Rebec D1200 Mono Class D Subwoofer Amplifier

Product Overview

The Rebec D1200 is a high-power mono Class D amplifier developed specifically for passive subwoofer applications. Designed to provide greater output capability than the D600, the D1200 is intended for systems that require additional low-frequency power while maintaining the efficiency and flexibility of a dedicated mono amplifier.

With up to 1200W RMS output at 1Ω, the D1200 delivers substantial power reserves for a wide range of subwoofer systems. Its combination of adjustable crossover controls, compact dimensions, and high-output Class D architecture makes it a versatile solution for low-frequency amplification.

Within the Rebec amplifier lineup, the D1200 represents a higher-output option for users seeking increased bass capability and support for larger subwoofer configurations.

Design and Engineering

The D1200 utilizes a Class D amplifier circuit with a power transistor output stage. This architecture is designed to provide high output capability while maintaining efficient operation and manageable installation requirements.

The amplifier accepts low-level input signals from 0.3V to 6V and operates within a voltage range of 10V to 16V, allowing compatibility with a broad range of source units and digital signal processors.

To support different subwoofer system requirements, the D1200 incorporates adjustable subsonic and low-pass filters. These controls allow users to configure the amplifier according to enclosure design, subwoofer characteristics, and system objectives.

A variable bass boost function provides additional flexibility when extra low-frequency emphasis is desired.

Power Delivery

One of the key characteristics of the D1200 is its increased output capability compared with the D600.

The amplifier delivers 500W RMS at 4Ω and 800W RMS at 2Ω, providing additional power reserves for systems that require stronger low-frequency reproduction. At 1Ω, output increases to 1200W RMS, allowing the amplifier to support larger subwoofer systems and drivers that benefit from higher power input.

This additional output capability expands the range of subwoofer applications that can be supported within the Rebec ecosystem.

Sound Performance

The D1200 is designed to reproduce low frequencies with strong energy, deep extension, and good dynamic behavior.

Its sound character emphasizes the ability to reach deep bass frequencies while maintaining sufficient output and impact throughout the low-frequency range. The amplifier is capable of supporting bass reproduction that conveys both weight and atmosphere, helping to reinforce the foundation of the music.

Dynamic changes within the low-frequency spectrum are reproduced with stability, allowing bass passages to remain controlled while preserving their sense of energy and movement.

Compared with the D600, the D1200 provides additional power reserves, making it suitable for systems that require greater low-frequency output or larger subwoofer configurations.

Product Positioning

Within the Rebec D-Series lineup, the D1200 is positioned above the D600 as a higher-output mono amplifier.

While both models share the same Class D architecture and bass control features, the D1200 offers significantly greater power capability and is intended for larger subwoofer applications. This makes it a suitable choice for users seeking additional low-frequency authority while retaining the flexibility and efficiency of a dedicated mono amplifier.

Design Philosophy

The D1200 was developed to provide a balance between power, control, and low-frequency performance.

By combining a dedicated mono Class D platform with adjustable tuning controls and increased output capability, the amplifier is designed to support a wide variety of subwoofer systems while maintaining the deep, energetic, and dynamic bass character that defines the Rebec D-Series.
