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. Utilizing 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.

System Acoustic Design Considerations Direct radiator acoustic systems can offer great vocal band clarity but dont 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.
Installation Precautions This document details general mounting practices appropriate to the entertainment industry, as they would apply to the mounting of ElectroVoice Sx600 loudspeaker systems. It is intended to familiarize the reader with mounting hardware and techniques for suspending Sx600 loudspeaker systems overhead. Only persons with the knowledge of proper hardware and safe mounting techniques should attempt to suspend any sound systems overhead.
Pole Mounting Follow the pole manufacturers 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.
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.

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 (+).
Selecting Wattage Taps The Sx600 is intended to be a high level speaker, so the transformer taps are set up to produce a full 600 watts at each of the 4 voltages listed. If necessary, the wattage may be halved by selecting the next HIGHER voltage tap. NEVER select a tap for a LOWER voltage! (i.e; Do not use a 70 volt tap in a 100 volt system, etc.) The Sx600PIX is shipped from the factory pre-wired for 600 watt operation on standard 70 volt lines.
Step 5: System Adjustment and Acoustic Tuning The Sx600 MUST BE HI-PASSED at 90Hz using a minimum slope of 12dB/octave with a Q of 1.6. (Easily obtainable on the Electro-Voice Dx38 Digital Loudspeaker Controller) If analog filtering is used, a 70Hz high-pass filter of at least 12dB/octave slope and low frequency EQ of NO MORE THAN 3dB boost centered at 90 or 100Hz not to exceed one octave wide is acceptable.
System shuts down when driven hard. 1.) Insufficient amplifier power. Amplifier goes into protect mode due to overcurrent or thermal stress. Switch to a larger amplifier. 2.) Line impedance too low. (PI models in particular) Some amplifiers will not drive a 2 ohm load at full power, especially if both channels are loaded to 2 ohms. (A pair of Sx600PI systems on the same line is a 2 ohm load.
