Review ATLANTIC TECHNOLOGY Servo Controlled Subwoofer Amplifier

The Atlantic Technology SA-700 Servo Controlled Subwoofer Amplifier is a powerful and sophisticated audio component designed to deliver deep, accurate bass for home theater and music enthusiasts. This amplifier is part of Atlantic Technology's SA Series, which is renowned for its advanced technology and high-performance capabilities.

The SA-700 is a Class D design, which means it is highly efficient and produces minimal heat. It is capable of delivering an impressive 700 watts RMS (Root Mean Square) continuous power into a 4-ohm load, with a peak power output of 1400 watts. This makes it an excellent choice for powering larger subwoofers or multiple subwoofers in larger home theaters or music systems.

One of the standout features of the SA-700 is its servo-controlled design. This technology allows the amplifier to actively monitor and correct any deviations in the subwoofer's electrical response in real-time. This results in an incredibly accurate and consistent bass response, with minimal distortion and maximum clarity.

The amplifier also incorporates Atlantic Technology's proprietary Dynamic Bass Boost (DBB) technology. This feature allows the user to temporarily increase the amplifier's output by up to 10dB, providing an extra boost of bass for explosive action scenes or intense music tracks. The DBB can be activated manually or automatically based on the signal being played.

The SA-700 also includes a number of other advanced features to ensure optimal performance and ease of use. These include a variable low-pass filter, which can be adjusted from 40Hz to 200Hz to match the response of the subwoofer and main speakers; a phase switch, which can be used to align the subwoofer with the main speakers for a more cohesive sound; and a volume control, which allows the user to adjust the subwoofer's output level to suit their preferences.

The amplifier's robust construction includes a heavy-duty aluminum heat sink, which helps to dissipate heat and ensure reliable operation even during prolonged use. The SA-700 also features gold-plated RCA inputs and binding post outputs, which provide a secure and high-quality connection to the subwoofer and other audio components.

In summary, the Atlantic Technology SA-700 Servo Controlled Subwoofer Amplifier is a high-performance and versatile audio component that is ideal for home theater and music enthusiasts who demand deep, accurate, and powerful bass. Its servo-controlled design, advanced features, and robust construction ensure optimal performance and reliability, making it a great investment for any audio system.
