The Flex family There are several versions of the 2-in 4-out miniDSP Flex with different I/O con gurations. Refer to the Flex product page (https://www.minidsp.com/products/minidsp-in-a-box/ ex) for the complete list.

  • Page 6: Typical Applications

    Note that the upgrade applies per device. 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 exible integration between the subwoofers and the main speakers as well as comprehensive EQ and tuning options.
  • Page 7 Figure 1. miniDSP Flex as preamp with subwoofer integration Figure 2 illustrates a similar use of the miniDSP Flex as a digital preamp, but the output channels have instead been con gured to act as crossover for a pair of active 2-way speakers. Ampli cation can be via a multichannel power ampli er as shown, or a pair of stereo ampli ers.
  • Page 8 Figure 2. miniDSP Flex as preamp and active crossover 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.
