the mains power is on.
3.4.3. Radio interference
A sample of this product has been tested and complies with
the limits for the European Electro Magnetic Compatibility
(EMC) directive. This equipment has also been tested and
found to comply with the limits for a Class A digital device,
pursuant to Part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful
interference from electrical equipment. This product uses
radio frequency energy and if not used or installed in
accordance with these operating instructions, may cause
interference to other equipment, such as radio receivers.
This Class A digital apparatus complies with Canadian ICES-003.
Cet appareil numérique de la classe A est conforme à la norme NMB-003
du Canada.
However, there is no guarantee that interference will not
occur in a particular installation. If this equipment does cause
harmful interference to radio or television reception, which
can be determined by turning the equipment on and off, the
user is encouraged to try to correct the interference by one or
more of the following measures:
• Reorient or relocate the antenna.
• Increase the separation between the equipment and
re cei ver.
• Connect the equipment to an outlet on a circuit different
from that to which the receiver is connected.
• Check if the affected unit complies with the EMC limits for
immunity, (CE-labeled). If not, address the problem with
the manufacturer or supplier. All electrical products sold
in the EC must be approved for immunity against
electromagnetic elds, high voltage ashes, and radio
interference.
• Consult the dealer or an experienced radio/TV technician
for help.
3.4.4. Speaker damage
Amplier apparatus is very powerful and can be potentially
dangerous to both loudspeakers and humans alike. Many
loudspeakers can be easily damaged or destroyed by
overpowering them. Always check the speaker’s continuous
and peak power capabilities. Although the ampliers
attenuators can be used to reduce the overall gain, an
increase of the input signal can result in full output power,
which may cause damage to connected speakers.
3.4.5. Maintenance
For safe and reliable operation, the dust lters on both sides
of the front panel, behind the grilles, should be removed and
cleaned regularly to ensure maximum airow through the
device.
If the dust lters are not maintained there will be safety
risks; for example, high internal temperatures could ignite
the dust and start a re. There is also a risk that the unit will
malfunction since it is dependent on constant airow from
front to rear. If the dust lters are not clean and the unit
malfunctions, any resulting problems will not be covered by
the warranty.

• D Series Lake Quick Start Guide (this document)
• AC mains lead (power cable) with Neutrik® powerCON® connector and AC socket plug according to
ordering selection
• Rear brackets for additional rack support (pair) along with associated mounting hardware
• Connector kit including all needed connectors
• Front grille and dust lter assembly
NOTE: Depending on the model, the connector kit might include more connectors than applicable for the product
you have. Select those connectors required for your unit and application.
Please keep the original carton and associated packaging to facilitate shipping of the device should the need arise.
7.2. Mounting
D Series is made for mounting in 19 inch racks. Four screw holes are available for attachment of the amplier 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. Sufcient 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.
7.2.1. Rear Mounting
Two rear support brackets, along with associated mounting hardware, are included with the D Series device. It is
strongly recommended that these are used wherever possible. Fit the brackets to the vertical rails at the rear of the
rack. The following diagrams show the tting options for xed and removable installation. The support brackets are
reversible and may be tted to point either to the front or rear of the rack; the proper orientation depends on the
rack depth and position of the rear rack rails.

7.2.2. Mounting front grille
The front grille is shipped on top of the amplier inside the box to protect it during shipping. The front grille adheres
to the amplier with magnets. Hold the front grille with your ngers in each of the side cutouts and slide it gently into
place straight from the front.
NOTE: Always ensure the dust lters behind the detachable front panel are clean to ensure maximum possible
airow. The exterior front panel is held in place by powerful magnets but is easy to detach by using your ngers in the
openings at the each side. To clean the foam lter, detach it from the exterior front and gently use a vacuum cleaner
or gently shake it. Remount with the opposite procedure. Never operate the amplier without the dust lter installed.

