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 DMX and stand-alone 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 prot ect yoursel f and ot hers fr om 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.
LAMP INSTALLATION 2 The Acrobat uses a 24V, 250W ELC halogen lamp. Two models are available, an economical 300 hour lamp from Philips and a high-output 50 hour lamp from Osram. 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. Allow the lamp to cool for at least 5 minutes before packing and moving the fixture.
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 inst all a plug on t he mains 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.
DIP- SWITCH SETTINGS 5 This section describes how to select the address, when used with a controller, and how to select various options using the DIP-switch. DMX ADDRESS SELECTION When the Acrobat is used with a DMX controller, its DIP-switch must be set to a control address. The control address, also known as the start channel, is the first channel used to receive instructions from the controller.
DIP-SWITCH ADDRESS 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. Important! Pins 10 and 11 must be OFF for full DMX control. Pin 10 must be OFF and pin 11 must be ON for 1-channel DMX control.
SPECIAL SETTINGS DIP-switch pins 1 - 9 are used to select special options in stand-alone and master/slave mode. To enable these options, pin 10 must be ON. Pin 11 toggles between 1 and 6 channel DMX control. It must be OFF for master/slave operation. Lamp life can be extended by reducing the voltage slightly. Set DIP-switch pin 12 to ON for longer lamp life, or OFF for full output intensity. Note: the fixture shall be disconnected from AC power when changing DIPswitch settings.
6 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 t he dat a 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.
7 OPERATION FULL DMX OPERATION For DMX operation, connect the Acrobat to a DMX controller as described on page 12 and set the control address as described on page 9. The Acrobat automatically defaults to music-trigger stand-alone mode if there is no control signal. DMX CHANNEL DESCRIPTION See also the DMX protocol on page 18. Channel 1 controls the light intensity and the strobe rate.
If using the MC-1, select DMX channel 1. If using a DMX controller, any channel within the controller’s range may be assigned. The single-channel controllable functions are shown below.
8 SERVICE There are no user-serviceable parts inside the Acrobat. Please refer all service to a Martin distributor, dealer, or service center. To replace the main f use 1 Unplug the mains cable from the input socket. Pry open the fuse holder and remove the fuse. 2 Replace the fuse with one of the same type. The fuse rating is listed on serial number label.
9 TROUBLESHOOTING Problem Probable cause(s) Remedy No power to fixture. Check that power is switched on and cables are plugged in. Primary fuse blown. Replace fuse. Secondary fuse blown. Contact Martin technician for service. The DMX signal is not transmitted. Connect controller. Inspect connections and cables. Correct poor connections. Repair or replace damaged cables. The DMX data signal is reversed. Insert a phase-reversing cable in the link before the fixture.
