5. Introduction 5. Introduction 5.1. Welcome Thank you for choosing the Lab.gruppen D Series for your sound offered by this product. For fast installation and use of this product, your welcome package includes a printed copy of the D Series Quick Start Guide (QSG). 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.
5. Introduction 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 flexibility in allocating power output across each channel to match requirements, for more efficient use of amplifier inventory • Any channel is capable of being significantly scaled up to match power requirements.
6. Installation 5.3.3. Other Documentation This Operation Manual is intended to serve as a guide and reference to the operation and maintenance of the D Series Lake hardware platform. Comprehensive information is given regarding installation, connection and operation of the front panel interface. D Series Lake amplifiers are designed for configuration and operation using the Lake Controller and CAFÉ software programs.
6. Installation 6.2. Mounting D Series is made for mounting in 19 inch racks. Four screw holes are available for attachment of the amplifier to the racks front rack rail. This device has no top or bottom vents; therefore, units may be stacked directly on top of one another. Sufficient space should be available at the rear to accommodate connectors and cables. In addition, allowance must be made for cable or loom bends within a rack. 6.2.1.
6. Installation 6.2.2. Mounting front grille The front grille is shipped on top of the amplifier inside the box to protect it during shipping. The front grille adheres to the amplifier with magnets. Hold the front grille with your fingers in each of the side cutouts and slide it gently into place straight from the front. NOTE: Always ensure the dust filters behind the detachable front panel are clean to ensure maximum possible airflow.
6. Installation 6.4.1. Low voltage country considerations Although the D Series has a wide range of operating mains voltage, some considerations can be applicable for low voltage regions. D Series performs well throughout the specified nominal voltage range but has slightly better efficiency at higher voltages.

11. Operation and performance Secondary Connector – The secondary network connector can be used to create a Dante dual–network topology by connecting all secondary network connectors to a separate Ethernet switch, ensuring full redundancy in the event of a network component failure. Alternatively, the secondary network connector can be used to daisy–chain multiple Lake devices (LM, PLM, PLM+ or D Series), if Dual Redundancy is Disabled from the Lake Controller.

11. Operation and performance 2000 W SUB LOW MID HIGH D Series -11.2: Amp channels power adjusted to match the loudspeaker requirements Figure Amp channels power adjusted to match the loudspeaker requirements on a D 80:4 Auto RPM: The frame will automatically allocate power per output channel according to the ISVPL settings in the speaker preset (per module output) in Lake Controller. Auto RPM assumes a nominal impedance of the Load and applies an approximate power allocation.
11. Operation and performance 11.3.1. Inter–Sample Voltage Peak Limiter (ISVPL) The ISVPL is a high quality voltage limiter that can deliver seamless limitation to any desired level. It ensures that the voltage at the output terminals never exceeds the defined threshold. It operates on these principles: • The signal is delayed slightly to allow the ISVPL to look–ahead and reduce the gain before voltage in excess of the threshold can appear at the output.

Refer to Section 14.1 for more information on warnings and faults. 11.3.4. Breaker Emulation Limiter (BEL™) The BEL models the temperature in the external breaker and limits the mains current to prevent the breaker be selected for Frame Replace support). The desired nominal current value can be set from 1 to 32 Arms.
11. Operation and performance NOTE: For Slimeline models, to optimize the CAL’s behavior when playing into a low impedance load, manually set the desired ISVPL to reflect the real peak voltage output to allow for a higher average current. 11.3.7. Voltage Clip Limiter (VCL) If current draw from the unit’s power supply is too high, the PSU’s regulation capability may be exceeded and the internal voltage rails may drop and cause clipping.
11. Operation and performance channel Temperature Limiter (ATL) will engage at approximately 95% of the maximum allowable temperature. When ATL is engaged, it will try to reduce the power output to avoid that the amp channel goes into temp fault, i.e. muting. Limiting is removed when temperature falls below the ATL threshold. 11.3.8.2. Power Supply / DSP A power supply (PSU) or DSP temperature warning or fault is indicated by the Temp LED.

11. Operation and performance The presence of a short circuit (or low impedance) is re–tested every six seconds, and the output remains muted until the fault clears. 11.3.12. Power supply protection The power supply is very advanced and has several internal control and monitoring functions. Should any of these fail, the power supply will shut down to prevent damage or limit severity of the failure. If the power supply shuts down audio will be muted.
11. Operation and performance D Series features a universal power supply with power factor correction (PFC). The device can accept any mains voltage, from 65 V to 265 V, allowing it to function worldwide in many different configurations. The PFC reduces current peaks on the lines and reduces the requirements placed on the mains distribution system. D Series units offer an unparalleled power factor extremely close to one. 11.4.1.
11. Operation and performance 11.6. LoadPilot Load Monitoring 11.6.1. Introduction LoadPilot is a feature in D Series amplifiers that can continually monitor the integrity of loudspeakers and cables connected to the outputs to ensure that they are functioning properly and free from major anomalies or faults. By implementing LoadPilot, systems incorporating D Series amplifiers can be certified in compliance with voice evacuation standards such as EN54–16 and NFPA72.
11. Operation Operation and and performance performance 11. 11.6.3. Manual configuration 11.6.3.1. Functional description Manual configuration can be used in special cases where proper functioning requires setting of custom measurement frequencies, custom measurement levels, custom warning thresholds, or combinations of the three.
11. Operation and performance 12. Lake Processing and Lake Controller 11.6.4. Indication The LoadPilot feature constantly monitors the impedances at the two given pilot tone frequencies and compares to the measured thresholds. The following faults and warnings can be triggered. • Speaker shorted warning – Both tones below lower threshold. Corresponds to a distant short circuit that can either be in the cabling or in the speaker. • Speaker damaged warning – One of the tones is below or above thresholds.
12. Lake Processing and Lake Controller 12. Lake Processing and Lake Controller 11.7.2. AES67 When the device is in AES67 enable mode, the device is in 48 kHz only (also for Dante subscriptions/transmissions). The receiver latency for AES67 subscriptions is 2 ms. Transmission flows are Multicast only. AES67 subscriptions can only be configured in Dante Controller. The AES67 transmitter must support the SAP (Session Announcement Protocol).

13. System configuration tutorial 13. System configuration tutorial Using the System Presets function in the Lake Controller, entire system configurations can be stored and recalled across a network of Lake devices, including D Series Lake, LM, PLM and PLM+ Series devices. This enables fast retrieval and switching of entire system configurations as minimal data is being sent between the Controller and Processors. 13.

14. Appendix 14.3. Maintenance During normal operation a D Series device provides trouble–free service. If the front panel display requires cleaning, use a soft cloth only; do not use solvent cleaners. The dust filters on both sides of the front panel, behind the grilles, should occasionally be removed and cleaned to ensure maximum airflow through the device. Disconnect the unit from mains power prior to removing dust the filter, and ensure the dust filter is replaced prior to turning the unit back on.
