5. Introduction

5.1. Welcome

Thank you for choosing the Lab.gruppen D Series for your sound reinforcement needs. We are conﬁ dent that you

will be pleased with the performance, unique features, conﬁ guration ﬂ exibility, reliability, and long-term durability

offered by this product.

For fast installation and use of this product, your welcome package includes this printed copy of the D Series

Quick Start Guide. It provides a brief introduction to the features and functionality of the D Series, and it also

contains the information required to safely install the product and place it in service. Please read through thoroughly

to become acquainted with the basic conﬁ guration and control options available. It is recommended that you also

review all other product documentation to ensure familiarity with the various conﬁ guration and control options.

Thank you again for placing your conﬁ dence in Lab.gruppen products.

5.2. D Series: Two versions available

D Series is an advanced, high-power installation ampliﬁ er platform designed for demanding applications, primarily

in performance venues. For the utmost ﬂ exibility in processing and networking, the D Series is available in two

versions: the Lake version, with a full slate of Lake processing algorithms and Dante networking; and the Tesira by

Biamp option for full integration in a Tesira system and with Ethernet AVB audio transport. D Series Tesira versions

are available in three output power levels, whereas the D Series lake versions are available in six output models.

The six Lake power output models come in two form factors. Three high power models in a standard form factor

and three lower powered models in a slimline, single rack unit, form factor.

This Quick Start Guide is for use with Lake processing versions only, and applies to models at all six output power

levels. More detailed information is available in the full Operation Manual, available at Lab.gruppen.com.

6. Feature summary

• Four channels with six levels of total available frame power output: 20000 W, 12000 W, 8000 W,

4000 W, 2000 W and 1000 W

• Rational Power Management (RPM)

• True ﬂ exibility in allocating power output across each channel to match requirements, allowing more

efﬁ cient use of ampliﬁ er inventory

• Any channel is capable of being signiﬁ cantly scaled up to match power requirements

• Dedicated on-board surveillance and load monitoring for voice alarm applications

• Advanced universal power supply

• Regulated Switch-Mode Power Supply (R.SMPS™) maintains stability through ﬂ uctuations in mains voltage

• Best-in-class Power Factor Correction (PFC)

• Current Draw Modeling (CDM™) reduces peak mains draw

• Breaker Emulation Limiter (BEL™) responds to available mains distribution

• Under-Voltage Limiting (UVL™) allows continued operation through mains voltage drop

• CAFÉ (Conﬁ guring Ampliﬁ ers For the Environment) software incorporates ESP™ (Equipment Speciﬁ cation

Predictor) to assist in design, equipment speciﬁ cation and commissioning

• Features controlled by on-board DSP

• Ampliﬁ er gain is set in the digital domain and controlled via the Lake Controller software

• ISVPL™ - The Inter-Sample Voltage Peak Limiter (ISVPL) tailors each channel’s power output to the

characteristics of the connected load

• Load Veriﬁ cation & Performance Monitoring - A comprehensive set of proprietary DSP-based tools

enables load veriﬁ cation and real-time performance monitoring

NOTE: The D 200, D 120 and D 80 models have the possibility to bridge two power outputs to further

increase scalability. This feature is not available on the D 40, D 20 and D 10 models.
