1HP Passive Attenuator
1HP passive attenuator
Two independent thumbwheel potentiometers in as narrow a module as possible.
Currently offered with 10k ohm linear mono potentiometers
The small size makes it more suitable for occasional level adjustments, rather than frequent on-the-fly adjustments.
Two of these modules can only be placed directly next to each other if the plugs you use are less than 5mm in diameter (most aren't).
Part of the 1HP family from Redux Kits.
