The Focusrite ISA One is an excellent way to tap into the legacy of the Forte console in an ultra-portable format. The ISA One is built on the topology of the original ISA 110, including the Lundahl L1538 transformer and Zobel network. Inputs for microphone-, line-, and instrument-level sources cover all of the bases. A variable impedance selector also lets you dial in the response you need. Plus, the ISA One's instrument- and microphone-level inputs run in parallel, so you can blend the direct signals.
