Amplifier and Power Requirements
The 708i and 705i models require use of an external power amplifier capable of delivering 300 watts per channel and
also Harman Professional digital signal processing. The following Harman Crown Audio power amplifiers include the
required Harman Digital Signal Processing and are recommended:

7 Series “i” Set Up Instructions

7SeriesInstalledModelsSetUpPage36/1/16
• DCi 2|300N 2 channel power amplifier
• DCi 4|300N 4 channel power amplifier
• DCi 8|300N 8 channel power amplifier
A DCi 8|300 power amplifier supplies power for up to eight speakers,
or up to four bi-amplified speakers or any combination of single and
bi-amplified speakers. A detailed owner’s manual can be downloaded
at www.crownaudio.com Crown DCi “N” networked models include
the required digital signal processing for 7 Series speaker tuning
profiles and also additional filters that can be used as room eq.
Additionally, these amplifiers accept digital signals via HARMAN BLU
link audio protocol. If you wish to use an amplifier other than the
Crown DCi Networked models specified above, you must also use a
HARMAN BSS Soundweb™ London Signal Processor. Information
about BSS Soundweb London Processors and accessories is
available at www.bssaudio.com
The Crown DCi models incorporate internal fans that are engaged full-
time ensure the operating temperature of the power amp does not
exceed specified thermal conditions. It is preferable to locate power
amplifiers outside the listening area.
Connections and Wiring
Speaker Inputs:
The 708i and 705i can be powered using a single amplifier channel or bi-amplified using separate amplifier channels
for the low frequency and high frequency drivers. The speakers are supplied with “phoenix” type Euro-block wiring
plugs installed. Remove and connect speaker wire to EITHER the plug inserted in the connector labeled Single Wire
OR the plug inserted in the connector labeled Bi-Amplified. When operating the speaker using the Single Wire
connection, the supplied plug must remain inserted in the Bi-Amplified connector. Removing this plug will prevent
single wire operation. Replacement plugs can be obtained by contacting JBL Customer Service at
www.jblpro.com/support.
Dedicated DSP device files are required for single wire and bi-amplified operation. These are available for download
at www.jblpro.com/7series.
The speakers should be connected to the power amplifier using two conductor speaker wire. We recommend the
use of high quality 12-gauge oxygen-free copper stranded wire, readily available from electronics retailers. Using 12-
gauge wire, the speaker can be placed up to 100 feet from the power amplifier.
Crown Amplifier Inputs
Signal sources should be connected to Crown power amplifiers using
balanced line level cables. Crown Power amplifiers feature balanced
analog inputs using “phoenix” type connectors. For use with XLR,
balanced ¼” TRS and other connectors, adaptors should be used.
Crown recommends using pre-built or professionally wired balanced
cables (two-conductor plus shield). Balanced wiring provides better
rejection of unwanted noise and hum; however, unbalanced line may
also be used. Use 6-pin plug-in cable ends at the amp input connectors.
A male connector is supplied for each input of your model of amplifier.
Additional connectors are available from Crown (P/N 5024623). Figure
3 shows connector pin assignments for balanced wiring and Figure 4

