miniDSPFlexEight

Product Overview

The miniDSPFlexEight is a stereo-input, eight-channel output compact high-resolution audio processor. It features

two digital inputs, USB audio, Bluetooth streaming with LDAC™ and aptX™ HD codecs and automatic Bluetooth input

selection, and an OLED front panel with physical volume control.

DiracLive upgrade

The miniDSPFlexEight 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Eight 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:

Convert to Flex Eight (DL)

Note that the upgrade applies per device.

Typical application

The miniDSPFlexEight is ideal for compact active loudspeaker solutions. Any outputs that are not used for the

speaker can be used for independent subwoofers.

Figure 1 shows the miniDSPFlexEight used as an active crossover with two subwoofers integrated. With multiple

digital inputs including Bluetooth audio streaming, this is very cost-effective way to build a modern active speaker

system. Add the optional DiracLive software upgrade for world-class room correction.

subwoofers.
