• 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
