Merging Technologies 8ch Mic/Line A/D & D/A V3 Expansion Card DSD/DXD

About: Merging Technologies 8ch Mic/Line A/D & D/A V3 Expansion Card DSD/DXD

The ADO8V3P input card is an outstanding addition to the Merging Hapi Mk III audio mainframe.

With 8 mic/line inputs, it delivers unparalleled audio quality and a dynamic range of an impressive 139 dB (A).

The Swiss-designed preamps offer up to 78 dB of gain with exceptional transparency, thanks to Merging’s unique 3rd generation dual gain topology design. Its remote accessibility allows you to easily adjust all parameters for each channel. The ADO8V3P sets a new standard in audio circuit design, and it even includes analog direct outs (post-mic-pre) for monitoring or external processing.

The Premium card ADO8V3P has superior specifications and supports sample rates up to 352.8 kHz (DXD) and 384 kHz as well as bitstream formats up to DSD256.
