Appendix C - Volume Attenuation Table
Overview
Volume attenuation on the DVX-2150 and 2155 is not set by percentage like it was on earlier DVX models: On the
DVX-2150 and 2155 models, the output volume slider changes .5dB per click, to provide a more subtle adjustment.
Unity gain is at 88, so a setting of 100 is actually 6dB gain. A setting of 20 would be -34 reduction
(88-20=68 clicks. @ .5dB per click =34 dB). This is only the output slider.
