Speaker Management, EQ, and System Control for Pro Audio Rigs

The difference between a system that sounds decent and one that sounds dialed usually comes down to what's happening between the mixer and the amps. Square Cable stocks signal processing gear for installs, rental fleets, and production rigs, from a single dbx DriveRack protecting a bar PA to full DSP matrix processors from Ashly, Symetrix, and Allen & Heath running multi-zone venues. We carry the brands integrators spec: dbx, Ashly, Symetrix, ART, Furman, and more.

Speaker Management Systems: One Box Between Console and Amps

A dedicated speaker management system is still one of the smartest line items on any install quote or rental package. Whether it's a dbx DriveRack on a portable rig or a networked DSP in a rack closet, a good audio processor handles the jobs that protect your gear and your reputation:

  • Crossover audio routing to send the right frequencies to subs, tops, and fills
  • Speaker protection with limiting and driver alignment, so a volunteer or bartender can't cook the system
  • Feedback suppressor engines that catch ringing before the client hears it
  • Room EQ and auto-tuning to get repeatable results across different venues
  • Delay settings for fills and distributed speakers in larger rooms

For rental companies, that means rigs that come back working. For installers, it means fewer callbacks.

Wholesale Signal Processing for Integrators, Production, and Rental Accounts

Square Cable works directly with integrators, installers, production companies, and rental houses on volume pricing and availability. Signal processing is where projects often stall on lead times, so if a specific audio processor is backordered, we'll tell you straight and point you to a comparable unit from another brand we've tested. Bars, restaurants, schools, and houses of worship outfitting through a contractor can also lean on us for system-level recommendations, not just boxes.

EQ, Dynamics, and System Tuning Tools

Beyond loudspeaker management, this collection covers the processing that shapes and cleans up signal through the whole chain. Depending on the application, that might include:

  • Graphic equalizer units for monitor rings and quick room correction on analog rigs
  • DSP matrix processors for zoned audio in restaurants, schools, and multi-room facilities
  • Compressors and channel strips for broadcast, recording, and front of house racks
  • Power conditioning from Furman to keep racks clean and protected
  • DI boxes, splitters, and wireless signal tools for stage distribution

If you're standardizing racks across a fleet or spec'ing processing for a chain of locations, we can help you pick one platform and stick with it.

Can a dbx DriveRack replace my rack of separate EQ, crossover, and limiter units?

Yes, that's the whole point. A DriveRack combines crossover, EQ, limiting, and feedback suppression in one rack space, which is why it's a staple in portable rigs and small venue installs.

Do I still need a feedback suppressor if the venue has a digital console?

Usually not as a separate box. Most modern processors and digital mixers have feedback elimination built in, but a dedicated unit still makes sense for speech-heavy rooms with untrained operators.

Is a graphic equalizer outdated for installs?

Not outdated, just situational. DSP handles most correction now, but a graphic EQ is still handy on analog rigs and monitor sends where you want hands-on control without menus.

Can you help spec DSP for a multi-zone install?

Absolutely. Send us the zone count, sources, and control needs, and we'll recommend matrix processors and accessories at dealer pricing.
