The redesigned Silent Brass module is smaller than a cassette tape and weighs about as much. It fits easily into a shirt pocket and can be attached to the player's belt, if desired. This makes the new Silent Brass systems much more portable and convenient. The sound from this "next generation" system has been greatly improved over the previous generation. The "hiss" has been greatly reduced, allowing the player to hear more of himself and less noise. The module has only a volume knob and an echo switch, eliminating the unneeded extra features. The aux in jack allows an external sound source to be combined with the signal coming from the mute or microphone. The player can then play along with their favorite song in practice and performance settings and put the fun back in their practice sessions. The input jack allows a quick and easy connection to a Yamaha pickup mute for practice or to a Yamaha MC-7 instrument mic for performance. The Output/phones jack allows the Silent Brass system to be connected to earphones for private practice, an external sound system for sound reproduction, or to a recording system for recording.
