HAPI MKII User Manual
IOM-H-ADA8S/ADA8P
These remotely controlled Mic/Line Input and Output cards are 3
rd
generation Dual Gain topology
designs, inspired from the Anubis outstanding Preamps, that show zero tolerance to any compromise
on the audio quality.
Available in models that work up to 192kHz (ADA8S) and DXD/DSD256 (ADA8P)
Using those combined 8 channel Mic/Line In and Line Out cards allow the Hapi to be configured with up
to 16 channels of Analog In/Out.
IOM-H-ADA8S/ADA8P 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/Impedance switchable per channel
• Dynamic range of 139dB (A-weighted, typ) on the Line inputs
• Auto-mute circuitry for “no-pop” power cycling
• Digitally controlled output trims for line up procedures
• Dynamic range of 124dB (A-weighted, typ.) on the Line outputs
