Protection from injury
Do not look continuously at LEDs from a distance of less than
8.3 meters (27 ft. 3 inches) from the front surface of the fixture
without protective eyewear such as shade 4-5 welding goggles.
At less than this distance, the LED emission can cause eye
injury or irritation. At distances of 8.3 meters (27 ft. 3 inches) and
above, light output is harmless to the naked eye provided that
the eye’s natural aversion response is not overcome.
Do not look at LEDs with magnifiers, telescopes, binoculars or
similar optical instruments that may concentrate the light output.
Ensure that persons are not looking at the LEDs from within 8.3
meters (27 ft. 3 inches) when the product lights up suddenly.
This can happen when power is applied, when the product
receives a DMX signal, or when certain control menu items are
selected.
To minimize the risk of eye irritation or injury, disconnect the
fixture from power at all times when the fixture is not in use, and
provide well-lit conditions to reduce the pupil diameter of anyone
working on or near the fixture.
Fasten the fixture securely to a fixed surface or structure when
in use. The fixture is not portable when installed.
Ensure that any supporting structure and/or hardware used can
hold at least 10 times the weight of all the devices they support.
If suspending from a rigging structure, fasten the fixture to a
rigging clamp. Do not use safety cables as the primary means of
support.
If the fixture is installed in a location where it may cause injury or
damage if it falls, install a secondary attachment such as a
safety cable that is approved by an official body such as TÜV as
a safety attachment for the weight that it secures. The safety
cable must comply with EN 60598-2-17 Section 17.6.6 and be
capable of bearing a static suspended load that is ten times the
weight of the fixture and all installed accessories.

Introduction
The MH-2 Wash is an extremely small, fast and powerful LED moving beam
and wash effect incorporating seven 10 W long-life LEDs. It provides a 20°
beam angle, smooth electronic dimming, as well as strobe effects. The device
is extremely rugged, lightweight and compact, and is ideal for mobile DJ’s,
touring or small fixed installations.
The fixture can be controlled using any DMX-compliant controller, or operate
as a standalone device, running one of four pre-programmed shows, with the
option of sound-activated scene triggering.
The fixture is supplied with this user manual and a 1.5 m (5 ft) power cable
(local power plug not included).
Before using the product for the first time
1. Read Safety information on page 5 before installing, powering, operating
or servicing the fixture.
2. Unpack and ensure that there is no transportation damage before using
the fixture. Never attempt to operate a damaged fixture.
3. If the fixture is not going to be hard-wired to a mains supply, attach a local
power plug (not supplied) to the end of the supplied power cable.
4. Before operating, ensure that the voltage and frequency of the power
supply match the power requirements of the fixture. (See Specifications on
page 32.)
5. Check the Martin Professional website at www.martin.com for the most
recent user documentation and technical information about the fixture.
RUSH by Martin user manual revisions are identified by the revision letter
at the bottom of the inside cover.
Note that whenever AC power is applied to the fixture, it will always reset all
effects and functions to their home positions. The fixture head will move. This
process usually takes around 20 seconds.

Physical installation
The fixture is designed for indoor use only and must be used in a dry location
with adequate ventilation. Always ensure that none of the fixture’s ventilation
slots are blocked and always ensure that the product is firmly affixed to avoid
vibration during operation.
Fastening the fixture to a flat surface
The fixture can be fastened to a hard fixed flat surface that is oriented at any
angle. Ensure that the surface can support at least 10 times the weight of all
fixtures and equipment to be installed on it.
Fasten the fixture securely. Do not stand it on a surface or leave it where it can
be moved or fall over. Attach a securely anchored safety cable to the fixture if
it is installed in any location where it may fall and cause injury or damage if the
primary attachment fails.
Mounting the fixture on a truss
The fixture can be clamped to a truss or similar rigging structure in any
orientation. When clamping a fixture to a truss:
1. Check that the rigging structure can support at least 10 times the weight of
all fixtures and equipment to be installed on it.
2. Block access under the work area.
3. Rig the fixture using clamps and hardware suitable for the purpose.
Working from a stable platform, hang the fixture on the truss. Tighten the
rigging clamps and hardware.
4. Secure the fixture against clamp failure with a secondary attachment such
as an approved safety cable that is rated for the weight of the fixture.
5. Check that the head will not collide with other fixtures or objects.

