It's Easier than Ever to Take Control of Your PA System!

The dbx DriveRack PA+ loudspeaker management system takes an already great product and adds a ton of new features to make it even better! After managing to pack a complete speaker management system into an affordable 1U rackmountable box, dbx added great new features to the DriveRack PA+, such as a USB connection, updated settings for the newest speaker lines and amp products, front-panel mute buttons for easier troubleshooting, a faster and easier to use Auto EQ Wizard, and full-time RTA that allows you to easily tune your system on your own. Of course, dbx kept all the functionality and features of the first DriveRack alive in the amazing DriveRack+.

dbx DriveRack PA+ PA Loudspeaker Management System at a Glance:

• A great unit — made even better
  
• A complete PA-system speaker managment system &mdash an FOH engineer in a box
  
• Linkable 28-Band graphic equalizer, real time analyzer, and auto EQ
  
• Automatic feedback eliminator and EQ for immediate sound improvement
  
• 120A Subharmonic synthesizer, crossovers, parametric EQs, and Peak Plus limiters and alignment delay
  
• Industry-standard dbx stereo compressor

A great unit — made even better
The DriveRack PA+ is the next generation of an already outstanding loudspeaker management system. The original DriveRack PA, known for setting the standard for complete speaker management, has given thousands of users an easier way to make their systems sound better than they ever imagined. The new PA+ builds on this strong reputation by staying true to its predecessor while providing more great features and improved functionality. The DriveRack PA+ gives you updated speaker and amplifier settings to include all current JBL portable speaker lines, latest Crown amplifiers, and many other amp and speaker manufacturers. It also features a faster and more friendly Auto EQ Wizard, an Auto Level Wizard to fine-tune each speaker's level, Full-time RTA to allow users to tune systems on their own, and power on/off mute circuitry for softer and safer power cycling. The new unit features front-panel mute buttons for faster and easier system troubleshooting, plus a new look — a titanium silver color scheme with a bright LCD screen.

FOH engineer in a box
DriveRack PA+ can be not only your first upgrade to a simple PA, but also a unit that can grow with your system as you expand it. Any band or performer who wrangles a portable sound system around without help from an engineer will appreciate both the audible improvements brought by the dbx DriveRack PA+. The Auto EQ and AFS functions can immediately benefit performers with modest PA systems who can't employ an engineer or spend a few years becoming one. The unit's setup wizards greatly simplify the process of getting up and running. When you're ready to delve into the deepest functions of the DriveRack PA+ in order to get the most out of its no-compromise design, you'll find that having such a rich feature set means that as your system grows, the DriveRack PA+ can grow with it.

RTA, Auto EQ and feedback elimination
The Auto EQ function is one of the key features that the DriveRack PA+ offers for customizing a PA system to match the acoustic response of a specific venue. It has a pink-noise generator and Real Time Analyzer to adjust system response using the 28-band graphic EQ. A flat-response omnidirectional mic acts as the RTAs "ear." Dbx makes an inexpensive condenser mic, the RTA-M to use with the DriveRack PA+.

The Auto EQ works impressively. The RTA requires a minimum sound-pressure level (SPL) at the mic to do its thing. It prompts you to raise it to "performance level," which means that it helps to have a rough idea of how loud a performance will be. There are three levels of precision. Even at the lower settings, the Auto EQ is very effective. For instance, we patched two DriveRack PA+ units into a theater installation, where the left and right clusters were Cerwin-Vega and the center cluster was JBL. The Auto EQ matched the sound of the two systems better than anyone had previously managed by ear, and the speakers also sounded quite good. Indeed, we needed to make no other adjustments to the system EQ during that show.

The Advanced Feedback Suppressor is as good as any that we've tried. If you set the DriveRack PA+ AFS at soundcheck it can be quite useful, particularly if your band has no soundperson to keep an ear on things. The combination of Auto EQ and AFS can tune your system very effectively.

Audio flexibility
Then, when you decide to expand your system — let's say you add subwoofers — the crossovers, delays, and parametric EQ in the DriveRack PA+ are ready to help you easily integrate your new additions. In fact, the unit's software includes setup Wizards to take the trauma out of tuning biamped or triamped speaker systems. For the more technically inclined, there's also compression and a subharmonic synthesizer on board to allow further audio flexibility.

The crossover has several filter configurations and accommodates biamped and triamped speaker systems, including mono or stereo subwoofers. Properly tweaking the crossover and each output's parametric EQ should bring a biamped or triamped speaker system very nearly flat, leaving the graphic EQ free to handle environmental and creative EQ concerns. Each output can be delayed up to 10 milliseconds to align the drivers in time.

Industry-standard dbx stereo compressor
The compressor, which goes across your entire mix, features both hard-knee compression and ten levels of Over Easy compression. (With the latter, compression starts below the threshold, and the ratio increases as the threshold is approached.) The compression sounds very good when properly applied. Dialing in a 2:1 compression ratio and about 5dB of gain reduction will add a musical fatness your sound. There are also individual peak-limiter modules for speaker protection before each of the six outputs on the DriveRack+.
