Lab Gruppen D SERIES LAKE D 200:4L 20,000W Amplifier with 4 Flexible Output-Channels, Lake Digital Signal Processing and Digital Audio Networking for Installation Applications

Product Overview

The Lab Gruppen D 200:4L is the flagship 4-channel installation amplifier in the D Series Lake lineup, delivering 20,000 watts of total burst power for the most demanding large-scale commercial AV installations. Designed for integrators specifying audio systems in stadiums, arenas, theme parks, and performing arts centers, this rack-mount amplifier combines the D Series Lake DSP platform with Dante digital audio networking in a 2U chassis. The Lab Gruppen D 200:4L 4-channel DSP amplifier with Dante is the reference choice for commercial sound system designers who require maximum power density, comprehensive loudspeaker management, and network-integrated control in a single installation amplifier.

Product Description

The D 200:4L is built on the same Class-TD output stage technology proven in Lab Gruppen's PLM touring amplifier series, reengineered for permanent installation applications with features that directly address the needs of commercial AV system designers. At the center of its platform is Rational Power Management (RPM), a proprietary architecture that allows the 20,000W total burst power to be allocated freely across all four output channels. Rather than fixing each channel at a fixed wattage, RPM lets the integrator direct more power to the channels that need it — eliminating the over-specification waste common with conventional installation amplifiers.

Four full-featured Lake processing modules handle loudspeaker management on each channel, providing Classic, linear-phase, and FIR crossover options, fully parametric EQ, delay, and LimiterMax peak and RMS limiters for precise loudspeaker protection. Input signals are selectable from four analog inputs with Iso-Float ground isolation, four AES/EBU (AES3) digital inputs supporting sample rates up to 192 kHz, and eight channels of dual-redundant Dante networked audio with AES67 support — all routable on a per-channel basis with programmable failover to analog. Control and monitoring is handled via Lake Controller software over dual RJ45 Ethernet ports, with third-party integration available for Q-Sys, MediaMatrix, and other matrix platforms over UDP. The CAFE (Configuring Amplifiers For the Environment) software suite supports full system design, load modeling, and commissioning. Under-Voltage Limiting (UVL) keeps the amplifier operational during mains voltage drops, and a Breaker Emulation Limiter (BEL) prevents circuit breaker trips by profiling current draw behavior. The 2U rack-mount chassis includes front-to-rear airflow with an Intercooler cooling system, front-panel per-channel mute buttons with LED status indication, and rear terminal block connectors rated at 1000V/76A to handle up to 16mm² cable.

Key Features

• 20,000W Total Burst Power with RPM — Rational Power Management allows flexible reallocation of the full 20,000W across all four output channels to match actual load requirements.
• Onboard Lake DSP — Four full Lake processing modules per unit with Classic/linear-phase/FIR crossover, parametric EQ, delay, and LimiterMax peak and RMS limiters.
• Dante Digital Audio Networking — Integrated 8x8 dual-redundant Dante with AES67 support; supports daisy-chain and redundant network topologies with latencies from 0.25ms.
• Quad Input Flexibility — Selectable per-channel from 4 analog (Iso-Float), 4 AES3 digital, or 8 Dante inputs, with programmable analog failover.
• Class-TD Output Stage — Delivers Class-A/B sonic quality at Class-D efficiency with proprietary Intercooler high-efficiency cooling.
• Under-Voltage Limiting (UVL) — Maintains amplifier operation during severe mains supply voltage drops, critical for mission-critical PA and voice alarm systems.
• Breaker Emulation Limiter (BEL) — Configurable current threshold and breaker profile prevents nuisance trips on shared mains circuits.
• Third-Party Control Integration — Native integration with Q-Sys, MediaMatrix, and other control systems via UDP Ethernet protocol.
• 2U Rack-Mount Chassis — 483 x 88 x 424mm (W x H x D) with rear support brackets, removable dust filter, and touch-button front panel controls.
• Power Factor Correction — Greater than 0.98 PFC reduces current draw and simplifies UPS and mains infrastructure sizing.

Frequently Asked Questions

Q: What is the per-channel power output of the D 200:4L?

A: The D 200:4L delivers 20,000W of total burst power shared across four channels via Rational Power Management (RPM). RPM allows any channel to be allocated significantly more power than a fixed-channel amplifier would permit, so the per-channel output depends on your RPM configuration and load conditions.

Q: Does the D 200:4L support 70V and 100V constant-voltage distribution?

A: Yes. The D Series Lake platform supports Hi-Z constant-voltage operation at both 70V and 100V alongside standard Lo-Z loads from 2 to 16 ohms, making it suitable for distributed commercial sound systems.

Q: Can the D 200:4L be integrated with Q-Sys or other third-party control systems?

A: Yes. The D Series Lake platform supports third-party control integration with Q-Sys, MediaMatrix, and other matrix systems via a dedicated UDP Ethernet protocol. Dante Controller and Lake Controller software are used for audio routing and DSP configuration.

Q: What happens if the Dante network fails?

A: The D 200:4L supports programmable input failover to analog on a per-channel basis. In redundant Dante network configurations, the unit automatically switches to the backup network path, ensuring continuity in mission-critical PA and voice alarm systems.

Q: Is the D 200:4L suitable for voice alarm (VA) and mass notification systems?

A: Yes. The amplifier includes dedicated on-board surveillance and load monitoring, redundant audio inputs, and on-board system surveillance functions that support voice alarm system compliance requirements.

Q: What software is used to configure and commission the D 200:4L?

A: Lake Controller software is used for DSP programming, loudspeaker preset management, and system monitoring. CAFE (Configuring Amplifiers For the Environment) provides system design tools including the Equipment Specification Predictor for load planning, heat modeling, and UPS sizing. Dante Controller handles Dante audio network routing.

Q: What warranty and support does this product carry?

A: Lab Gruppen products are backed by the manufacturer's standard warranty. Creation Networks provides pre-sales specification support and can connect you with authorized Lab Gruppen service centers for technical and warranty service.

Q: What mains power configuration is required for the D 200:4L?

A: The amplifier operates on 100–240V AC, 50–60 Hz with a nominal operating range of 70–265V AC. It uses an industry-standard twist-lock power connector rated at 250V/32A. Wall plug configurations are selectable at time of order for regional requirements.
