Stellavox ALP8 pinouts?

[rstl99]

Hi,
I just acquired a Stellavox ALP8 external mic preamp that's meant to plug into the Stellavox recorder through a cable.  I don't own a Stellavox recorder.

 

The ALP8 allows connecting two microphones and has a single 6 pin socket in the back (OUT), for both powering the preamp from the recorder, and feeding the mic signals to the recorder.

I plan on using this mic preamp, which I assume is of excellent quality given the Stellavox origins, with other recorders, analog and digital.

But I don't know how to wire a proper cable and what each of the 6 individual pins represent signal wise. I assume two are for power and ground, and that means 2 each for each of the two mic signals.

If anyone knows of the pinouts, please enlighten me. Otherwise, I'll need to take the cover off the ALP8 and try to reverse engineer the pinouts via the circuit boards inside.

The attached pic is from ALP8 online, showing the 6 connector cable (which I don't have).

Thanks,
Robert

P.s. here are the technical specs on the ALP8 if you are curious, they were made to be fitted to the Stellavox SP8 recorder:

 

ALP-8
LINE PREAMPLIFIER. The ALP 8 adds to the multiple possibilities of the tape recorder Sp 8 by changing the two adjustable <line>-inputs into <microphone>-inputs, which puts up the number of separately adjustable microphones to four. Each way includes a switch <music-speech> and a three position selector providing, in addition to the dynamic circuit, the supply of phantom 12 V or phantom 48 V (option with converter) and parallel 12 V. An internal bridge allows 0, -10 or -20 dB attenuation for the gain of the condenser microphones. The ALP 8 is simply connected between the microphone cables (it is available for Cannon male, Cannon female or Tuchel cables) and the <AUX> plug of the Sp 8 by a special cable (code: CMA).

TECHNICAL SPECIFICATIONS:
gain: 42 dB, distortion: < 0,05%, supply: 1 5 to 25 V DC, weight: 0,6 kg, dimensions: 3,5x12x15 cm3,
response: 20 to 20000 Hz ± 1 dB, bass cut: 12 dB/oct. below 100 Hz, power drain: approx. 8 mA
