SAFETY
Thank you for selecting the Martin MAC 250 or the MAC 250+. Both the MAC 250 and the MAC 250+ are yokemounted profile spotlights that are designed around a 250 watt discharge lamp. They provide:
• 12 saturated dichroic colors
• 8 replaceable rotating gobos
• 3-facet rotating prism
• variable focus
• strobe effects
• 0 to 100% dimming
• accurate 16-bit movement.
In addition, the standard MAC 250 provides 4 user-configurable beam angles from 12.1° to 23.3°. The MAC 250
vides gobo indexing, interchangeable color filters , and an 18.3° achromatic lens syste m. High-performance optics,
attractive design, modular construction and numerous user-friendly features make these Martin fixtures well suited for
any effect lighting applic at ion callin g for a compa ct , hard-fo c using 25 0 watt fixture.
Safety precautions
The MAC 250 and MAC 250+ are for professional use only. They are not for household use. They present risks of
injury due to electric shock, heat and ultraviolet radiation burns, lamp explosion, falls, high-intensity light, and fire.
Read this manual before powering or installing the fixture, follow the safety precautions listed below and observe
all warnings in this manual and printed on the fixture. If you have questions about how to operate the fixture safely,
please contact your Martin dealer or call the Martin 24-hour service hotline for assistance.
+
pro-
• ALWAYS disconnect the fixture from AC power before removing or in stalli ng the lamp , fuses, or any part ; and whe n
not in use.
• Allow the fixture to cool for at least 5 minutes before repl acing the lamp.
• Keep all combustible materials (for example fabric, wood, paper) at least 0.3 meters (12 inches) away from the fixture.
Keep flammable materials well away from the fixture.
• For protection against dangerous electric shock, always ground (earth) the fixture electrically. Use only a source of AC
power that complies with local building and electrical codes. Do not expose the fixture to rain or moisture.
• Ensure that the air flow through fans and vents is free and unobstructed.
• When suspending th e fixture above ground level, verify that the st ructure can ho ld at least 10 times t he weight o f all
installed devices and secu re the fixture with an ap proved safety cable. Block access below the work area whenever
installing or removing the f ixtu r e.
• Refer any service operation not described in this manual to a qualified technician.
• Do not illuminate surfaces within 0.3 meters (12 inches) of the fixture.
• Never place filters or other materials over the lens.
• Do not operate the fixture if the ambient temperature (Ta) exceeds 40° C (104° F).
• Replace the lamp as soon as it becomes defective or worn out, or before usage exceeds the maximum service life.
• Do not stare directly into the light.
• Never operate the fixture without all lenses and covers installed: an unshielded lamp can explode without warning and
emits dangerous UV radiation that can cause burns and eye damage.
• Do not modify the fixture or install ot her than genuine Martin accessories and upgrade kits.

The MAC 25 0 and MAC 250+ include a clamp mounting bracket to which 1 or 2 riggin g clamp s (no t include d) can be
bolted. The clamp mounting bracket fastens to the base as shown with 1/4-turn fasteners.
Figure 2: Clamp mounting bracket
WARNING!
Always use an approved safety cable.
The 1/4-turn fasteners are locked only when turned fully clockwise.
Ver ify that the clamps are in good condition and can bear at least 10 times the weight of the fixture. Bolt
clamps to the bracket with a grade 8.8 (minimum) M12 bolt and lock nut, or as recommended by the clamp
manufacturer, through the 13 mm holes in the clamp mounting bracket.
Align the clamp mounting bracket with any 2 key slots on the base. Insert both locking pins into the
slots and turn both levers a full 1/4 turn clockwise to lock.
Ver ify that the structure can bear at least 10 times the weight of all installed fixtures, clamps, cables,
auxiliary equipment, etc.
Working from a stable platform, clamp the fixture to the structure.
Install a safety cable that can bear at least 10 times the weight of the fixture securely to the structure
and anchor the cable to the dedicated attachment point on the base. The attachment point is
designed to fit a carabiner clamp.

Tips for building a serial link
• Use shielded twisted-pai r cable designed for RS -485 devices: standard micropho ne cable cannot t ransmit DMX data
reliably over long runs. For links up to 300 meters (1000 ft.) long, you can use 24 AWG, low capacitance, 85- 150 ohm
characteristic impeda nce, shi elded ca ble with 1 or mo re twisted pairs. F o r runs up to 50 0 mete rs (1640 ft. ) use 2 2 AWG
cable. Use an amplifier if the serial link exceeds 500 meters.
• Never use a “Y” connector to split the link. To split the serial link into branches use a splitter such as the Martin 4Channel Opto-Isolated RS-485 Splitter/Amplifier.
• Do not overload the link. Up to 32 devices may be connected on a serial link.
• Terminate the link by installing a termination plug in the output socket of the last fixture on the link. The termination
plug, which is simply a male XLR connector with a 120 ohm, 0.25 watt r e sistor soldered between pins 2 and 3, “soaks
up” the control signal so it does not reflect back down the link and cause interference. If a splitter is used, terminate
each branch of the link.

