Why Touring Engineers Prefer the PLM Series

In demanding live environments:

• weaker amplifiers begin compressing,
• bass becomes unstable,
• and system clarity starts collapsing.

The PLM20000Q is engineered specifically to prevent this.

Even during:

• heavy bass program material,
• long-duration festivals,
• or continuous high SPL operation,

the amplifier maintains:

• punch,
• clarity,
• and system control.

---

Integrated Lake DSP Processing

One of the most important features of the PLM20000Q is the integrated Lake DSP platform.

This transforms the amplifier into a complete loudspeaker management system.

---

Lake Processing Features

Integrated DSP Includes:

• FIR and IIR filtering
• Linear phase processing
• Advanced EQ control
• Crossover management
• Delay alignment
• Loudspeaker optimization

---

Why Lake DSP Matters

Lake processing is widely regarded as one of the most respected DSP platforms in professional touring audio because it provides:

• extremely precise system tuning,
• advanced loudspeaker control,
• and highly transparent processing.

---

Practical Benefit in Real Systems

For touring engineers, this means:

• faster system alignment,
• more consistent venue-to-venue performance,
• improved phase coherence,
• and better audience coverage consistency.

---

Dante Networking & Digital Audio Integration

The PLM20000Q is designed for modern networked audio environments.

---

Dante Integration

The amplifier includes:

• Dante digital audio networking
• Redundant network capability
• Low-latency audio transport

---

Practical Touring Advantage

This allows engineers to:

• reduce analog cabling,
• simplify signal distribution,
• and integrate directly into digital console ecosystems.

For large European touring productions, this significantly improves:

• deployment speed,
• troubleshooting,
• and overall rack organization.

---

Class TD® Amplifier Technology

The PLM20000Q uses Lab Gruppen’s proprietary Class TD amplifier topology.

This combines:

• the sonic quality of Class AB,
• with the efficiency advantages of Class D.

---

Real-World Acoustic Advantage

Compared to conventional amplifiers:

• heat generation is reduced,
• efficiency is improved,
• and transient response remains exceptionally fast.

This gives the PLM20000Q its:

• tight bass response,
• strong punch,
• and highly dynamic sound character.

---

Rational Power Management (RPM™)

One of the PLM Series’ most advanced features is Rational Power Management.

---

What RPM Does

RPM allows amplifier power to be dynamically distributed between channels depending on loudspeaker demand.

---

Practical Benefit

This improves:

• system flexibility,
• amplifier efficiency,
• and loudspeaker optimization.

For example:

• subwoofer channels can receive more available power,
• while HF channels use less.

This makes the amplifier highly adaptable across different touring systems.
