Details
Controls: None documented on mic body (fixed cardioid); switches, if any, reside on external power supply unit
I/O: 7-pin Tuchel C70/A connector to external power supply N 920.1 (mic itself not directly phantom-powered)
Notes: FLAG: TUBE microphone requiring dedicated external power supply (N 920.1), unlike the UM 900 which runs on standard 48V phantom - do not confuse the two tube designs. Self-noise 13 dBA/24 dB CCIR468-4, dynamic range 106 dB, weight 400g, dims 185x43mm. price_usd left blank per golden rule - a retailer reference of ~$2,375 was mentioned as 'lowest seen in years' but date/currency confidence is low and not treated as authoritative; manufacturer page lists no price.
