AudioControl Model D4600 Amplifier Review

I. Introduction

AudioControl has been a notable name in high-performance audio systems, and the Model D4600 Director Series Amplifier is a testament to their commitment to quality. With an impressive array of features tailored for custom home theater and multi-zone audio systems, this amplifier looks to set a high bar for both power and performance.

II. Design and Build Quality

The Model D4600's sleek 2U rack design is both functional and aesthetically pleasing, fitting seamlessly into a standard audio rack. The unit's 21-pound weight strikes a good balance between heft, indicative of quality components, and manageability for installation. Attention to detail in the build suggests that the D4600 is made to withstand the rigors of both residential and commercial use while maintaining a professional look.

III. Power and Performance

Boasting 100 watts of power per channel at 8 ohms and doubling to 200 watts at 4 ohms, the D4600 is versatile for various speaker configurations. Bridged mono mode pushes the power output to an impressive 400 watts at 8 ohms, catering to demanding speakers with ease. The high signal to noise ratio (>95 dB) and low crosstalk (>80 dB) ensure that audio is delivered with exceptional clarity, free from interference and noise. Additionally, the damping factor of >300 is indicative of the amplifier's ability to control speaker drivers for tight, precise bass response.

IV. Digital Signal Processing (DSP) and Customization

The D4600's Digital Signal Processing is at the core of its customization prowess. With digital profiles for popular architectural loudspeakers, setup and calibration are streamlined, ensuring optimal sound in any environment. The comprehensive graphic and parametric EQ settings per zone allow for fine-tuning that can satisfy the most discerning audiophile's preferences. The flexibility of the audio matrix is a boon for custom installations, allowing for tailored soundscapes across different zones.

V. Connectivity and Integration

Integration with leading 3rd party control systems such as Crestron, Savant, RTI, and Control 4 means the D4600 can easily become the heart of a sophisticated smart home audio setup. While the integration is a strong point, it's worth noting that additional equipment may be required to fully leverage these systems. The Ethernet port enhances monitoring and programming, while the 12 Volt trigger control adds convenience for power management.

VI. Energy Efficiency and Environmental Considerations

The D4600's energy consumption is commendable, with a standby draw of less than 2 watts and an idle consumption of 53 watts. At full power, it demands 2400 watts, which is typical for an amplifier of this caliber. Users can take comfort in the amplifier's efficient power use during normal operation, contributing to a reduced environmental impact and potentially lower electricity costs.

VII. Warranty and Support

AudioControl's five-year warranty is a significant statement of confidence in the D4600's reliability. This comprehensive coverage, coupled with the manufacturer's reputation for customer support, provides peace of mind for the investment.

VIII. Pros and Cons

The D4600 shines with its high power output, advanced DSP features, and robust integration options. However, the limited availability for in-store pickup only could be a drawback for some potential buyers, and the need for additional integration equipment could add to the total cost of ownership.

IX. Price and Value Proposition

Priced at $3,999.95, the Model D4600 sits at a premium segment of the market. Its advanced features and performance justify the cost for users who demand high-quality, customizable audio distribution in their homes or commercial spaces. When compared to similar offerings, the D4600 holds its own, especially considering the built-in DSP and compatibility with major control systems.

X. User Experience and Use Case Scenarios

The D4600 is well-suited for a range of applications, from high-end home theaters to multi-room audio systems that require a centralized, powerful, and flexible amplifier.
