In the world of home theater, high-quality room correction is essential to creating an immersive experience where every sound is perfectly balanced for your space. One of the most widely used and trusted tools for this is Audyssey, integrated into Denon and Marantz AVRs.
Audyssey allows you to adjust audio settings dynamically, accounting for the unique acoustic characteristics of your listening area. While Audyssey is powerful on its own, following a detailed setup checklist is the best way to unlock its full potential and achieve optimal room correction. By integrating these step-by-step tips, you’ll ensure flawless operation of your surround sound system, avoid pitfalls, and improve your overall audio experience.
Before and During Audyssey Setup: Foundation for Superior Room Correction
Audyssey does an excellent job of recalibrating speakers and subwoofers, but to harness its full potential, there are a few key criteria you should follow before and during calibration:
1. Room Treatment and Speaker Placement Are Non-Negotiable
- Room treatment isn’t simply ‘nice-to-have’—it’s essential. Poorly treated rooms can cause inaccurate readings and undesirable sound reflections, which cause Audyssey’s high-frequency correction and Dynamic EQ or Dynamic Volume to underperform. To achieve clean and smooth high-frequency response, focus on reducing hard surface reflections (e.g., walls, windows).
2. Use the Included Microphone—and Check for Faults
- Audyssey calibration microphones are precisely tuned for each receiver model, making substitutions unwise. However, some batches of Audyssey microphones have been known to be faulty. If your results seem inconsistent, test another microphone of the same type from another Denon or Marantz AVR for peace of mind.
3. Proper Microphone Positioning: Avoid Makeshift Devices
For best results, position the microphone using a boom stand or tripod, ensuring a stable setup. Makeshift solutions such as holding the mic or propping it up on furniture may cause inaccuracies in calibration due to movement or misalignment.
4. Use All 8 Microphone Positions
- A close mic pattern with all positions is highly preferable. The more data Audyssey gathers from varied seating positions, the better it can optimize the sound for the entire room. Consider placing the microphone at ear level in each listening area, while avoiding obstacles like chair headrests that may cause unwanted reflections.
5. Minimizing Reflections—A Hidden Factor
- It’s important to reduce reflections from walls, headrests, and other surfaces near the microphone to avoid skewing Audyssey’s frequency adjustments. Keeping the environment as acoustically neutral as possible ensures more accurate room correction.
6. Use the Audyssey App—But Be Cautious with Adjustments
- When using Audyssey’s mobile app, it’s key not to limit correction to just the low frequencies (although tempting for some users). While Audyssey does well balancing bass, its midrange and treble calibration are part of what makes the system effective. Use the reference curve without adjusting the midrange unless you have a specific reason to.
7. Consider External Amplification for Difficult-to-Drive Speakers
- If your system includes 4-ohm or power-hungry speakers, pairing them with external amplification is highly advised. Highly dynamic speakers will work best under these conditions, and you’ll reduce the load on your AVR’s internal amps. If an external amp isn’t immediately available, start by limiting the volume to under -15 dB to prevent overload.
After Audyssey Calibration: Fine-Tuning for Optimal Listening
Once Audyssey setup is complete, fine-tuning becomes key for optimal surround sound performance:
1. Crossover Settings: Stick to 80Hz
Even if your speakers are capable of producing sound below 80Hz, stick to the THX-recommended 80Hz crossover setting. This allows your subwoofer to handle low frequencies more effectively, leaving your speakers to focus on mids and highs, ensuring greater overall clarity.
2. Adjust Dynamic EQ for Balance
- Audyssey’s Dynamic EQ is a must-use feature when playing content at lower volumes. For most material, compensating at 10dB is a good starting point. For cinematic content, set the Reference Level Offset (RLO) to zero. If it feels too aggressive, backing off to RLO 5 can strike a better balance.
3. Dynamic Volume for Day-to-Night Flexibility
- Dynamic Volume plays a key role in ensuring smooth playback at all hours. For reference-level listening, turn it off. For general listening, use Light Mode, and for late-night movie sessions, switch to Evening (Medium) or Night (Heavy) mode, which compresses sharp peaks and boosts quiet passages, ideal for reducing sudden loud sounds without losing detail.
4. Don’t Forget Volume Rebalancing
- When listening below -15dB, turn on Dynamic Volume Day (Light) mode to ensure smoother playback and better balance at moderate volumes.
5. Fine-Tune Surround Speaker Volume
- If audibly, your surrounds seem too prominent, gradually reduce the surround speaker volume by 0.5dB steps and re-test across different content types (movies, TV, music) while also adjusting the RLO for each scenario. You’ll find your sweet spot that blends the surround audio seamlessly into your overall sound environment.
Is It Worth the Effort?
It’s true that following such a detailed Audyssey checklist may seem time-consuming to some, especially if you’re new to optimizing room correction. However, skipping these steps can lead to incomplete calibration, meaning you’re not getting the full benefit of your Denon or Marantz AVR.
Investing this time upfront—using proper microphone placement, managing reflections, and accurately configuring Dynamic EQ and Dynamic Volume—transforms sound quality from good to exceptional. By addressing even minor factors, like controlling speaker distance errors or subwoofer timing, you ensure smooth, immersive audio across all frequency ranges and volumes. Ultimately, for dedicated audiophiles, the payoff in sound clarity is more than worth the effort.
