Neumann ADO8V3S 8ch Mic/Direct Outs A/D Card for Hapi Mk III

About: Neumann ADO8V3S 8ch Mic/Direct Outs A/D Card for Hapi Mk III

The ADO8V3S input card is an outstanding addition to Merging the 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 ADO8V3S sets a new standard in audio circuit design, and it even includes analog direct outs (post-mic-pre) for monitoring or external processing.

The ADO8V3S supports sample rates up to 192 kHz.
