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 buttons to first blink, 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.)

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 – 46 dB) and at most 5 dB less (50 dB – 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 fast blinking Input 3 button (53 dB – 51 dB) and at most and at most 6 dB less (55 dB – 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 2 dB less than the steadily-lit Input 2 button (59 dB - 57 dB).

•On switcher with 32 input buttons, the buttons’ volume indications 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.
