[. . . ] It allows the installer to simply snap the speaker onto the bracket, then tighten it to the desired position. For array mounting, there is an optional array bracket kit available which allows multiple units to be mounted together for a variety of configurations. Zx1i uses a special circuit that when in transformer mode the network re-configures itself to a current actuated Hi-Pass filter at the transformer primary. [. . . ] Zx1i uses a special circuit that when in transformer mode the network re-configures itself to a current actuated Hi-Pass filter at the transformer primary. It gently rolls off the lowest frequencies to maintain a safe load on the amplifier without affecting 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. Two coverage patterns are available; 90° x 50° coverage for longer throw and cluster applications, 100° x 100° coverage for broad even dispersion needed in 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 support bracket shall be low profile and integral with the enclosure. The bracket shall allow for a quick snap fit mounting of the speaker enclosure for placement before securing. The speaker terminals shall include a 4 pin removable phoenix style connector to allow for signal pass through. The system shall be weather resistant to MIL Spec 810 and IEC 529 test conditions. The loudspeaker shall be available with a 100w transformer for 70 or 100v operation. The speaker shall have ASCTM for protection against transformer saturation overload. There shall also be an 8 ohm bypass position on the wattage selector switch to enable 8 ohm operation from these models. The loudspeaker system shall meet the following performance criteria: Power handling, 200-Watts long term program using IEC268-5 shaped pink noise; Frequency response, 48 Hz ­ 20 kHz (-10 dB from rated sensitivity); Pressure sensitivity, 94 dB at one watt, 60 Hz ­ 20 kHz at one meter; Impedance, 8 ohms nominal, 6 ohms minimum.

The enclosure shall be 17. 75" (451mm) high, 11. 12" (282mm) wide, 10. 35" (263mm) deep. [. . . ]
