Harrison Audio D510mx Mixer card

The Harrison D510mx is a dual-slot 500 Series mixer module that turns the D510r rack into a fully featured 10x2 analogue summing mixer with advanced monitoring capability.

Professional Analogue Summing for the D510 System

Harrison positions the D510mx as the central control module for engineers who want the depth, weight and dimensionality associated with their classic analogue consoles, while benefiting from the flexibility of a modular 500 Series workflow. The unit occupies two slots of the D510r rack and provides a stereo summing path for eight remaining 500 Series modules alongside the two fixed analogue inputs on slots nine and ten. Each channel offers level and pan controls, so the engineer shapes precise stereo imaging while preserving the characteristic punch and harmonic detail that defines Harrison summing.

Modern Monitoring Architecture

The D510mx incorporates two completely independent headphone outputs, each with its own blend control. This feature allows the engineer to create cue mixes that combine the analogue summing output with other signals for detailed monitoring. When the system includes the D510dante interface card, the headphone section expands further by receiving audio from any Dante-connected device, including DAW returns, external converters or remote stage boxes. This flexibility allows the D510mx to function as the monitoring hub of a hybrid studio, bridging direct analogue output with networked digital audio systems.

Integrated Workflow Between Classic Sound and Contemporary Control

The D510mx merges the sound of Harrison’s acclaimed analogue topology with the modular freedom of the D510 platform. Engineers route any combination of 500 Series processors through the rack and shape the final mix through the D510mx summing section, achieving colour, clarity and stereo depth with direct hands-on control. Harrison designed the module so that the traditional aesthetic of their large-format consoles meets the adaptability required by modern hybrid production, with consistent gain staging, intuitive panning and stable headphone monitoring built directly into the rack.
