D.____ 200 milliseconds

17. If a singer says he wants "more echo" on his voice, you would adjust the_______ on the effects processor.
A.______ chorus
B.______ harmonizer
C.______ delay and feedback
D.______ flange

18. The left side of a sound system is not working. However, the signal LED's on the power amplifier are lighting up. Possible cause could be:

C.______ equalizer not connected properly
D.______ loose amplifier banana connector

19. Speaker polarity can be tested using a:

B.______ 24x4
C.______ 24x8
D.______ 16x16

21. If you bring down a channel fader on a mixer, the levels on all the pre-fade aux sends will:
