Optic S1 Secondary Unit Setting

In M manual flash mode, press < S1/S2 > button so that this flash can function as an optic S1 secondary flash with optic sensor. With this function, the flash will fire synchronously when the main flash fires, the same effect as that by the use of radio triggers. This helps create multiple lighting effects.

Optic S2 Secondary Unit Setting

Press < S1/S2 > button so that this flash can also function as an optic S2 secondary flash with optic sensor in M manual flash mode. This is useful when cameras have pre-flash function. With this function, the flash will ignore a single "preflash" from the main flash and will only fire in response to the second, actual flash from the main unit.

S1 and S2 optic triggering is only available in M manual flash mode.

Display Flash Duration

Flash duration refers to the length of time that from flash's firing to reach the half peak at maximum. The half peak at maximum is usually expressed as t=0.5. In order to provide the photographer with more concrete data, this product adopts t=0.1. The difference between t=0.5 and t=0.1 is shown in the following picture.

In M/Multi mode which without high-speed sync, flash duration is displayed on the LCD panel.

Flash Mode — Multi: Stroboscopic Flash

With stroboscopic flash, a rapid series of flashes is fired. It can be used to capture a multiple images of a moving subject in a single photograph.
You can set the firing frequency (number of flashes per sec. expressed as Hz), the number of flashes, and the flash output.

1. Press <MODE> button so that <MULTI> is displayed.
   
2. Set the flash frequency and flash times.
   
   • Press Function Button 3 < > button to select the flash times. Turn the Select Dial to set the number.

   • After you finish the setting, press <SET> button and all the settings will be displayed.

Calculating the Shutter Speed

During stroboscopic flash, the shutter remains open until the firing stops. Use the formula below to calculate the shutter speed and set it with the camera.

Number of Flashes / Flash Frequency = Shutter Speed

For example, if the number of flashes is 10 and the firing frequency is 5 Hz, the shutter speed should be at least 2 seconds.

To avoid overheating and deteriorating the flash head, do not use stroboscopic flash more than 10 times in succession. After 10 times, allow the camera flash to rest for at least 15 minutes. If you try to use the stroboscopic flash more than 10 times in succession, the firing might stop automatically to protect the flash head. If this happens, allow at least 15 minutes' rest for the camera flash.

Stroboscopic flash is most effective with a highly reflective subject against a dark background. Using a tripod and a remote control is recommended. A flash output of 1/1 and 1/2 cannot be set for stroboscopic flash. Stroboscopic flash can be used with "buLb". If the number of flashes is displayed as "--", the firing will continue until the shutter closes or the battery is exhausted. The number of flashes will be limited as shown by the following table.

Maximum Stroboscopic Flashes:

If the number of flashes is displayed as "--", the maximum number of flashes will be as shown in the following table regardless of the flash frequency.

Wireless Flash: Optic Transmission

This product supports wireless flash application and functions as either a master or a slave unit. As a master unit, it can control Canon speedlites e.g. 580EXII, 600EX-RT via wireless. As a slave unit, it can receive wireless signals of Canon speedlites e.g. 580EXII, 600EX-RT and commanders of Canon cameras e.g. 7D/60D/600D.

• You can set up two to three slave groups for E-TTL II autoflash shooting. With E-TTL II autoflash, you can easily create various lighting effects.
• Any flash settings (of flash exposure compensation, high-speed sync, FE lock, FEB, manual flash, Multi flash) on the master unit will be automatically sent to the slave units. So the only thing you need to do is to set the master unit to ETTL mode without any operation for the slave units at all during the shooting.
• This flash can work in ETTL autoflash, M manual flash, and Multi stroboscopic flash modes when set as a master unit.

Positioning and Operation Range

Even with multiple slave units, the master unit can control all of them via wireless. In this user manual, "master unit" refers to the camera flash on a camera and "slave unit" will be controlled by the master unit.

Using a flash (master/slave) with a radio transmission wireless shooting function make it easy to shoot with advanced wireless multiple flash lighting, in the same way as E-TTL II autoflash shooting.
The basic relative position and operation range are as shown in the picture. You can then perform wireless E-TTL II /ETTL autoflash shooting just by setting the master unit to <ETTL>.
AD360II-C adopts Godox 2.4G wireless X system, which can be used in combination with other products in our factory.
As a slave unit, AD360II-C is compatible with Canon E-TTL II and Nikon i-TTL systems. It will automatically change its system according to the master unit instead of setting by manual. Once received the master unit's signal, "Canon" or "Nikon" is displayed the LCD panel.
Nikon cameras (use X1T-N, TT685N, etc) and Canon cameras (use X1T-C, TT685C, etc) can use one or more AD360II-C flashes simultaneously.

* As master unit, AD360II-C can control the following slave units: AD360II-C, AD360II-N, TT685C, X1R-C, TT600, etc.
* As slave unit, AD360II-C can be controlled by the following master units: AD360II-C, AD360II-N, TT685C, TT685N, X1T-C, X1T-N, TT600, etc.

Positioning and Operation Range

(Example of wireless flash shooting)

• Autoflash Shooting with One Slave Unit
  

Use the supplied mini stand to position the slave unit. Before shooting, perform a test flash and test shooting. The transmission distance might be shorter depending on the conditions such as positioning of slave units, the surrounding environment and whether conditions.

Wireless Multiple Flash Shooting

You can divide the slave units into two or three groups and perform E-TTL II/E-TTL autoflash while changing the flash ratio (factor). In addition, you can set and shoot with a different flash mode for each firing group, for up to 5 groups.

