Abstract
A gated multi-channel amplifier system comprises a plurality of musical performance amplification channel means each responsive only to high threshold level sound input for producing amplified sound output, and another channel comprising a vocal/announcer amplifier channel means capable of responding to announcer sound input of both low threshold level and high threshold level for producing an amplified announcer sound output, and means for gating the vocal/announcer amplification channel means to respond to announcer sound input of low threshold signal level only in the absence of response by the other musical performance amplification channel means.
