NSTALLATION

The MX-4 can be fastened directly to a suitable surface or to a rigging clamp by
means of its adjustable mounting bracket. It can also be placed at an angle directly
on the stage or floor using the mounting bracket as a floor stand. Do not lay the
fixture flat on its pan/tilt arms: this can cause the fixture to overheat.

If using the GE Arcstream lamp, see “To orient the Arcstream lamp for maximum
life” on page 19.

Warning! Block access below the work area before proceeding.

Warning! Always use a secure means of secondary attachment.

To rig the MX-4

1If using a rigging clamp (not included), verify that it is undamaged and can bear

at least 10 times the fixture’s weight. Bolt the clamp securely 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 hole in the center of the mounting

bracket.

2If fastening the fixture directly, verify that the hardware (not included) and

mounting surface can bear at least 10 times the fixture’s weight. The four 6.2

mm holes and/or the 13 mm hole in the mounting bracket may be used.

3 Verify that the structure can support at least 10 times the weight of all installed

fixtures, clamps, cables, auxiliary equipment, etc.

4Working from a stable platform, clamp or fasten the fixture to the structure.

5Install a safety cable that can hold at least 10 times the weight of the fixture

through/over the support and through a hole in the pan/tilt arm.

6Loosen the swivel locks and tilt the fixture to the desired angle. Turn the swivel

locks clockwise to tighten. If a swivel lock does not tighten fully, pull the handle

out, turn it counterclockwise, and retighten. Repeat as necessary.

7Verify that the fixture is located at least 0.3 meters (12 in.) away from the

surface to be illuminated and at least 0.1 meters (4 in.) from any combustible

materials. Verify that the clearance around the fan and air vents is at least 0.1

meters (4 in.). Verify that there are no flammable materials nearby.

the starter while the lamp cools.

MASTER / SLAVE OPERATION

Up to 32 MX-4s can be connected together and operated in master/slave mode in
which slave fixtures follow instructions sent from the master.

Important! Set only 1 fixture as master: damage can occur if 2 masters, or

a master and a controller, are linked together.

To set up MX-4s for master/slave operation

1Disconnect all fixtures from power.

2 Plug a data cable into the OUT socket of the first

fixture and the IN socket of the next one. Continue

connecting up to 32 MX-4s output-to-input.

DMX

OPERATION

This section describes how to set up and connect the MX-4 for operation with DMX
controllers.

6

DATA CONNECTION

A reliable data connection begins with the right cable. Standard microphone cable
cannot transmit DMX data reliably over long runs. For best results, use cable
specifically designed for RS-485 applications. Your Martin dealer can supply high
quality cable in various lengths.

CONNECTIONS

The MX-4’s XLR data sockets are wired with pin 1 to ground, pin 2 to signal ­(cold), and pin 3 to signal + (hot). This is the standard pin assignment for DMX
devices.

One or more adaptor cables may be required to connect the MX-4 to the controller
and/or other lights because many devices have 5-pin connectors and others may
have reversed signal polarity, that is, pin 2 hot and pin 3 cold.

To connect the data link

1 Connect a data cable to the controller’s data output. If the controller has a 5-pin

output, use a 5-pin male to 3-pin female adaptor cable (P/N 11820005).

2Lead the data cable from the controller to the first fixture and plug it into the

data input.

3Connect the output of the fixture closest to the controller to the input of the

next fixture. If connecting to a fixture with reversed-polarity (pin 3 cold), insert

a phase-reversing cable between the two fixtures.

4Continue connecting fixtures output to input. Up to 32 devices may be

connected on a serial link.

5Terminate the link by inserting a male termination plug (P/N 91613017) into the

data output of the last fixture. A termination plug is simply an XLR connector

with a 120 ohm, 0.25 W resistor soldered across pins 2 and 3.

1-CHANNEL DMX OPERATION

The 1-channel DMX mode provides simple remote activation of the MX-4’s stand­alone programs plus blackout and strobe functions. The 1-channel functions are
shown in Table 5. Each fixture runs its own program and therefore cannot be
synchronized with other fixtures.

