Know before you buy
The Blue Velvet series is specifically engineered for high-fidelity audio, offering superior tracking accuracy between the two channels. This ensures that your left and right audio signals remain perfectly balanced, even at lower volume levels.
Yes, the design is versatile enough to accommodate both installation methods. The six silver-plated lugs provide reliable connection points for either direct soldering in point-to-point builds or mounting onto a PCB.
An audio taper is designed to mimic the way the human ear perceives sound. It provides a smooth, natural increase in volume as you turn the knob, preventing the sudden jumps in loudness often found with linear taper controls.
Yes, the potentiometer features a solid aluminum 6mm shaft, which is the industry standard for most high-quality audio knobs. It is compatible with any knob designed for a 6mm smooth shaft.
Yes, the package includes the required mounting hardware. It uses a metric M8 x 0.75 thread, so ensure your chassis or front panel is drilled to accommodate this size.
