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

SuperSAM. 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.

Installation Precautions

This document details general mounting practices appropriate to the

entertainment industry, as they would apply to the mounting of Electro-

Voice Sx600 loudspeaker systems. It is intended to familiarize the reader

with mounting hardware and techniques for suspending Sx600 loud-

speaker systems overhead. Only persons with the knowledge of proper

hardware and safe mounting techniques should attempt to suspend any

sound systems overhead. Prior to suspending any Electro-Voice Sx600

loudspeaker systems overhead, it is essential that the user be familiar

with the strength ratings, mounting techniques and special safety consid-

erations outlined in this manual. The mounting techniques and practices

recommended in this manual are, of necessity, in general terms to

accommodate the many variations in mounting configurations. As such,

the user is expressly responsible for the safety of all specific Sx600

loudspeaker mounting configurations as implemented in practice.

The Sx600 SuperSAMTM Mounting System is intented to support the

Sx600 Speaker System only. Do not use it for any other purpose. Never

set anything on, or hang anything from, the Sx600 SuperSAMTM when

using it for the Sx600 Speaker System.

Installation Notes

The Sx600PI weighs in at 63 lb (28.6 kg.) and the Sx600PIX at 81 lb

(36.8 kg).

It is the installers responsibility to insure that the mounting

surface is stable and sufficiently strong to support the

weight of the unit(s) being mounted.

The SuperSAM is made of tough 6061T6 aluminum, and the actual

mounting bracket is stainless steel. DO NOT WELD. Consult and follow

all applicable codes and procedures. se only ½ inch diameter

mounting bolts, 4 per bracket minimum. (all 6 is recommended) When

mounting outdoors, remember to allow for wind, snow and ice load. Do

not locate the Sx600 where it may be subjected to water or snow run-off

from roofs, gutters, etc. Never mount an Sx600 on its side.

Block Wall Mounting

Do not attempt to mount an Sx600 to a block or brick wall without

through-bolts and large, heavy steel backing plates on both sides of the

wall. On poured concrete walls use deep ½ inch diameter anchors that

cannot be pulled out once set. se all 6 mounting holes.

Pole Mounting

Follow the pole manufacturers recommendations when mounting to a

pole. On wooden poles, make sure there is no rot or other deterioration.

Through-bolts with backing plates are highly recommended. Lag bolts

should only be used in conjunction with straps.

Stud Wall Mounting

First determine whether the structural members in the wall can withstand

not only the weight of the Sx600, but also the side-to-side stresses of

heavy cross-winds. Reinforce both sides of the wall with heavy plates, ¾

inch marine plywood minimum, and use through bolts. Never rely on lag

bolts alone. Additional side-to-side support may be had by attaching

simple steel outriggers (not included) from the SuperSAM pivot bolt to

the next stud on either side of the mounting bracket. Never mount to a

wall containing plaster or drywall without backing plates.

I-Beam Mounting

Because of the vast number of sizes and conditions of their use, consult

a licensed structural engineer for the approved method of attaching an

Sx600 to any particular I-Beam or other structural component.

Mounting Surface Reinforcement

If in doubt: Make It Stronger. Strong side winds will exert tremendous

side leverage along the axis of the mounting bolts sufficient to crush

some surfaces. A large backing plate and/or steel outriggers attached

from the pivot bolt to the wall 16" to 24" either side of center makes a

simple and effective reinforcement in most situations.

Installation Procedure

Step 1: Selection and Preparation of the

Mounting Surface

Surface must be clean and smooth. It must also be a material that is not

easily crushed. While the SuperSam distributes weight evenly over a

relatively large area, strong winds against the side of the Sx600 will exert

significant crowbar-like leverage between the bolts and the side corner

edges of the bracket. For this reason, surfaces of plaster, drywall, soft

wood, cinder block, ceramic, glass or other brittle, crushable materials

must have a large heavy backing plate to prevent the Sx600 from

loosening itself by crushing its mounting surface.

Step 2: Mounting the SuperSAM Bracket

If bolts are to be used, determine the exact location desired for the holes

on the mounting surface. se a center punch to mark the center of each

hole to be drilled and minimize hole drift. Drill holes and DE-BURR. The

bracket M ST sit perfectly flat against the mounting surface. Mount the

bracket using ½ bolts, washers, lock washers and nuts, and tighten

securely. Stainless Steel hardware is recommended.

Step 3: Mounting the Speaker and Aligning

Pre-set the down angle of the speaker (as pre-determined by EASE) by

inserting the 5/16 Stainless Steel bolt through the appropriate holes (See

Figure 5). Tighten it and the ½ pivot bolt securely. (If aiming visually,

tighten bolts finger-tight only until aiming is finalized.) Place the long ½

bolt and washer through the appropriate hole in the mounting bar. Use

the hole nearest the speaker for down-angles of less than 40 degrees and

the farthest hole for angles greater than 40 degrees. Set the speaker on

the already mounted bracket end bar, dropping the ½ pivot bolt through

the hole near the end of the bar. (The second hole is provided as a

convenience for certain close in situations.) Install the flat washer, lock

washer and nut and tighten just enough to pull both bars together.

Determine pan angle by sighting along center groove of enclosure. (Either

top or bottom) Securely tighten pivot bolt to lock in place. Visually check

down angle. Too high an angle will result in poor intelligibility in the near-

field; a too-low angle will cause poor intelligibility far-field and a hot spot

close in. If necessary, re-set the down-angle as follows: Loosen the ½

bolt on the adjusting bracket and remove the 5/16 bolt. Tilt the speaker

to the desired angle and re-insert the 5/16 bolt in the appropriate hole.

Re-tighten all hardware.

Step 4: Completing the Electrical Connections

Trim the SJO cord to a neat length while allowing enough slack for future

aiming adjustments or service. Make electrical connections per all

applicable codes in a weather-tight box and secure the SJO cord through

a weather-tight gland nut. Observe color code for proper polarity: Black

wire from speaker is audio (-), white wire is audio (+).

sing the PIX (Constant Voltage Version)

Constant Voltage Design Considerations

One of the major expenses of any large sound system up-grade is the

cost of running new wiring. For this reason, the Sx600PIX transformer

has taps for use on lines as high as 200volts, which is easily delivered by

an Electro-Voice CPS-4 amplifier in bridge mode. Keeping the current

draw the same, changing from 70volts to 200volts means you can now

pull approximately 3 times the wattage from the same wiring! In new

installations, the higher voltages mean less line loss on long runs, less

current and lighter gauge wire. Always check and comply with all

applicable codes.
