1. Inputs - Connect your bass guitar to one of these standard 1/4" unbalanced jacks.
If your bass has passive electronics (that is, if it has no battery), connect it to Input 1, which
is designed to handle low-level signals. If your bass has active electronics (that is, if it has
a battery), connect it to Input 2, which employs a 10 dB pad and is designed to handle
hotter bass pickup signals.
2. Volume control - This is the overall volume control. For best signal-to-noise ratio, keep
the output of your bass at or near maximum and adjust the B Series Volume to the desired
level.
3. Shape control (B60, B90 and B120 only) - This control applies a specialized 20 dB
notch filter to the specified frequency area so that you can customize the effect of the
Shape curve to best complement your particular bass instrument. Moving the Shape
control clockwise causes the notch filter to be applied to higher frequencies while moving it
counterclockwise causes it to be applied to lower frequencies. At the fully clockwise
position, the filter is applied to the 1 kHz frequency area; this will act to attenuate
mid-range frequencies and give your bass a deep, low tone. At the fully counterclockwise
position, the filter is applied to the 90 Hz frequency area; this will act to attenuate low
frequencies and give your bass a biting, trebly sound. For more information, see the
"Using Equalization and Shape" section on page 8 in this manual.