shows connector pin assignments for unbalanced wiring. Note that for bridged operation, only the connectors
for odd numbered channels (1,3,5,7) for each bridged pair need be wired. For BLU link audio connection,
standard Category 5e cabling can be used. To increase fault tolerance of the BLU link audio ring, the input
and the output should be connected to adjacent BLU link nodes. There is a maximum limit of 60 BLU link
nodes for each audio ring
Crown Amplifier Speaker Outputs
Crown has designed an output cover that does not need to be removed to
connect the output wiring. Crown recommends using the included spade
connectors and two- or four-conductor, 12-gauge speaker wire. DCi amplifiers
can be configured for bi-amplification of speakers, using two amp channels
per speaker. A single 8 channel Crown DCi power amplifier can power up to
eight 7 Series speakers, or provide bi-amplification for up to four speakers The
appropriate DSP Device File installs a crossover in the power amplifier. When
using 7 Series “I” speakers in bi-amplified mode, connect channel 1,3,5 or 7 of
the power amplifier to the HF inputs of the speaker and the adjacent even
number amplifier channel to the LF terminals of the speaker. Before playing
program material at high volume, confirm the amp channels are correctly
connected to the LF and HF of each speaker. To ensure proper phase of all
speakers in the system, confirm that wires connected to the amplifier terminals
are correctly connected to the corresponding terminals on each of the speakers.
Note: DCi output terminals are configured as follows for channel 1-8 outputs:
- +, + - , - + , + - , - +, + - , - + , + -
Installing a 7 Series Speaker Tuning file in the Crown Power Amplifier using a computer
7 Series “i” models require a model-specific speaker tuning file to program the DSP in the power amp. These can be
downloaded from the JBL website at www.jblpro.com/7series. The following files are available:
For Crown DCi:
A single tuning file that includes presets for LSR705i, LSR708i single wire and bi amplified operation
BSD Soundweb London:
4 individual files providing the tuning profile for LSR705i, LSR708i single wire and bi-amplified operation.
To install the file in the DCi Power amplifier, a Windows computer with Win 7 operating system is connected to the
amplifier network port via CAT 5 cable. If multiple amplifiers are used, the computer and all amplifier Ethernet ports
should be connected to an Ethernet switch using Category 5e cable. For your reference, this photo shows the
connections and controls on Crown DCi Power Amplifiers:
Note – While the DCi 8|300 power amp can operate on a 15 amp circuit, high power DCi amplifiers required 20 amp
power circuits. The power connection in above illustration is for a 20-AMP power cord connection.

On the computer, install the latest version of Harman HiQnet™ Architect Software. Audio Architect software can be
downloaded at www.jblpro.com/7series In the computer’s Windows control panel, disable Windows Firewall. Also
Disable WiFi.
Create a folder on the Windows desktop and name it “Crown DCi Files.” Download the desired file and place it in the
folder on your desktop. If the file is in .ZIP format, use a Windows .ZIP application to extract the files. Power the
amplifier ON.
Launch Audio Architect Software.
When Audio Architect is first loaded, the software will scan the
network for HiQnet devices. All devices that are discovered on
the network will be found under the ADD DEVICE tab on the left
hand tree menu. If the devices are not found, then the network
may not be configured correctly. A feature of Audio Architect
software is HiQnet NetSetter, a software tool that enables you to
discover HiQnet devices and reconfigure network settings
including IP addresses and HiQnet IDs in real-time for each
device. Its function is to configure a system of devices to
interoperate correctly on the same network and resolve conflicts
quickly and easily. The NetSetter Window is shown below.
NetSetter information is included in the DCi owner’s manual.
Select and drag the discovered Crown amplifier(s) into the the Room View – the large open space that
occupies the center of the screen.
Click the amplifier icon to see the amplifier control panel shown below. Viewing the amplifier control panel,

NOTE: Parameters of speaker tuning files are not user accessible. In the graphic above, DSP blocks containing
crossover, EQ and delay settings appear with a padlock icon to indicate these parameters cannot be modified.
Although the Limiter settings are user accessible, it is recommended the settings are not modified as they protect the
drivers.
Using Audio Architect Software to control the speakers
Harman HiQnet Audio Architect Software allows you to control all the settings in a networked amplifier and gives you
access to speaker levels, and eq filters. All the details are included in the DCi owner’s manual. In addition to the
“locked” EQ used for speaker tuning profile, eight additional bands of EQ per channel are available and can be used
as “room eq” to compensate for acoustic anomalies caused by the room.
Power ON the amps
Launch Audio Architect software. Upon power up, your power amplifiers will appear in the Devices window on
left side of the screen as “Discovered” devices. Drag these to the right into the area called “ROOM 1.
After populating Room 1 with all the required amplifiers, save Room 1 using the FILE menu at the top left of the
Audio Architect program. The “Venue” file includes all settings of all hardware in the room. Loading this file
restores all settings of your system.
Click on one amplifier in the room. The amplifier control panel will appear. To access available EQ, click on one
of the amplifier channel EQ buttons
In this example, a parametric filter is
used to remove 10 dB at 60 Hz
compensating for resonance in the
room. Low frequency shelf EQ can be
applied to restore desired LF
performance. An HF shelf can be
used to attenuate the amount of HF
response in rooms with reflective
surfaces. Available filters can be used
to compensate for screen
transmission loss or to create industry
standard response curves such as
the X Curve used in film post
production. The use of 3rd party
measurement software will allow you
to identify the exact frequencies at
which room resonance exists. Apply
EQ as needed and save the entire
room in a Venue File.