• Auto Shooting with Two Slave Groups
  
• Auto Shooting with Three Slave Groups
  

Wireless shooting using radio transmission has advantages over wireless shooting using optic transmission, such as being less affected by obstacles, and not having to point the slave unit's wireless sensor toward the master unit. The main functional differences are as follows:

Function		Radio Transmission	Optic Transmission
Distance		70m	Master (transmitter): approx. 3m; Slave (receiver): approx. 15m
Channel		1~32	1~4
A/B/C Power		OFF, 1/128~1/1	1/128~1/1
To be disturbed		Hard	Easy
The Reason & Solution of Not Triggering in Godox 2.4G Wireless
Disturbed by the 2.4G signal in outer environment (e.g. wireless base station, 2.4G wifi router, Bluetooth, etc.) To adjust the channel CH setting on the flash trigger (add 10+ channels) and use the channel which is not disturbed. Or turn off the other 2.4G equipment in working. Please make sure that whether the flash has finished its recycle or caught up with the continuous shooting speed or not (the flash ready indicator is lighten) and the flash is not under the state of over-heat protection or other abnormal situation. Please downgrade the flash power output. If the flash is in TTL mode, please try to change it to M mode(a preflash is needed in TTL mode). Whether the distance between the flash trigger and the flash is too close or not Please turn on the "close distance wireless mode" on the flash trigger ( X1 series: press the test button and hold on, then turning it on until the flash ready indicator blinks for 2 times. XPro series: Set the C.Fn-DIST to 0-30m. Whether the flash trigger and the receiver end equipment are in the low battery states or not Please replace the battery (the flash trigger is recommended to use 1.5V disposable alkaline battery).

Other Applications

Wireless Control Function

The flash unit is built in with a Wireless Control Port so that you can wirelessly adjust the power level of the flash and the flash triggering. To control the flash wirelessly, you need a FT-16 remote control set (on camera and on-flash). Insert its receive end into the Wireless Control Port on the flash and insert the transmit end into the camera hot shoe. Settings made on the hotshoe-mounted transmit and receive ends will be wirelessly communicated to the flash. Then you can press the camera shutter release button to trigger the flash. You can also hold the transmit end at hand to control your off-camera flash.

For full instructions on the use of FT series remote control, see its user manual.

Modeling Flash

If the camera has a depth-of-field preview button, pressing it will fire the flash continuously for 1 second. This is called modeling flash.
It enables you to see the shadow effects on the subject and the lighting balance. You can fire the modeling flash during wireless or normal flash shooting.

To avoid overheating and deteriorating the flash head, do not fire the modeling flash for more than 10 consecutive times. If you fire the modeling flash 10 consecutive times, allow at least 10 minutes' break for the camera flash. The modeling flash cannot be fired with the EOS 300 and Type-B cameras.

Auto Focus Assist Beam

In poorly-lit or low-contrast shooting environments, the built-in auto focus assist beam will automatically light on to make it easier for autofocus. The beam will light up only when autofocus is difficult and get out as soon as the autofocus becomes correct.
If you want to turn off the auto focus assist beam, set the "AF" to "OFF" on the C.Fn settings.

If you find the auto focus assist beam does not light up, this is because the camera has got a correct autofocus.
Position	Effective Range
Center	0.6~10m / 2.0~32.8 feet
Periphery	0.6~5m / 2.0~16.4 feet

Assist Beam Setting

The flash has two ways to light on the assist beam: auto focus (AF) and manual focus (MF). Press Function Button 1 (MF/C.Fn) to choose.
Auto focus (AF): The assist beam is lighted on by camera.
Manual focus (MF): The assist beam is lighted on manually.
Turn off the assist beam: Set "AF" to OFF on the C.Fn menu, and the assist beam will be turned off.

Bounce Flash

By pointing the flash head toward a wall or ceiling, the flash will bounce off the surface before illuminating the subject. This can soften shadows behind the subject for a more natural-looking shot. This is called bounce flash.

To set the bounce direction, hold the flash head and turn it to a satisfying angle.

• If the wall or the ceiling is too far away, the bounced flash might be too weak and result in underexposure.
• The wall or the ceiling should be a plain, white color for high reluctance. If the bounce surface is not white, a color cast may appear in the picture.

Sync Triggering

The Sync Cord Jack is a Φ3.5mm plug. Insert a trigger plug here and the flash will be fired synchronously with the camera shutter.

PC Sync Socket Triggering

Use remote cable to connect the camera and the AD360II-C through its PC sync socket, and the flash will be fired synchronously with the camera shutter.

If flash exposure compensation has already been set with the camera flash, flash exposure compensation cannot be set with the camera. To set it with the camera, the camera flash's flash exposure compensation must be set to zero. If any Flash Custom Functions and flash settings other than flash exposure compensation have been set by both the camera and the flash, the latest settings will take effect.

Protection Function

Over-Temperature Protection

• To avoid overheating and deteriorating the flash head, do not fire more than 75 continuous flashes in fast succession at 1/1 full power. After 30 continuous flashes, allow a rest time of at least 75 minutes.
• If you fire more than 75 continuous flashes and then fire more flashes in short intervals, the inner over-temperature protection function may be activated and make the recycling time over 10 seconds. If this occurs, allow a rest time of about 10 minutes, and the flash unit will then return to normal.
• When the over-temperature protection is started, is shown on the LCD display.
