SPEAKER SYSTEMS MANUAL
Dear Sound Professional: Thank you for choosing EV products. For more than 70 years, we have persevered to design, engineer, and manufacture the most innovative and highest quality audio products for indoor and outdoor spaces, including offices, houses of worship, live music venues, auditoriums and stadiums. This perseverance has led to our pioneering new technologies that have become industry standards: constant directivity horns, manifold technology, Variable-D® microphones, hum-bucking coils for microphones, and the inclusion of ultra-light weight neodymium in magnet structures (previously only utilized by the auto industry) for microphones and loudspeakers, to name just a few. It is our pleasure to provide you with the audio solution best suited for your critical sound reinforcement needs. [. . . ] It shall be finished in black or white acrylic paint or available unfinished. A total of twelve 3/8-16 threaded mounting/suspension points shall be provided, (three each on top and bottom, two per side, two on rear). The front of the loudspeaker shall have a powder-coated perforated 16 GA steel grille. Grille mounting shall allow for acoustically transparent fabric to be applied without any noticeable protrusions or fasteners. The two-way full range loudspeaker shall be the Electro-Voice model FRi-122/64.
FRi-181S The subwoofer loudspeaker system shall incorporate one passive or biampable 18-in. LF transducer mounted in a vented, slot-loaded enclosure tuned at optimum low frequency response. System frequency response shall be 45 Hz to 160 kHz (-3 dB) measured on axis. The loudspeaker shall produce a sound pressure level (SPL) of 97 dB (100 dB half-space) on axis at 1 meter with a power input of 1 watt, and shall be capable of producing an output of 123 dB (132 dB half-space) on axis at 1 meter. The loudspeaker shall handle 400 watts of amplifier power long-term (EIA Standard) and shall have a nominal impedance of 8 ohms. The loudspeaker enclosure shall be trapezoidal in shape with side draft angles of 7. 5 degrees each. It shall be constructed of 13 ply void-free cross-grain-laminated Birch plywood and shall employ extensive internal bracing. It shall be finished in black or white acrylic paint or available unfinished. A total of sixteen 3/8-16 threaded mounting/suspension points (4 each top, bottom, sides) shall be provided. The front of the loudspeaker shall have a powder-coated perforated 16 GA steel grille. Grille mounting shall allow for acoustically transparent fabric to be applied without any noticeable protrusions or fasteners. The sub bass loudspeaker shall be the Electro-Voice model FRi-181S.
FRi Series Warranty
F R i
Uniform Limited Warranty
Electro-Voice products are guaranteed against malfunction due to defects in materials or workmanship for a specified period, as noted in the individual product-line statement(s) below, or in the individual product data sheet or owner's manual, beginning with the date of original purchase. If such malfunction occurs during the specified period, the product will be repaired or replaced (at our discretion) without charge. Exclusions and Limitations: The Limited Warranty does not apply to: (a) exterior finish or appearance; (b) certain specific items described in the individual product-line statement(s) below, or in the individual product data sheet or owner's manual; (c) malfunction resulting from use or operation of the product other than as specified in the product data sheet or owner's manual; (d) malfunction resulting from misuse or abuse of the product; or, (e) malfunction occurring at any time after repairs have been made to the product by anyone other than Electro-Voice Service or any of its authorized service representatives. Obtaining Warranty Service: To obtain warranty service, a customer must deliver the product, prepaid, to Electro-Voice Service or any of its authorized service representatives together with proof of purchase of the product in the form of a bill of sale or receipted invoice. A list of authorized service representatives is available from Electro-Voice Service at 12000 Portland Avenue, Burnsville, MN 55337. Ph: (877) 863-4166 Incidental and Consequential Damages Excluded: Product repair or replacement and return to the customer are the only remedies provided to the customer. Electro-Voice shall not be liable for any incidental or consequential damages including, without limitation, injury to persons or property or loss of use. Some states do not allow the exclusion or limitation of incidental or consequential damages so the above limitation or exclusion may not apply to you. [. . . ] For bi-amping the FRi Series in more complex array configurations with delays and a greater need for equalization, we recommend the EV Dx38 Digital Sound System Controller, which incorporates all necessary crossover, parametric EQ, shelving EQ, low- and highpass filters, alignment (delay), compressor and limiter functions. (Settings for the Dx38 are available on the EV Web site: www. electrovoice. com. )
Typical FRi Input Panel
All FRi full range enclosures feature very high quality barrier strip input terminations for ease of installation and secure connections.

Recommended Configurations for FRi Systems
· Bi-amp Operation · All Passive Operation · Tri-amp Operation BEST BETTER NOT RECOMMENDED AUDIO INPUT
BI-AMPED MONO ARRAY
Due to the inherent designs and efficiencies of the FRi systems, there is no cost effective reason to utilize all active operation in either mono or stereo mode. Actual cost of electronics and amplification will be determined by the total number of FRi cabinets configured within the array. Due to load requisites some array configurations may not be feasibly powered in all passive mode with typical amplifiers available.
Cost Effective Fidelity for the FRi System
Based on cost effectiveness of the entire system (loudspeakers, processors, amplifiers), bi-amp operation combines the overall best frequency response and value. [. . . ]
