Precautions & Safety Notes English • To reduce the risk of electric shock, disconnect the AC main power cord before installing audio cable. Reconnect the power cord only after making all signal connections. • Connect the unit only to a three-pole, three-wire grounding mains receptacle. The receptacle must be connected to a fuse or circuit breaker. Connection to any other type of receptacle poses a shock hazard and may violate local electrical codes. • Do not install the unit in wet or humid locations.
Precautions & Safety Notes (cont’d) Deutsch • Um die Gefahr eines elektrischen Schlages auf ein Minimum zu reduzieren, den Lautsprecher Kontroller vom Stromnetz trennen, bevor ein Audiosignalkabel angeschlossen wird. Das Netzkabel erst nach Herstellung aller Signalverbindungen wieder einstecken. • Den Kontroller an eine geerdete dreipolige Schuko-Netzsteckdose anschließen. Die Steckdose muss mit einem geeigneten Überlastschutz (Sicherung oder Leistungsschalter) verbunden sein.
Description DLC24 Description The DLC24 is a loudspeaker controller designed to provide the key elements that help ensure optimal loudspeaker system performance and management in a variety of live sound and fixed installation applications. The DLC24 is intended to be the last device in the signal chain before the power amplifier(s). It is usually fed signal from a mixing console, although the source may be one of a number of devices such as a tape player, CD player, or equalizer.

Connections IMPORTANT: Always make connections prior to applying power to the unit. PC Interface Connection Pin 3: RX Pin 5: Ground Pin 2: TX Connection between the DLC24 and the PC is made via an RS-232 port on the front of the unit or via the RS-422 port on the rear of the unit. A 9-pin D-sub connector is located on the front. This port can be used for local, single unit control. Two 5-pin XLR’s are located on the rear of the DLC24 unit.
RESET INPUT Connections ANALOG Output Signal Connection OUT 1 OUT 2 OUT 3 OUT 4 DIGITAL The DLC24 has four balanced 3-pin XLR male output connectors for output signal connection. Pin1 is “ground”, Pin 2 is signal “+”, and Pin 3 is signal “- ”. CONTROL Output function and channel/input assignment is determined FRONTby the configuration file uploaded into the controller. Refer to: DLC24 Speaker Configuration Software (page 12) for more information.

Placing the switch in the “lift” position may help to minimize system hum or buzz caused by ground loops. Refer to Proper Grounding & Elimination of Ground Loops (page 8) for more information.
Software DLC24 Software Introduction Updates to the DLC24 Speaker Configuration Software, ADAM software, and firmware may be downloaded from the Apogee web site at www.apogee-sound.com/software. Two software programs are needed for the DLC24. (1) The DLC24 Speaker Configuration Software, which enables the user to custom configure the DLC24 for use with any Apogee speaker type and (2) ADAM Software, which provides remote operational control and monitoring of the speaker system through a PC.
Software DLC24 Speaker Configuration Software 3 4 5 1 2 6 7 8 9 10 1. Outputs Apogee speaker types are selected from the drop-down menu next to each output. An AE5 has been selected for Output 1 in the example shown. Since the AE5 is a bi-amped speaker it requires two outputs. As a result, Output 2 has been automatically selected with Output 1 representing the high frequency (HF) of the AE5; and Output 2, the low frequency (LF) of the AE5.
Software DLC24 Speaker Configuration Software (cont’d) 5. Browse Directories may be browsed to search for Apogee speaker type configuration files (.cfg). Configuration files for all Apogee speaker types will automatically download during the software installation to a default directory recognized by the DLC24 Speaker Configuration Software during the installation process. 6.
Software After having downloaded the Speaker Configuration file to the DLC24, launch the ADAM software. ADAM Software After launching ADAM, select the COM port for the software to access the unit or network. If there are multiple COM ports for different zones, all the relevant COM ports may be selected by holding down the CTRL key while selecting the COM ports. The software will combine the information from all active COM ports and display the speakers within the software as one large network.
Software System Design, Preplanning, and Layout It is recommended that the system layout be planned in advance so that on-site system setup can be quick and effective. Loudspeakers should be placed into a tree structure consisting of Rooms, Arrays, and Subarrays. The organization of the system at this point will greatly impact how easily the system can be tuned and controlled later. Creating Rooms, Arrays, Subarrays, and Speakers Create a room by selecting New Room under the Tree drop-down menu.
Software System Example This system example is provided to efficiently outline how to utilize the system structure of ADAM. It is provided in this manual as a teaching tool and does not exist as a tutorial in the software. It includes a center cluster of two speakers in a horizontal array along with one subwoofer and four front fill speakers mounted at the stage lip.
Software Speakers After launching ADAM, the software will automatically discover speakers on the network. Each speaker will be listed in tree format by its ID # and speaker configuration description on the left-hand side of the screen (“Speakers” section). Double clicking on any speaker will bring up a panel to the right showing the general information of the speaker selected. Do not adjust any parameters at this time.
Software Gain Control Gain can be individually set for each channel or can be set for groups of channels at one time. Gain can be adjusted by dragging the fader or by entering data directly into the window labeled “Gain”. Gain must be entered as a negative number. In the example, both speakers have -6 dB of gain set by the master channel. This gain also appears in each loudspeaker’s panel under total gain.
Software Snapshots Gain, Delay, and EQ settings for a Room, Array, Subarray, or Speaker are saved via Snapshots. Snapshots can be particularly helpful for saving and recalling settings for different scenarios. Snapshots are saved directly in the ADAM Software. Resets The ADAM software includes several levels of resets. Each reset will return the settings of the entire system, room, array, or subarray, depending on which reset is chosen, back to “0”.
