Visit NAD Electronics - Dirac website for the most up-to-date information on Dirac for NAD products.
Check for the latest firmware update via:
- The Internet Update on the receiver's display (click here for Internet Update Guidelines) or
- The BluOS Controller App.
Dirac Live is available for NAD firmware version v2.12.9 and later. Internet Update is available on v2.10.9 and newer.
Setup Requirements For Dirac Live Room Correction
- Require an active Internet connection, and connect the receiver and computer to the same network.
- Perform all amplifier setup calibrations on the Dirac-enabled AV Receiver before initiating the Dirac room calibration process. This involves configuring speaker setup, levels, and distances, including the subwoofer.
- When using a MAC, choose a USB Microphone in the main sound settings of macOS before launching the DIRAC software. Missing this step will result in the USB Mic not appearing in DIRAC. Once completed initially, the DIRAC software will consistently detect it.
- Disable virus protection or firewalls that may hinder the NAD Dirac software from discovering the receiver.
- Place the microphone in "free air" with no sources of reflection, using a mini or full-size tripod for optimal results.
- Adjust the Mic gain setting to achieve a background noise level of approximately -24dB in the software, using music or TV volume set to a level suitable for a normal conversation without straining.
- Avoid adjusting the subwoofer levels in the Dirac software; instead, retain the settings configured in both the receiver and sub.
- Ensure the first measurement point is located at the ear level in the primary listening position. This is crucial as all impulse corrections are based on this point, while subsequent measure points serve as room response points. A wider physical distance leads to a broader "sweet spot," whereas a narrower set of measurements results in a smaller sweet spot.
- To delete a measurement that produces an error or is interrupted, click on the location, followed by the "X."
- Save the project at this time, allowing the baseline to be recalled for multiple adjustments without the need to re-measure the room.
- Load multiple curves and settings into the NAD AVR, and recall the slots using the remote control. Ensure that target curves are loaded for each grouping of channels (For example: Fronts, Center, Rear Surround, Subwoofer) before optimizing and loading them into the AVR.
- Include and utilize the NAD RoomFeel EQ target curve for optimal results, as recommended.
- Label curves using the save project function, and they will appear accordingly on the AVR once loaded.
- If you add or remove speakers from your system, you must adjust your AVR setup and then proceed to remeasure the room.
- To delete curve slots, drag the curve to the trash bin on the "Export" page.