8. Cooling and fan operation
8. Cooling and fan operation
D Series devices use a forced-air cooling system with airow from front to rear, allowing high continuous power
levels without thermal problems. To facilitate maximum air ow, ensure that no objects such as rack doors or
lids are placed at the front or rear of the rack. Never attempt to reverse the airow. Make sure an adequate air
supply is provided in front of the D Series device, and that the rear of the device has sufcient space to allow
air to escape. It is recommended to keep the ambient temperature around the device as cool as possible. An
increased temperature can have a signicant negative impact on the expected lifetime on the components
inside the D Series device.
NOTE: Fit solid blanks (not ventilation blanks) to unused rack spaces to ensure effective air circulation. Leaving
gaps in between items of equipment degrades the effectiveness of forced-air cooling.
If installing one or more D Series devices in a rack with other fan-cooled equipment, conrm that all other
equipment also uses front-to-rear airow for cooling. If this precaution is not observed, there is a risk of
overheating, as units with the reverse airow will be drawing in air which has already been heated by the
D Series devices.
The D Series device is equipped with a sophisticated temperature sensing system which protects it from any
overheating which may occur as a result of inadequate ventilation.
9. Operating voltage
D Series has a universal power supply and its mains nominal and operating voltages are specied in the Technical
Specications (pages 26-27). D Series can be ordered with a variety of mains plugs. If the mains plug (AC plug)
tted to the mains cable (AC cord) is not appropriate for your country it can be removed and a locally-sourced one
tted instead. If you are not 100% condent of your competence to replace the mains plug (AC plug), the task
should be carried out by qualied personnel.
NOTE: In-rush current is controlled and limited during the soft-start sequence. This enables multiple D Series
Devices on the same AC mains circuit to be turned on simultaneously.
9.1. 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 specied nominal voltage range but has slightly better
efciency at higher voltages. For regions with nominal voltage below 140 V, one could consider connecting the
amplier in a three-phase delta or two phase split-phase conguration.
NOTE: Following connections applicable only for resulting voltage inside the ampliers nominal voltage range.

13. Quick Start Tutorial
This section will describe how to get started with associated software and set up a basic system for operation.
13.1. Network setup
13.1.1. Network connections/topology
Each frame has two network ports; a primary and a secondary. See the below diagram for a typical network
topology using the primary ports.
By default, the secondary ports are congured in Dual redundancy mode to support a second redundant network.
The alternate conguration for the two ports is a switch mode which allows daisy-chaining devices in a single
network. Daisy chain mode is not recommended for more than a few devices, and for not more than two if running
Dante audio along with control data.

NOTE: If using Dante audio in the network, the audio trafc needs to be ltered from reaching the wireless links.
13.1.2. Network configuration
Frames are congured by default to obtain IP addresses automatically. The frame will assign itself an IP address
in the link local range (169.254.1.0 through 169.254.254.255). If a computer is congured the same way
(which should be default on modern operating systems), it will reside in the same subnet as the devices and
communication can be established. Alternate congurations would be DHCP for a managed network or xed IP.
To connect to the secondary network in Dual redundancy mode the computer shall be congured with an IP
address in the 172.31.0.0 - 172.31.255.255.

