NTRODUCTION 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.
U N P A C K I N G The packing material is carefully designed to protect the fixture during shipment - always use it to transport the fixture. The Acrobat comes with: • mounting bracket • 1.5-meter, 3-wire IEC power cable •...
AMP INSTALLATION 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.
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.
NSTALLATION 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.

C O N N E C T I O N S The Acrobat’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.
A termination plug is simply an XLR connector with a 120 ohm, 0.25 W resistor soldered across pins 2 and 3. Male Female Termination Plug Termination Plug Male XLR Female XLR P/N 91613017 P/N 91613018 Acrobat user manual Data connection...
F U L L D M X O P E R A T I O N 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.
