Jensen designed mic pre modules and EQ modules
Posted: Tue May 10, 2011 8:13 pmSo I happen to have a stash of Jensen designed mic pre modules and EQ modules. I bought a bunch for a project and these are my left overs.
The Mic pre's feature a JE110k-hpc input tx, a single signetics 5534 and a small LED meter showing signal -30db, -10db and +10db. Fairly straightforward design and the specs of the transformer are excellent.
The Eq's are a swept, 3 band design based around 3x TL075cn jfet opamp with dual concentric pots and 2x signetics 5534 output stage. These sound excellent and I purchased my first pair from indigo ranch studios some years back and they have sat in my rack sweetening various things ever since. It was one of my first rack jobs and it was pretty easy though I did have it checked over by Joe Malone who laughed at my wiring...
I have schematics for the mic pres but none for the eq's but I do have pinouts and if you really want to know the circuit it would be pretty straightforward to trace. The output should drive a 600 ohm transformer and I have some of those available too though they are not jensen ones.
So the modules are available for 150 per pair of mic pres and 300 per pair of eqs. Pm me if you are interested...
