For sound quality and safety, choose the Sound Alert 10 Position Jack Box. Hearing loss is a serious issue for students, and this jackbox has red and green LED indicator lights: green is a visual reassurance that the jackbox is powered on, red when the audio levels exceed 85 decibels, the volume at which students are at risk for hearing damage. Light enough to be portable, this jack box also has predrilled holes for permanent mounting.
Features strain-relief connectors that ensure its cord won’t be pulled out, no matter how enthusiastic your students. The permanently attached cord has 1/4" and 3.5mm plugs so it's compatible with all media players.
The silver-plated contact points for a solid connection without the startling "crackling" sound heard when connecting with other jackboxes. Includes individual volume controls at each input so students can select the sound they need. Constructed of rugged ABS plastic housing for durability and the skid-resistant pads on the bottom keep it from moving without marring or scratching table surfaces.
