There are 3 PWM channels which controls RGB led stripes in the inner to show the electronics.
The LED bar can be controlled to display classic VU meter, peak only, VU and peak hold, difference, difference and peak ...
The VU scale is from +6dB down to -32 dB in 2dB steps and showing the last 4 steps in 4 dB steps down to - 48 dB.
The LED's are multiplexed 2000 times per second in 6 groups which is about 166 Hz per LED.
