Product Description
The Sx600 Series is a remarkably flexible indoor/outdoor speaker
system designed to produce high-fidelity high-level audio in distributed
applications such as stadiums, racetracks, amusement parks,
fairgrounds, etc. tilizing a 65° x 65° high frequency horn and a unique
2-element vertical midbass array, Sx600 gives you the clarity of a direct
radiator with the high SPL and directivity of a properly designed horn
system, especially in the important vertical plane. While intended
primarily for vocal applications, the Sx600 accurately reproduces music if
heavy bass is not required.
Important Features
The Sx600 is available as either a conventional 4 ohm low impedance
system, the Sx600PI, or as a constant voltage system, the Sx600PIX.
The PIX version features a 100% duty cycle rated 600 watt full isolation
line transformer for operation with 70volt, 100volt, 140volt, or 200volt
distributed systems.
The Sx600 comes with an all-new Super Strong Arm Mount, called the
SuperSAMTM. This exclusive 2-part EV mounting system allows the
installer to pre-set the exact down angle on the ground, fasten the
separate mounting bracket by itself, and then mount the speaker to the
bracket quickly and easily with a single bolt, setting the pan angle
anywhere within a 180° arc in the process.
The three-layer stainless steel grill design is an acoustically transparent
yet effective barrier to both condensation and heavy rain. The light-
weight polypropylene enclosure has strategically placed internal
passages to conduct moisture that may accumulate internally out to the
side channels where it drains away.

System Acoustic Design
Considerations
Direct radiator acoustic systems can offer great vocal band clarity but
dont usually offer the efficiency and directivity of horn loaded systems.
Horn loaded systems, if the overall dimensions are large enough, can
offer great directivity control, but typical multi-way horn designs,
particularly high Q co-axial designs, are also naturally resonant.
Resonant systems suffer from poor time domain response and, as a
consequence, can have poor intelligibility. The EV solution is to combine
a two element critically spaced midbass line array with ultra-efficient
neodymium magnetics. This produces the high SPL levels and vertical
directivity of a properly horn loaded low/mid section while maintaining the
clear vocal reproduction of a well damped direct radiator system. The
Electro-Voice ND12A neodymium midbass driver developed for X-Array
has been optimized for ultra high level, high intelligibility 300Hz to 2kHz
response. The ND12A incorporates EVs Ring Mode Decoupling (RMD)
technology to dampen mechanical domain resonances that color vocal
fundamentals in normal direct radiator systems. RMD, found in most EV
drivers, ensures level independent tonal response and produces a level
of intelligibility unique to EV systems. The second 12 inch driver, a
specially modified DL series, works with its own crossover section and
critical spacing to the ND12A to greatly improve midband vertical
directivity and system output below 300Hz. The result is clear, clean
vocals, with the SPL capabilities required for large spaces.
The SX600 also features EVs DH2T medium format compression driver
coupled to our unique Varipath constant directivity high frequency horn.
The HF horn pattern is optimized to a 65° horizontal by 65° vertical
included angle to produce both long throw and wide front to back
audience coverage. The high power handling and low distortion
performance of the DH2T assures excellent vocal articulation with
extended high frequency coverage to beyond 16kHz.
