Dirac Live upgrade

The miniDSP Flex can be upgraded to run stereo (two-channel) Dirac Live® room correction. This requires an additional purchase for the Dirac Live license. You can either purchase the miniDSP Flex with Dirac Live already activated, or purchase the Dirac Live upgrade at a later time from our webshop:

Note that the upgrade applies per device.

If you do not already have a miniDSP UMIK-1 or UMIK-2 microphone, you can add one to your order when purchasing the Dirac Live upgrade.

Typical applications

The miniDSP Flex has a wide range of applications in home and professional audio. This section illustrates a few of them.

Figure 1 shows the miniDSP Flex used as a digital preamp with subwoofer integration. The Flex provides accurate and flexible integration between the subwoofers and the main speakers as well as comprehensive EQ and tuning options. This is a very cost-effective way to build a complete audio system that includes all the benefits of modern DSP technology. Add the optional Dirac Live software upgrade for world-class room correction.

Figure 2 illustrates a similar use of the miniDSP Flex as a digital preamp, but the output channels have instead been configured to act as crossover for a pair of active 2-way speakers. Amplification can be via a multichannel power amplifier as shown, or a pair of stereo amplifiers.

In Figure 3, the miniDSP Flex has been used as an accessory in a home theater system, to manage multiple subwoofers. Driven from the A/V receiver's subwoofer output, the miniDSP Flex can be used to independently adjust gain, delay and parametric EQ of each subwoofer for optimum multi-sub performance.
