Merging Technologies DA8V3S – 8-Channel Line DA Card for HAPI MKIII (192kHz)

OVERVIEW

The Merging Technologies DA8V3S is a premium 8-channel digital-to-analogue expansion card designed specifically for the HAPI MKIII modular networked audio interface. Supporting sample rates up to 192kHz, it delivers exceptionally accurate analogue playback with remarkable transparency, ultra-low distortion and outstanding dynamic range, making it ideal for professional studios, mastering suites, broadcast facilities, immersive audio systems and critical monitoring applications.

Built around Merging Technologies’ latest-generation converter architecture, the DA8V3S incorporates high-performance ESS conversion technology together with dedicated low-phase-noise oscillator circuitry to minimise jitter and maximise stereo imaging. Digitally controlled output trims allow precise system calibration, while auto-mute circuitry eliminates pops during power cycling. The result is one of the quietest and most transparent multichannel D/A converter modules available for professional audio production.

Designed for seamless integration with the HAPI MKIII ecosystem, the DA8V3S provides eight high-quality balanced analogue outputs via a DB25 (AES59/Tascam) connector, offering the flexibility and sonic accuracy demanded by today’s recording, mixing, mastering and immersive audio professionals.
