Grace Design m908 AD8 Dante is a multi-channel monitor controller with 8-channel A/D conversion and a Dante network module, supporting formats from stereo to Dolby Atmos and Sony 360RA, up to 22.2. The Dante card configuration integrates the system into a modern audio-over-IP infrastructure, giving the engineer reference multi-channel monitoring with 32 network channels and a full DSP complement for room correction, while retaining the option to expand analog inputs to 16 channels.
Reference immersive monitoring on a Dante network
An engineer working in an audio-over-IP system needs a multi-channel monitor controller integrated into the network without extra converters and analog cabling. The m908 AD8 Dante delivers reference A/D and D/A conversion with a fourth-generation s-Lock PLL synchronised to the Dante network clock, 12 bands of parametric room correction EQ across each of 24 channels — 288 bands in total in 64-bit fixed-point filters — and full support for Dolby Atmos and formats up to 22.2. The AD8 configuration with one ADC module provides 8 analog input channels, expandable to 16 by adding a second module.
Dante and a flexible I/O architecture
The Dante card provides 32 channels of network audio I/O up to 192 kHz over two Gigabit Ethernet ports with redundant mode support, which matters directly in broadcast and installation applications where a single link failure cannot interrupt the signal. Standard digital inputs cover 68 channels via AES3, ADAT, USB, S/PDIF and TOSLINK, and a 16-channel balanced analog output plus 24-channel AES3 Out ensure full integration with existing studio infrastructure. Sonarworks SoundID Reference integration, a driver-free web interface and an RCU remote with talkback, SPL meter and up to 8 CUE paths round out session control.
