Transformer Microphone Preamp

Iron is the Octa / 500 module version of the much loved Mic Pre of the Ark console, but with our custom input transformer.

For pure sonic clarity, Iron’s universal amp can accept signals from any type of microphone whatsoever.
Even older Ribbon microphones, synths or guitars can be directly connected without a problem (so yes, you can also use this mic input as a line input).

The Mic input trim pot has a gain range of 40 dB to allow fine level control.
To allow for higher input levels, we added a 20dB [Range] switch, which lowers the input level but keeps the same fine level control of the input signal.

Note that the [Range] switch is not a “Pad”, but changes the gain range of the microphone amplifier by modifying the following parameters:
- the value of the gain pot
- the quiescent current of the input stage
- the amount of feedback used to stabilise the circuit accordingly
All of these are necessary to preserve the exemplary noise, distortion and headroom performance at all gains.
In short: While a “pad” and our “range” have a similar effect, a “pad” adds noise to the circuit, our [Range] switch does not.

Iron also features our reference bargraph meter and the Lo-Cut-Filter (also called High-Pass-Filter) from the EQ section of the Ark console.

Iron is available as Octa or 500 module with “Silver” or “Black” faceplate
