Introduction Thank you and congratulations on your purchase of QSC’s ISIS multipurpose loudspeakers. These products represent the state-ofthe-art in lightweight SR (sound reinforcement) loudspeaker systems. To get the most from your investment, we encourage you to review this manual carefully.
Coverage Angles 102M/122M/152M- These models are equipped with 60° conical waveguides. HF coverage remains constant regardless of cabinet orientation. 102W- Before mounting the loudspeaker, determine the mounting orientation and desired coverage angles. As supplied from the factory, the loudspeaker’s coverage angles are 150° (horizontal) x 50° (vertical) with the cabinet oriented vertically. The waveguide can be rotated to interchange the coverage angles.
Select the Desired Crossover Mode All models are equipped with a Crossover Mode switch. Before using, set the Crossover Mode switch to the desired position using a flat-tip screwdriver. The switch has a slotted shaft; insert the screwdriver tip into the slot and turn the shaft so the slot points to the desired mode. Do not change switch positions with power applied. FULL RANGE: This setting uses the internal crossover network. Connect the full-range input signal to Speakon pins 1+ and 1-.
Recommended Fastener Torque Fly track to cabinet-4.52 Nm (40 in-lb) Pole cup to cabinet- 1.92 Nm (17 in-lb) Waveguide to cabinet- 1.92 Nm (17 in-lb) LF driver to cabinet- 1.92 Nm (17 in-lb) Grill to cabinet-1.01 Nm (9 in-lb) Connector plate to cabinet-1.01 Nm (9 in-lb) EN All fasteners should be checked for tightness before loudspeaker use. If any fastener is loose or is removed for any reason, ensure it is installed using a torque-limiting tool to avoid cabinet damage.