OPERATION
This section describes the effects and how personality settings affect their behavior. Selecting personalities from the
control panel is described in the previous section.
DMX-512 control
The MAC 250 and MAC 250+ can be operated with DMX-512 controllers in 4 modes that combine vector and/or tracking control with 8-bit or 16-bit pan/tilt resolution.
Tracking control
With tracking control, the speed at which effects move is set by programming a cross-fade time on the controller. The
controller divides the move into steps and updates the fixture with small changes at the rate required to achieve the
fade. The fixture tracks the changes and averages them with a digital filter algorithm to provide smooth movement at
all speeds.
This algorithm is adjustable to compensate for controllers that calculate position changes unevenly. In most cases the
default settings work well. If movement is not satisfactory there are 2 parameters that can be adjusted. The first is the
calculation method used and is selected under
on the absolute value of the change in DMX; it is the best choice with controllers that calculate intermediate positions
that are close to the li ne of trav el. MOd 2 uses the real value of the DMX delta to calculate speed and is better if the
intermediate positions stray significantly from the line of travel.
PERS/TRAC/MOdE. MOd1, the defau lt, calculates speed based
The second parameter is the number of position updates used to calculate speed. The level is adjustable between 1 and
10 under
lated, making move ment smoother but less responsive to sudden changes.
The ideal settings for both parameters will vary from controller to controller: experiment for best results.
PERS/TRAC/CAL. Increasing the number of samples increases the distance over which speed is calcu-
Vector control
With vector control, yo u set the speed on a speed channel. This provides a way to control speed on controllers without
cross-faders. Vector control also provides smoother movement , particula rly at slow speeds, wit h controll ers that send
slow or irregular tracking updates, plus a “blackout speed” and overrides of the shortcut and pan/tilt speed personality
settings. When using vector speed, the cross-fade time must be 0.
Tracking control can be enab led in vector mode by setting one or both of the speed channels to “tracking speed.”
8-bit versus 16-bit pan/tilt resolution
With 8-bit pan/tilt resolution, pan and tilt are divided into 256 equal increments. Finer position control and smoother
movement are provided in 16-bit mode, which divides pan into 40,192 positions and tilt into 43,008 positions.
Martin RS-485 control
The MAC 25 0 is ful ly suppor ted by t he Martin 3032 co ntroller wi th ve rsion 2. 05 or hi gher softw are. The MA C 250
may be set up on the 3032 as a MAC 250: gobo ind exing, however, is not sup ported . To respond to the 3032, M artin
mode must be selected or automatic protocol detection must be enabled as described on page 10.

lamps one at a time at 5 second intervals.
The fixture automatically strikes the lamp within 90 seconds of being powered on if the Automatic Lamp On setting
PERS/ALON) is turned on. A delay determined by the fixture address staggers lamp strikes to prevent excessive
(
voltage drop and curr ent draw.
The lamp can be turned off from the controller. Note: the lamp cannot be restruck for 8 minutes after being turned off.
Accidental “lamp off” commands can be prevented by turning the DMX Lamp Off setting (

BASIC SERVICE
The MAC 250 and MAC 250+ operate under challenging conditions presented by heat, humidity, dust, and touring.
Excessive dust, grease, and smo ke fluid b uildu p degr ades perfo rman ce and cau ses overhe at ing an d damag e that is not
covered by the warranty. The MAC 250 and MAC 250+ require regular maintenance to keep performing at their peak.
The schedule wi ll depen d on th e applica tion and should be dis cussed wit h your Martin di stribut or. Refer any servic e
that you are not qualified to perform to a profession al techn ic ian.
Removing covers exposes dangerous live electrical circuits, hot surfaces, and a
lamp under high pressure. Procedures requiring the removal of any cover shall
be performed by professional users or technicians only. Disconnect the fixture
from AC power and allow it to cool before removing any cover.
Replacing the lamp
If the lamp becomes difficult to strike, it probably needs to be replaced. To reduce the
risk of lamp explosio n, which may damage the fixture, do not excee d the lamp’s rated
life (2000 hour s) by more than 25 percent.
WARNING!
Refer to page 5 for the lamp replacement procedure. After installing the lamp, reset the
lamp usage counters as described on page10.
Optimizing reflector alignment
The reflector is aligned at t he factory. Due to differences be tween l amps, h owever, fine
adjustment may improve performance.
Strike the lamp and focus the light on a flat surface.
1.
See Figure 1 on page 4. Center the hot-spot (the brightest part of the
2.
beam) by turning the 3 adjustment screws one at a time with a 3 mm Allen
wrench. If there is no hot-spot, adjust the reflector until the light is even.
To reduce a hot-spot, “push” the reflector out by turning all 3 screws coun-

