Anechoic Chambers (38 suppliers)
Audio Amplifiers and Preamplifiers (385 suppliers)
Audio amplifiers and audio preamplifiers are used to increase the amplitude of sound signals. Preamplifiers or preamps are designed to amplify low-level signal from a high-impedance device such as a microphone or instrument pick-up. After pre-amplification, the signal is sent to a power amplifier or amp, which provides the higher current necessary to drive the speakers.

Audio Cables (294 suppliers)
Audio cables transmit audible signals such as voice and music. They are designed to minimize noise and interference that can impair sound quality. Audio cables connect an audio source such as a stereo or microphone to an audio receiver or output such as speakers. Most products are shielded to prevent electromagnetic interference (EMI), typically with a foil and/or braided shield.

Headsets (281 suppliers)
Headsets are designed to hold earphones to a user’s head for radio or telephone communications. They include transducers and a transmitter, and are designed to receive audible signals from a source such as a portable media player or audio amplifier. Often, headsets are bundled with microphones for two-way communication. The main benefit of headsets is that they let users listen privately, and make it easier to hear in noisy environments.
