Merging Technologies AKD8D Option Card

These remotely controlled Mic/Line Input cards have set 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 (AKD8D).

Features:

• 8 x exceptionally transparent, Swiss designed pre-amplifiers
• Remote/Local switch to Line Level on a per channel basis
• Completely accessible remotely for all parameter changes
• Phantom Power/Phase/Low Cut switchable per channel
• Removes the need for DI boxes
• Allows build-in Mic splitting variants
• Better than 120dB dynamic range
