The advanced menus provide access to system
settings and functions not required for basic
operation of the Redback.
6.1 Accessing the Advanced Menus
[ADV]
To enter the Advanced Menu system, press
Menu Down
T key until ADV LED is lit, then hold
down the 3 Flip key for two seconds. The
display changes to show the Test menu TEST,
when the Advanced Menu system is available.
Note: All settings inside the Advanced Menu are
automatically saved to memory upon exiting the
advanced menu and will be recalled when the
dimmer is powered on unless noted otherwise.
6.2 Testing the Dimmers
T E S T
The test menu allows each dimmer to be tested
independently of all other functions. The dimmer
under test responds only to the level set from
test function.
The Right
„ arrow key activates test mode and
displays the current dimmer under test.
C 1 L 4 2
In this screen:
The
ƒ Left and Right „ arrow keys select the
dimmer under test. The currently set test level is
applied to the dimmer under test.
The
Up and Down † arrow keys increase and
decrease the level of the selected dimmer.
Exiting from the test menu disables test mode
and releases all channels. Settings in the Test
Menu are not saved to memory.
6.3 Fade Curve Selection
C U R V E
The Fade Curve menu enables selection of the
relationship between the input control signal and
the actual dimmer output. Each of the available
fade curves produces a different response from
the dimmer as the channel is faded up and
down.
6.3.1 S Law Curve
S C U
The S law curve is the standard dimming curve
found on the majority of electronic dimmers in
current use. It is favoured in live applications
because its "S" shape gives plenty of gentle
adjustment at the bottom and top ends of the
channel fader where subtle fades are important,
and a rapid rise in the middle of the fader. (This
is the default curve for Redback.)
6.3.2 Square Law
S Q U
The square law curve produces a linear power
output as the fader level increases. It comes on
rapidly at the bottom end but rises more gently
after 25% on the fader, a characteristic that
matches the light response of many video
camera systems.
6.3.3 120 Volt
1 2 0
The 120 Volt curve is intended for powering
120V lamps from a 240V mains supply. It follows
the pattern of the standard S law curve, but
limits the output to 120 Volts when the control
signal is at Full.
Warning:
A Total Reset, sets all dimmers to the default S
law curve (SCU). This could result in 240 Volts
being fed to 120 Volt lamps.
6.3.4 Switching loads On and Off
Redback has two curves for switching loads
directly between ON and OFF. These curves are
useful for controlling loads that don't take kindly
to being dimmed, such as motors or discharge
lamps.
6.3.5 Non Dim
N O N
The Non Dim curve is for use when a load
needs to be switched during a fade cue.
The load is switched ON when the dimmer level
goes above 60% and switched OFF when the
dimmer level falls below 40%.
6.3.6 Relay
R L Y
The Relay curve is for use when a load needs to
be switched at the beginning or end of a fade
cue.
The load is switched ON when the dimmer level
goes above 4% and switched OFF when the
dimmer level falls below 2%.
