For example: When lit steadily, the Input 3 button indicates the following, depending
on the number of input buttons the switcher has:
• Switchers with 12 input buttons — 47 dB of attenuation when compared to the
Input 3 button blinking quickly (48 dB to 50 dB of attenuation).
The blinking Input 4 button (45 dB to 46 dB of attenuation) is at least 2 dB less
than the fast blinking Input 3 button (48 dB minus 46 dB) and at most 5 dB less
(50 dB minus 45 dB).
•
Switchers with 16 input buttons — 52 dB of attenuation when compared to the
Input 3 button blinking (53 dB to 55 dB of attenuation). The blinking Input 4 button
(49 dB to 51 dB of attenuation) is at least 2 dB less than the blinking Input 3 button
(53 dB minus 51 dB) and at most 6 dB less (55 dB minus 49 dB).
• Switchers with 32 input buttons — 58 dB of attenuation when compared to the
Input 3 button blinking (59 dB of attenuation). The blinking Input 4 button (57 dB
of attenuation) is 6 dB less than the steadily-lit Input 2 button (60 dB minus 57 dB).
• On switcher with 32 input buttons, the volume indications of the buttons are
additive.
For example: Input 1 lit (23 dB [22 dB + 1 dB] of attenuation reduction), Input
2 lit (2 dB [1 dB + 1 dB] of attenuation reduction), and Input 3 blinking (1 dB of
attenuation reduction) indicate that the output attenuation has been reduced by a
total of 25 dB (22 dB + 2 dB + 1 dB = 25 dB).
• At full volume, no attenuation is applied to the output and all input buttons are lit
steadily.
Example 10: Viewing and adjusting a local output volume level
In the following example, the audio output volume is viewed and adjusted. The steps show
the front panel indications that result from your action.
Because of the different volume display schemes, the output audio levels that result from the
following example are shown three times:
• As displayed on a 32-input button switcher
• As displayed on a on 16-input button switcher
• As displayed on a 8-input button switchers
The 32-button drawings show the actions that led up to the display. 16-button and 8-button
drawings show the volume display only, not the actions that caused it.
1. Clear all selections: Press and release the Esc button.
2. Select Audio mode: Pr ess and hold the Audio button for approximately 2 seconds
until it blinks.
