This is similar to our FAB2110 Input Transformer Module… but instead of using a CAN type transformer, we’re using a Carnhill/UK Input Transformer, (model VTB-9045) typically used in Neve preamps.

The VTB-9045 Carnhill Transformer is a Low Level Audio Signal Transformer, with a turns ratio of 1+1:2+2.  DC Coil resistance is 24+24:130+130 ohms.

To mount the Carnhill transformer horizontally on this FAB board, a separate Carnhill PCB Adapter is also required.  Both boards will be provided when you purchase this FAB board.

Here are some photos showing the FAB1215 Power Supply Module powering some FAB modules via a ribbon cable.

Here’s one of the simplest way to use our FABModules….  Hook up the following FABs together:

FAB2010 – XLR Input Module
FAB2110 – Input Transformer Module
FAB3010 – XLR Output Module

All that’s missing is Power, if you want to enable the -20dB Pad, Phantom Power and Polarity Reverse functions. Otherwise, it will still work without power applied. After all, it’s just an input transformer inserted in your signal chain.

Populated our FAB2110 Input Transformer Module with parts.  Here are some photos showing a Jensen JT-11K8-APC Input Transformer mounted on it.

The board looks good, but I’d probably add another mounting hole on the lower right corner, just because the board is a little unstable with a heavy transformer mounted on it.

I’ll build another prototype using a different Input Transformer, like an Altran or EA brand.
