Yamaha MS101-4 Powered Monitor Speaker

Features

The de facto standard for compact monitoring in a simple form

The standard model in our range of desktop utility powered monitors, the MS101-4 offers portability in a compact design and simple but comprehensive functions for outstanding usability. The MS101-4 comes with a 3/8-16 threaded female mounting for direct attachment to a Euro microphone stand, and optional accessories can also be added for use in a wide range of applications.

A compact, convenient approach to high-quality monitoring anywhere

Yamaha's smallest powered monitor speaker compatible with both line and mic inputs, the MS101-4 powered monitor speaker offers the flexibility needed for temporary or permanent use in applications requiring simple, compact monitors.

Simple, portable, durable design

With the controls (power switch, volume and tone controls) and the combo jack input on the lower front panel, the MS101-4 is simple and easy to operate.

The sturdy metal grill offers complete protection for the four-inch cone driver, while the rear panel is equipped with one stereo mini and two TRS Phone input connectors, and an AC inlet for excellent portability. The bass reflex port is also located on the rear surface, resulting in a more compact chassis.

The MS101-4 offers a compact, lightweight form that is both portable and durable.
