I’m in the process of racking up STUDER 089 modules to use as external preamps. And, I’m in the pleasurable position of having quite a few options (see photo). However, the question is what would be the best combinations? I’d be very grateful for opinions and advice to inform my choices.
I’m using prepared frames by Kid Broadcast, in Germany with their Advocis PSU installed. The racks will have 2 channels, comprised of input units and where available master units/line cards to give a balanced +4dB output (and add more STUDER vibe).
Here are the options I have:
INPUT-UNIT 1.090.015 – I can’t find any info about these boys. I’m guessing they are the first edition MKI units. Their serial numbers are low (in the hundreds) and they have a small BEYER input transformer. It looks as though there’s an extra, chunky inductor in the filter/equalizer circuit (see photos).
INPUT-UNIT 1.090.016 – These are the more common MKI units. The serial numbers are in the thousands and they have the bigger 1.090.001 input transformer.
The front panel controls of these two types of unit are identical and they use three A101 op amp boards each.
INPUT-UNIT 1.090.018 – MKII input units with slightly more filtering/EQ options (4 aux sends that I'll not use), 1.022.305 input transformer and compact discrete op-amps.
MASTER UNIT 1.090.200-01 – I can’t find any info about these either. Low serial numbers with a small BEYER input transformer and what looks like a 1.090.002 output transformer.
MASTER UNIT 1.090.203-01 – With the bigger 1.090.001 input transformer and 1.090.002 output transformers (see photo for comparison of master units).
DAUL LINE AMP 1.091.036 – From MKII aux outputs
KID BROADCAST DUAL BALANCING AMP – brand new
Any ideas which combinations, if any would work better than others, given I can only afford to do a couple of racks right now? It would be nice to have a rack best suited to doing a vintage vibe thing for the DAW 2TK output, and another as a dual channel mic pre.
