In physics, a closely related quantity called  optical depth  is used instead of absorbance: the natural logarithm of the ratio of incident to transmitted radiant power through a material. The optical depth equals the absorbance times ln(10).The term absorption refers to the physical process of absorbing light, while absorbance does not always measure absorption: it measures attenuation (of transmitted radiant power).he optical depth equals the absorbance times ln(10).

(1) Analog mixers. Analog mixers adjust the volume and tone of input audio signals. Most of the control knobs and faders are arranged on the top panel, so it is easy to understand the signal flow and what state the audio is in.Operating analog mixers is normally an intuitive process.or example, when using a mixer with a band, at least eight channels for input may be required for microphones to pick up the sound of the whole drum kit. In this case, a model that is equipped with enough channels that are compatible with microphones should be chosen.
