Alto Professional’s Trouper is a compact high-performance PA system that fulfills the unique demands of solo artists and small ensembles.

The Trouper leverages technology from our widely-acclaimed Truesonic and Black Series sound reinforcement systems to be the best-sounding and most full-featured small-venue PA system available.

When you have more space, the XLR output connects with additional loudspeakers and subwoofers, and Trouper’s wireless Bluetooth capability supports using up to two linked units for stereo backing tracks or background music.

Two XLR+1/4-inch combo inputs, a stereo RCA input and 1/8-inch input can accommodate microphones, instruments, DJ mixers, controllers and more. An integrated audio mixer on the back panel enables volume and low frequency/high frequency EQ control on each of the three channels.

Trouper is a 2-way 200-watt bi-amplified system (130 watts LF/70 watts HF) with three 6.5” woofers and a 1” high-frequency compression driver, spanning the full musical frequency range from 65 to 20,000 Hz.

The system has thermal and dynamic overload protection, so the sound is always clean and clear no matter how hard you push it.
