HORUS OPTIONAL CARDS

IOM-HORUS AD8/AD8P
These remotely controlled Mic/Line Input cards have set a new benchmark in analog circuitry design.
Available in models that work up to 192kHz (AD8) and DXD/DSD256 (AD8P)
HORUS-AD8/AD8P 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/Phase/Low Cut switchable per channel
• Better than 120dB dynamic range
