent/Proportional. 6. Set Audio Switch to On, Photocell Switch to Off and Fast/7. Connect the power pack to a 230V AC, 50/60Hz outlet using 8. Set the Power On/Off Switch to On. The unit will show “2400” on charge to this setting. 9. Confirm after a few seconds that the Ready Indicator lights up, the Audio flash head’s Modelling Light is on at Full brightness. 10. Use the Test Button to discharge the set power into the head. 11. Confirm that the head flashes, the power pack recycles and Ready Indicator lights 12. Repeat steps 8 and 9 with the Overall Power Selector set to Symmetric/1200, Symmetric/Asymmetric/1200, Asymmetric/600 and Asymmetric/300. Confirm that there is an appropriate light output with each change of setting. Use a flash meter if possible. 13. Reduce the Channel A Variator setting to -3.0 and confirm that the Modelling Light has dimmed. 14. Confirm that the head flashes, the power pack recycles and Ready Indicator lights up. 15. Switch the power pack off. Plug the head into channel B. 16. Set the Overall Power Selector to Asymmetric/1200 and both Channel Variators to Full. 17. This time both numeric displays will show “1200.” The power pack will now charge to this setting. 18. Confirm after a few seconds that the Ready Indicator lights up, the Audio Ready Signal beeps, and the flash head’s Modelling Light is on at Full brightness. 19. Use the Test Button to discharge the set power into the head. 20. Confirm that the head flashes, the power pack recycles and the Ready Indicator lights up. 21. Repeat steps 16 to 19 with the Overall Power Selector set to Asymmetric/600 and Asymmetric/300. Confirm that there is an appropriate change of light output with each change of setting. Use a flash meter if possible. You are now ready to begin using the generator. NOTE: If the unit has been left unused for six months or predominantly used with low power settings, it is recommended that the Power Level be increased to Maximum and the unit left switched on for at least 30 minutes occasionally to help preserve the life of the capacitors. 8 Power On/Off Switch common to both channels. NOTES: 1 The QUAD2400 displays the power available to each channel in watt-seconds on the two red numeric Power Level Displays marked Channel A and Channel B. 2 Beneath the Channel Power Level Displays are the Channel Variators. These control the individual power available from the Head Sockets A and B in 1/ 3 stop increments. NOTE: The individual Channel Variators and Power Level Displays are aligned with the associated socket. 3 The Fast/Slow Switch, Overall Power Selector and Modelling Mode Selector are AC Inlet 230VAC 50/60Hz 16A Flash Thermal Reset Button Modelling Thermal Reset Button The AC Inlet, On/Off Switch and Thermal ResetButtons are mounted on the rear panel.

A single Overall Power Selector reduces Channel Variator controls reduce each channel’s 1/3-stop steps. The Overall Power Selector has settings for both Asymmetric The selected power in Asymmetric mode is available any head is fitted in the other channel. The power available Channel Variator and the associated display. The full selected power in Symmetric mode is only available from fitted in the Channel B socket. The total power available is shown Display and is controllable by means of the Channel A Variator only. In general, the Overall Power Selector should be set to the lowest setting set to the highest, consistent with the flash power and the distribution between This method provides the shortest flash duration for a given power outp...
