Operation, cont’d
When all input LEDs are lit, 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 less).
•At minimum volume, all input LEDs are unlit and 98 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. Attenuation is reduced by 35 dB (63 dB of attenuation is applied to the output). There is no change in the volume indication.
•The second step of volume increase reduces the attenuation by an additional 1 dB (62 dB of attenuation is applied to the output). The front panel display is unchanged.
•Successive steps of volume increase cause consecutive input LEDs to first blink slowly, then quickly, and then light steadily.
For example: When lit steadily, the Input 3 LED indicates 47 dB of attenuation when compared to the Input 3 LED blinking quickly (48 dB to 50 dB of attenuation). The blinking Input 4 LED (45 dB to 46 dB of attenuation) is at least 2 dB less than the fast blinking Input 3 LED (48 dB – 46 dB) and at most 5 dB less (50 dB – 45 dB).
