The Iron Age 500 series 622 channel strip module was designed as a flexible tracking and mix solution. The module is packed with features like no other in the 500 series format and has the instant Iron Age tone.

Each 622 features a discrete mic / line amp that offers up to 60 dB of gain in mic mode. In line mode it is a classic balanced input. The pad engages a 20 dB pad in mic, and a 6 dB pad in line.

The preamp stage feeds an active high pass filter set for 60Hz, followed by a simple and powerful VCA compressor. The output stage is a three band “swinging input” classic console-style inductor EQ, using a second discrete op amp for gain and a custom-wound steel core Cinemag output transformer.  48V phantom power is available in mic mode and is disabled in line.

As with all Iron Age products, the 622 is as discrete as possible, designed and made in the USA.
