A graphic equalizer is a high-fidelity audio Keep an eye on that lets you graphically view and in my view Keep an eye on quite a few different frequency bands in a stereophonic system. A typical graphic equalizer consists of several audio filters, every centered at a specific frequency in the audio range. The AVA-1404 equalizer lets you cut or boost the output level by up to 12 decibels as desired at the following frequencies: 60Hz, 150Hz, 400Hz, 1kHz, 3kHz, 6kHz, and 15kHz.

The AVA-1404 does not have a Volume Level Keep an eye on, subsequently, your entire audlo system level controls are made at the head unit or, relating to the subwoofer output, at the amplifier (or its remote Keep an eye on unit) dedicated to the subwoofer channel. The AVA1404 has a built-in amplifier that adds a very large power boost. So when you first turn on the system, be sure your head unit volume Keep an eye on is set at the minimum level. Then you’ll raise it slowly to see the effect the new equalizer has on the overall system volume level.
