World's Best Classroom Amplifier Systems
We accept all major credit cards

Traditionally an aid for hearing-impaired students, amplifiers are increasingly being used in regular classes, mostly at the kindergarten to third-grade level. Kids at that age often have ear infections, which can limit hearing for up to two months. They also often have trouble distinguishing between sounds and concentrating because of background noises and classroom reverberations. When there’s a lot of noise in a classroom, children have a hard time filtering what’s important to listen to and what’s not. When a teacher has an amplification, they know what to focus on. With the Newton classroom amplifier, no child can escape the voice of the teacher. The Newton amplifies a teacher’s voice by about 10 to 20 decibels, which is loud enough for students no matter where they are seated, but not so loud that neighboring classrooms can hear it. The average adult human conversational voice is about 60 decibels or about 1 Watt. A 6 W amplifier would sound like 6 people talking at the same time. We introduce this line of excellent products because we saw a growing need for classroom amplifiers and there are not too many alternatives on the market except the cumbersome H-Fi amplifiers with all the wiring and external speakers or the portable Karaoke systems that does not provide good true voice reproduction. All those devices are subject to loud feedback from the microphone. Newton Amplifier Systems are manufactured by an award-winning factory in Taiwan. We re-designed their classroom amplifiers for use in United States. They all have received the necessary FCC, CE, and UL certifications. The factory is ISO-9001 and ISO 14001 certified. The electronics are all made of high quality and reliable Surface Mounted Devices (SMD). Xtreme Gadget has obtained exclusive marketing rights for the Newton Amplifier Systems.
