I’ve used these API units in Lunchbox form and they are amazing. I once did a A/B test comparing my mic with 5 Powercore plug-ins vs a lone API 512c compressor. No matter how I tweaked things the raw 512c killed it. The new Channel Strip puts the very best API has to offer in a single rackmount unit. Expect a street price around $2700. If you do vocals and your sticking with making music for the next 10+ years it’s worth the price.
“The Channel Strip is made up of a 512c mic pre, our famous 550A EQ, the 527 Compressor and the 325 Line Driver, combining many well-known and highly coveted pieces in one package. Each processing piece can be switched in or bypassed individually and a Flip switch allows the compressor to be placed after the EQ if desired. Additionally, The Channel Strip includes an insert point, sidechain input, multiple metering locations as well as the famous API 2520/transformer combination.” – apiaudio.com
