Notes: FLAG: opto-tube compressor (optical/photocell gain-reduction element). price_usd is a Sweetwater dealer-listed price, not a confirmed manufacturer MSRP; this figure matched the CL 1B search result exactly, which is a plausible coincidence (both often list near $5,250) but could not be independently cross-verified due to retailer site access limits - treat as approximate/unverified. Standard 19" rack unit, not 500-series.
