D SERIES Lake Operation Manual rev 3.0.1

5.3. Feature summary

5.3.1. Features common to both D Series variants

• 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 exibility in allocating power output across each channel to match requirements, for more efcient

use of amplier inventory

• Any channel is capable of being signi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 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 (Conguring Ampliers For the Environment) software incorporates ESP™ (Equipment Specication

Predictor) to assist in design, equipment specication and commissioning

• Features controlled by on–board DSP

• Ampli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 Verication & Performance Monitoring – A comprehensive set of proprietary DSP–based tools

enables load verication and real–time performance monitoring

NOTE: The D200, D120 and D80 models have the possibility to bridge two power outputs to further

increase scalability. This feature is not available on the D40, D20 and D10 models.

5.3.2. Features unique to Lake variant

• Lake’s exclusive classic/linear–phase/FIR speaker processing platform with four throughputs

• Group control with Raised Cosine™ MESA EQ™ asymmetric lters

• LimiterMax™ peak and RMS limiters

• Extensive loudspeaker preset database (Lake LoadLibrary™)

• Comprehensive clocking management system with low latency sample rate conversion

• Full support for Dante Controller

• Multiple and redundant inputs with programmable failover

• Four “Lake Class” analog inputs with Iso–Float™ ground isolation

• Two AES3 digital inputs (4 audio channels)

• Eight dual–redundant Dante network audio inputs

• Comprehensive 3rd party protocol for integration potential with third party matrix systems via purpose–

developed middleware
