Reading the displayed volume

NThis section is a detailed look at reading the output volume display on the matrix switcher’s front panel. If you do not need to read the exact value of the volume setting, skip this section.

There are 65 steps of volume attenuation, with 1 dB per step (button push), except for 0-to-1, which is 35 dB. At maximum attenuation, no input LEDs are lit, 98 dB of attenuation is applied, and the audio output is effectively muted. At no attenuation, all input LEDs are lit and the output volume is equal to the input signal plus any gain or attenuation that is applied to that specific input using the input audio level adjustment. See Viewing and adjusting the input audio level, on page 3-24 See the table at right to read the volume display.

The input LEDs blink or light sequentially to indicate the approximate volume of the selected output. Volume is defined as a percentage of the input audio signal that is applied to the output. From 0% of volume, the first Esc (>) button push applies 5.5% of the input audio signal and causes the Input 1 LED to blink slowly. From 5.5% on, each Esc (>) push applies 1.5% more of the input audio signal to the output:

Push Esc (>) button —

5.5% + 1.5% = 7% volume. The Input 1 LED continues blinking slowly.

Push Esc (>) button twice — 7% + 1.5% + 1.5% = 10% volume. The Input 1 LED begins to blink quickly.

Push Esc (>) button 19 times —

10% + (19•1.5%) = 38.5% volume. The Input 1 through 4 LEDs light steadily.
