Merging Hapi Option Card AKDG8D / AKDG8DP
Brand: Merging
IOM-H-AKDG8D / AKDG8DP
These remotely controlled Mic/Line Input cards are 3rd generation Dual Gain topology designs, inspired from the Anubis outstanding Preamps, that show zero tolerance to any compromise on the audio quality.
A new benchmark in analog circuitry design, and provide additionally a Line level post Mic-pre “Direct Out” output.
Available in models that work up to 192kHz (AKDG8D) and DXD/DSD256 (AKDG8DP)