RUSH MH-2 Wash user manual 11
AC power
Read Safety information on page 5 before connecting the fixture
to AC mains power.
For protection from electric shock, the fixture must be grounded
(earthed). The power distribution circuit must be equipped with a
fuse or circuit breaker and ground-fault (earth-fault) protection.
Socket outlets or external power switches used to supply the
fixture with power must be located near the fixture and easily
accessible so that the fixtures can easily be disconnected from
power.
Do not insert or remove live Neutrik PowerCon connectors to
apply or cut power, as this may cause arcing at the terminals
that will damage the connectors.
Do not use an external dimming system to supply power to the
fixture, as this may cause damage to the fixture that is not
covered by the product warranty.
Use only Neutrik PowerCon cable connectors to connect to power sockets.
Power input and throughput cables must be rated 20 A minimum, have three
conductors 1.5 mm² (16 AWG) minimum conductor size and an outer cable
diameter of 5 - 15 mm (0.2 - 0.6 in.). Cables must be hard usage type (SJT or
equivalent) and heat-resistant to 90° C (194° F) minimum. In the EU the cable
must be HAR approved or equivalent. Cables used for power throughput must
meet the same specifications as for power input cables.
The fixture can be hard-wired to a building electrical installation if you want to
install it permanently, or a power plug that is suitable for the local power outlets
can be installed on the power cable.
The fixture has an auto-ranging power supply that accepts AC mains power at
100V~240V, 50/60 Hz. Do not apply AC mains power to the fixture at any other
voltage than this.
Power can be relayed from one fixture to another device in a daisy-chain via
the white PowerCon throughput socket. Do not connect devices to power in a

RUSH MH-2 Wash user manual
12
chain that will exceed the power and current ratings of any cable or connector
used in the chain. When using:
•120 V, 60 Hz mains power, do not connect more than 3 fixtures to power in
one chain.
•230 V, 50 Hz mains power, do not connect more than 5 fixtures to power in
one chain.

Control data link
A DMX 512 data link is required in order to control the fixture via DMX. The
fixture has 3-pin and 5-pin XLR connectors for DMX data input and output.
The number of daisy-chained fixtures is limited by the number of DMX
channels required by the fixtures in relation to the maximum 512 channels
available in one DMX universe. Note that if independent control of a fixture is
required, it must have its own DMX channels. Fixtures that are required to
behave identically can share the same DMX address and channels. To add
more fixtures or groups of fixtures when the above limit is reached, add a DMX
universe and another daisy-chained link.
Tips for reliable data transmission
Use shielded twisted-pair cable designed for RS-485 devices: standard
microphone cable cannot transmit control data reliably over long runs. 24 AWG
cable is suitable for runs up to 300 meters (1000 ft.). Heavier gauge cable
and/or an amplifier is recommended for longer runs. The pin-out on all
connectors is pin 1 = shield, pin 2 = cold (-), and pin 3 = hot (+). Pins 4 and 5
in the 5-pin XLR connectors are not used in the fixture but are available for
possible additional data signals as required by the DMX512-A standard.
Standard pin-out is pin 4 = data 2 cold (-) and pin 5 = data 2 hot (+).
To split the link into branches, use a splitter, such as the Martin 4-Channel
Opto-Isolated RS-485 Splitter/Amplifier. Terminate the link by installing a
termination plug in the output socket of the last fixture. The termination plug,
which is a male XLR plug with a 120-Ohm, 0.25-Watt resistor soldered
between pins 2 and 3, “soaks up” the control signal so it does not reflect and
cause interference. If a splitter is used, terminate each branch of the link.
Connecting the data link
To connect the fixture to data:
1. Connect the DMX data output from the controller to the closest fixture’s
male XLR DMX input connector.
2. Connect the DMX output of the fixture closest to the controller to the DMX
input of the next fixture and continue connecting fixtures output to input.
Terminate the last fixture on the link with a 120-Ohm resistor.

Fixture setup
This section explains the fixture characteristics that can be set that determine
how it can be controlled and will behave. These settings are made using the
menus available from the control panel, and are retained, even when the
fixture is powered off.
Using the control menus
A map of the control menu structure can be found in Control menus on page
28.
To access the control menus, press the MENU button. Navigate the menu
structure using the ENTER, DOWN and UP buttons. Select any required menu
option using the ENTER button. To return to a higher level in the menu
structure without any change press the MENU button.
To exit the menu mode, hold and press the MENU button. (This will occur
automatically after a period where there has been no user input.)
DMX addressing
The DMX address, also known as the start channel, is the first channel used to
receive instructions from a DMX controller. The fixture can be controlled using
signals sent by a DMX controller on twelve channels. Each DMX controlled
fixture must have a DMX address set. For example, if a fixture has a DMX
address of 10, then it uses channels 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20
and 21. The following fixture in the DMX chain could then be set to a DMX
address of 22.
For independent control, each fixture must be assigned its own control
channels. Two fixtures of the same type may share the same address, if
identical behavior is desired. Address sharing can be useful for diagnostic
purposes and symmetric control, particularly when combined with the inverse
pan and tilt options.
The DMX address is configured using the DMX ADDRESS menu in the control
panel.
