Thank you for your purchase of an Iron Age Mic Pre (QPP). Iron Age Audioworks is a small 
team of engineers and designers and we truly appreciate your business. We hope you enjoy 
using this as much as we enjoyed making it. 

Safety 

Safety with audio equipment is normally a matter of common sense, but we want to make sure 
you get the best use out of your equipment. So please, use common sense including... 

Use typical practices for using electrical and audio equipment. 

Don’t clean this with water or use it around water.  

Any ventilation openings in the case need to remain open.  

Don’t use this around anything that’s hot (such as a radiator or space heater).  

Don’t defeat the ground pin on the plug or use a ground-lift device that does. 

Don’t use a cut or damaged power cord, and keep the cord from getting pinched or 
stepped on. 

Don’t service the box unless you’re a qualified technician. 

Power  

The unit is powered by an internal linear power supply and will accept standard 110 VAC 
power. A user-accessible fuse is located on the IEC connector at the rear of the case. It will 
come set at +/-22V and +48V for phantom power.  Please contact us if you would like to 
change the supply voltage for use with other op amps.
