API Mic Pre 500 series from 312 card

API Mic Pre 500 series from 312 card

An API 312 card can be mounted into a 500 series size module chassis and outfitted with necessary controls to be a fully functional professional mic pre. 

This Mod came about from customer’s requests to make something useful from 312 cards they had sitting on a back shelf collecting dust.

The Drawbacks  :

1. Not much you can do with a 312 as is, except keep as a spare for your API console.

The Solution :

Mount the 312 card into a sub chassis so it can plug into a 500 series rack. Include the following controls:

1.  -20 db input pad.
2. Phase reverse switch.
3. Phantom power switch.
4. Gain Pot

Price is for modification labor and parts.  Does not include unit to be modified.
