INTENSITY
Flash intensity can be set from minimum (blackout) to maximum on channel 1
in
the 3- and
4-channel DMX
modes.
Intensity
is
maximum
in
1-channel DMX
mode.
The
maximum intensity
can be
reduced
by
selecting
low
power mode

DURATION
Flash duration can be set from
0
to 650 ms on 50 Hz power supplies, or 0 to
530
ms on 60 Hz power supplies, on channel
2
in the 3- and 4-<:hannel DMX
modes.
Flash duration is fixed
in
1-channel DMX
mode.
RATE
Flash mte can be set from 0 flashes per second to 25 flashes per second Hz on
50
Hz power supplies, or from
0
to 30 flashes per second on 60 Hz power
supplies,
on channel 3
in
the 3- and 4-channel DMX modes. Flash mte is also
controllable
in 1-channel DMX
mode.
PROGRAMMED EFFECTS
Six
progmmmed
effects are available on channel 4 in the 4-channel DMX
mode
only.The effects may be altered using the intensity, duration, and rate
controls.
Ramp
up:Light gradually increases in intensity,then

Ramp
down:Light
flashes to

intensity,then gradually fades.
Ramp
up-down:Light gradually increases
and
decreases.

BLINDER EFFECT
The
blinder effect,
in which the light

on for an
extended period,
is
available
in
all
DMX
modes.

The Strobe 3000
provides
both
3-pin
and 5-pin XLR
sockets for
data connection. The pin-out on all sockets is pin 1 to shield, pin 2 to cold
(-),
and
pin
3 to
hot(+).
There is no connection to pins 4 and 5. The sockets are wired
in
parallel: both inputs connect to both outputs. For