6/7 CHANNEL DMX OPERATION

The 6-channel DMX mode provides position control of all effects plus speed
control of the moving mirror. The optional 7-channel mode adds speed control of
the color and gobo wheels.

Lamp power Lamp power can be switched on and off from the controller. When set up for 6- or

7-channel DMX operation, the lamp remains off until a lamp-on command is sent.

Note: A peak of electric current many times the operating current is drawn briefly
when striking a lamp. Striking many discharge lamps at once may cause a voltage
drop that prevents lamps from striking or trips circuit breakers. When striking
multiple fixtures, space lamp-on commands at 5 second intervals.

A hot lamp must be allowed to cool for several minutes before it can be turned back
on. To prevent accidental lamp-off commands, a lamp-off can be executed only
when channel 2 and 3 are set to full.

If a hot lamp does not strike, send the lamp-off command and wait several minutes
before trying again.

Reset All effects can be reset to their index positions from the controller. The reset

command must be sent for 5 seconds before it takes effect.

Shutter The shutter opens, closes, and strobes at variable rates from 1.5 to 13.5 Hz.

Stand-alone When stand-alone with music or auto trigger is selected on channel 1, the mirror

moves to random positions using the selected trigger. The color and gobo wheels
can be controlled normally, or, by setting their control channels to full, they can be
set to operate in stand-alone mode as well.

Colors The color wheel provides 15 full-color filters, 2 split-color filters, and an open

position. The wheel may be positioned between 2 positions for additional split­color effects. Movement speed can be controlled on channel 7, if enabled.

For stand-alone color action, set channel 2 to a value from 210 to 255 and set
channel 1 to stand-alone with music or auto trigger.

Gobos The gobo wheel provides 19 gobos and an open position. Movement speed can be

controlled on channel 7, if enabled.

For stand-alone gobo action, set channel 3 to a value from 240 to 255 and set
channel 1 to stand-alone with music or auto trigger.

Pan and tilt The mirror pans 230° and tilts 76.5°. Movement speed is controlled on channel 6,

allowing you to program fades on controllers without cross-fader. If your controller
has cross-faders, and you use them, set channel 6 to the “tracking” speed for best
results.

DMX operation

15

To select DMX mode

1 Disconnect the fixture from power.

2 To select 1-channel DMX mode, set DIP-switch pin 11 to ON.

3To select 6-channel DMX mode, set DIP-switch pin 11 to OFF. Verify that the 6/7

ch. jumper is set for 6 channels. This is the factory configuration. See “Setting

the 6/7-ch. DMX jumper” on page 21.

4 To select 7-channel DMX mode, set DIP-switch pin 11 to OFF. Set the 6/7 ch.

jumper for 7 channels as described on page 21.

Set DIP-switch pin 10 to OFF.

DMX ADDRESS

The DMX address, also known as the start channel, is the first channel used to
receive instructions from the controller. It is set using the DIP-switch.

For independent control, each fixture must be assigned its own address and non­overlapping control channels. Two MX-4s may share the same address only if they
are to respond identically: they will receive the same instructions and individual
control will not be possible.

Pin 12 is reserved for future use and currently has no function.

To set the DMX address

1Select a DMX mode as described above.

2Select a DMX address for the fixture on your controller.

3 Look up the DIP-switch setting for the address in Table 5.

4 Set pins 1 through 9 to the ON (1) or OFF (0) position as listed in the table.

COMPATIBLE LAMPS

The MX-4 uses the Philips CDM-SA/T (short-arc, tubular) 150W discharge lamp.
If desired, the GE Arcstream 150 may be substituted. Installing any other lamp may
damage the fixture.

To replace the lamp

WARNING! Wear safety glasses and allow the lamp to cool for at least 5

minutes before removing the lamp.

1Disconnect the fixture from power and allow it to cool.

2Remove 2 screws from the lamp-socket assembly with a Pozidriv #2

screwdriver. Remove the lamp assembly.

3Remove the old lamp from the socket.

4Holding the new lamp by its base (do not touch the glass), insert the lamp pins

squarely into the socket.

