Smart Acoustic SPM120

The Smart Acoustic SPM120 is a small, battery-powered device that helps performers or speakers hear themselves more clearly through earphones or in-ear monitors.

What It Does:

• It lets you connect your earphones or in-ear monitors to a sound system.

• You can control your own volume using the dial on the unit.

• It’s perfect for musicians, presenters, or performers who need to hear themselves without relying on stage speakers.

Key Features

• Works with most equipment: You can plug in using a standard microphone cable (XLR) or guitar-style cable (1/4” jack).

• Headphone output: Plug your earphones into the small headphone port (1/8” or 3.5mm jack).

• Mono or Stereo switch:

  • Set to Mono if you’re getting sound from a single channel (like a mixer’s aux send).

  • Set to Stereo if you’re using it with a headphone output that plays two channels (left and right).

• Easy on/off and volume control: Turn the volume knob all the way down to power it off.

• Power: Runs on two AAA batteries – portable and easy to carry.

Ideal For:

• Musicians on stage using in-ear monitors

• Public speakers or presenters who want to hear themselves clearly

• Small setups where personal sound control is important
