ARCHIVE 6 ARCHIVE 5

Racking channel strips and other "vintage" units is one of Pro Harmonic's specialist services. Beyond simply putting modules into a case, the units are optimised for standalone operation, refurbished and modified for the best possible performance whilst retaining the unit's unique qualities.

The archives contain past examples of equipment racking - delving back into history

european line amp modules - cranked for mic pre gain

two transformers and five transistors, it couldn't be anymore simple ..... and hard pressed to sound much better!

Harrison
the last of the Harrison Channel racking project! ( please, no more! ) Two pairs of transformer mic-pre versions ( blue EQ knobs ) and two pairs of transformerless versions. These things must have the most powerful sweepable high and low pass filters of any console EQ ever made!

balanced I/O and makeup gain added

AWA BIG-1
two sets of Big 1 Pairs. Normally just a single unit is a rack space, I got a shoehorn out and levered two units into the one case. Attack and Release added. Fat Australian made hard FET limiting
