Preparing for Calibration
Before you start calibrating your home theater speakers, there are a few things you need to do to prepare:
Gather the Necessary Equipment
To calibrate your home theater speakers, you will need a few pieces of equipment, including:
- A sound level meter: This is a device that measures the sound pressure level (SPL) of your speakers. You can purchase a sound level meter at most electronics stores or online.
- A calibration DVD or Blu-ray disc: This is a disc that contains a series of test tones and calibration signals that will help you adjust your speakers. There are several calibration discs available, including the popular “Avia II” and “Digital Video Essentials” discs.
- A remote control: You will need a remote control to adjust the settings on your receiver or amplifier.
Position Your Speakers Correctly
Before you start calibrating your speakers, make sure they are positioned correctly. Here are a few tips to keep in mind:
- Place your front left and right speakers at ear level: This will help to create a more immersive soundstage and improve dialogue clarity.
- Position your center channel speaker below or above your TV: This will help to improve dialogue clarity and create a more cohesive soundstage.
- Place your surround speakers at ear level or slightly above: This will help to create a more immersive soundfield and improve the overall sense of envelopment.
Calibrating Your Speakers
Now that you have prepared your equipment and positioned your speakers correctly, it’s time to start calibrating. Here’s a step-by-step guide to help you get started:
Step 1: Set the Volume
The first step in calibrating your speakers is to set the volume. To do this, play a test tone from your calibration disc and adjust the volume until the sound level meter reads 75 decibels (dB). This is a good starting point for most home theater systems.
Step 2: Adjust the Speaker Levels
Once you have set the volume, it’s time to adjust the speaker levels. To do this, play a test tone from your calibration disc and adjust the level of each speaker until it reads 75 dB on the sound level meter. Start with the front left and right speakers, then move on to the center channel speaker, and finally the surround speakers.
Step 3: Adjust the Subwoofer Level
The subwoofer is a critical component of any home theater system, and adjusting its level correctly is essential for good bass response. To adjust the subwoofer level, play a test tone from your calibration disc and adjust the level until it reads 75 dB on the sound level meter.
Step 4: Adjust the Crossover Frequency
The crossover frequency is the point at which the subwoofer takes over from the main speakers. To adjust the crossover frequency, play a test tone from your calibration disc and adjust the frequency until you find the point at which the subwoofer starts to dominate the sound.
Advanced Calibration Techniques
Once you have completed the basic calibration steps, you may want to consider using some advanced calibration techniques to further optimize your home theater system. Here are a few techniques you can try:
Room Equalization
Room equalization is the process of adjusting the frequency response of your speakers to compensate for the acoustics of your room. To do this, you will need to use a room equalization system, such as the Audyssey MultEQ system.
Speaker Distance Calibration
Speaker distance calibration is the process of adjusting the delay settings on your receiver or amplifier to compensate for the distance between your speakers and your listening position. To do this, you will need to use a speaker distance calibration system, such as the Onkyo’s AccuReflex system.
