INTRODUCTION
Congratulations on your new TwinSpin II. It will add an exciting new dimension to your pattern
projections: motion. Now you can create dynamic special effects quickly and easily.
PREPARING THE FIXTURE
Before inserting patterns or a TwinSpin II in your fixture, it is important to align the lamp. Position it
in the reflector so that the circle of light is as smooth and even as possible. When the field of light is
truly flat, it will appear a tiny bit darker in the center (this is an optical illusion).
When the lamp is positioned too far into the reflector, the center of the field will look hot. When the
lamp is positioned too far back out of the reflector, the center will be dull and shadowed and the
outer rim will look bright and harsh. 'Hot spots' cause premature warping of the patterns and may
damage delicate designs.
INSERTING PATTERNS IN THE TWINSPIN
With TwinSpin II lying on a flat surface, center a pattern in the shallow well on the lip of the circular
opening. Then secure with a retaining ring.
Begin by pushing one end of the ring into the groove in the corner of the lip. Hold firmly in
place with your finger, pressing the ring against the pattern.
Holding the ring firmly, work the ring around until it is all in place .
Finally, allow the hooked end to snap into place. To avoid pinching your finger, hold a small
screwdriver straight against the wall of the lip near where the notched end will land. You may
press the ring down gently with your finger to make sure it is tight all the way around. Turn
TwinSpin II over and repeat on other side.

TIP
When using older warped patterns, be sure they are bent away from each other in the TwinSpin so
they can't catch on each other while rotating.
INSERTING TWINSPIN II IN THE FIXTURE
First, be sure that the lamp is properly aligned. Then slide the TwinSpin II straight down into the iris
slot just in front of the pattern holder. Be sure it is seated straight and as far down as it will go.
Secure the TwinSpin II cord so it does not contact the fixture housing.
CONTROL
USING LINE VOLTAGE - You can plug your TwinSpin II transformer directly into any 120V AC line and
the patterns will rotate at full speed.

USING A DIMMER - To easily start, stop, and adjust the rotation speed, plug your TwinSpin II into a
dimmer. Most types (even inexpensive household dimmers) will work, although speed range and
resolution may vary. Electronic dimmers slightly clip the top and/or bottom of the speed range, but
offer good resolution. The best results are produced by autotransformers.
TURN-ON and HANG-UPS
When the patterns in your TwinSpin are new, you must burn them in before rotating for the first
time. Do this by placing TwinSpin II (with the patterns mounted) in the fixture. Run the lamp at full
for approximately two minutes. Do not rotate the TwinSpin II. If you do not burn them in before
rotating, the patterns will most likely jam. If your patterns catch on each other, or if the retaining
ring is not properly secured and slips, the TwinSpin II may jam and stop turning. Turn off motor as
soon as possible to prevent freezing. Remove the unit to correct the problem, reassemble, then
resume operation.
REMOVING TWINSPIN II FROM THE FIXTURE
It is best to allow your fixture and patterns to cool naturally before removing the TwinSpin II from
the fixture. Pulling it out 'hot' will cause warping and possible tearing of the patterns due to the quick
temperature change. Lift the TwinSpin II straight out of the iris slot. Take care that the handle of the
pattern holder behind it doesn't press against the patterns and dent them.
REMOVING PATTERNS FROM THE TWINSPIN II
To remove a pattern from the TwinSpin II, use a small pocketknife blade or flathead screwdriver.
With the tool, pry the notched end of the retaining ring out of the groove, IN toward the center, and
UP. Pop the ring out of the groove, and remove ring and pattern with your fingers. Tip: hold ring
lightly with finger to prevent flyaway.

QUICK CHANGES
If you are under pressure and need to change hot patterns in your TwinSpin, be prepared with a hot
pad or gloves. The elements will be too hot to handle. It is helpful to have an extra set of rings
handy.
SPIN DESIGN
TwinSpin II provides four design options. You may rotate a single pattern, two of a kind, or two
different designs. The fourth option is to use one or two rotating patterns to animate a 'still' which is
placed in the pattern holder. Check out the Shadow Play Catalog for the hundreds of Great American
Patterns available.
CAUTION
TwinSpin II is not intended for continual use in conventional 1000W ellipsoidal spotlights. For
continuous operation applications we suggest the new cool beam units such as the ETC Source IV or
the Altman Shakespeare.
