This BBE 422A Sonic Maximizer is a dual-channel rackmount audio processor that uses phase correction to improve audio clarity, definition, and punch by realigning time-delayed frequencies. This unit is great for augmenting your live or studio sound, whether you are using it with guitars, keyboards or vocals. This processor splits the signal into three bands (lows, mids, highs) and applies subtle delays, controllable by “Lo-contour” (bass EQ) and “Definition” (highs) knobs per channel.
This used rack-mountable unit has some faded graphics on the front panel and obvious wear on the t op of the housing, but is graded very good condition overall.
