The Electro-Voice® ZX1i is the new standard of no compromise audio performance
and versatility in an easy to install, compact sound reinforcement package.
The high-tech enclosure uses injection-molded high-impact polypropylene to make
the ZX1i extremely durable. The enclosure geometry has been engineered to
provide maximum rigidity and acoustic performance. The velocity compensated
port design overcomes the limitation of many small cabinet loudspeakers and
enables exceptional low-frequency response without vent noise.
ZX1i installation is incredibly simple with the included QuickSAM
TM
mounting sys-
tem. The QuickSAM
TM
is a unique, integrated mounting bracket which is virtually
foolproof. 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. 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 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.
The ZX1i’s long excursion, high output 8" woofer with a weatherized treated cone
delivers smooth low-frequency performance with exceptional reliability. A sophis-
ticated crossover network integrates it with the DH2005, a 1-inch voice coil true
compression driver maximum output with extended frequency response. Full-
bandwidth overload protection is provided for reliable, long term operation without
audible effect.
