Note: An effects unit may be inserted between the X-Over Outputs and the
Effects Return Jacks. For instance, it is a popular practice to insert a
Chorus unit between the Hi X-Over Output and the Left Stereo Effects
Return, so that only the high frequencies are chorused while the low
frequencies remain tight and dry. In this manner, the player can get the
desired special effect without "muddying up" his/her tone.
