FAQ
How does the dbx 231s differ from the dbx 131s?
The 231s provides two channels of 31-band equalization in a single rack unit while the 131s provides only one channel. Both use 20mm sliders and the same Constant Q filter design, but the 231s is the better choice when two channels need independent equalization in the same rack space.
What is the dynamic range specification of the dbx 231s?
The dbx 231s achieves a dynamic range of greater than 112 dB, which is among the highest in its class and ensures the equalizer adds minimal noise or coloration to the signal path.
Is the dbx 231s compatible with professional balanced signal standards?
Yes, the 231s features both XLR and TRS balanced inputs and outputs, fully compatible with +4 dBu professional signal levels used in touring and installed sound equipment.

Frequently Asked Questions
What application requires a 31-band dual-channel graphic EQ with LED metering?
Professional sound reinforcement in concert halls, broadcast facilities, theaters, and installed PA systems where precise frequency control and real-time visual feedback of signal levels on each channel are critical.
How do 4-segment LED meters help during live sound operation?
LED meters provide instant visual confirmation of signal presence and levels on each channel without requiring external metering; they alert you to clipping or imbalance so you can adjust gains or fader settings in real time.
Why would a sound reinforcement system use both channels of the dbx 231s?
One channel might EQ the main PA outputs while the second controls monitor feeds, or both channels equalize left and right main speakers independently, giving the engineer complete tonal flexibility across the entire system.
How does 1/3-octave Constant Q resolution support professional sound reinforcement?
1/3-octave Constant Q EQ allows precise targeting of room acoustic problems, feedback frequencies, and tonal imbalances; the Constant Q design maintains consistent bandwidth across all frequency bands for predictable results.
How should I care for an LED metering display on this graphic EQ?
Avoid pointing bright lights directly at the LED display during operation; protect the unit from heat and humidity that could affect LED lifespan; check connections to ensure meters are receiving proper signal.
What distinguishes the dbx 231s from simpler dual-channel graphic EQs?
The dbx 231s combines 31-band 1/3-octave precision, built-in 4-segment LED metering, high dynamic range (>112 dB), and professional I/O in a single unit designed for mission-critical sound reinforcement where every detail matters.
What lead times apply to the dbx 231s for UAE and GCC delivery?
Delivery timing depends on your location and stock availability; contact the Procure.ae team to request a quote and confirm delivery timeframe for your order.
Can Procure.ae provide technical support for sound reinforcement system optimization?
Procure.ae can advise on best practices for system tuning and setup; reach out to discuss what technical guidance and support options are available for your installation.
What are the core technical specifications of the dbx 231s?
The dbx 231s is a dual-channel 31-band 1/3-octave Constant Q graphic EQ featuring greater than 112 dB dynamic range, switchable ±6 or ±12 dB boost/cut, 20mm nonconductive sliders, 4-segment LED metering, and XLR and TRS balanced I/O.
