Isolators are included in the test set up as with the component testing. [10] The combined test signal can be injected directly in to the receiver if the antenna is removable. A second directional coupler, connected in the conventional configuration, can be used to provide a feed of the input to a spectrum analyser.
The send jack can always be counted on to send signal out to an external devices. A refinement of the normalization of jacks is the presence on the mixer of an insert control which, when adjusted, allows the user to patch into or around the inserted devices at will without having to physically disconnect the insert cables.
An audio analyzer is a test and measurement instrument used to objectively quantify the audio performance of electronic and electro-acoustical devices. Audio quality metrics cover a wide variety of parameters, including level, gain, noise, harmonic and intermodulation distortion, frequency response, relative phase of signals, interchannel crosstalk, and more.
A typical sound reinforcement system consists of; input transducers (e.g., microphones), which convert sound energy such as a person singing into an electric signal, signal processors which alter the signal characteristics (e.g., equalizers that adjust the bass and treble, compressors that reduce signal peaks, etc.), amplifiers, which produce a ...

NTi Audio AG is a manufacturer of test and measurement instruments for acoustics, audio and vibration applications. With headquarters in Schaan, Liechtenstein, the company specializes in end-of-line audio testing for manufacturing quality control purposes, [1] provides instruments for testing public address systems in safety-critical environments [2] and also produces handheld Audio Analyzers ...
Sound-on-film is a class of sound film processes where the sound accompanying a picture is recorded on photographic film, usually, but not always, the same strip of film carrying the picture. Sound-on-film processes can either record an analog sound track or digital sound track, and may record the signal either optically or magnetically .
In balanced audio systems, there are equal and opposite signals (difference-mode) in inputs, and any interference imposed on both leads will be subtracted, canceling out that interference (i.e., the common-mode). CMRR is a measure of a system's ability to ignore such interference and especially hum at its input.
