Page 7: Product Overview
YPICAL SYSTEM CONFIGURATION The nanoAVR DL typically connects between an HDMI source such as a Blu-ray player and an A/V receiver or processor. Two HDMI sources can be connected to the nanoAVR DL. Audio from the selected HDMI input is processed by the Dirac Live®... -
Page 8: How Dirac Live® Works
Computer connectivity is used to perform acoustic measurements and generate digital room correction filters for Dirac Live®. Up to four sets of correction filters can be stored on the NanoAVR DL processor and recalled from the front panel, via an infrared remote, or with the miniDSP smartphone app. Once the processor is fully configured, the computer is no longer needed. - Page 9 Late reflections are left largely untouched, being corrected only for their spectral coloration, as they contribute to a larger, more enveloping soundstage. miniDSP Ltd, Hong Kong / www.minidsp.com / Features and specifications subject to change without prior notice...

Page 10: Nanoavr Dl / Dirac Live® Configuration Steps
AVR DL / D IRAC CONFIGURATION STEPS The steps for configuring the NanoAVR DL HDMI audio processor with Dirac Live® to optimize your home theater system is summarized as follows: Connect the NanoAVR DL audio processor into your system and install software. -
Page 11: Installation And Setup
The Dirac Live Calibration Tool is used to perform measurements, generate correction filters, and load them into the nanoAVR DL. You will find it under the heading “nanoAVR Dirac Live Tools” in the nanoAVR section of the User Downloads on minidsp.com. -
Page 12: License Activation
2.1.3 License activation Start the miniDSP NanoAVR DL Utility program. It will appear as shown on the left below. Connect your NanoAVR DL processor to your computer via USB, then click on the Connect button. It will change to a green tick. -
Page 13: License Validation
Dirac server using the form shown at left in step 4 above. If you purchase more than one NanoAVR DL or Dirac Series processor, each will need to be activated with its unique serial number. Use the form shown on the right in step 4 above and enter the serial number of each additional processor, and they will in turn be added to your license. -

HDMI outputs. The nanoAVR DL does not decode compressed formats such as Dolby and DTS. † Apple Macs with a Thunderbolt port can be connected to the nanoAVR DL with the use of a Thunderbolt to HDMI adapter cable. -
Page 15: Dc Power
To configure the nanoAVR DL using Dirac Live Calibration Tool for miniDSP: Connect the USB port of the nanoAVR DL to a USB 2.0 port on your computer using the supplied cable. Connect a miniDSP UMIK-1 to a second USB port on your computer using the supplied cable. -
Page 16: Acoustic Measurement
COUSTIC EASUREMENT The Dirac Live Calibration Tool For miniDSP uses a set of measurements made in your listening room to gather all the acoustical information about your room and speakers that it needs to calculate the correction filters. The measurements are made using the NanoAVR DL HDMI audio processor and a miniDSP UMIK-1 measurement microphone (must be purchased separately). -
Page 17: Connections For Acoustic Measurement
HDMI connections are needed. Simply: Connect the supplied USB (type A to type B) cable from the nanoAVR DL to a USB port on the computer. Connect the supplied USB (type A to mini type B) cable from the UMIK-1 to a USB port on the computer. -
Page 18: Configuring For Measurement
ONFIGURING FOR MEASUREMENT Start Dirac Live Calibration Tool For miniDSP. Ensure that no other programs are running that may attempt to communicate with the nanoAVR DL, such as the nanoAVR DL utility program, as this may result in communication conflicts and errors. -
Page 19: Sound System Tab
7.1 will be selected. Test signal playback device Preset to nanoAVR DL. This will ensure that test signals are sent into your audio system via the NanoAVR DL processor. If the nanoAVR DL is not showing, check that your NanoAVR DL processor is connected via USB and powered on, click the Rescan button, and then use the drop-down menu to select nanoAVR Once you have verified that this tab is correct, click the Proceed button. -
Page 20: Mic Config Tab
It is in the form xxx-yyyy and labelled on the microphone. Ensure that you download both the regular calibration file and the “90-degree” calibration file. (The latter is generated specifically for use with the nanoAVR DL.) Then click on the Load file button and select your calibration file. -
Page 21: Output & Levels Tab
On the Output & Levels tab, set Output volume quite low. If you have another volume control “down-stream” of the nanoAVR DL, set it about halfway (or -20 dB if digital) and increase it later if needed. Set the HDMI input to a connected and powered-on source device. Then click on the Test button for the left channel and gradually increase the output volume until it is at a moderate level, such that your voice would have to be raised to converse with someone sitting next to you. -
