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.
The DLC24 is a two-input, four-output controller that can be configured for any combination of Apogee speaker types
using proprietary software included with the unit.
Once configured, the DLC24 recalls all loudspeaker parameters on power up, no additional programming required. When
set to Front Control, it operates like a classic analog loudspeaker controller with local level control, polarity control, and
filter control, as well as signal, limit, and overload indicators.
With the addition of Apogee Digital Audio Management (ADAM) software and a PC, the user gains remote access to all
front panel controls, 12 bands of parametric equalization (per channel), over 1356 milliseconds of delay (per channel),
snapshots, a wide assortment of speaker status information plus system design capabilities (rooms, arrays, subarrays, etc.).
The DLC24 can accept either analog or digital input signal and can be networked with other DLC24's. The DLC24 and
Apogee’s APL-DSP powered loudspeakers can operate simultaneously on the same network. The DLC24 is also
designed to be compatible with other control systems.

Care and Maintenance
The plastic lens of the DLC24 employs light plate technology. Heavy oily residue, fingerprints, or scratches can allow
light to escape from the plastic lens. To clean the DLC24, first unplug the unit and then gently wipe it with a soft
cloth or facial tissue lightly dampened with water and/or a mild cleanser. Never use a paper towel since it may
scratch the acrylic lens.
The DLC24’s lens can be safely marked with China marker pencils. The writing will illuminate because of the light
plate technology. The writing can be removed by gently wiping with a dry facial tissue. The rest of the DLC24 unit can
be cleaned using a mild soap and a soft cloth.
After cleaning, make sure the DLC24 has dried completely before reconnecting it to the AC mains. All other maintenance
should be referred to qualified service personnel.

11. RS-422 Loop Connection
DLC24/PC network connection can be paralleled via this 5-pin XLR male RS-422 port,
making it possible to daisy-chain multiple DLC24 units.

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. These ports can be used for remote PC control and
for daisy-chaining additional DLC24 units.
For local PC control, an RS-232 COM port is required from the computer.
For remote control and networking of DLC24 units, an RS-422 output is
required from the computer. In most cases, the RS-422 output will be
on a terminal strip. TX+, TX-, RX+, and RX- will be used as well as ground if
available. Some interfaces allow some general communication parameters
to be set. If that is the case, then they should be set as follows: TX on,
RX on, DCE, and SIMU.
Network Wiring, Wire, and Termination
Connections
For RS-232 connection, the cable should be a “straight” 9-pin D-Sub (male)
on DLC24 end.
For RS-422 communication, the DLC24 has a 5-pin XLR female input and a
5-pin XLR male loop-through. Loop-through cables should be 5-pin XLR
male/female.
At the PC, the RS-422 network wires must be cross-connected. TX+
and TX- from the PC should attach to RX+ and RX- of the DLC24. RX+
and RX- from the PC should attach to TX+ and TX- of the DLC24. It is
important to use high-quality, properly shielded cable for this
application. The network should be terminated at the loop-through
connector of the last unit in the chain. Basic network termination consists
of two 120-ohm resistors, one from TX+ to TX- and the other from RX+
to RX-.
Input Signal Connection
The DLC24 has two balanced 3-pin XLR female input connectors for
connection of the signal input source. The inputs are labeled “IN 1” and
“IN 2”. Pin 1 is “shield”, Pin 2 is signal “+”, and Pin 3 is signal “-”, for
both analog and digital inputs signals. When the Input Selector Switch
is set to digital, only “IN 1” is active.
Note: 2 Channel digital signals are input via one connector.
Refer to Input Selector Switch (page 10) for setting analog and
digital inputs.

