A graphic equalizer is a vital component of a stereo sound system. It is used to regulate the frequencies of audio signals to achieve higher sound quality. To control these sound frequencies, it needs to operate with an amplifier or stereo receiver. Learning how to connect equalizer to integrated amplifier is relatively simple.
Equalizers are available in a wide range of features and prices, but they all have one objective, and that is to adjust the sound at different frequencies. You don’t need a professional to hook up an equalizer to an amplifier. In fact, it involves a straightforward process that can be done in a few minutes.
For the signal to flow from a stereo receiver through the graphic equalizer up to the amplifier, you need two sets of RCA cables. These are the same cables required to attach auxiliary components such as CD players, DVD players, and other record players. These cables must be of the same length as the distance between the equalizer and receiver.
Most receivers are integrated with a preamp in and preamp out connections, while some consist of tape monitor attachments. Connecting the equalizer to the preamp out or preamp in connections is more advisable than to the tape monitor. The main reason is that the tape monitor does not connect to the amplifier.
Use one set of RCA cables to connect the receiver and the equalizer. Attach one pair to the preamp out ports and the other end to the right and left preamp in ports. All these channels are found on the back side of the graphic equalizer.
The technique in this step is that the colors correspond to the RCA plugs. For example, the white plug connects to the white jack; the red plug connects to the red jack, and so on.
Next, use the second pair of the RCA cables to join the amplifier and the receiver. Attach each jack to their corresponding color in the device’s plugs.
After connecting the RCA cables, you can now join the amp to the receiver. It is done by attaching the RCA cables in the amplifier inputs on the receiver.
This set-up creates a loop from the receiver through the equalizer and the amplifier then back to the receiver. As a result, all three units are connected.
Now that you have the three units connected, test the equalizer. Turn each unit on. Try adjusting the sound by rotating some of the equalizer knobs. You should be able to achieve fine-tuned music based on your preferences.
Use the knobs to modify the frequency levels or tone of the music easily.
Some receivers don’t have the appropriate output plugs to join an amplifier and an equalizer. In this circumstance, it is possible to connect the equalizer straight to the amp. Few simple considerations can be done to achieve it.
Attach the two sets of RCA cables from the equalizer to the amplifier. Connect each jack to the corresponding color of the port. The cables should be long enough to fill the gap between the two units. Locate the preamp in and preamp out at the back of each unit.
Connect one pair of the cables to the preamp output port on the amplifier and the rear end to the preamp input port on the equalizer. Then, work with the other pair. Attach the cable from the output port on the equalizer to the input port on the amplifier.
This procedure should be straightforward as you only need to connect the jacks to their corresponding color on each unit.
Switch the amplifier and equalizer on to check if the connection is correct. Rotate the equalizer knobs to test if they are working correctly and modify the audio according to your preference.
A preamp is a device that processes signals from audio components, then passes them to a powered amplifier of the speaker system. Sometimes, equalizers are connected to a preamp so that the user can manipulate the sound across a wide range of audio frequencies. Hooking it up to an equalizer is straightforward.
Insert the plug on one end of the audio cables into the “Out to EQ” jack on the rear portion of the preamp. Do it by utilizing the red plug for the right audio jack and white plug for the left audio jack.
Attach the plugs on the other end to the preamp jacks labeled “EQ loop”. Use the same color-codes to match the jacks with the plugs.
Connect the second set of audio cables from the “out to amplifier” jacks of the preamp to the input ports of the power amplifier. Then, attach the electrical cords on the components to a surge protector. Plug it to a power outlet.
After successfully connecting your equalizer to the amplifier, the acoustics is now better. Make some little adjustments to the frequency levels so that you can make it sound exactly the way your ears like it.
Some units have integrated EQ controls, also known as the stereo audio equalizer, to help adjust the particular sets of frequency bands. The EQ controls provide several pre-set selections, such as rock, flat, pop, concert, electronic, vocals, jazz, folk, acoustic, and more. This is the easiest and convenient way to adjust the frequencies right at your fingertips.
Take note that the sound quality and listening to music are a subjective experience. From casual listeners to devoted audiophiles, people tend to have specific preferences. To achieve sound quality that is good enough for most listeners, use the EQ controls.
Before you can touch the knobs or controls of the equalizer, position the speakers in a manner that they sound best. Set the controls to zero or neutrals to bring them back to the original, untouched settings. Make small adjustments to the controls depending on your own judgment or preferences.
Learning how to connect equalizer to integrated amplifier is relatively easy. Sometimes, you do it with common sense especially the color-coding scheme of the jacks and plugs. Once you’ve successfully connected the units, you can maximize your audio system to satisfy your listening experience.
