Reading the displayed value

This section is a detailed look at reading the output volume display on the 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 22dB. At maximum attenuation, no input LEDs are lit, 85 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 (HVA models)”. Other than the minimum and maximum volume, the switchers indicate the volume differently, depending on number (12 or 16) of input LEDs. See the table on the next page to read the volume display for each display scheme.

For each display scheme, 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. 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

All switcher input button configurations — Indicated by the Input 1 button blinking slowly.

•Push Esc () button twice — 7% + 1.5% + 1.5% = 10% volume

Switchers with 12 input buttons — Indicated by the Input 1 button blinking quickly.

Switchers with 16 input buttons — Indicated by the Input 1 button lit steadily.

•Push Esc () button nineteen times — 10% + (19•1.5%) = 38.5% volume

Switchers with 12 input buttons — Indicated by the Input 1 through 4 buttons lit steadily.

Switchers with 16 input buttons — Indicated by the Input 1 through 5 buttons lit steadily and the Input 6 button blinking.

When all input LEDs 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 LEDs: when fewer input LEDs are lit, attenuation is greater (and the volume is quieter).

•At minimum volume, all input LEDs are unlit and 85 dB of attenuation is applied to the output. The audio output is effectively muted.

•The first step of volume increase causes the Input 1 LED to blink (slowly, in the case of switchers with 12 input buttons). Attenuation is reduced by 22 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).

•Successive steps of volume increase cause consecutive LEDs to first blink, then light steadily.
