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.
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. EN NL4 to NL4 Wiring (two- and four-conductor cables) Two- or four-conductor cable may be used for Speakon to Speakon connections.
Mounting Stand Alone Mounting If using the loudspeaker only, it can be set on any appropriate surface. The cabinet will lean back at a slight angle when set on a flat surface. Install the four self-adhesive rubber feet on the cabinet bottom to stabilize the loudspeaker and to help prevent it from moving due to cabinet vibration at high output levels. On the back of the loudspeaker, near the bottom, is a safety cable attachment point.
Optional I-YM8 Accessory Kit The I-YM8 Accessory Kit includes a yoke mount bracket, two loudspeaker retaining knobs, two swivel feet with retaining knobs, mic stand adapter, pole cup and retaining knob. The I-YM8 Accessory Kit enables you to mount the loudspeaker to most any surface using the yoke mount bracket, or use as a floor monitor by attaching the two swivel feet. If wall mounting the yoke, we recommend removing the swivel feet.

Painting the I-82H Loudspeaker The loudspeaker enclosure, grill, and mount can be painted to match any decor, provided the following precautions are observed. The cabinet is made of high impact polystyrene which requires controlled painting procedures in order to obtain good results. Use a paint “system” designed for high impact polystyrene from any reputable paint supplier. 1- Remove the grill. 2- If painting mount and loudspeaker as a unit: Attach the I-YM8. 3- Mask the loudspeaker’s input connector.