5 If your fingers touched the glass bulb, clean it with a clean, lint-free cloth

wetted with alcohol.

6Insert the lamp assembly carefully so that the lamp wires are clear of the fan.

Replace the screws.

To align the lamp

Realignment when changing the lamp may improve performance.

1Strike the lamp and shine the light on a flat surface.

2 Center the hot-spot (the brightest part of the beam) horizontally with small

turns of the top-left adjustment screw using a 3 mm Allen wrench.

3Center the hot-spot vertically with the bottom adjustment screw.

4If there is no hot-spot, adjust the reflector until the light is even.

18

Lamp

To orient the Arcstream lamp for maximum life

If using the GE Arcstream lamp, maximum lamp life will be achieved by installing
the lamp so that the arc is parallel with the ground.

This is the case in most installations. If the fixture is installed sideways, however, as

shown to the right, below, the arc will be vertical. Turn the lamp socket 90° to
achieve the ideal burning position.

1 Disconnect the fixture from power and allow it to cool.

2Remove 2 screws from the lamp-socket assembly with a Pozidriv #2

screwdriver. Remove the lamp assembly.

3Remove 2 screws from the lamp socket with a Pozidriv #1 screwdriver.

4 Turn the socket 90°, as shown below, in the direction that results in the least

amount of twist in the wires. Tuck the lamp wires into the notches in the socket

and replace the screws.

5Insert the lamp assembly carefully so that the lamp wires are clear of the fan

and replace the access-plate screws.

6Align the lamp as described above.

ASIC SERVICE

The MX-4 requires simple routine maintenance. The maintenance schedule
depends heavily on the operating environment; please consult a Martin service
technician for recommendations.

Any service procedure not described here should be referred to a qualified
technician.

Important! Excessive dust, grease, and smoke fluid buildup degrades

performance and causes overheating and damage to the fixture
that is not covered by the warranty.

Warning! Disconnect the fixture from AC power before removing any

cover.

CLEANING

To clean optical components

Use care when cleaning optical components. The surface of the color filters is
fragile and small scratches may be visible.

1Disconnect the fixture from AC power and allow the components to cool

completely.

2Remove the top cover bolts with a 4 mm Allen wrench and lift off the cover.

3Blow or vacuum away loose dust. Remove residues from lenses and filters with

a soft cloth or cotton swabs wetted with isopropyl alcohol. Regular glass

cleaner may also be used, but no residues may remain.

4Rinse with distilled water. Mixing the water with a small amount of wetting

agent such as Kodak Photoflo will help prevent streaking and spotting.

5Dry with a clean, soft and lint-free cloth or blow dry with compressed air.

6Replace the top cover.

Basic service

To clean the fan and air vents

To mai nta in ad equ ate c oo l ing , dus t mu s t be c le aned from t he fan and a ir ven ts
periodically.

1 Remove the data and power cables and stand the fixture on end.

2Remove dust and dirt from the fan blades and vent grills using a soft brush,

cotton swab, vacuum, or compressed air.

REPLACING FUSES

The MX-4 has 2 fuses. The main fuse holder is built in to the mains input socket.
The secondary fuse is located on the printed circuit board.

Warning! Never replace fuses with ones of a different rating!

To replace the main fuse

1Unplug the mains cable from the input socket. Pry open the fuse holder and

remove the fuse.

2Replace the fuse with one of the same type. The fuse rating is listed on serial

number label.

To replace the secondary fuse

1Disconnect the fixture from AC power. Remove the top cover bolts with a 4 mm

Allen wrench and lift off the cover.

2The fuse is located right behind the data input connector. Pry out the defective

fuse and replace it with one of the same rating.

3Replace the cover before applying power.

SETTING THE 6/7-CH. DMX JUMPER

1Disconnect the fixture from power.

2Remove the top cover. Locate PL 118 on the printed circuit board, next to DIP-

switch pin 12.

3Using a pair of tweezers or similar tool, place the jumper on 1 of the 2 pins, or

remove it completely, for 6-channel DMX operation. Place the jumper on both

pins to enable 7-channel DMX operation.

4 Replace the top cover before applying power.