terclockwise 1/4-turn at a time until the light is evenly distr ibuted.
If the light is brighter around the edge than it is in the center, or if light out-

put is low, the lamp is too far back in the reflector. “Pull” the reflector in by
turning the screws clockwise 1/4-turn at a time until the light is bright and
evenly distributed.
Rotating gobos
Custom glass gobos for the MAC 250 and MAC 250+ should be made with any
non-reversible graphics true on the coated side. Complete gobo specifications are
listed on page 27. Do not use ch rome -coate d glass gob os: the y absorb more h eat
than enhanced aluminum gobos and are likely to break or oxidize.

Cleaning
Optical components
Use care when cleaning optical components. The surface on dichroic filters is achieved by means of special multi-layer
coatings and even small scrat ches may be visible. Residue s from clea ning fluid s can bak e onto com ponents an d ruin
them.
Allow the components to cool completely.
1.
Wash dirty lenses and filters with isopropyl alcohol. A generous amount of regular glass cleaner may
2.
also be used, but no residues may remain.
Rinse with distilled water. Mixing the water with a small amount of wetting agent such as Kodak
3.
Photoflo will help prevent streaking and spotting.
Dry with a clean, soft and lint-free cloth or blow dry with compressed air.
4.
Fans
To maintain adequate cooling it is important that the fans be cleaned of dust and dirt periodically. Use a soft brush, vacuum, or compressed air .
Lubrication
Use silicone lubricant, Mart in P/N 37 30 200 3 (50 0 ml) or P/N 3730 20 04 (20 0 ml, i n appl ic ator bott le) . No ot her lubr icant is approved for use. When applying lubricant, always remove excess and do not get oil on other parts.
Check the focus mechanism when the head is open and apply a drop of lubricant to the 3 metal slides if movement is
rough.
Lubricate the rotating-gobo bearings if movement is rough on slow rotation or if they become noisy. Apply a few drops
of oil to each bearing from the lamp side of the wheel.

Troubleshooting
Problem Probable cause(s) Remedy
One or more of the fixtures
is completely dead.
Fixtures reset correctly but
all respond errat ically or not
at all to the controller.
Fixtures reset correctly but
some respond erratic al ly or
not at all to the controller.
Magnetically indexed effect
resets correctly but wanders after fixture reaches
operating temperature.
No light and “LERR” error
message displayed.
Lamp cuts out intermittently.
No power to fixture.
Primary fuse blown. Replace fuse.
Secondary fuse(s) blown (located on
PCB inside base).
The controller is not connected. Connect controller.
XLR pin-out of the controller does not
match pin-out of the first fixture on the
link (i.e. signal is reversed).
Bad data link connection
Data link not terminated with
mination plug.
Incorrect addressing of the fixtures. Check addr ess and protocol settings.
One of the fixtures is defective and disturbs data transmission on the link.
XLR pin-out on fixtures does not match
(pins 2 and 3 reversed).
Effect wheel or magnetic sensor
requires mechanical adjustment.
The ballast and transformer setting s do
not match local AC voltage and frequency.
Lamp missing or blown Disconnect fixture and replace lamp.
Fixture is too hot.
The ballast and transformer setting s do
not match local AC voltage and frequency.
120Ω
Check that po w er is s w itc hed on a nd cab l es are
plugged in.
Check fuses on PCB and replace.
Install a phase-reversing cable between the
controller and the first fixture on the link.
Inspect connections and cables. Correct poor
connections. Repair or replace damaged
cables.
ter-
Insert termination plug in output jack of the last
fixture on the link.
Bypass one fixture at a time until normal operation is regained: unplug both connectors and
connect them directly together. Have the defective fixture serviced by a qualified technician.
Install a phase-reversing cable between the fixtures or swap pins 2 and 3 in the fixture that
behaves erratically.
Disable effects feedback. Contact Martin technician for service.
Disconnect fixture. Check ballast and transformer settings and correct if necessary.
Allow fixture to cool.
Reduce ambient room temperature.
Recalibrate temperature sensors.
Check ballast and transformer settings and correct if necessary.