13. Quick Start Tutorial
13.3. System setup
This tutorial provides a step-by-step guide for conguration of a typical professional loudspeaker system and
provides an overview of the basic features and operation of the frame. This tutorial describes how to congure
4-channel frame for use with a generic 3-way loudspeaker system (with separate HF, MF and LF drivers), plus
a separate subwoofer. It assumes that the system is fed with analog outputs from a mixing console with one
fullrange main output and a separate sub feed.
1. Connect the loudspeakers to the four power output channels:
a. Channel 1 – Low Frequency Driver
b. Channel 2 – Mid Range Driver
c. Channel 3 – High Frequency Driver
d. Channel 4 – Subwoofer
2. Connect the main output of the mixing console to analog input 1 of the frame and the sub feed to input 2.
While conguring, it is a good practice to make sure the volume is turned down on the console.
3. Ensure the frame is powered on and is in its default state, and that the computer has established an active
Ethernet connection.
4. On the Tablet PC, launch the Lake Controller software application. Select the appropriate network adapter if
more than one is enabled, and tap NO to the dialog asking whether to load the previous conguration.
5. Tap MODULES button on the menu bar at the bottom of the screen to access the Module Menu and scroll
bar.
6. On the Module scroll bar, the frame is represented with a frame containing four discs. These are labeled A, B,
C and D, each representing one of the four Lake processing modules.
7. Tap the frame to select it, then tap again in the MAIN area of the screen to place all modules of the frame in
the current system conguration. The Lake Controller uploads settings from the frame.
8. Tap the icon for Module A; its border will turn yellow to conrm selection and an LED on the front panel of the
associated device will illuminate.
9. Tap the Module Store/Recall button on the Modules Menu; the menu will change to show additional options.
10. Double-tap the Default Modules folder, then double-tap the Contour Classic Crossovers folder. A set of
loudspeaker symbols will be displayed.
11. Tap CL3way, and then tap the RECALL button. This congures the DSP for the Module A as a 3-way
crossover for the 3 way speaker.
12. Tap Yes when asked to conrm that all data will be overwritten.
13. An Output conguration dialog will pop up to allow for routing of module outputs to power channels. Tap the
orange number buttons in the matrix to un-route, freeing up a power channel. Tap a blue number button at
the intersection of the appropriate module output and power channel, routing the module output to the power
channel. Proceed until you have routing according to the picture below and tap the bottom right return button
to exit the dialog.

14. The B module is already a CL1way as default and can be used to drive the sub.
15. Tap Store/Recall EXIT to return to the Modules Menu.
16. Ensuring Module A (or any other module that you want to control) is selected (yellow border), tap I/O Cong.
17. The right side of the I/O CONFIG screen displays a block diagram for the Modules. Tapping the different blue
blocks will access the conguration screens for Input mixer, Levels, Input EQ, Delay and Output EQ/Crossover
respectively. The magnifying glass at the far right end accesses the output conguration. (NOTE: Tapping the
blue return button (left arrow), or the EQ/Levels EXIT button in the menu bar returns to the I/O Cong screen
from the various conguration screens.)
Input Mixer Conguration - Drag sliders and tap ON/OFF buttons to control input mixer settings.

frequency bar to adjust crossover frequency. Crossover
types may be changed by selecting the Crossover
Functions button.
18. Tap the Input Gain button in the block diagram and unmute the Module Input Mute. Tap EQ/Levels Exit to return to
IO Cong.
19. The left side of the IO cong screen holds frame conguration and summary for Clock conguration, Input
conguration, Dante conguration, Breaker Emulation Limiter conguration and Analog Iso-Float & AES Termination
conguration. All these congurations should be correct by default for this example.
20. From I/O CONFIG, tap EVENTS & CONTROL and navigate to the STATUS tab. Unmute the power channels and
slowly increase the volume on the appropriate feed from the mixing console. Audio should now be active at the
outputs and heard through the loudspeakers. Close the Events and Control dialog with the return button and return
to the main area by tapping the I/O Cong EXIT button.
Events & Control, Status tab – Drag sliders to adjust power channel attenuation and tap mute buttons to
control power channel mute. Metering and Status monitoring is available for each power channel.

21. Repeat step 16 and 20 for the B module. On the Output EQ/Crossover, tap the Aux Output Functions
button on the menu bar and then tap LPF Enable button. Drag the Low pass lter control object on the
frequency slider just above the menu bar to an appropriate crossover frequency for the sub, e.g. 100 Hz.
Output EQ control - Add LPF/HPF and EQ lters and drag to adjust.
22. Use the control options mentioned in 17 to tune your loudspeakers. For larger systems, modules can be
placed in groups (Groups menu from the MAIN page) for control of multiple units.
23. Some features like RPM can only be congured from within CAFÉ software. Return to EVENTS & CONTROL;
from the main area hit MODULES button, select a module (e.g. Module A), tap I/O Cong, tap EVENTS &
CONTROL, and navigate to the Control tab. The CAFÉ button (next to bottom) opens the CAFÉ application
and imports and highlights the current amplier and its RPM view.
CAFÉ, RPM view – Enter power requirements for various channels and automatically congure RPM.
