[. . . ] the higher (vocal) frequencies and the program continues without interruption. Low frequency current is limited through the transformer eliminating low frequency saturation. Automatic Saturation Compensation allows many speakers to be run on a distributed line with a 50Hz Hi-Pass filter before the amplifier, regardless of the number of speakers on the same line (the number of tapped watts cannot exceed the amplifier rating). With the same 50Hz Hi-Pass, 10 speakers on transformers will have the same full sound as a single speaker at 8 ohms. ° x 50° coverage for longer throw and cluster applications, 100° ° many distributed audio applications. An added benefit is horn rotation, allowing the ZX1i to be oriented either horizontally or vertically for complete coverage flexibility. The ZX1i molded polymer enclosure is inherently water resistant. The addition of a multilayer grille with hydrophobic cloth and weatherized components enable the ZX1i to perform under many environmental conditions. An optional weatherized input panel cover with a gland nut is available for additional protection. sophisticated crossover network integrates it with the DH2005, a 1-inch voice coil true compression driver maximum output with extended frequency response. Fullbandwidth overload protection is provided for reliable, long term operation without audible effect. Tc F . To rotate the horn follow the steps below: 1. Remove the logo badge to expose grille mounting screws. Remove the grille assembly ­ see illustration Remove the screws holding the horn assembly in place. ­ see illustration Rotate the horn assembly 90°. Secure the horn assembly back to the baffle with the horn mounting screws. Secure the grille assembly to the baffle with grille mounting screws. Secure the logo badge back onto the grille. 90° x 50° Horn Horn Mount Screws Grille Assembly Logo Badge Grille Mount Screws Enclosure Figure 8: Horn Rotation (90° x 50° Models Only) Electro-Voice® Zx1i Owner's Manual 7 Step 4: Attach the Speaker to the QuickSAMTM Bracket After mounting the QuickSAMTM bracket (from Step 1) to the desired surface, attach the speaker to the QuickSAMTM bracket by inserting the QuickSAMTM into slot on the side of the speaker until it "clicks" in place. Using the provided mounting tool, tighten the two socket head bolts A and B enough to allow aiming, as shown in Figure 9. After selecting the proper horizontal angle, secure the sweep axis as shown by tightening bolt A. Next, select the proper vertical angle and secure the rotation axis by tightening bolt B. To tighten the recessed bolt B, insert mounting tool through hole on the side of the speaker. WARNING: Bolt "B" is what secures the speaker to the QuickSAMTM Bracket. [. . . ] Verify that you have connected the correct wire pairs to the amplifier. Play something at low level through the amplifier (for example, from a CD player or tuner). Connect the test speaker in parallel with the malfunctioning line. If the sound level has gone or is very weak, the line has a short in it (possibly a severe scrape, pinch, or staple puncture).