Output Signal Connection
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 “-”.
Output function and channel/input assignment is determined by the
configuration file uploaded into the controller. Refer to:
DLC24 Speaker Configuration Software (page 12) for more information.
Note: Bi-amped speakers will use two outputs and
tri-amped speakers will use three outputs.
Amplifier Voltage Sense Returns
The amplifier’s output voltage is monitored by the DLC24 via the pluggable
screw terminals mounted on the rear of the controller. These are the
AMPLIFIER SENSE RETURNS and are labeled 1 through 4, corresponding
to the respective DLC24 signal outputs. When the DLC24 senses a
voltage that could damage the speaker, it engages protective limiters
to prevent speaker driver damage. Complete speaker protection is not
available without this connection.
Proper Grounding & Elimination of
Ground Loops
The proper grounding of any audio system is important in order to maximize
the signal-to-noise ratio and ensure safety. Often, simply connecting the
unit to the system with the proper balanced cables will be all that is required.
However, certain interconnections may result in objectionable levels of hum at
power line fundamental frequencies and/or related harmonics due to
multiple ground paths, often called “ground loops”.
Ground loops can most commonly be eliminated by reducing the number
of paths to earth ground within a system. The DLC24 provides switches
in two places, allowing for isolation from earth ground.
First is the Input Shield Pin 1 lift switch located at the rear of the unit near
the XLR inputs. This switch “lifts” or “floats” the shield of both signal input
XLR connectors from chassis ground . Normally, balanced cable shields
are connected to earth ground via the equipment at both ends. In case of a
ground loop, it is typical practice to keep the shield connected at the
source (so as not to defeat the purpose of the shield).
Second is the Signal Ground lift switch located at the rear of the unit near
the AC inlet. This switch “lifts” or “floats” DLC24’s power supply ground with
respect to chassis ground.
The Input Shield Pin 1 lift and Signal Ground lift switch may be used
individually or together. Additionally, most audio equipment has a ground
lift of some type. Any combination of ground lifts on the DLC24 and
other equipment can be used to reduce or eliminate ground hum and will
not create a safety hazard.
Note: The output’s Pin 1 are always tied to chassis ground
regardless of the setting of these switches.

DLC24 Software Introduction
11
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 anyApogee speaker type and (2)ADAM Software, which provides remote
operational control and monitoring of the speaker system through a PC.
Note: Only one software program may be opened at a time.
DLC24 Speaker Configuration Software
The DLC24 Speaker Configuration Software enables the user to custom configure the DLC24 for use with any
Apogee speaker type. The DLC24 Speaker Configuration Software enables the user to select Apogee speaker types,
enable or disable the Polarity switch, select channels, and select inputs for each of the four outputs. Also, the user can
add channel descriptions for reference purposes in ADAM.
ADAM Software
The ADAM Software provides control and monitoring of the DLC24 through a PC, allowing the use of a wide variety of
features that would otherwise be unavailable to the user.
Note: In order to obtain full control via the ADAM software, the Control switch on the back of the unit
must be set to the “Remote” position. If set to “Remote”, the front panel controls are disabled.
Software Setup & Updates
Download the latest version of the DLC24 Speaker Configuration Software and ADAM Software from the Apogee
Sound International website, at www.apogeesound.com/software/. Click on “ADAM & DLC24 Speaker Configuration
Software” in the table. A Terms & Conditions window will pop up. After reading the agreement, click “ACCEPT”. The
software will begin to download to your computer. (Depending on your computer settings, you may need to manually
start the download to begin.) You may need to select the directory as to where you intend to save the file.
To run the software, open the directory to where you saved the file, highlight and click on the ADAM setup file. The pro-
gram will automatically open to the installation setup.
A welcome dialog box will appear. Click “Next”. A new dialog box will appear. Enter a “User Name” and an
“Organization” and check off one of the two user choices at the bottom of the dialog box (all users or single user) and
then click “Next.”
The next dialog box will ask about a
destination folder for the software. It is
recommended that all default folders be
used when installing the software. If a
different installation folder is desired,
click on “Change”. Otherwise, click on
“Next”. In the next dialog box, click
“Install”. After the software has been
installed, click “Finish”. Updates to the
software and firmware can be found on
the Apogee web site at www.apogee-
sound.com .

