A karaoke sound system had a mixer that combines the singer's real-time
voice signal from a microphone with the pre-recorded background
song/music signal from a player, an amplifier that receives the mixed
signal from the mixer to provide amplification or gain boosting, a
dedicated channel for the vocal signal from the microphone without using
a mixing device, one or more speakers to output the mixed and amplified
audio signal, and one or more speakers to output the vocal signal from
the dedicated channel. The vocal channel allows the vocals to maintain an
overall cleaner and vibrant sound, with a "live feeling" positional
presence.
