Delta Loudspeakers has been dedicated to visualization of audio signals since 1992. Till date many instruments have been intensively used and misused. In order to acquire consistent information from data visualization & acquisition instruments, it is very important to understand how sound waves travel in space and interact with the ambient. The Neutrik - Cortex NC10-2A is a very powerful tool we frequently use when visiting our customers. It is an authentic problem solver! This instrument has the ability to operate with two channels simultaneously. It also measures transmission loss in real time. When it comes to precise measurements, such as sound pressure levels or spectral analysis, the NC10-2A is unsurpassed in precision and post processing capabilities via PC communication software.
