Amplifier Rear Panel Power Connections

Important: Please strictly follow the following steps outlined below in order before operating your Model 302 Stereo Power Amplifier.

KVerify that the VOLTS AC input identified on the rear panel near the AC input socket is the same as the AC mains voltage in your area. If the voltage does not match, DO NOT CONNECT THE AMPLIFIER TO AC POWER and contact your dealer immediately.

LVerify that the AC MAINS circuit breaker is closed (no white area visible on breaker).

MInstall the AC Power Cable between the amplifier and your AC mains outlet.

NConnect the 12V Remote ON/OFF Mini-plug Connector (See Below).

Note: Due to the exceptionally low power consumption rating of the Model 302, it is recommended that the unit not be disconnected from AC mains unless the amplifier is to be moved or reinstalled in another location. It is recommended that the amplifier be placed in Standby mode rather than disconnected from the AC mains power when the amplifier is not in use.

The 12V REMOTE ON/OFF 1/8” (3.5 mm) mini-plug connector (4) is provided on the rear panel of the Model 302 for remotely switching the amplifier between Operational and Standby modes. When connected to another component with the proper circuitry, the amplifier standby function can be turned ON and OFF remotely in a custom installation, theater, or automated system setup. Connection requirements are illustrated below.

Please be aware that the remote feature simply places the amplifier in STANDBY mode and does not disconnect the unit from power or AC mains.

Please contact your dealer for further information about the use and configuration of this feature.

302 specifications

Jeff Rowland Design Group (JRDG) is renowned for its commitment to high-end audio equipment, and the Model 302 amplifier is a testament to that legacy. This amplifier exemplifies not only sonic performance but also the innovative technologies that JRDG employs in its designs.

The Model 302 is a stereo amplifier that delivers outstanding audio fidelity, rated at 150 watts per channel into 8 ohms, with a remarkable 300 watts into 4 ohms. It is crafted to drive a wide range of speakers, making it extremely versatile, and ensuring that it can perform optimally in various audio setups. The amplifier presents an unmatched dynamic capability, allowing it to reproduce both the most delicate notes and the most powerful crescendos with equal clarity and precision.

One of the standout features of the Model 302 is its use of power supply regulation. JRDG employs a proprietary technology known as "Dynamic Power Management," which continuously adjusts the power supply in response to the demands of the audio signal. This dynamic approach helps maintain low distortion and high efficiency, resulting in a clean and accurate sound reproduction. The design minimizes noise and interference, ensuring an immersive listening experience.

Additionally, the Model 302 showcases an elegant design, featuring a minimalist aesthetic that is characteristic of Jeff Rowland's philosophy. Its understated yet sophisticated look is complemented by a chassis that effectively dampens vibrations, further enhancing audio performance. The construction itself uses high-quality materials, ensuring durability and longevity, appealing to both audiophiles and casual listeners alike.

The amplifier also incorporates advanced thermal management technology, designed to keep the unit cool even during extended periods of intense use. This is essential for maintaining consistent performance and avoiding overheating, which can negatively affect sound quality.

Overall, the Jeff Rowland Design Group Model 302 epitomizes high-end audio engineering. With its powerful performance, innovative features, and timeless aesthetics, it appeals to discerning listeners who seek not just a component, but a significant part of their audio journey. The Model 302 is a celebration of what can be achieved when technology and art converge in pursuit of perfect sound.
