The Motor Box is a metal-geared, high-speed, digital servo motor with an adjustable Attachment Coupler, built-in mounting bolt, and a clamping nut. It is powered from the foot controller with a standard 3.5mm TRS (stereo) cable. The Attachment Coupler connects to a potentiometer shaft, and the Motor Box attaches to a mounting bracket with the mounting bolt and the clamping nut. All attachments and adjustments can be made without using any tools.

The Attachment Coupler has a brass insert, and a stainless steel set screw with a knurled plastic thumbscrew head. It is spring-loaded so that the position of the indicator arrow can be adjusted by pulling, turning, and releasing the coupler into a new position.

Includes 2mm hex wrench (for tightening the Attachment Coupler’s retention screw).

The 3.5mm TRS (stereo) Connection Cable is not included.
