IOM-H-AD8D / AD8DP -
Legacy Product
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 (AD8D) and DXD/DSD256 (AD8DP)
IOM-H-AD8D / AD8DP Key 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/Polarity Invert/Low Cut switchable per channel
• Removes the need for DI boxes
• Allows build-in Mic splitting variants
• Better than 120dB dynamic range
