Details
Controls: Sample-rate select (44.1-192kHz), Triode/Pentode/Tape process amount knobs, ANA/DIGI operating mode, dither setup (16/24-bit), level meter with peak hold
I/O: Balanced XLR analog in/out, AES XLR in/out, S/PDIF RCA in/out, TOSLink optical in/out, word clock BNC input plus multiple word clock outputs
Notable use: 5th-generation 'Quantum' successor to the original HEDD-192; widely used to add analog-style harmonic warmth to digital recordings
Notes: Supersedes the earlier HEDD-192, which no longer has an active page on cranesong.com (checked directly: 404) and is therefore excluded from this catalog per the 'current models only' scope rule; the HEDD Quantum manual itself states its max analog output (+24.5dBu) exceeds the original HEDD-192's (~+18.5dBu), confirming the successor relationship.
