Section 4: System Connections
ANALOG AUDIO SIGNAL CONNECTIONS
The 7 Series powered models are equipped with a balanced XLR female input allowing connection to professional
audio production equipment with balanced outputs such as computer audio interfaces, mixing consoles and also
products with unbalanced outputs including personal music players, consumer audio receivers and audio visual
equipment. Connect equipment with balanced outputs to the XLR input of the speaker using balanced signal
cables. Alternately connect equipment with unbalanced outputs to the XLR female connector using unbalanced
cables. The speaker includes software-selectable +4 dBU Input sensitivity for connection of high-output
professional equipment and -10 dBV input sensitivity that provides additional gain for products with consumer-level
signal output. The desired setting is selected using the rear panel controls. See Section 5 for details.
DIGITAL AUDIO SIGNAL CONNECTIONS
705P and 708P speakers include an XLR female connector that accepts digital signals in two-channel AES3 format.
Adjacent to this connector, an XLR male digital "Pass-Through" connector is provided allowing the identical digital
signal to be connected to other speakers in the system. Use of 110 ohm cable is recommended. A maximum of
four JBL 7 Series speakers can be serially connected using the digital Pass-Through connectors.
Selective monitoring of the sources, Analog, AES channel A or AES channel B is achieved using the rear panel
controls. See Section 5 for details.

POWER CONNECTIONS

The 7 Series powered models incorporate a universal power supply allowing these to be used domestically and
internationally. The ground terminal of the IEC plug is required by wiring codes and regulations and must always
be connected to the electrical installation safety ground. Power Cords are provided with Edison and Shuko type
grounded plugs.

MAKING SOUND

After the speakers are connected to the audio system, reduce the output level of the audio source (for instance, a
mixing console, computer recording system, or preamp) to a minimum setting. Set the 7 Series POWER SWITCH
to the "ON position." After a short delay the POWER INDICATOR on the front of each speaker will illuminate and
the speakers will be ready to reproduce audio signals. Adjust the level of the playback system to produce a suitable
level at the listening position. Individual speaker levels can be adjusted in 1/10th dB increments using the rotary
control on the back of each speaker.
NOTE: 7 Series powered models include software enabled features that can be set by the user according to the
application and user-preference. To restore the factory default settings 1.set the POWER SWITCH to the OFF
position. 2. Press and Hold the MENU and BACK keys simultaneously while setting the POWER SWITCH to the ON
position. Text in the display will confirm the speaker has been reset.
