The DriveRack PA2 is the small-system version of dbx's loudspeaker management, aimed at a band or a house of worship running mains and subs from a single rack. Two XLR line inputs feed six XLR line outputs, and the setup wizard walks through speaker selection, crossover, and room tuning rather than expecting the operator to already know the numbers.

The input chain carries compression, Advanced Feedback Suppression, graphic and parametric EQ, and subharmonic synthesis; the output chain has crossovers, parametric EQ, limiting, and driver alignment delay of 10 ms per channel. A dedicated RTA microphone input with +15 VDC powering drives AutoEQ. Everything is controlled from an Android, iOS, Mac, or Windows app over Ethernet. Conversion runs at 48 kHz with 112 dB A-weighted dynamic range and 0.003% THD+N, in a 1U chassis weighing 5.25 lbs.
