Features:

With input power options ranging from 6W to 100W (model-dependent), these devices accommodate various audio setups. The line input is 100V, with attenuation per step at 3dB and total attenuation at 33dB. The volume controls have 10 positions plus an off switch. They offer both flush and surface mounting options, constructed from polycarbonate (PC) with a white finish.

Operating in transformer-based control mode, the signal input and output range from 70-100V, suitable for voltage speakers. The frequency response is 80Hz-16KHz, with 11 steps for precise adjustment. Dimensions vary slightly by model, with weights ranging from 0.14Kg to 0.22Kg. Each volume control comes with a pair of M4 x 25 screws for convenient installation.
