Ayre QA-9 Owner's Manual download pdf (Page 14)

It is recommended to set the audio

level prior to recording by playing a

loud passage from the analog source.

Adjust the QA-9 gain so that the peaks

occasionally illuminate the amber

LEDs but not the red clipping LED.

If the red clipping indicator LED(s)

illuminate during recording, it is

recommended to restart the recording

with reduced levels.

Signal level metering is usually provided in the

recording hardware or software, but the QA-9

front panel level meters provide the most

accurate insight into the actual analog-to-digital

conversion.

Display

The 3-digit numeric display indicates the current

sample rate (e.g., “192”) for the active output.

Vertical bar-graph LEDs on either side of the

display indicate the digital signal level being

generated by each channel of the QA-9.
