Monitoring audio and VU sensitivity

Applies to: Pearl-2, Pearl Mini, Pearl Nexus, Pearl Nano

You can connect headphones to the 3.5 mm audio jack on the front panel of the device. The audio you hear depends on which layout is currently live because different layouts can have different audio sources configured.

A VU meter shows the audio levels for the channel. The value is displayed in dBFS (decibels relative to full scale). Colored bars represent the audio level.

Audio VU meter levels

| Color | Decibel range | | Red | 0 to -9 dBFS | | Yellow | -9 to -18 dBFS | | Green | -18 dBFS and lower |
