dbx DriveRack PA2
US
£489.70 20Hz - 20kHz, +/- 0.5dB 10ms per channel (60ms total) AutoEQ; AFS (Advanced Feedback Suppression); dbx Type IV Conversion

The dbx DriveRack PA2 is a 1U loudspeaker management system with configurable 1/2/3-way crossovers, AutoEQ, advanced feedback suppression, limiter and parametric/graphic EQs, plus mobile/Ethernet control. It suits live PA and speaker-management use where quick setup and automated room tuning are needed. It includes driver alignment delays and a 48kHz sample rate for reliable digital processing.

★ Ideal for

Good for beginners using studio monitors because its AutoEQ and setup wizards simplify room tuning and its 20Hz-20kHz response plus alignment delay controls (10ms/channel) let users achieve correct crossover and time alignment without deep DSP knowledge.

DSPeaker Anti-Mode 8033S
US
£373.81 5-250 Hz 0/180 deg. 24-band Infinite Impulse Response filter (IIR)

Automatic, one-button subwoofer room-correction unit that measures and corrects 16-250 Hz using precise digital filters and minimum-phase filtering to reduce room resonances and improve bass clarity. Includes a measurement microphone, selectable EQ profiles, and low latency for fast transient response, suited for home theater and stereo subwoofer setups.

★ Ideal for

Good for beginners because its fully automatic calibration, IIR 24-band correction across 16-250 Hz, and plug-and-play RCA connections remove the need for manual DSP tuning.
