If you are a recording studio, a musician looking to record, or a podcaster looking for a high-quality mic preamp at a great price, check out our line of microphone preamplifiers! The PC01 is a standalone single channel chassis with DI, which is great for a podcaster or singer/songwriter who may only need one or two preamps. The CH02 chassis can accommodate up to 8 channels! We have brought back many of the same great designs including the N72 (Neve), A12B (API), and J99 (Jensen/John Hardy), using the same high quality components that have always been used in the Seventh Circle Audio products.
