Harrison D510MX – 500 Series 10×2 Analog Summing Mixer Module
OVERVIEW
BUILD YOUR CUSTOM 500 SERIES ANALOG SUMMING MIXER
Pair the D510r with the optional D510mx mixer module to transform your system into a powerful 10×2 analog summing mixer. Designed to integrate into two slots of the Harrison D510r 500 Series rack, the D510mx gives you the flexibility to create stereo mixdowns from any of the eight remaining 500 Series module slots, alongside the two analog inputs to slots 9 and 10. With level and pan controls on each channel, plus dual independent headphone outputs with ‘blend,’ get the renowned weight and ‘3D’ depth that Harrison analog summing brings to productions while enhancing your headphone monitoring capabilities.
When used in combination with the D510dante audio interface card, the dual headphone outputs can create monitor mixes from either the direct analog output or from any connected device on the Dante network.
With an almost infinite number of configurations, the Harrison D510 rack paired with the D510mx mixer module can create an extremely powerful (and portable) eight-channel tracking system housed in only 3U – we said it was flexible!
