Fantastic digital stereo sound from the installation-free Juno® tower with Bluetooth® — great for both voice and media amplification. The three-speaker 2.1 line array (two mid-range HF drivers and one woofer) provide full, rich stereo sound, with volume level easily controllable via voice command. For voice amplification, Juno lets you use up to five microphones simultaneously through the optional Channel Expansion Module. Meanwhile, the next-generation Adapto™ digital engine actively scans audio 375 times per second to suppress feedback squeal before it starts. Juno features our patented OptiVoice™ technology to emphasize critical speech sounds, so kids comprehend even more.
