2ch balanced line inputs converting line levels to Eurorack levels.

From top:

channel A
input 1/4″ jack (balanced line level)
gain knob
output 1/8″ jack (modular level)
4-LED level meter (-20/-6/0/+3dB or +6dB – jumper selectable)

channel B
4-LED level meter (-20/-6/0/+3dB or +6dB – jumper selectable)
input 1/4″ jack (balanced line level)
gain knob
output 1/8″ jack (modular level)

On board settings (see picture):
– ground lift jumpers for balanced inputs (jumper header set = grounded, removed = gnd lift)
– jumper for last LED indicating +3dB or +6dB level (jumper header set = +3dB, removed = +6dB – nearly overload),
– jumper for dot/bar meter mode (jumper header set = dot mode, removed = bar mode)
– meter calibration trimmers

Frequency range: 15Hz to 60kHz (-1dB),  10Hz to 80kHz (-3dB)
Max. gain: +26dB (20x)
Max. input level: 4V p-p
THD+N: better than 0,02%
Input impedance: 100kOhm, AC coupled

Width: 4TE/ 4HP/ 20mm
Depth: 62mm /2,5″ max.
Current: 70mA max. in bar mode, 50mA max. in dot mode
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.
