dbx DriveRack PA2 Crossover / Altifalante

dbx DriveRack PA2 — Complete Loudspeaker Management Between Mixer and Amps

All essential processing stages between your mixer and amplifiers are handled by the dbx DriveRack PA2, which combines crossover, EQ, dynamics, feedback suppression, and delay in a 1U rack chassis. For touring acts, installed venues, and portable rigs, this processor's reworked AutoEQ engine and networked remote control are essential. Sound professionals turn to this model when they need a single unit to optimize and protect loudspeaker systems in any venue.

What Sets the DriveRack PA2 Apart

Inside the chassis, dbx's Type IV A/D Conversion System pushes dynamic range up to 123 dB with transient material, letting live peaks through without converter clipping. Enhanced AFS anticipates feedback, applying surgical notches before the audience hears a squeal, and the Setup Wizard accesses speaker tunings from leading manufacturers.

In terms of connections, there are two female XLR line inputs plus a dedicated RTA mic input. All are electronically balanced and RF filtered for signal integrity.

• Line Inputs: 2 × female XLR, electronically balanced, RF filtered, >50 kΩ
• RTA Mic Input: 1 × female XLR with +15 VDC phantom power, EIN < -117 dB
• Conversion uses dbx Type IV A/D at 48 kHz for a 112 dB A-weighted dynamic range.

Outputs and Processing

Six male XLR outputs are provided for full-range, 2-way, or 3-way systems, with per-channel 8-band parametric EQ, a limiter, and alignment delay for precise control.

• Line Outputs: 6 × male XLR, electronically balanced, 120 Ω, +20 dBu max
