Manual firmware instructions are available (see attached)
Setup Requirements For Dirac Live LE
- An active Internet connection is required.
- The T758V3 and the computer must be connected to the same network.
- All speaker setup calibrations MUST be done on the Dirac enabled AV Receiver before beginning the Dirac room calibration process. This includes speaker setup, levels and distances, including the subwoofer.
- When using a MAC, you must select USB Microphone in the main sound settings of the MacOS before launching the DIRAC software. If this step is missed, the USB Mic never appears in DIRAC. After this is completed once, the DIRAC software will always be able to see it.
- Turn off virus protection, or firewalls that might prevent the T758 from being discovered by the NAD Dirac software.
- The Microphone should be in “free air” with no sources of reflection, a mini or full size tripod works great.
- Set the Mic gain setting just high enough that background noise level is about -24dB in the software (you can use music or TV volume set to a volume that a normal conversational can be had without straining)
- Do not adjust the subwoofer levels in the Dirac software, leave the settings you set in the NAD T758 & Sub.
- The first measurement point is vital, ensure it is in the primary listening position, at ear level - All impulse corrections are based on this point, all the following measure points are room response points, a wider physical distance will result in a wider “sweet spot”, a narrow set of measurements will make for a smaller sweet spot.
- If a measurement produces an error, or is interrupted, you can delete that measurement by clicking on the location, followed by the “X”.
- It’s a good idea to save the project at this time. This baseline can be then recalled for multiple adjustments without re-measuring the room.
- You can load multiple curves and settings into the NAD AVR, and recall the slots via the remote control. Target curves must be loaded for each grouping of channels ( e.g. Fronts, Center, Rear Surround, Subwoofer) before optimizing and loading into AVR.
- We have included the NAD RoomFeel EQ target curve, and recommend that you use it for best results.
- Curves can be named via the save project function, and will appear as so on the AVR once loaded.
- If you add or remove speakers from your system, you will need to change your AVR setup, and then remeasure the room.
- Deleting curve slots is done by dragging the curve to the trash bin on the “Export” page.
