The Yamaha Silent Brass System allows the performer to play their instrument without disturbing those around them. The system includes a set of mini-headphones, a practice mute (redesigned for 2014), and a Personal Studio amplifier module (also redesigned for 2014). The player plugs the mute and the headphones into the module and then plays. A microphone in the mute picks up the player's own sound and sends it to the amplifier where it is "filled in" and sent to the headphones. This third generation system features Brass Resonance Modeling for an even more realistic sound. Features:
