Cry6151 Electroacoustic Analysis System

1 CRY6151 adopts a 4-channel data acquisition system, which can achieve the testing of 2 headphones and 2 microphone components in the same instrument.

2 Its hardware includes a sound card module, power amplifier module, signal processing module, and USB communication module. It is combined with software to perform various electroacoustic device tests.

3 Its chassis design and simple USB 2.0 interface for data transfer can meet customers' various test environment requirements.
