Level / Gain Adjustment Range
Gain Adjustment Range is the span of level adjustment available at an active crossover’s specified input or output, expressed in decibels.
The limits show how far the signal can be attenuated or boosted relative to the stated reference. Keep the location of the control and any step size with the value. A range is different from a fixed gain figure or a yes/no indication that adjustment exists.
Level / Gain Adjustment Range — Crossover
Use the range to judge whether the crossover can accommodate the relative levels needed by the source, amplifiers and driver bands. Input trim and output trim act at different places in the signal path, so identical ranges need not have the same practical effect.
Boosting level uses headroom and can cause clipping if the next stage’s limits are exceeded. The range does not establish maximum clean output voltage or available amplifier power. Compare the stated endpoints, reference and control location rather than treating the largest adjustment range as inherently better.
