Details
Controls: Sensitivity switch + fine-adjust pot (100dB range, +80dB to -20dB), HPF select, DI input
I/O: Transformer-balanced input, 10 Megohm DI input (~10dB gain), 4-position HPF (47/82/150/270Hz)
Notes: Single 500-series module; REQUIRES a separate 500-series lunchbox/chassis (not made by Aurora — no Aurora-branded 500-Series Chassis product was found on auroraaudiollc.com/products/, so no chassis entry is included in this dataset). No EQ, so classified as Preamp (form_factor='500-series module' per field guidance). Explicitly stated on Aurora's page: hand-built in North Hollywood, USA, all-steel construction. Current draw: 100mA normal / 130mA all modes active. price_usd=1155 is a dealer (Professional Audio Design) price found via web search; other listings ranged $970 (used) to $1,213 — treated as approximate, not an Aurora-published MSRP.
