GAIN CONTROLS-
The Gain controls are located on the rear panel to minimize
control tampering after installation. When viewing the amplifier
from the rear, they are on the left end, top and bottom, as shown
in the illustration to the right.
The Gain controls are detented (11 steps) for repeatable
adjustment. Surrounding the Gain control, the power attenua-
tion level is shown in dB. To operate the Gain control, rotate the
control’s knob so that the desired level is achieved. There is a
detent in the knob to indicate its position.
Maximum gain depends on the model, see chart, below.
