DBX DriveRack PA2 2x6 PA Loudspeaker Management System - DBXPA2-V

Product Overview

The DBX DriveRack PA2 is a 2x6 PA loudspeaker management system designed for live sound engineers and touring production teams who need automated system optimization in a compact rack-mount format. Featuring AutoEQ with the JBL RTA microphone, built-in AFS feedback suppression, and a configuration wizard, the DriveRack PA2 speaker management processor delivers fast system setup and consistent performance across changing venue environments. A dedicated mobile app for Android, iOS, Mac, and Windows provides wireless and wired remote control via Ethernet, making the PA2 a practical choice for front-of-house engineers managing systems from the mix position. Available at Creation Networks.

Product Description

The DBX DriveRack PA2 integrates every processing function required between the mixing console outputs and power amplifier inputs. Two input channels feed six independently processed output channels, each with crossover filtering, parametric EQ, time alignment delay, and PeakStopPlus limiting to protect transducers during high-output performances. The crossover section supports Butterworth, Bessel, and Linkwitz-Riley filter types across slopes from 6 to 48 dB per octave, and subharmonic synthesis is available to extend low-frequency impact from full-range systems. The PA2 includes a Setup Wizard that walks through loudspeaker preset selection, crossover configuration, gain structure, and limiting in a guided step-by-step process suitable for system operators of varying experience levels. Advanced Feedback Suppression automatically places notch filters at feedback frequencies without interrupting the program, and the AutoEQ function uses pink noise and an RTA microphone to generate a target response curve and apply compensating EQ. The DriveRack PA2 Connect app connects over Ethernet and provides full remote control of all parameters including real-time RTA visualization, preset management, and system-level adjustments without returning to the rack. Factory loudspeaker presets for popular cabinet models reduce setup time at recurring installations. At 2U in a standard 19-inch rack, the PA2 is appropriate for both permanent installed sound and touring applications.

Key Features

• 2x6 Signal Architecture - Two inputs and six independently processed outputs support stereo bi-amp, tri-amp, and quad-amp loudspeaker configurations.
• AutoEQ with RTA Microphone - Automated room equalization using pink noise and a connected RTA mic applies corrective EQ curves for faster system setup.
• Advanced Feedback Suppression (AFS) - Real-time automatic notch filter placement at feedback frequencies without manual intervention.
• DriveRack PA2 Connect App - Full remote control of all parameters via Ethernet on Android, iOS, Mac, and Windows platforms.
• PeakStopPlus Limiting - Per-output transducer protection limits peak signal levels to prevent driver damage during high-SPL events.
• Crossover Filtering - Butterworth, Bessel, and Linkwitz-Riley filter types with slopes from 6 to 48 dB/octave.
• Subharmonic Synthesis - Extends perceived low-frequency output from full-range loudspeaker systems without additional subwoofers.
• Setup Wizard - Guided configuration process for loudspeaker presets, crossover points, gain structure, and limiting.
• Factory Loudspeaker Presets - Pre-configured crossover, EQ, and limiting settings for popular cabinet models from major manufacturers.
• Ethernet Connectivity - Wired network control allows remote system adjustment from the mix position or any network-connected device.

Typical Applications

• Live music venue
• House of worship

Frequently Asked Questions

Does the DriveRack PA2 require the DBX RTA microphone for AutoEQ?

The AutoEQ function uses a measurement microphone and pink noise to analyze the room response and apply corrective EQ. DBX recommends the RTA-M reference microphone for this process. Any calibrated measurement microphone with a flat response can be used, but the factory AutoEQ routine is calibrated for the RTA-M.

What platforms does the DriveRack PA2 Connect app support?

The DriveRack PA2 Connect app is available for Android, iOS, Mac, and Windows. It connects to the PA2 via Ethernet and provides full remote control of all system parameters including EQ, crossover, limiting, delay, and preset recall.

Can the DriveRack PA2 be used for permanent installed sound as well as touring?

Yes. The Ethernet control, factory loudspeaker presets, AFS feedback suppression, and Setup Wizard make the PA2 appropriate for both touring production and permanent installed sound environments including houses of worship, auditoriums, and live music venues.

How does the AFS feedback suppression work during a live performance?

The AFS system monitors the signal in real time and automatically places narrow notch filters at frequencies where feedback is detected. The filters engage transparently without interrupting the program signal, and the PA2 can hold up to 12 fixed filters per input channel for recurring feedback frequencies at a given installation.

What is the maximum number of outputs the DriveRack PA2 supports?

The DriveRack PA2 has six output channels, allowing stereo bi-amp (2x2), stereo tri-amp (2x3), stereo with mono sub, or full stereo quad-amp configurations depending on the loudspeaker system requirements.

Does the DriveRack PA2 include a limiter for each output?

Yes. Each of the six output channels includes PeakStopPlus limiting, which provides a hard ceiling on peak signal levels to protect transducers. Limiter thresholds are configured per output during the Setup Wizard or manually via the front panel or app.
