Design and Engineering

The D600 utilizes a Class D amplifier architecture with a power transistor output stage. This design allows the amplifier to deliver dedicated subwoofer power while maintaining efficient operation and a compact footprint.

The amplifier accepts low-level input signals from 0.3V to 6V and operates within a voltage range of 10V to 16V, making it compatible with a wide variety of source units and audio processors.

To support system integration, the D600 includes adjustable subsonic and low-pass filters, allowing the amplifier to be configured according to the requirements of different subwoofer systems and enclosure designs.

The built-in bass boost control further expands tuning flexibility by allowing additional low-frequency adjustment when required.

Sound Performance

The D600 is designed to reproduce low frequencies with sufficient energy, good dynamic behavior, and deep bass extension.

Its sound character focuses on delivering the weight and atmosphere of the lower octaves while maintaining control throughout the operating range. The amplifier is capable of producing bass that extends deeply into the low-frequency region while preserving the dynamic changes present in music.

The combination of dedicated subwoofer amplification and adjustable filtering allows the D600 to support a wide range of musical styles and low-frequency requirements.

Product Positioning

Within the Rebec amplifier lineup, the D600 serves as a dedicated mono amplifier for passive subwoofer systems.

Positioned below the D1200, the D600 offers a balance between output capability, installation flexibility, and low-frequency performance. Its 600W RMS output makes it suitable for a broad range of subwoofer applications while maintaining the compact design and efficiency associated with Class D amplification.

Design Philosophy

The D600 was developed with a clear objective: to provide dedicated low-frequency amplification in a compact and efficient package.

By combining practical power output, flexible tuning controls, and a focus on deep and dynamic bass reproduction, the D600 is designed to become a reliable foundation for subwoofer systems within the Rebec ecosystem.
