The Merging Technologies HAPI ADO8V3S is a premium 8-channel mic/line input card designed for the Hapi Mk III audio mainframe, delivering exceptional audio fidelity with Swiss-engineered preamps offering up to 78 dB of gain, an extraordinary dynamic range of 139 dB (A-weighted), direct analogue outputs, full remote-control capabilities, and support for sample rates up to 192 kHz, making it an essential tool for professional audio recording and production environments.

Exceptional Audio Performance and Design

Engineered to meet the demands of high-end audio production, the HAPI ADO8V3S combines transparency, precision, and reliability. Its eight mic/line inputs are equipped with state-of-the-art, Swiss-designed preamplifiers that ensure maximum clarity and fidelity. These preamps, featuring Merging Technologies’ innovative third-generation dual gain topology, provide up to 78 dB of gain while maintaining pristine sound quality without introducing noise or distortion. The analogue-to-digital conversion achieves an impressive dynamic range of 139 dB (A-weighted), setting a benchmark in audio performance.

Flexible Control and Connectivity

The HAPI ADO8V3S offers full remote access to all parameters, enabling precise adjustments for every channel without physical intervention. Each channel allows for phantom power, polarity inversion, low-cut filtering, and impedance switching, providing unmatched flexibility for professional audio setups. A remote/local switch permits seamless transitions to line-level operation on a per-channel basis, enhancing adaptability for various recording scenarios. The inclusion of direct analogue outputs (post mic-preamp) for each channel allows real-time monitoring or external signal processing, eliminating the need for additional DI boxes.

Seamless Integration and Reliability

Two 25-pin Sub-D connectors ensure robust connectivity, simplifying integration into existing audio systems. The preamps also support MIDI remote control, offering additional versatility for advanced automation workflows. Auto-mute circuitry prevents unwanted noise or signal pops during power cycling, safeguarding both equipment and recorded material. With support for sample rates up to 192 kHz, the ADO8V3S meets the requirements of modern high-resolution audio production workflows.

A Benchmark in Professional Audio Technology

The Merging Technologies HAPI ADO8V3S represents a fusion of cutting-edge technology, exceptional design, and engineering precision. Its superior audio performance, versatile controls, and robust connectivity make it a cornerstone for any professional audio engineer seeking uncompromised quality and reliability in their recording systems.
