As the name implies, the Big Mouth speaker makes your starter and cadence the king of the hill. This model is self-powered and ready to accept an XLR or 1/4″ input and output, as well as a line-in that accepts RCA or XLR inputs. Precision dials on the back control panel allow you to boost audio levels on individual inputs, and also tweak the treble and bass.
What’s great about the Big Mouth is that is does great double-duty for non-race-day jobs like clinics, small demonstrations outside the track property, and other cases where you need some boom in the room, but not a full-on PA system.
