Page 7: Sonus Series Operation Manual
SONUS SERIES OPERATION MANUAL INTRODUCTION Thank you for selecting Community’s SONUS Series. SONUS is a family of affordable, linear-response loudspeakers designed for use in applications requiring controlled coverage patterns, high-impact power response, with clear and intelligible sonic output. All models are designed with portability in mind, but they are equally effective in permanent or semi- permanent installations. -

Page 14: General Description
GENERAL DESCRIPTION SONUS Series loudspeakers are designed for demanding day-to-day use in a wide range of both portable applications and fixed installations. Their high quality driver components are housed in rugged, acoustically inert enclosures fitted with convenient carrying handles, rigging fittings, and support stand receptacles. SONUS systems are characterized by a high-power, low distortion linear response that provides exceptional musicality and speech intelligibility. -
Page 15: High-Frequency Presence Switch
Because the first and second stages of Community’s DYNA-TECH circuits are not thermally sensitive, they react nearly instantaneously to protect against excessive increases in level. -
Page 16: Selectable High-Pass Output On Subwoofers
HIGH-PASS position, where the load impedance has been increased by about 50% by the subwoofer’s internal crossover circuit, thereby protecting the amplifier from premature clipping and potential failure. Community SONUS Series - Operation and Installation Manual - Page 16... -

Page 18: Cool-Coil™ Technology
This air passing through the pole vent helps to cool the magnet structure. Community has improved on this common cooling method by introducing an airflow director (US patent 6,390,231) into the air path. -

Page 22: Connecting The Amplifier To The Loudspeaker
CONNECTING THE AMPLIFIER TO THE LOUDSPEAKER All SONUS Series loudspeakers come with two methods of connecting the amplifier to the loudspeaker. One is a pair of industry standard NL4 type locking connectors, and the other is a pair of ¼” jacks. With the exception of the SONUS subwoofers, which feature a switchable High-Pass output, the four connectors are wired in parallel with each other on all full-range models. -

If the amplifier channels are inadvertently swapped, the low-frequency content could cause damage to the high-frequency driver or your amplifier. At best, it will simply sound very bad. Community SONUS Series - Operation and Installation Manual - Page 26... - Page 27 Wire and cable manufacturers offer multi-conductor cables with 30 or more high current conductors Community SONUS Series - Operation and Installation Manual - Page 27...
- Page 28 The resistance of the wire, the impedance of the load, and the output voltage of the amplifier will determine how much loss occurs in the wire. These parameters also govern the damping factor of the amplifier/speaker combination (more on this later). Community SONUS Series - Operation and Installation Manual - Page 28...
- Page 29 Therefore, keeping cable lengths as short as possible, is the most practical and cost-effective way to maintain a respectable damping factor without incurring undue difficulties. Community SONUS Series - Operation and Installation Manual - Page 29...

When driven hard enough its output voltage can’t swing any higher, so the resultant waveform is said to be clipped (see Figure 10 below).

100 Hz wave is approximately 11.3 feet in length. These extremely long wavelengths cause behavior that’s quite different from their shorter mid and high- frequency counterparts. Community SONUS Series - Operation and Installation Manual - Page 33... -
Page 34: Effect Of Boundary Surfaces On Power Output
A thorough understanding of how low-frequency waves transmit in acoustical environments is very helpful when designing and installing optimum sound systems. We recommend reading, “Fundamentals of Sound” and “Psychoacoustics” by F. Alton Everest in the “Handbook for Sound Engineers” published by Howard Sams & Co.

Page 37: System Equalization
The three corrective methods referred to in the text, equalizing, high-passing, and increasing the slope of the crossover, are all various implementations of equalization. Community SONUS Series - Operation and Installation Manual - Page 37... - Page 38 No matter what technique you use you can’t, of course, EQ a room; you can only EQ the sound system in the room. But much of the world refers to the process of equalizing a system as ‘room-tuning.’ Community SONUS Series - Operation and Installation Manual - Page 38...
- Page 39 In a real life situation the primary room resonant frequency would tend to be much lower, but it’s easier to illustrate the principal in a range where the graphic equalizer has more available bands. Community SONUS Series - Operation and Installation Manual - Page 39...

It also allows the load to easily tip or shift its weight in the hitch. It should always be avoided. Figure 13: Never Reeve Cables! Community SONUS Series - Operation and Installation Manual - Page 43... - Page 44 • For loudspeaker rigging, only rated forged steel shoulder eyebolts purchased from a reputable manufacturer, should be utilized. Community offers this style of eyebolt at a reasonable cost. The SWL or WLL rating of any eyebolt is based on a straight line pull. If the load angle varies from that of a straight line, the load rating rapidly decreases.
-
Page 45: Never Reeve Cables
Threaded fasteners are often used in rigging and mounting systems. As with eyebolts, many of Community’s optional mounting brackets, yokes, and rigging plates utilize threaded fasteners. The fasteners that come with each Community rigging kit are load rated to a sufficient strength to be safe when used within their specified parameters. If replacement bolts are needed, or if additional bolts are required for mounting a bracket to a beam, wall, or ceiling etc., such bolts should be purchased from a reputable manufacturer... - Page 46 Always use your best judgment, just as you do when driving at high speeds in traffic.

It is critically important that you use fasteners with the proper thread pitch. All SONUS Series loudspeakers use the M10 metric fasteners. DO NOT USE THE 3/8-16 UNC FASTENERS! It is very easy to mistake one thread pitch for the other.

10mm Metric fasteners. These fasteners are very similar but they are NOT identical. It is critically important that you use the M10 fasteners with all SONUS Series enclosures. DO NOT USE THE 3/8-16 UNC fasteners under any circumstances. Use of fasteners with the incorrect thread pitch could result in serious harm, injury or death, because the threads will not hold securely under load. -

Now, position the enclosures so that their rear corners are touching and lined up evenly with each other. Tighten the bolts to a setting of 10 to 12 foot-lbs using a torque wrench. Do not overtighten! Figure 16: VFKIT Vertical Fly Kit Assembly Community SONUS Series - Operation and Installation Manual - Page 50... - Page 51 The proper solution is to provide separate cables for each one of the eyebolts.
