EQ4® Operation Notes & Product Warranty Model: EQ4-500 www.maagaudio.com Operation Notes Because of the Maag Audio EQ4’s unique design, phase shift is very minimal. This helps the user maintain the integrity of the original sound and enhance the “Airy” frequencies, while tonally shaping the sound from the top to the bottom. The lack of phase shift and the AIR BAND® make the EQ4® great on anything that needs EQ shaping. The EQ4’s band passes all interact with each other.
