1. Bass Control Function of the Preamplifier

• If you turn on the tone control on the front of the product and turn the bass knob to the left or right, the bass range is increased or attenuated (in

100 ㎐ increments), as shown in the figure below.

• It can be adjusted from -15 ㏈ (attenuation) to +15 ㏈ (increase) in 100 ㎐/0 ㏈ increments.
