D&B Audiotechnik Q7 System – Complete Point Source Sound System (Q-Series)

The D&B Audiotechnik Q7 system is a high-output, point source PA system designed for professional sound reinforcement where direct projection, clarity, and flexible deployment are required. Built around the Q7 loudspeaker and Q-SUB subwoofers, this system delivers powerful full-range sound with minimal setup complexity, making it widely used across Europe for touring, corporate events, and medium to large-scale productions.

Unlike line array systems, the Q7 system is focused on direct sound delivery, providing immediate impact and strong midrange presence, particularly effective in open spaces, clubs, and live performance environments.

Key Features & Configuration

Dual 10″ Dipole LF Design:
The LF drivers are arranged in a dipolar configuration, providing controlled vertical dispersion and reduced unwanted rear energy, improving clarity in both indoor and outdoor environments.

---

Rotatable Constant Directivity Horn:
Allows flexible orientation for horizontal or vertical deployment, making the Q7 suitable for:

• Front-of-house systems
• Delay and fill positions
• Integration with Q1 arrays

---

Point Source Projection:
The Q7 system delivers:

• Strong forward sound projection
• High perceived loudness
• Immediate impact across the audience

---

System Configuration & Deployment

Typical System Setup

• 2 × Q7 per side (small system)
• 4–6 × Q7 per side (medium system)
• Q-SUB subwoofers (2–6 units depending on scale)
• D&B amplifiers for system control

---

Deployment Options

Ground-Stacked System:
Ideal for outdoor events and temporary setups.

Pole-Mounted System:
Used for smaller events and corporate applications.

Flown System:
Integrated into truss setups or combined with Q1 arrays.

---

Hybrid Configurations

The Q7 is often used as:

• Downfill for Q1 line arrays
• Outfill or delay speakers
• Standalone FOH system

---

Low-Frequency Integration (Q-SUB)

The system is typically paired with Q-SUB subwoofers:

• 18″ bass-reflex design
• Deep low-frequency extension
• Compatible with flown or ground-stacked setups

---

Practical Advantage

• Full-range system performance
• Tight and controlled bass response
• Scalable low-frequency output

---

Amplification & DSP Control

The Q7 system relies on d&b amplifiers:

• D12 (classic touring setup)
• D20 / D80 (modern DSP control)

---

DSP Features

• Loudspeaker presets
• Crossover and EQ
• Delay alignment
• System protection

---

Result

• Consistent system tuning
• Reduced setup time
• Reliable performance across venues

---
