Merging Technologies DA8V3P – 8-Channel Line D/A Converter Card for HAPI MKIII (DSD/DXD)

OVERVIEW

The Merging Technologies DA8V3P is a premium 8-channel line D/A converter card designed specifically for the HAPI MKIII modular networked audio interface. Supporting PCM sample rates up to 384kHz, DXD and DSD256, it delivers world-class analogue output performance for professional recording, mastering, broadcast, immersive audio and critical monitoring applications. With a typical dynamic range of 128dB (A-weighted), exceptionally low THD+N and remarkably low noise floor, the DA8V3P has earned a reputation as one of the finest multichannel D/A conversion solutions available.

Every DA8V3P card is individually measured to the highest manufacturing tolerances, ensuring exceptional consistency and transparency across all eight output channels. Advanced low-phase-noise oscillator circuitry minimises jitter for improved stereo imaging and detail, while integrated analogue auto-mute circuitry prevents clicks and pops during power cycling or sample-rate changes, protecting both loudspeakers and listeners. Digitally controlled output trims and selectable international operating levels further simplify system integration in professional installations.

Designed for engineers who demand uncompromising audio quality, the DA8V3P combines reference-grade performance with seamless integration into the HAPI MKIII platform. Whether used in mastering studios, Dolby Atmos facilities, classical recording, broadcast production or mission-critical monitoring environments, it delivers the precision, transparency and reliability expected from Merging Technologies’ premium conversion systems.
