Yamaha SB39 Silent Brass System for French Horn
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

Improved sound
The sound from this "next generation" system has been greatly improved over the previous generation. The hiss has been greatly reduced, allowing players to hear more of their sound and less noise.

Simplified controls and sleeker look
The new module has only a volume knob and an echo switch, eliminating the unneeded extra features and making it even more affordable.

Aux In jack
One of the things carried over from the previous generation is the Aux In jack. This 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.

Input jack
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.

Output/phones jack
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.
