I've got a tender spot for UREI recording stuff. There are so many different units that serve different purposes. They all seem to lie in the same function/availability/price category as well - they are certainly capable, they're always surfacing as used items for sale, and they tend to stay under the thousand mark.
Anyway, this one is the UREI 546 Dual Parametric Equalizer. On each channel, you've got low and high cut filters, variable bandwidth controls for each band (Low, Low-Mid, High-Mid, High - also, pull out the bandwidth knob and you've bypassed that band), detent frequency selection and stepped boost or cut control. This thing looks almost good enough for mix bus or mastering! Functionality reminiscent of a certain Manley piece? Sure, but very different guts. Cheap on eBay!