Software
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. An AESB has been selected for
both Output 3 and Output 4 in the example.
2. Polarity
Polarity may be enabled or disabled. When enabled, the Polarity Switch on the front panel of the DLC24
is active as is the Polarity box in ADAM. When disabled, neither the front panel switch on the DLC24
nor the Polarity box in ADAM are operable. When a subwoofer is selected, such as the AESB, “Enable”
is automatically selected, though it can be deselected. In the example, both AESB’s are enabled
whereas the AE5 is disabled. When bi-amped or tri-amped speakers are chosen, the polarity setting for all
associate d outputs will change when the active button is changed.
3. Channel Membership
Channel Membership is selected on an individual speaker basis. When a speaker requires multiple
outputs, whatever channel is selected for the first output will automatically be selected for any additional
outputs reserved for that speaker. For example, with an AE5, if “Ch A” is selected for the high
frequency (HF), “Ch A” will automatically be selected for the low frequency (LF).
4. Input Selection
Input Selection is determined on an individual speaker basis. When a speaker requires multiple outputs,
whatever input is selected for the first output will automatically be selected for any additional outputs
reserved for that speaker. In addition, when “Ch A” is selected, “In 1” is automatically selected.
Same for “Ch B” and “In 2”. However, this auto selection can be overridden. Input 1 and Input 2
“(In 1 + In 2) / 2” can also be selected for an output, such as for subwoofers requiring a mono-summed
stereo input.

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. Description of Channel A / Description of Channel B
This is the user-defined default name that will appear in the Channel and Status Windows in ADAM.
It can be renamed in ADAM.
7. Create Download File
By selecting this button, the user can save the user-created speaker configuration to a configuration
download file (.cdl). This file will be used to download the speaker configuration to the DLC24. If the file
is saved successfully, a dialog box will appear saying, “Download file created!”
8. COM 1
Select the proper COM port of the PC in order to download the configuration download file (.cdl).
9. Scan Network
Select Scan Network to search and detect any units on the network. In order for a DLC24 to be detected,
it must be properly connected to a PC using either an RS-232 or RS-422 connection. Refer to
PC Interface Connection (page 7) for more information.
10. Download
Once a unit is detected using Scan Network, select the unit and press Download. A dialog box will
appear asking, “Downloading will replace the existing configuration. Do you wish to proceed?” Press
“Yes”. If the download is successful, another dialog box will appear saying, “Download finished.”
DLC24 Speaker Configuration Software (cont’d)

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 dif-
ferent 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. It is not neces-
sary to switch between networks to control or monitor speakers on
different COM ports.
User/Designer Mode
ADAM starts in User Mode by default. In User Mode all network
monitoring functions are available, but only Master Level and
Master Mute controls are active. In Designer Mode, the user retains
all network monitoring functions while also gaining the ability to create
and control an entire system in ADAM. Designer Mode allows the
user to access features such as gain, delay, equalization, loud-
speaker status, etc.
To enter into Designer Mode, go to the View drop-down menu and
select Designer. Enter the factory default password “designer”. The
password is not case sensitive and may be changed at any time.
The user must be in Designer Mode for the Change Password
option to become active in the View drop-down menu. In the lower
right-hand corner of the window, the software will read “USER” or
“DESIGNER” depending on what mode it is in.

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. Name the room. In order to create an array, the room in
which the array can be found must be highlighted first. Once the
proper room is highlighted, select New Array under the Tree drop-
down menu. The same applies for subarrays. In order to create a
subarray, the array under which it can be found must be highlighted
first. Select New Subarray under the Tree drop-down menu. There
are no limits to the number of Rooms, Arrays, and Subarrays the
system can have.
When creating a speaker it is not necessary to highlight anything. It
will automatically appear in the “Speakers” section and then must
be dragged to the Room, Array, or Subarray.
In order to remove a room, array, subarray, or speaker, highlight the
item in question and click on the scissors icon on the toolbar and click
on “Yes” when it asks “Are you sure?
If you remove a room, array, or subarray, you will automatically
remove everything found within it.
Many of these same functions are available by right-clicking your
mouse.

