Memphis Audio SBT4

The Memphis Audio SBT4 is a Bluetooth audio controller with AUX input and USB streaming/charging for marine and powersports installations. A rotary control knob operates the system, and its colored illumination indicates the selected source.

The controller provides a 3.5 mm main output, a 3.5 mm AUX input and an amplifier turn-on output. It supports flush, surface or bar mounting, with a separate control box that can be mounted out of sight. Memphis describes the unit as water and element resistant.

Plan a suitable mounting location, protected cable routing and connections to compatible audio equipment. Confirm connector requirements and source-device support before installation.
