Playing "Call The Shots" by Slynk from the YouTube Audio Library
Top PP-31 is the Left audio channel connected to the pre-amp RCA Left output.
Bottom PP-31 is the Right audio channel connected to the pre-amp RCA Right output.
VU Meters are connected to the pre-amp XLR Stereo outputs.
The real Spectrum Analyzers colors are much more like the green from the McIntosh logo below. Also 30fps is not enough to capture how quick and sensitive the 2 devices really are. I tried taking a video at 60fp but the LEDs would start flickering on camera when you can't see it from naked eyes.
