Hi can a MIC and a CD player as source be connected to the ML3 at the same time, so that a person can talk while music is played from a unbalanced line from cd player?

Frequency Isolator / Remover Utility. ISO3 is a game changer for many tasks such as cutting any range of frequencies (popular in DJs world) without the use of addition filters or EQs. isolating frequency range, and muting vocals/instrument in a particular frequency range. Isolators are crossovers of bands that than sum all the split signals per bandits a final stereo signal.