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. At this point in time
the speakers should be wired up and on, the
software loaded and running in Designer
mode, and all the loudspeakers in the network
should have been discovered.
Begin by creating a room and naming it “Main
Hall”. Next, highlight the newly created room
and create anArray and name it “CTR Cluster”.
Repeat this process and create a second array
under the Main Hall and name it “Front Fill”.
For the purpose of this example, seven generic
speakers are shown to represent the center
cluster, subwoofer, and four front fill speakers.
Next, select and drag speakers into the newly
created room structure. Drag the two center
cluster speakers into the array labeled “CTR
Cluster”. Drag the four front fill speakers into
the array labeled “Front Fill”. Drag the sub-
woofer into the room labeled “Main Hall”. If
you select the “Main Hall” from the speaker
groupings menu, you will see the Room master
channel, a channel for each array, and the
panel for the subwoofer on the room level.
If you select the “CTR Cluster” from the speak-
er groupings window, you will see the array
master channel as well as the two speaker
panels that make up the array.
If a controller is not connected properly or is
not powered up, a red “X” will appear next to
any speaker associated with that controller.
When the controller is connected properly and is powered up, a green dot will appear next to each speaker associ-
ated with that controller. When a speaker is not operating in a normal manner (e.g., experiencing a clipping condition),
a red dot will appear next to the room, the array, and the subarray that the speaker is located in, as well as next to
the speaker itself.
Save the system using the “Save As” command from the File drop-down menu. Each time the software is
launched from the start menu, it will start with a new unconfigured network.
Note: If a padlock icon appears in the channel/loudspeaker panel window, then the Control Selector
Switch is in the “Front” position. To remove the lock, switch the Control Selector Switch to “Remote”.

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. Wait until the system has been laid out in the software before proceeding with
any adjustments.
Note: Settings can be lost when moving speakers from the main tree to the appropriate room or array.
If more speakers are added to the network, go to the Tree drop-down menu and select “Discover New Speakers” to make
them available. To add a speaker, go to the Tree drop-down menu and select “New Speaker” and then give it a name.
Displayed at the top of each channel status window is the channel description followed by the ID number of the controller
and the channel. It reads “AE1A-222A” at the top. The “AE1A” is the channel description given for Channel A, the “222”
is the ID number of the controller, and the “A” at the end is the channel.
Displayed at the top of each loudspeaker status window is the channel description followed by the channel and the ID
number of the controller. It reads “AE12-225B-Ch B, ID225” at the top. The “AE12” is the channel description given for
Channel B, the “225” is the ID number of the controller, and the “B” at the end is the channel
The channel description can be renamed at anytime when in Designer Mode by highlighting it in the “Speakers” window
and right-clicking on it or clicking on Tree and then Rename.

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. On Speaker 1, an additional -4 dB of gain hasbeen added
so that the total of -10 dB is displayed in the total window.
Delay
Each channel is capable of 1356 ms of delay. Delay can be individually
set for each channel or can be set for groups of loudspeakers at one
time by entering the delay in the master channel for that group of
loudspeakers. In the example, all three speakers have 12 ms of delay
set by the master channel. The 12 ms of delay also appears in each
loudspeaker’s panel under total delay. On Speaker 5, an additional 3
ms of delay has been added so that the total delay of 15 ms is
displayed in the total window.
Note: The speed of sound is generally approximated to be
1130 feet/sec (344 meters/sec). To calculate delay from
a known distance, divide the distance by the speed of
sound.
For example, 65 feet/1130 feet per second = 57.5 ms.
Equalization
Each channel contains 12 fully parametric filters. Each filter can be
a Bandpass, Highpass, Lowpass, Highshelf or Lowshelf filter.
To use the filters, first select the filter number you want to activate
or edit. In the example, #1 is selected. If the filter is available, select
“Filter Enabled”. It is now possible to select the type of filter
desired and adjust the associated parameters. The active filter will
be displayed in Red. If “Overall Response” is selected, a green
trace shows the response of all active filters being applied to that
channel. Once the filter is selected and enabled, it is also possible
to “mouse-click” in the graphical area in order to set the filter frequency
and gain.
