what is sony auto room eq called in avr

2 min read 24-12-2024

Sony's AV receivers and soundbars don't use a single, universally named "Auto Room EQ." Instead, they employ different technologies depending on the model and year of manufacture. The most common names you'll encounter are Digital Cinema Auto Calibration (DCAC) and Digital Reality Creation (DRC). These systems perform similar functions—analyzing your room's acoustics and adjusting the audio output to compensate—but with slight variations.

Understanding Sony's Room Correction Technologies

Let's break down the key differences and similarities:

Digital Cinema Auto Calibration (DCAC)

DCAC is a more sophisticated room correction system. It typically uses a supplied microphone to measure your room's response at multiple points. Based on this data, it automatically adjusts various audio parameters, including:

Speaker levels: Balances the output of your speakers for consistent volume across all channels.
Frequency response: Corrects for peaks and dips in your room's frequency response, leading to a more balanced sound.
Delay: Compensates for differences in the distances between your listening position and each speaker.

DCAC aims to create a more accurate and immersive listening experience, closely replicating the intended sound signature of the source material. You'll find this system in many higher-end Sony AV receivers.

Digital Reality Creation (DRC)

DRC is a simpler form of room correction. While it doesn't usually require an external microphone, its adjustments are generally less precise than DCAC. It analyzes the sound signal itself to make adjustments rather than measuring your room. This usually means it focuses on aspects like:

Dynamic range compression: This can help to prevent overly loud or quiet passages in your audio.
Bass enhancement: This can compensate for a lack of bass response in some rooms.

DRC is primarily found in more budget-friendly Sony AV receivers and soundbars. While it offers some improvement in sound quality, it won't provide the same level of accuracy as DCAC.

Which System Do You Have?

The best way to know which system (if any) your specific Sony AV receiver or soundbar uses is to:

Check the user manual: Your manual will clearly state the room correction technology (if any) available.
Examine the on-screen menu: Look for options related to "Room Calibration," "Auto Setup," or "Speaker Setup." The exact wording will vary depending on the model.

Other Relevant Settings

Beyond DCAC and DRC, you might also see options like:

Speaker Size Calibration: This lets you tell your receiver the size of your speakers (small, large). This influences how low frequencies are handled.
Subwoofer Level Adjustment: This setting allows manual control over the output level of your subwoofer.
Manual EQ: Some Sony receivers offer manual equalization controls for further fine-tuning the sound to your preferences.

Optimizing Your Sony Audio Setup

Regardless of whether your Sony system uses DCAC, DRC, or neither, you can further enhance your listening experience by:

Speaker Placement: Proper speaker placement is crucial for optimal sound. Consult your user manual or online resources for recommendations.
Room Treatment: Acoustic treatments like bass traps and diffusers can significantly improve your room's acoustics.
Calibration Process: Follow the on-screen instructions carefully when running any automatic calibration system.

By understanding the differences between Sony's room correction technologies and making informed choices about your audio setup, you can significantly enhance your home theater experience.
