PURPOSE:To provide a displaying device which shows an output level and a reference level of a mixing console. CONSTITUTION:A bar graph meter 28 to 100 segments turns on the 20th lower segment to show a reference level set with the data having level 0 and also shows the data 0 with lighting of 1 segment. When the output level shows -30dB, the lower 10 segments are all turned on. Then all segments up to the 30th segment are turned on with the output level equal to -10dB. When the output level exceeds the reference level, the reference level is also turned on. Therefore it is allowed to display only the segment of the reference level with inversion and with no lighting in order to facilitate the identification of the reference level. In such a constitution, both the output and reference levels can be shown by a single meter 28 and therefore the identification of both levels is facilitated and the hardware structure is simplified. |
