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. BI-AMP: This setting bypasses the internal crossover network and connects Speakon pins 1+ and 1- to the low-frequency (LF) driver and pins 2+ and 2- to the high-frequency (HF) driver. Signal processing ahead of the amplifier is required; the HF driver can easily be damaged if full range program is applied!Use a four-wire cable and an amplifier configured to operate in bi-amp mode. BIAMP OPERATION- Signal processing ahead of the amplifier is required; the HF driver can easily be damaged if full range program is applied! FULL RANGE EN BI-AMP Make the Required Connections All models are equipped with two Neutrik NL4-series airtight Speakon connectors. The two connectors are wired in parallel, allowing for multiple cabinets to be connected in parallel by plugging one cabinet into another with a suitable cable. Bi-amp selection uses pins 1+ and 1- for the LF driver, 2+ and 2- for the HF driver. 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. Speakon plug pinouts- The Speakon plugs that are connected to the loudspeaker cabinets should conform to the pin outs shown at right. The connectors are shown from the wire-insertion end and show the inside of the disassembled Speakon plug. 5 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. Fly track hardware is safetycritical and should be carefully checked before suspending or rigging the cabinet. 6 ISIS 102M Dimensions (ISIS 102W similar) EN Specifications are subject to change without notice. 7 ISIS W-102M Dimensions (ISIS W-102W similar) EN Specifications are subject to change without notice. 8 ISIS 122M Dimensions EN Specifications are subject to change without notice. 9 ISIS W-122M Dimensions EN Specifications are subject to change without notice. 10 ISIS 152M Dimensions EN Specifications are subject to change without notice.
