Turn on all of the devices in your sound system. Turn off
any auto-equalizers on your sound system to gain fullest control over
frequencies. This switch might be found on the receiver or the equalizer
Play a test song on repeat. Choose a song with both
extremely high and extremely low instruments so that you have a wide frequency
range to listen for.
Listen for any obvious distortions in the highs and lows
of the songs. Lower the knob on your equalizer for any distorted frequencies
until the distortion disappears. Try at first to find the highest setting
possible without distortion.
Adjust all frequency ranges in relation to each other to
find a pleasing blend for your room, trying not to let any one frequency range
dominate the others. Use the highest non-distorting settings found in Step 3 as
maximum settings, but don't be afraid to lower a booming bass or a screeching
flute that disrupts the overall blend of the music.
Play a song from a different genre to test how the EQ
works for different types of music. A hip hop song will have louder lows than a
string quartet, for example, so make sure your bass frequencies sound crisp on
both types of music.
