1 INTRODUCTION Thank you for selecting the Martin Acrobat. The Acrobat is an automated disco lighting fixture that provides strobe effects, continuous electronic dimming, 18 color/gobo effects, a revolving mirror drum with variable swivel angle, adjustable focus, and multiple control options. ACROBAT SAFETY INFORMATION Warning! This product is not for household use. It presents risks of lethal or severe injury due to fire and heat, electric shock, and falls.
To protect yourself and others from burns and fi re • Never attempt to bypass the thermostatic switch or fuses. Always replace defective fuses with ones of the specified type and rating. • Keep all combustible materials (for example fabric, wood, paper) at least 0.1 meters (4 inches) away from the fixture. Keep flammable materials well away from the fixture. • Do not illuminate surfaces within 0.3 meters (12 inches) of the fixture. • Provide a minimum clearance of 0.
2 LAMP REPLACEMENT The Acrobat comes from the factory with a Philips 500 hour lamp installed. This a 24V, 250W ELC halogen lamp. A high-output 50 hour lamp from Osram is also available. Installing any other lamp may damage the fixture! Lamp life can be extended beyond the stated average hours by reducing the lamp voltage slightly using DIP-switch pin 12. Set pin 12 to ON for longer lamp life, or OFF for maximum brightness.
3 AC POWER CONNECTION The Acrobat’s operating voltage is printed on the serial number label near the AC input. Verify that the operating voltage closely matches the AC supply voltage before applying power. Contact your Martin dealer if the operating voltage differs from the supply voltage by more than five percent. To install a plug on the mai ns lead The fixture’s mains lead may require a grounding-type cord cap that fits your power distribution cable or outlet.
4 INSTALLATION The Acrobat can be permanently installed or hung with a clamp (not included), or it can be placed on the floor as described below. For maximum lamp life, do not place the fixture directly on or beside a speaker cabinet or other source of strong vibrations. Once the Acrobat is installed and connected, the focus may be adjusted by loosening and sliding the focus adjustment knob. Warning! Block access below the work area before proceeding.
recommended by the clamp manufacturer, through the clamp hole in the mounting bracket. 3 If permanently installing the fixture, verify that the hardware (not included) and mounting surface can bear at least 10 times the fixture’s weight. The four 6 mm holes and the clamp hole in the mounting bracket may be used for attachment. 4 Working from a stable platform, clamp or fasten the fixture to the structure.
5 DATA CONNECTION This section describes how to connect fixtures to a controller. RECOMMENDED CABLE 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 Acrobat’s XLR data sockets are wired with pin 1 to ground, pin 2 to signal (cold), and pin 3 to signal + (hot).
To connect the data link 1 Connect a data cable to the controller’s output. If controller has a 5-pin output, use a 5-pin male to 3-pin female adaptor cable (P/N 11820005). 2 Lead the data cable from the controller to the first fixture. Plug the cable into the fixture’s data input. 3 Connect the output of the fixture closest to the controller to the input of the next fixture. If connecting two fixtures with reversed polarity on pins 2 and 3, insert a phase-reversing cable between the two fixtures.
6 STAND-ALONE OPERATION The Acrobat may be operated without a controller in stand-alone mode. It may be operated as a single unit or together with other Acrobats in “master/slave” configuration. Several options are available to modify stand-alone operation. These options are selected using the DIP-switch as described below. Important! The Acrobat transmits a signal when DIP-switch pins 2 and 10 are set to ON.
To set the master Important! Set only 1 fixture as master (DIP-switch pin 2 and 10 ON). 1 Set DIP-switch pins 2 and 10 to ON. 1 2 2 Set DIP-switch pins 3, 5, 6, 7, 8, 9, and 11 to OFF. 3 Select options with DIP-switch pins 1, 4, and 12. To set a sl ave 1 Set DIP-switch 10 to ON. 2 Set pins 1, 2, 3, 4, 5 and 11 to OFF. 3 Select options with DIP-switch pins 6, 7, 8, 9, and 12. STAND-ALONE SETTINGS DIP-switch pins 1-9 enable stand-alone options only when pin 10 is ON.
7 MC-1 OPERATION All new Acrobats and older Acrobats with CPU firmware v 1.4 or higher are fully compatible with the Martin MC-1 Controller. See the MC-1 user manual for additional information. MC-1 SETTINGS DIP-switch pin 10 must be set to OFF to enable MC-1 mode operation. Changes to the setting take effect after the fixture has been turned off and on. DIP-switch pins 6, 7, 8, and 9 select several control options that can be combined to achieve powerful effects quickly and easily.
DMX OPERATION 8 DMX MODES The Acrobat has 3 DMX modes to choose from: a 1-channel mode that provides control of the built-in stand-alone features, a 6-channel mode that provides position control of all effects plus speed control of the drum swivel movement, and an “extended” 7-channel mode that in addition provides speed control of the effect wheel. To select DMX mode 1 Disconnect the fixture from power. Set DIP-switch pin 10 to OFF. 2 To select 1-channel DMX mode, set DIP-switch pin 11 to ON.
3 Set pins 1 through 9 to the ON (1) or OFF (0) position as listed in the table. Find the address in the table below. Read the settings for pins 1 - 5 to the left and read the settings for pins 6 - 9 above the address. “0” means OFF and “1” means ON. Pin 10 is always OFF for DMX operation.
1-CHANNEL DMX OPERATION The functions shown in the following table are available in 1-channel mode. When a “stand-alone” function is selected, the fixture steps through a routine using a built-in microphone to trigger the action to the beat of the music. Note that multiple fixtures cannot be synchronized in this mode.
BASIC 9 SERVICE To set the 6/7-ch. DMX jumper 1 Disconnect the fixture from power. 2 Remove the effects section cover. It is secured by 5 Torx-20 screws: 3 on the side with print and 2 on the other side. 3 Locate PL 118 on the printed circuit board, next to DIP-switch pin 12. 4 Using 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.
10 TROUBLESHOOTING Problem Probable cause(s) No power to fixture. Fixture is completely dead. Fixture resets correctly but does not respond to controller. Intermittent flicker or strange behavior. Effect fails to reset correctly. No light. Lamp cuts out intermittently or burns out too quickly. Acrobat user manual Remedy Check that power is switched on and cables are plugged in. Primary fuse blown. Replace fuse. Secondary fuse blown. Contact Martin technician for service.
