With the push of a button, you can humorously signal "Right Answer" or "Wrong Answer" with a Bing or a Buzz. Alternatively, play a brief musical interlude before announcing a winner or when giving students time to think of an answer. It also has volume control and an on/off switch to save your batteries.
This versatile little gadget is PLENTY loud all on its own, but if you want even louder -- for really large classroom use -- just gather some external speakers (not included) and plug them into the sound box's audio output jack and you'll be able to amplify all the sounds in a BIIIIIG way.
This simple tool gives you bells and whistles without costing an arm and a leg! Weighs only 1/2 pound. Dimensions: 6" X3.5". 3 AA Batteries included.
