Reading the displayed volume
This section is a detailed look at reading the output volume display on the 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
For each display scheme, the input buttons 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. From 5.5% on, each Esc (>) push applies 1.5% more of the input audio signal to the output:
•Push Esc (>) button again — 5.5% + 1.5% = 7% volume
•Switchers with 12 and 16 input buttons — The Input 1 button blinks slowly
•Switchers with 32 input buttons — The Input 1 button lights steadily
•Push Esc (>) button twice more — 7% + 1.5% + 1.5% = 10% volume
•Switchers with 12 input buttons — The Input 1 button blinks quickly.
•Switchers with 16 input buttons — The Input 1 button lights steadily
•Switchers with 32 input buttons — The Input 1 and Input 2 button light steadily
•Push Esc (>) button 19 times more — 10% + (19 times 1.5%) = 38.5% volume
•Switchers with 12 input buttons — The Input 1 through 4 buttons light steadily.
•Switchers with 16 input buttons — The Input 1 through 5 buttons light steadily and the Input 6 button blinks
•Switchers with 32 input buttons — The Input 1 through Input 11 buttons light steadily and the Input 12 button blinks
When all input buttons are lit for any switcher model, the audio output is 100% of the audio input level.
Another way to view the volume level is to think in terms of the attenuation that is applied to the output. Attenuation reduction is indicated by the lit or blinking input buttons: when fewer input buttons are lit, attenuation is greater (and the volume is quieter).
•At minimum volume, all input buttons are unlit or background illuminated and 76 dB of attenuation is applied to the output. The audio output is effectively muted.
•The first step of volume increase causes the Input 1 button to blink (slowly, in the case of switchers with 12 input buttons) . Attenuation is reduced by 13 dB (63 dB of attenuation is applied to the output).
•The second step of volume increase reduces the attenuation by an additional 1 dB
(62 dB of attenuation is applied to the output). (On switchers with 32 input buttons the
Input 1 button lights steadily.)
•Successive steps of volume increase cause consecutive input buttons to first blink and then light steadily. (On switchers with 32 input buttons, each consecutive button indicates a 1 dB attenuation reduction when blinking and a 2 dB attenuation reduction when lit.)
