Details
Controls: adjustable gain and time delay, variable crossover frequency, high-pass/low-pass filters, pink noise generator, USB link to Speaker Manager software (1/3 octave 31-band graphic EQ, selectable parametric EQ, room correction input)
I/O: 1x balanced XLR analog input (-10dBu/+4dBu switchable); 1x AES/EBU digital input (XLR, 110 ohm) with automatic analog/digital switching, digital pass-thru, and digital stereo L/R selector; USB data port
Notes: Building block of the Star System One modular monitoring line (also sold individually). Accepts both analog XLR and AES/EBU digital inputs with DSP-based bass management -- classified analog_or_digital=digital because signal path is DSP/converter-based; FLAG this judgment call. Weight discrepancy between sources: product page text states 50 lbs, official spec-sheet PDF states 55 lbs -- flagging, not guessing which is correct. price_usd of $1,995 (single unit) is the published list price from Blue Sky's Jan 2014 NAMM launch press release -- current 2026 pricing not published on site.
