Details
Controls: Gain 0 to +64dB in 1dB relay steps, 3 selectable HPF frequencies, 3 impedance settings, 48V phantom (with mute-while-switching), reversible polarity; large 7-segment LED gain display; optional 'Commander' remote control unit with LOCK button
I/O: Balanced mic/line I/O, pair of discrete JFET Direct Inputs (2 meg ohm, 0-40dB gain)
Notes: JUDGMENT CALL: form_factor classified as standalone/desktop rack unit rather than 500-series module - manufacturer text does not describe it as a 500-series card, and it uses a separate optional 'Commander' remote (sold separately), unlike Bento-based 500-series modules. Power supply spec (+/-24V) stated but wattage not given. Single-source price (My Audio Supplies): regular $1,729, sale $1,379 seen.
