INTERMOD EXPLORER

Intermodulation Analysis and Frequency Coordination Software

Intermodulation (IM) or intermodulation distortion (IMD) is the amplitude modulation of signals containing two or more different frequencies, caused by non-linear behaviour of the signal processing (physical equipment) being used. Since practically all audio equipment includes non-linear components, then some degree of IMD is unavoidable.  Intermodulation specifically creates non-harmonic tones due to undesired mixing of near frequencies, and these spurious emissions create minor to severe RF interference to other nearby signals.  

The good news is the physical basis for IMD is well understood and the mathematical formulas used to describe it are relatively simple -- so, computational methods can be applied to generate frequency sets that are free of intermodulation interference and which mitigate its effect.

Intermod Explorer is a new, ground-breaking software tool specifically designed for the wireless proaudio field. Its computational engine rapidly generates frequency sets of intermodulation distortion-free radio frequencies. The frequency sets can be used to coordinate transmitter frequencies where the goal is to assign the most reliable channels to your wireless audio gear.
