The Yamaha QL1 comes armed with Dan Dugan Sound Design’s revolutionary automatic microphone mixing technology. This remarkable processor, which can be loaded into up to 16 channels simultaneously, lets you automatically optimize your microphone gain distribution for speech applications. The result is smooth, natural gain control — the QL1 almost mixes itself! This is a lifesaver for a non-engineer volunteer who runs live sound in a house of worship or at a community event. This is especially useful in non-scripted situations, as it allows you to concentrate on the balance rather than having to chase talkers on the faders.
