Installation and Mounting of Speakers

bottom and rear panel of the speaker. Speaker dimensional drawings, location of mounting points, and

mounting hardware requirements can be found at the end of this document, The speakers can be installed

using readily available mounting brackets. A range of brackets are available from Adaptive Technologies

Group 1635 E. Burnette Street, Signal Hill, California, USA 90755 Telephone: +1 (562) 273-4239 

document.

Caution: When installing speakers, observe safe mounting practices and recommendations provided by

mounting hardware manufacturer. Do not modify the speaker enclosure.

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 Models 3SeriesInstalled SetUpPage  8/1/16 

• 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
