Amplifier Rear Panel Signal Connections

The Model 302 Stereo Power Amplifier offers unprecedented compatibility with associated audio components. When connecting or disconnecting speaker or interconnect cables, the amplifier should be placed in Standby mode (blue POWER INDICATOR LED on the front panel OFF).

If you are using balanced XLR interconnects from your preamplifier or source component, position the INPUT SELECT switch (1) to BALANCED INPUT. If you are using unbalanced RCA interconnects, position the INPUT SELECT switch to UNBALANCED INPUT.

Connect the corresponding interconnect cables to either the BALANCED INPUTS (2) or UNBALANCED INPUTS (3) on each channel. Both RCA and XLR inputs cannot be used for the same channel simultaneously. For example, an unbalanced output connection from a surround processor and a balanced output connection from a CD player cannot both be connected to the same channel at the same time.

A slight mechanical click may be heard when the balanced XLR interconnect cables are correctly installed and locked. The unlocking tab (located on the input connector and labeled “PUSH”) must be pressed to disconnect the XLR interconnect cable from the amplifier.

Unscrew the knob that secures the speaker output connectors on both the LEFT SPEAKER OUTPUT (4) and the RIGHT SPEAKER OUTPUT (5) and pull the securing block out far enough to allow access to the binding posts. Install the positive (usually red) loudspeaker cable spade terminal to the positive (+) binding post and the negative spade terminal to the negative (-) binding post on both the LEFT (4) and RIGHT (5) CHANNEL. Secure the loudspeaker connections by tightening the knob securely with your fingers.

The Model 302 will only accept spade terminations for loudspeaker cables. Banana plugs or bare wire connections cannot be used and must be reterminated with spade connections.

The Model 302 has two pairs of binding posts per channel to facilitate bi-wiring. Both sets of binding posts are active and connected in parallel with no difference in signal quality. If your loudspeakers are capable of bi-wiring and you wish to do so, simply connect one pair of binding posts from each channel to the high frequency terminals of your loudspeakers and one pair of each channel to the low frequency terminals of your loudspeakers.

+Warning: Both positive and negative outputs are electrically active with respect to chassis

and/or system ground potential. Therefore, this amplifier cannot be used in certain loudspeaker switching configurations, such as those used in retail demonstrations. Failure to avoid these precautions may short the outputs to ground and can result in damage to the amplifier and will void the warranty.

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.
