The “Iron Ore” is the new backbone for all “Iron Projects, a high grade impedance converter and signal balancing concept. With the “Iron Ore” PCB you can build anything from a single channel direct injection box up to 16 channels in a double 19″ unit, and pretty much anything in between! The “Iron Ore” was derived from the “Iron One”, Eli-Audio’s previous direct injection design.

A single PCB can hold up to two channels of high grade direct injection using a variation of Di-transformers. Buy combining multiple enclosures fixed to a custom front-panel more channels can be built in a single device.

Direct Box Transformer Options:

• Lundahl LL1935 with a typical frequency response of +0dB/-2dB from 10Hz up to 45kHz!
• The Jensen JT_DB_EPC, also used by Radial in their JDI.
• Cinemags CM-DBXPC
• Pikatron ÜP3096M microphone transformer, wired in reverse
