QP5 Mic Pre
The Iron Age 500 series mic preamp was designed as a utility front end solution. The mic preamp is the most important part of your signal chain, and this preamp gives the detail and depth your signal deserves. You get classic transformer-coupled mic preamplification with unmatched tone and flexibility at an absolutely unbeatable price.
Each QP5 features an all-discrete, transformer balanced input and output mic pre with a flexible and powerful topology that offers up to 80 dB of gain! The QP5 uses the same preamplifier as our QPP rack mount units, packed with additional useful features.
The unit uses a Jensen input transformer and a custom-wound steel core Cinemag output transformer, selectable for 1:2 or 1:3 ratio.
The first op amp works as a preamplifier, with adjustable gain of up to 40 dB.
We took the rumble filter from our CS1 channel strip, followed by the same discrete transistor buffer we use in the CS1 and the V2 equalizer.
A second op amp is fed by a trim control, and a “high gain” switch adds 12 dB more if needed.
A bank of -20 dB pad, polarity, and 48V phantom power switches round out the feature set.
The QP5 uses our original M2 discrete operational amplifier, designed and built by us.
