can anyone suggest the best way to connect the La-2a to a Mackie 32x8 for vocals? I'm running with a Avalon ad2022 mic preamp. should i run the mic to the Avalon then out of the Avalon to the in of La-2a then out of La-2a to mackie? and also where should i plug it thru the line in or thru the insert or XLR jack on the mackie? your input is greatly appreciated thanks in advance.
