Details
I/O: 1x 7-pin XLR male stereo mic output to dedicated external PSU; PSU provides two 3-pin XLR audio outputs
Notable use: Royer describes it as 'the pinnacle of Royer's stereo ribbon microphone designs' (per Royer marketing copy).
Notes: FLAG: Top-of-line stereo tube ribbon mic, channel_count=2. Powered by dedicated external tube PSU (plate 135VDC@2mA, filament 6VDC@150mA per channel), not 48V phantom, so phantom_power=false. Self-noise <18dB. Country of manufacture inferred from company-wide Burbank, CA statement. Price = Sweetwater street price (USD).
