AMP 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.
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.
