Testing the Monolight
Press the transmitter’s test button to test-re the monolight.
Preash Variation Settings
The Impact Digital Monolight is compatible with nearly all master ash slave
units. Different brands use different numbers of pre-ashes before triggering
other slave units. To facilitate those differences, this studio ash has two
settings that enable the ash to ignore a user-selected timeframe of pre-ashes
before ring. Use these functions when you need to manually control pre-ash,
instead of using the “Slave and Pre-Flash Settings” mode.
NOTE: As different brands of ashes have different numbers and durations of
their pre-ashes, some trial and error may be necessary to obtain your model’s
best settings.
Time Frame
The Time Frame function allows for a variable of 1 to 5 seconds for the studio
ash to ignore master pre-ashes. To use this function, refer to the following
instructions:
1. Press and hold the slave button for 8 seconds.
2. Use the or modeling light output buttons to select your required
setting.
20

NOTE: The default setting of this function is t2, which means the ash will only
be triggered after 2 seconds of pre-ashes. When using multiple speedlites with
different pre-ash frequencies, this mode will group all the ashes as one before
ring.
Block Time
The Block Time function allows for a variable of 1 to 18 milliseconds for the
studio ash to ignore master pre-ashes. In this mode, your monolight will begin
to record and learn to recognize your device’s pre-ashes. This is to compensate
for the different pre-ash timing between devices. To use this function, refer to
the following instructions:
Press and hold the slave button for 8 seconds.
Press the slave button again.
Use the or modeling light output buttons to select your required setting.
