Grammy Award–winning engineer Tom Young is currently working with Tony Bennett; he was also the longtime live mixer for Frank Sinatra.
One of the most powerful — yet underused — tools in mixing with digital consoles is the use of delays. From the setup, delaying the P.A. to stage monitors or to the backline tightens the mix. Also, for effect I sometimes mult various inputs within the band and use 2 to 3 milliseconds of delay on various instruments during solos to bring out the instrument and pan the delayed signal. With the ease of setting up scenes for solos and multing inputs in the scene — say three inputs for a rack tom or overhead on a drum kit — this will make the instrument jump out without bringing up the fader.
