i3™ Three-Stage Circuit Topology — Power Protection for the Real World

iPOWER's i3™ (instantaneous, impenetrable, and virtually indestructible) circuit topology represents a breakthrough in power protection technology. A three-stage design comprised of Gas Tubes, Metal Oxide Varistors (MOV's) and a proprietary Low-Impedance In-Line Filter, the i3™ circuitry delivers instantaneous protection.

Most MOV-based surge protection devices use a circuit topology that is sacrificial in nature. Like an air bag in an automobile, they are designed to “blow up,” sacrificing their internal circuitry in order to protect the connected equipment during a severe surge event. Sooner or later they fail in the line of duty leaving connected equipment unprotected. As a radical departure from this philosophy, all Niles iPOWER™ products with i3™ protection technology are non-sacrificial in nature. This unique design enables iPOWER™ to protect your equipment time and time again.

While UL’s® most rigorous standard for voltage let through is 330 volts, Niles iPOWER™ products with i3™ protection technology have a consistent clamping level of less than 300V. In addition, all iPOWER™ products clamp at a mere 40V over peak standard line voltage (ANSI/IEEE C62.45 6000V 100 kHz Ring Wave Test), adding a level of protection rarely found in the industry.

iQ™ Optimal Q Noise Filtration

All of the Power — None of the Noise. Computers, household appliances, and RF broadcasts can introduce "noise" onto the AC power line, obscuring audio detail and video resolution. By their very nature, conventional AC power line noise filtration circuits limit electrical current flow, stealing the “punch” from high-current power amplifiers. The Niles iPOWER iQ™ optimal Q impulse noise fil- tration circuitry simultaneously achieves both noise reduction and the proper power line loading necessary for dynamic performance. Through careful research and with the deployment of

advanced electrical components, a sophisticated design that varies the Q of the circuit topology was created. With this design, iPOWER™ products achieve an outstanding 50dB of common mode rejection and 60dB of differential mode rejection—without current choking. iPOWER™ delivers both the performance

iQ™ reduces up to 99.9% (60dB) of AC power line noise. and the power.

AC-8CX specifications

The Niles Audio AC-8CX is a premium in-ceiling speaker that combines advanced technology with exceptional sound quality, making it an appealing choice for home audio enthusiasts. Designed for versatile applications, this 8-inch speaker is perfect for producing high-fidelity sound in both residential and commercial settings.

One of the standout features of the AC-8CX is its 8-inch polypropylene woofer, which is designed to deliver deep, rich bass response. This is complemented by a 1-inch soft dome tweeter that ensures clear, detailed high frequencies. Together, these components create a well-balanced audio profile that reproduces music, movies, and dialogue with remarkable clarity and accuracy.

Niles Audio has incorporated its innovative Controlled Coverage Technology into the AC-8CX. This technology minimizes off-axis sound dispersion, which means that listeners not directly in front of the speaker still enjoy a consistent sound experience. This is particularly advantageous in larger rooms where speaker placement can be challenging.

Installation of the AC-8CX is designed to be straightforward, featuring a low-profile mounting design that allows it to blend seamlessly with any ceiling. The speaker includes adjustable dog-ear brackets, ensuring a secure fit in a variety of ceiling types. Additionally, the magnetic grille is paintable, allowing homeowners to customize the look to match their decor while making the speaker virtually invisible.

Durability is also a noteworthy characteristic of the AC-8CX. The speaker features moisture-resistant materials, making it suitable for use in humid environments such as bathrooms or kitchens. This durability ensures that the speakers maintain their performance and aesthetic appeal over time, even in challenging conditions.

The Niles Audio AC-8CX is designed to handle a wide range of power, with a recommended amplifier power of 10 to 120 watts. This flexibility allows it to be integrated into various home audio systems, whether in a multi-room setup or as part of a dedicated home theater system.

In summary, the Niles Audio AC-8CX offers an impressive blend of sound quality, innovative technology, and user-friendly features. Its robust design, versatile installation options, and advanced sound reproduction capabilities make it an excellent choice for anyone looking to enhance their audio experience in a discreet and stylish way. Whether for music enjoyment or home theater applications, the AC-8CX stands out in the competitive audio market.
