dbx DriveRack PA2 — Complete Loudspeaker Management System

The dbx DriveRack PA2 positions itself between mixer and amplifiers, equipping you with all necessary tools to optimize and protect your loudspeaker system. Designed for touring bands, mobile DJs, and installed venues, this compact 1U unit merges a 2-in/6-out DSP platform with advanced AutoEQ and AFS algorithms exclusive to dbx. Users seeking a processor that manages crossover, EQ, compression, limiting, and feedback control will find this model indispensable.

What Stands Out in the DriveRack PA2

Utilizing an RTA microphone, the refined AutoEQ algorithm analyzes the room and configures speaker levels and EQ in seconds, sparing the need for prolonged pink noise sweeps. Feedback is caught before it reaches the audience thanks to the improved AFS algorithm, which adjusts outputs preemptively. Integrating dbx Type IV A/D conversion and a 100 ms input delay for aligning delay towers, this device brings processing depth typically reserved for larger touring systems.

Inputs, Outputs, and Signal Flow

With a 2-in/6-out structure, this model accommodates full-range, 2-way, and 3-way speaker setups from a single processor. Electronically balanced XLR connections with RF filtering help maintain signal integrity even across long cable runs.

• Inputs: 2 × Female XLR line + 1 × Female XLR RTA mic — electronically balanced, RF filtered, >50 kΩ impedance
• Outputs: 6 × Male XLR — electronically balanced, 120 Ω impedance, +20 dBu max output
• The system utilizes a 48 kHz sample rate with dbx Type IV Conversion System

Onboard Processing

Access every part of the signal path, from input compression to output limiting and delay for driver alignment. The 8-band parametric EQ on each output provides dedicated speaker tuning, while dbx compression and subharmonic synthesis enrich the low end as needed.

• Input Processing: dbx Compression, AFS, 31-band Graphic EQ, 8-band Parametric EQ, Subharmonic Synthesis
• Output Processing: Crossover (full range / 2-way / 3-way), 8-band Parametric EQ, dbx Limiting, Driver Alignment Delay
• Per-channel alignment delay of 10 ms (60 ms total) and up to 100 ms input delay are available for flexible system timing

Physical and Electrical Specs
