Speaker damage

Ampli er 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 amplifier’s 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.

Maintenance
For safe and reliable operation, the dusters on both sides of the front panel, behind the grilles, should be removed and cleaned regularly to ensure maximum air ow through the device.
If the dust filters are not maintained there will be safety risks; for example, high internal temperatures could ignite the dust and start are. There is also a risk that the unit will malfunction since it is dependent on constant air ow from front to rear. If the dust filters are not clean and the unit malfunctions, any resulting problems will not be covered by the warranty.

Installation

Unpacking

Carefully open the shipping carton and check for any damage to the device or the supplied accessories. Every Lab.gruppen product is tested and inspected before leaving the factory and should arrive in perfect condition. If any damage is discovered, please notify the shipping company immediately. Only the consignee may initiate a claim with the carrier or their insurers for damage incurred during shipping. Save the carton and packing materials for the carrier’s inspection.

Included in the box

In addition to the D Series device, the shipping carton includes the following items:

• D Series Lake Quick Start Guide (this document)
• AC mains lead (power cable) with Neutrik powerCON connector (D 200, D 120 and D 80) or locking IEC connector (D 40, D 20 and D 10) and AC socket plug according to ordering selection
• Rear brackets for additional rear rack support (pair) along with associated mounting hardware
• Connector kit including all needed connectors
• The front grille and dust filter 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 the shipping of the device should the need arise.

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.
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 thing options fixed and removable installation. The support brackets are reversible and may bet 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.

Rear support bracket with mounting hardware

Rear support bracket mounted for removable installation and bracket pointing towards the back

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 allow maximum possible air ow. The exterior front panel is held in place by powerful magnets but is easy to detach by using your ngers in the openings at each side. To clean the foam later, detach it from the exterior front and gently use a vacuum cleaner or gently shake it. Remount with the opposite procedure. Never operate the amplifier without the dust later installed.

Cooling and fan operation

D Series devices use a forced-air cooling system with air ow 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 air ow.  Make sure an adequate air supply is provided in front of the D Series device, and that the rear of the device has sufficient 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 signi cant negative impact on the expected lifetime of 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, con rm that all other equipment also uses front-to-rear air ow for cooling. If this precaution is not observed, there is a risk of overheating, as units with the reverse air ow will be drawing in air that has already been heated by the D Series devices.
The D Series device is equipped with a sophisticated temperature sensing system that protects it from any overheating which may occur as a result of inadequate ventilation.

Operating voltage

D Series has a universal power supply and its mains nominal and operating voltages are specified in the Technical Speci cations (Section 15). D Series can be ordered with a variety of mains plugs. If the mains plug (AC plug) tied to the mains cable (AC cord) is not appropriate for your country it can be removed and a locally sourced one fitted instead. If you are not 100% con dent of your competence to replace the mains plug (AC plug), the task should be carried out by qualified 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.

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 efciency at higher voltages. For regions with nominal voltage below 140 V, one could consider connecting the amplifier in a three-phase delta or two-phase split-phase configuration, especially applicable for the bigger models, (D 200, D 120, and D 80).

NOTE: Following connections applicable only for resulting voltage inside the amplifiers nominal voltage range.

Connecting the amplifier in a three-phase delta configuration
In a three-phase configuration where the phases are 120 degrees apart, one can connect three balanced loads in a delta configuration. The connection is made between the phases instead of between the neutral and a phase.

Three-phase delta configuration
Connecting the amplifier in a split-phase configuration
In a two-phase split-phase configuration, there are two phases separated by 180 degrees. Connecting between the phases gives double the line voltage.

Two-phase split-phase configuration

Grounding

D Series must be grounded (earthed) with the safety ground pin to the mains distribution system.
NEVER disconnect the earth (ground) pin on the mains cable (AC power cord).
Use correctly-shielded balanced audio input connections to minimize hum and interference.

System configration tutorial

This section will describe how to get started with associated software and set up a basic system for operation.

Network setup

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 configured in dual redundancy mode to support a second redundant network.
The alternate configuration 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.

Network configuration

Frames are configured 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 configured the same way (which should default on modern operating systems), it will reside in the same subnet as the devices and communication can be established. Alternate configurations would be DHCP for a managed network or fixed IP. To connect to the secondary network in dual redundancy mode the computer shall be configuard with an IP address in the 172.31.0.0 – 172.31.255.255.

Software installation and firmware update

System setup

This tutorial provides a step–by–step guide for con duration of a typical professional loudspeaker system and provides an overview of the basic features and operation of the frame. This tutorial describes how to configure 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 full-range 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 con during, 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.
