What Is the d&b Audiotechnik J Series?

Introduced by d&b Audiotechnik in the early 2000s, the J Series was a monumental leap in large-scale PA systems.

Key Components of the J System Package

A full used d&b Audiotechnik J System Package typically includes:

• J8: 80° horizontal dispersion

• J12: 120° horizontal dispersion

• J-SUB: cardioid subwoofer with three drivers

Why Choose a Used d&b Audiotechnik J System Package?

In today’s budget-conscious touring industry, cost-effectiveness matters. A used J System can cost 40–60% less than a new SL-Series rig, while still outperforming many newer mid-tier systems. Plus, d&b’s reputation for longevity ensures that even used gear remains rock-solid and rider-friendly.

Audio Excellence: Sound Quality and Performance

Let’s talk numbers:

• Max SPL: Up to 145 dB

• Frequency Range: 32 Hz – 20 kHz

• Coverage: Exceptionally smooth, thanks to arrayable design

Engineers praise its natural voicing, tight low end, and silky high-frequency response, especially when tuned with ArrayCalc and R1 software.

Road-Tested Reliability

J Systems were built with the road in mind—reinforced enclosures, weather-resistant grills, and touring racks ensure they survive the toughest conditions. Thousands of shows later, they still deliver every night.

Deep Dive: The J8 and J12 Line Array Modules

• J8: 2 x 12″ LF + 10″ MF + 1.4″ HF

• J12: Similar build with a wider dispersion for front fill or wider venues

These boxes are horn-loaded, maximizing efficiency and throw. Use J8s for long throws, and J12s for downfill or nearfield.

---

Subwoofers: J-SUB vs. J-INFRA

• J-SUB: A 3 x 18″ cardioid beast

• J-INFRA: 3 x 21″, designed to push sub-30 Hz frequencies with ease

Together, they offer flexible low-end coverage, from punchy kicks to earth-shaking EDM lows.

---

Amplification and Control: D80 Amplifiers

The D80 is the backbone of the system. With DSP presets, R1 remote control, and 4-channel 4000W output, it’s not only powerful but smart. You can store venue-specific settings, recall configurations, and optimize performance wirelessly.

---

Rigging and Deployment

Quick, safe rigging is essential for big productions. The J Series features:

• Integrated rigging with snap-in pins
