USB Audio Volume Controller

The JinTaoRui AM-U002Material is a USB-connected rotary knob that adjusts system volume and provides a one-touch mute function. A metal shell and an ALPS rotary shaft with 30 detents per revolution give a tactile feel, while a breathing LED indicates night mode after eight seconds of holding the knob. It draws power directly from the USB port and requires no driver installation on supported systems.

Desktop Users Needing Tactile Volume Control

This suits anyone who wants a physical volume dial on a Windows, Mac, Android or legacy XP/Vista machine without reaching for on-screen sliders or keyboard shortcuts. The 2 m cable allows flexible placement on a desk or podium. It is not for buyers who need a wireless volume remote, a device with dedicated balance or tone controls, or a solution that works without an available USB-A port or OTG adapter.

Metal Build With 2 Metre Cable

The aluminium-alloy housing measures 5.5 cm by 5.5 cm by 4.4 cm and weighs approximately 200 g, while the fixed USB cable extends 2 metres for reach across a workstation. The ALPS shaft rotates 360 degrees with 30 anchor points per turn, enabling precise increments and infinite rotation. These physical specs determine whether the knob fits the available desk space and meets the durability expectation.

Questions about this item

Does the metal-shell version with the 2 m cable suit a desktop setup better than a smaller plastic one would?

The aluminium shell and 2 m cable let you place the knob on a desk away from the tower while the 200 g weight keeps it from sliding when you turn it.

What does the 30 anchor points per revolution mean when I am adjusting volume in a game?

Each click moves the system volume by one thirty-sixth of a full turn, giving fine control without the jumps you get on smooth encoders.

Is the USB connection limited to USB 2.0 speeds or does it need a faster port?

The device only sends HID volume and mute commands, so any standard USB-A port from USB 1.1 onward works without bandwidth limits.
