Q1 multiple-choice · fomei-led-models Which FOMEI LED DMX model produces 600 W of output?
Explanation: The “B” suffix indicates the 5600 K daylight chip variant. Numbers correspond to wattage: 150B = 150 W, 300B = 300 W, 600B = 600 W. There is no 1200B model in the LED DMX line.
Q2 multiple-choice · fomei-led-modes Which FOMEI LED DMX control mode is used for direct intensity adjustment (the daily operator mode)?
Explanation: CCT (Correlated Color Temperature) mode is the default and exposes intensity adjustment + CCT selection. Scene mode is for video effects (lightning, fire, TV flicker). DMX mode is for networked control.
Q3 multiple-choice · led-fan-cap A FOMEI LED DMX panel’s intensity is capped at 50 %. What is the most likely cause?
Explanation: When the fan is OFF (silent mode), the panel limits intensity to 50 % to prevent thermal damage. Enable the fan to unlock full power.
Q4 multiple-choice · digital-pro-x On a FOMEI Digital Pro X, how do you turn the modeling light OFF entirely?
Explanation: Single press = max brightness; two presses = min brightness; three presses = OFF ; four presses = restore last value. Operators commonly miss this and end up with modeling at max instead of off.
Q5 multiple-choice · dpx-channels A studio has two adjacent rooms running Digital Pro X strobes. The wireless triggers from Room A are firing Room B’s strobes. What is the fix?
Explanation: The Digital Pro X XB Group/Channel system specifically prevents cross-firing. Each studio assigns a unique Group name + Channel number; wireless triggers only fire strobes on the matching Group+Channel.
Q6 multiple-choice · broncolor-modes Which Broncolor Siros WiFi mode integrates the strobes into the studio’s existing WiFi network?
Explanation: Enterprise mode joins the Siros to the studio’s WiFi router. Private mode creates a Siros-only access point (SSID Bron-Studio1). For production studios with infrastructure, Enterprise mode + separate subnet is the recommended path.
Q7 multiple-choice · broncolor-pairing In the Broncolor Siros factory-reset sequence, how long do you hold the TEST button?
Explanation: Holding TEST for 10 seconds factory-resets the entire light. This is the first step in the standard pairing sequence (followed by power cycle, wifi menu, SY confirm, BronControl pairing).
Q8 multiple-choice · siros-wifi-icon After successfully connecting a Broncolor Siros to a studio WiFi via Enterprise mode, what color should the WiFi icon on the Siros become?
Explanation: Blue = WiFi mode active but no network connected (Private mode access point or unconnected). Magenta = successfully connected to an Enterprise network. If the icon stays blue after pairing, return to the pairing sequence and retry.
Q9 multiple-choice · network-channel What WiFi channel does PhotoRobot recommend for the Broncolor lighting subnet’s access point?
Explanation: PhotoRobot’s recommended TP-Link access point configuration uses Channel 9 with 20 MHz width (40 MHz possible after interference check). Tested for compatibility with the RFS 2.4 GHz sync. Don’t change to 1/6/11 unless interference forces it.
Q10 multiple-choice · network-router Which router does PhotoRobot recommend for the Broncolor lighting subnet?
Explanation: The Mikrotik RB1100AHx4 with WiFi Radio OFF + TP-Link TL-WR802N as AP is PhotoRobot’s tested setup for the Broncolor lighting subnet.
Q11 true-false · rfs-trigger The Broncolor RFS 2.1 transceiver connects directly to CAPP and CAPP uses it for both shutter trigger AND power management.
Explanation: The RFS 2.1 is only a wireless shutter trigger — it lives on the camera hot-shoe and fires the Siros strobes when the shutter triggers. CAPP communicates with the Siros over WiFi (Enterprise mode), not through RFS. Two independent channels: WiFi for management, RFS for millisecond-precision firing.
Q12 multiple-choice · boot-order When installing a new Broncolor Siros + Mikrotik + TP-Link setup, what is the recommended boot sequence?
Explanation: Network gear must be fully up and stable before the Siros boots. If the Siros doesn’t find the access point at boot, the connection state can stick — Siros may need a factory reset to recover. Best practice: leave network gear running 24/7; power-cycle the lights as needed.
