Typical applications¶
Figure 1 shows the miniDSP 2x4 HD used as a digital preamp with subwoofer integration. The 2x4 HD provides accurate and flexible integration between the subwoofers and the main speakers as well as comprehensive EQ and tuning options. Add the optional Dirac Live software upgrade for world-class room correction.
Figure 2 illustrates a similar use of the miniDSP 2x4 HD as a digital preamp, but but the output channels have 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 2x4 HD 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 2x4 HD can be used to independently adjust gain, delay and parametric EQ of each subwoofer for optimum multi-sub performance.
Dirac Live upgrade¶
The miniDSP 2x4 HD 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 2x4 HD with Dirac Live already activated, or purchase the Dirac Live upgrade at a later time from within the Device Console. Refer to the instructions here:
Note that the upgrade applies per device.
