I-82H Introduction

Thank you and congratulations on your purchase of the ISIS Series I-82H High Performance Portable Loudspeakers. This product represents the state-of-the-art in lightweight sound reinforcement loudspeaker systems. To get the most from your investment, we encourage you to review this manual carefully.

The I-82H loudspeaker system is a full range, high output, twoway design delivering superior sound quality and high SPL in a lightweight, attractive enclosure. Equipped with two Speakon connectors, connection is fast and reliable with parallel connection of multiple cabinets literally a snap. These loudspeakers make an excellent choice for a wide variety of applications.

Two mounting adapters are provided; a pole cup that accepts

1.375” or 1.500” (35 mm or 38 mm) pole diameters and a 5/8”-27 mic stand adapter (fits most mic and boom stand hardware). The pole cup is equipped with a retaining knob to secure the adapter to the pole. Also included are four self-adhesive rubber feet for the bottom of the enclosure.

I-YM8 Optional Yoke Mount / Floor Monitor Kit

The optional I-YM8 Accessory Kit provides a yoke mount suitable for pole mounting and a pair of swivel extension feet for use as floor or stage monitors. The included pole cup or mic stand adapter can be attached to the yoke mount using the included knob as well as standard truss clamps for additional mounting options.

Coverage Angles

Before mounting the loudspeaker, determine the mounting orientation and desired coverage angles. As supplied from the factory, the loudspeaker’s coverage angles are 90° (horizontal) x 60° (vertical) with the cabinet oriented vertically. The waveguide can be rotated to interchange the coverage angles.

Rotating the Waveguide to Alter HF Coverage Pattern

1- Remove the grill. Gently and evenly work the grill out of its retaining groove to avoid bending the grill.

2- Remove the eight waveguide retaining screws. A #2-size Phillips screwdriver is recommended.

3- Reach into the waveguide’s port and pull gently to remove the waveguide. Be careful not to damage the connections, wiring, or the gasket between the waveguide and the cabinet.

4- Rotate the horn 90° clockwise or counter clockwise and set it back in place. Make certain the wiring is not stressed or pulled loose from its connections.

5- Before reinstalling the waveguide screws, lift the assembly a small distance and make sure that the gasket is properly in place. Reposition it, if required. Set the waveguide in place and reinstall the screws. Do not overtighten.

6- Replace the grill.

Logo Badge Rotation

The logo badge on the grill screen can be removed, rotated, and reinstalled. Using your fingers, pull the logo badge straight out. Rotate to the desired position and push back into place.

Connection

The I-82H has two Speakon® NL4-type connectors wired for full range, passive operation. Connect the amplifier’s + and - outputs directly to the Speakon’s 1+ and 1- terminals.

The two connectors are wired in parallel to make parallel cabinet connection easy. Your amplifier must be able to safely power the lower impedance of parallel-connected loudspeakers.

NL4 to NL4 Wiring (two- and four-conductor cables)

Two- or four-conductor cable may be used for Speakon to Speakon connections. Four-conductor cable can be used, but the extra conductors do not carry signal.

The I-82H is not wired for biamp operation. Do not connect biamplified equipment to the I-82H.

Maintain proper speaker and amplifier connection polarity throughout the entire system. All positive-marked loudspeaker terminals should be connected to positive-marked amplifier output terminals. This will provide the best possible low-frequency output from your system.
