setup, it feels purpose-built rather than adapted. Its routing architecture reflects the realities of modern hybrid audio systems. Each slot includes dedicated XLR inputs and outputs, along with the ability to toggle between analog inputs and digital returns. Adjacent slots can also be stereo-linked, simplifying the creation of stereo processing chains without additional patching.
One of the most impactful aspects of the D510 is its ability to create fixed channel strips within the rack itself. A common configuration might include a microphone preamp, compressor, and equalizer assigned to a single input. Once established, this signal chain becomes a consistent processing path that defines the sound at the source. Instead of rebuilding gain structure, compression, and EQ settings week after week, these decisions are made once and remain stable. For churches with rotating volunteers, this dramatically reduces variability and ensures consistent results across services.
The three 500-series modules currently available from Harrison Audio— the 32Cpre +, MR3eq, and Comp form a cohesive frontend signal chain designed for consistency, musicality, and control.
The 32Cpre + provides a warm, transformerbased mic preamp with classic high- and lowpass filters, delivering a strong tonal foundation with flexible input options and precise gain staging. Based on a classic transformercoupled design, it delivers a warm yet precise sound that reflects decades of professional recording heritage. Its high-pass and low-pass filters, drawn from legacy Harrison console designs, provide flexible tonal shaping with a smooth, musical response. With features like front-panel XLR and Hi-Z inputs, phantom power, pad control, and polarity reversal, the 32Cpre + offers both convenience and sonic integrity, establishing a strong and reliable foundation for any signal.
Following the preamp, the Comp module provides dynamic control that is both transparent and musical. Built on a classic analog compressor design, it allows engineers to manage signal dynamics without sacrificing natural feel. Whether smoothing vocal performance, enhancing room ambience, or shaping transient response, the Comp offers precise control through its threshold, ratio, release, and makeup gain parameters. Its gain reduction metering and A / B switching make it easy to dial in settings and evaluate results quickly. In a worship context— where vocal
