- Transformer Microphone Preamp.
- Iron is the 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 trim pot gain range has been limited from +20 to +60 dB to allow fine level control.
- To allow for lower input level boost, we added a 20dB [Range] switch, so the range can be changed to be 0 to +40 dB, keeping the same fine 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 High-Pass-Filter (Lo-Cut-Filter) from the EQ section of the Ark console.
