Our different FAB Modules come in different standard sizes (2.0 x 2.5, 2.0 x 3.0″, etc…), and sometimes you may want to keep all your Modules equal in length when laid side by side in (2) columns.  Some cases where I see this is if you want your XLR Input and Output Modules aligned at the same offset, so you can mount them on your chosen case.

This utility module is a simple “extender” module, whose sole function is to add some extra length space to your modules. It’s just a direct pass-through, as you can see from the PCB traces in the diagram below. That is all, nothing special, nothing extraordinary…. but could be useful in certain cases.

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, typically used in Neve preamps.

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.

Updated the Wiki Documentation page for our FAB2000 Series Modules.

All FABModules related to the Input Section. These will include XLR Female jacks, TRS jacks, Input Transformers, Balanced Line Receivers, Mic Input Modules, Returns, DI (High-Z) inputs, etc

• FAB2010 – XLR Input Module
• FAB2110 – Input Transformer Module

I did a quick test just to see if all the FAB Modules work and play well together.  I’m very pleased with the results…. The modules were quiet, and even with a long signal chain as you can see in the picture, there was hardly any noise I could hear.  (For testing, I hooked up a condenser microphone and connected the outputs to a KRK RP8 8″ Monitors. No humming, no RF noise, nothing.)

Everything works… the logic control Phantom Power, -20dB Pad, Polarity Reverse, and the +6dB Boost (1:2 Transformer Ratio).  To get the FAB4312 Non-Inverting Amplifier working, I hooked up a small 10K potentiometer so I can adjust gain.  For now, I just used a jumper and connected the Phantom Power Logic control inputs directly to a spare V+ terminal on the FAB1215 PSU module.

Mouser.com put a crinkle on my plans when I learned that one of the part I need for my FAB1215 is out of stock. There’s (22) pcs on order, but they won’t become available until May…. so all in all, it’s not looking good… Mouser may just stop carrying this part suddenly.  I emailed them asking about their future plans for this part, whether they’ll be continuing to carry it or not.
