While not as commonly used as they used to be, equalizers remain a popular option for fine-tuning home-audio systems' frequency response. Using an equalizer properly requires a lot of knowledge of your room specs, but you can easily connect the equalizer to your integrated amp, even if it lacks the Tape Loop function most equalizers depend on.
Figure Out the Chain

Step 1
Figure out the audio chain (how many components you have and how you plan to connect them) in your system. If your only source is a CD or DVD player, or if your integrated amp has preamp-out and preamp-in connections, you can easily make all of the necessary connections.

Step 2
Connect your source component with one pair of RCA cables to the input of the graphic equalizer. Use cables long enough to allow you to place the equalizer in your rack.
Step 3
Connect the output of the equalizer to the preamp input of your integrated amplifier with the second pair of RCA cables.
Step 4
If you'll be connecting multiple components, you'll need an integrated amp with preamp out and in. Connect all components to the appropriate inputs on the integrated amplifier.
Step 5
Connect a pair of RCA cables from the preamp output of your integrated amp to the input on your equalizer. Connect a second pair of RCA cables from the output of your equalizer to the preamp input of your integrated amplifier.
