Lab Gruppen D SERIES LAKE D 10:4L 1000W Amplifier with 4 Flexible Output-Channels, Lake Digital Signal Processing and Digital Audio Networking for Installation Applications

Product Overview

The Lab Gruppen D 10:4L D Series Lake is a 1,000W 4-channel installation amplifier with onboard Lake DSP, Dante 8x8 dual-redundant audio networking, and IDEEA Class D direct drive Hi-Z output in a 1U rack-mount chassis. The D 10:4L delivers the full D Series Lake platform including Lake Controller configuration, four-level input redundancy, and native 70V/100V constant-voltage operation without external transformers. Specifying engineers, AV integrators, and IT/facilities managers planning Dante-networked distributed audio systems will find the D 10:4L D Series Lake a complete 4-channel DSP amplifier solution for conference rooms, multi-zone commercial audio, and permanent installed sound environments.

Product Description

The D 10:4L manages 1,000W total burst output across four channels via Lab Gruppen's RPM (Rational Power Management), which dynamically reallocates burst power from idle channels to those under load. With all four channels driven, each delivers 250W into 2, 4, 8, and 16 ohm Lo-Z loads and 250W at 25V/70V Hi-Z, with 175W at 100V Hi-Z. Single-channel maximum output reaches 1,000W at 2.67 ohm, 4 ohm, and 8 ohm loads, 1,000W at 70V, and 700W at 100V, demonstrating the available burst headroom RPM provides in real installations where not all channels are at full load simultaneously.

The IDEEA Class D output stage drives 70V and 100V constant-voltage speaker distribution natively without requiring external step-up transformers, reducing rack space and cabling complexity. Lake DSP is available for every channel, providing parametric EQ, linear-phase and FIR crossover filters, alignment delay, LimiterMax peak and RMS limiters, Raised Cosine MESA EQ, and full input/output routing configurable via Lake Controller software. Dante 8x8 dual-redundant networking with AES67 support operates at selectable latency from 0.25 to 5.0ms across daisy-chain and redundant topologies. Four AES3 digital inputs handle sample rates up to 192 kHz at 24-bit, and four balanced analog inputs with Iso-Float ground isolation support all common signal sources. Four-level input redundancy configured in Lake Controller provides automatic failover between Dante, AES3, and analog sources. The Breaker Emulation Limiter is fixed at 8A on this model. Dynamic range exceeds 112 dB with gain range of 22 to 44 dB.

Frequently Asked Questions

Q: Does the D 10:4L D Series Lake support 70V and 100V speaker systems without additional hardware?

A: Yes. The IDEEA Class D output stage provides native direct drive to 70V and 100V constant-voltage speaker lines. No external step-up transformers are required, simplifying wiring and reducing the total hardware needed for constant-voltage distributed audio installations.

Q: What is the total power of the D 10:4L and how does RPM affect multi-zone installations?

A: The D 10:4L provides 1,000W total burst power. RPM (Rational Power Management) allows burst power to be dynamically redistributed: if one or two zones are at low demand, their unused burst capacity is available to other channels needing more output. This makes the overall system more responsive to real-world program material compared to a fixed per-channel power architecture.

Q: How is the D 10:4L D Series Lake configured and monitored?

A: All DSP parameters, input routing, redundancy settings, and amplifier control are configured via Lake Controller software over the Dante network. The CAFE Equipment Specification Predictor (ESP) can be used during system design to predict amplifier and loudspeaker behavior before physical installation.

Q: What input formats does the D 10:4L support?

A: The D 10:4L accepts Dante (8x8, AES67), AES3 digital (four inputs, up to 192 kHz / 24-bit), and balanced analog via Iso-Float inputs (four channels). All three can be connected simultaneously, with four-level input redundancy in Lake Controller managing automatic failover between sources.

Q: What is the difference between the D 10:4L standalone listing and the D 10:4L D Series Lake listing?

A: Both listings represent the same Lab Gruppen D 10:4L amplifier (SKU: D104LUS) at the same specification. The D Series Lake listing is presented as part of the D Series Lake product grouping for customers browsing the full D Series range.

Q: What protection does the D 10:4L provide to connected loudspeakers and the mains circuit?

A: LimiterMax peak and RMS limiters in the Lake DSP protect connected loudspeakers from over-excursion and thermal damage. The fixed 8A Breaker Emulation Limiter (BEL) provides mains circuit protection by limiting current draw to prevent breaker trips during peak demand events.

Q: What warranty and support does Creation Networks offer for the D 10:4L D Series Lake?

A: The D 10:4L carries the Lab Gruppen manufacturer warranty. Creation Networks provides pre-sales system design support and can assist customers in locating authorized Lab Gruppen service centers for technical and warranty service.
