Powered speakers are a beautiful thing. Everything you need bundled into one simple, tidy, portable package. Just grab ‘em and go, right? Well, you may think your powered speaker system is complete, but you’re missing half the picture. DriveRack PX is the other half. In another dbx industry first, we’ve created a processor specifically tailored for powered speakers. Utilizing our highly-acclaimed DriveRack technology, the PX picks up where your powered speakers leave off.

The DriveRack PX Powered Speaker Optimizer has everything you need to get the most out of your stereo powered speaker system. It even includes stereo or mono subwoofer support. With the included dbx M2 measurement mic, Auto-EQ corrects for audible deficiencies in the room environment. Our patented Advanced Feedback Suppression (AFS™) kills nasty feedback, allowing problem-free operation at higher sound levels, while our patented Subharmonic Synthesizer™ extends bass response for enhanced bottom end. With all that, you also get classic dbx compression and the protection offered by our graceful PeakPlus™ limiting. Your ears, your audience, and your powered speakers will forever thank you.

In spite of all that sophistication, rest assured we won’t overcomplicate the simplicity of your rig. Our exclusive Setup, Auto-EQ, and AFS Wizards, and out-of-the-box support for a host of JBL and other popular powered speakers, make setup a snap. Louder, cleaner, better sound than you thought possible from your powered speakers.

DBX DriveRack® 4820 Loudspeaker Management System

 

DriveRack® 4820

Loudspeaker Management System

Designed to provide incredible flexibility, sonic excellence and intuitive control for performance applications, the DriveRack 4820 is the next member of the hugely successful of the hugely successful DriveRack family. From the powerful 96 kHz DSP engine and standard analog and digital I/O, to the tamper-proof front panel, the 4820 provides all the processing, flexibility and control necessary for permanent installations.

The DriveRack 4820 is the next generation of the famous DriveRack family, and like its predecessor it is engineered to provide “Everything you need between the mixer and the power amps”. In keeping with this philosophy the 4820 includes four inputs and eight outputs with both analog and digital connectivity. The 96 kHz processing engine is capable of offering insert processing functions to customize the processing path for your application, in addition to the standard system processing functions all with extremely low latency and extended frequency response. From Signal Routing, EQ, and Bandpass Filters, to classic dbx® Dynamics and Feedback Suppression all the processing is available and with the sonic excellence that you would expect from the world’s leading system processing manufacturer. With all this processing power available, control is of paramount importance. The DriveRack 4820 provides a tamper-proof front panel, and is controlled by an easy-to-use GUI with optional wall panel controllers; so whether you application is Front of House system processing or Distributed system control, the DriveRack 4820 has what it takes.

• 48 and 96 kHz operation
• 4 analog and AES/EBU inputs
• 8 analog and AES/EBU outputs

DBX 1231 Dual Chanel 31-Band Equalizer

1231

Dual Chanel 31-Band Equalizer

The dbx® 12 Series were designed to meet the needs of the most demanding sound reinforcement environments, while offering the simplicity of straightforward controls. The 1231 provides standard features like dual-channels, 31 1/3 octave bands, ISO frequency centers, +/- 12 dB input gain range, and switchable 40Hz/18 dB per octave low-cut filters, but also includes other insightful features. These include 45 mm faders; selectable +/-6dB or +/-15dB boost/cut range for precise gain adjustments; XLR, barrier strip, and 1/4” TRS connectors for installation ease; balanced inputs and outputs for quiet operation; and chassis/signal ground lift capabilities for quick hum isolation. The visionary design of the dbx 12 Series makes your job easier.

The dbx 12 Series Equalizers were precision engineered to provide years of maintenance-free operation in any application. The magnetically isolated transformer, electronically balanced/unbalanced inputs and servo balanced/unbalanced outputs, RF-filtered inputs and outputs, and power-off hard-wire relay bypass with 2 second power up delay were steps our engineers took to ensure compatibility for all installations. Only the best components were utilized, yielding a 10Hz to 50kHz frequency response, greater than 90dB SNR (ref +4dBu), less than 0.005% THD +Noise (1kHz at +4dBu), and interchannel crosstalk of less than -80dB from 20Hz to 20kHz. All this attention to detail is contained in a 3U steel/aluminum chassis.

• Switchable boost/cut ranges of ±6 or ±15 dB
• Electronically balanced/unbalanced inputs
• Servo balanced/unbalanced outputs
• RF filtered inputs and outputs
• XLR, Barrier Strip, and 1/4″ TRS connectors
• -12dB/+12dB input gain range
• 18dB/octave 40Hz Bessel low-cut filter
• Chassis/signal ground lift capability
• Internal power supply transformer
• Power-off hardwire relay bypass with 2-second power-up delay
