A-525 2ch preamp + 2ch line out/pad module for conversion between line levels and Eurorack levels for Eurorack / Doepfer A100 system.

Gain is settable by internal jumpers:
preamp section – jumper in front position = +12dB (4x), jumper in rear position = +20dB (10x)
Input impedance 100kOhm, AC coupled, frequency range (-3dB points) 15Hz – 30kHz, low noise design.
out/pad section – jumper in front position = -10dB (/3), jumper in rear position = -20dB (/10)
Input impedance 10kOhm, DC coupled, passive dividers

For line equipment with weak line levels (home audio) set jumpers to rear positions, for professional line levels use front jumper positions.

Width: 4TE/ 4HP/ 20mm
Depth: 32mm /1,3″ max.
Current: 10mA
Power cable included

Double check power connection before powering your system please.
„Red strip“ means -12V connector side in Eurorack standards.
In some power distribution systems connector key can be reverted.
In this case cut connector key and plug power connector right way (with respect to red strip) or use different power cable appropriate to your power system.
