The Abyss Devices MTR is a simple 2hp volume meter with a unique, almost tree-like design and features a rainbow of LEDs that can show signals from 0v up to +12v. A trimmer on the front can be adjusted to fine tune the voltage range and how it's spread across the 12 LEDS. High impedance buffered input and outputs gives you a clean throughput. Add some lights to your rack and monitor your signal with the MTR.
